less filter access, simple compressor access, permanently  
lubricated fan motors, optional disconnect switch, optional  
115-v convenience outlet, and optional hinged access  
panels.  
• Perfect Humidity™ dehumidification package (not available  
on 558F036-150 units). This factory-installed option im-  
proves the dehumidification capability of the rooftop unit and  
helps control humidity levels in the conditioned space.  
The cabinet is constructed of galvanized steel, bonderized and  
coated with a prepainted baked enamel finish. The paint finish  
is a non-chalking type, and is capable of exceeding Federal  
Test Method Standard No. 141 (Method 6061) 500-Hour Salt  
Spray Test. In addition, all internal cabinet panel surfaces are  
primed, allowing the entire unit to have a longer life and more  
attractive appearance.  
EASY MAINTENANCE AND INSTALLATION  
All Units are Factory Shipped in the Vertical Discharge  
Configuration for fit-up to standard roof curbs. (One acces-  
sory curb fits sizes 036-072; accessory curbs fit sizes 090-150  
and 155-300.) The contractor can order and install the roof  
curbs early in the construction stage, before decisions on size  
requirements have been made.  
All Units Feature Roll-Formed Baserail design with forklift  
slots on 3 sides of the unit and rigging holes for easier maneu-  
vering and installation. Stretch-wrap packaging protects the  
unit during shipment and storage.  
BRYANT MEANS TOP QUALITY AND RELIABILITY — Each  
component utilized in these units is designed and tested for a  
minimum of 15 years operation under the harshest conditions.  
Every unit is thoroughly run tested at the factory in each oper-  
ating mode and evacuated prior to final charging. Every coil is  
leak-tested with helium particles. Automated run testing allows  
accurate impartial tests and measurements which are second  
to none in the industry.  
Form No. PDS 558F.36.2  
Easily Accessible Refrigerant Access Ports on all dis-  
charge, suction, and liquid lines permit easy and accurate  
measurements.

Exclusive Durablade economizer damper design saves energy while  
providing economical and reliable cooling. A sliding plate on the face  
of the economizer controls the amount of outdoor air entering the  
system. When the sliding plate is closed, it provides a leakproof seal  
which prevents ambient air from seeping in or conditioned air from  
seeping out. It can be easily adjusted for 100% outdoor air or any  
proportions of mixed air. Design includes standard dry-bulb control  
and 30% barometric relief capability.  
A vertical EconoMi$er, 2-stage power exhaust and dedicated hori-  
zontal EconoMi$er are available for field installation.

CONTROLS  
OPERATING SEQUENCE — SIZE 036-073 UNITS  
OPERATING SEQUENCE — SIZE 090-150 UNITS  
Cooling, Units Without Economizer — When the thermostat  
calls for cooling, terminals G and Y1 are energized. The indoor  
(evaporator) fan contactor (IFC), and compressor contactor  
no. 1 (C1) are energized and the indoor (evaporator) fan motor  
(IFM), compressor no. 1, and condenser fan start. The outdoor  
(condenser) fan motor (OFM) runs continuously while unit is  
cooling.  
Cooling, Units Without Economizer — When the thermostat  
calls for cooling, terminals G and Y1 are energized. The indoor  
(evaporator) fan contactor (IFC), compressor contactor no. 1  
(C1) and outdoor fan contactor (OFC) are energized and the  
indoor (evaporator) fan motor (IFM), compressor no. 1, and con-  
denser fans start. The outdoor (condenser) fan motors (OFM)  
run continuously while unit is cooling. If the thermostat calls for  
a second stage of cooling by energizing Y2, compressor con-  
tactor no. 2 (C2) is energized and compressor no. 2 starts.  
Cooling, Units With EconoMi$er — When the outdoor-air  
temperature (OAT) is above the ECON SP set point and the  
room thermostat calls for Stage 1 cooling (R to G + Y1), the  
indoor (evaporator) fan motor (IFM) is energized and the  
EconoMi$er damper modulates to minimum position. The com-  
pressor contactor is energized to start the compressor and out-  
door (condenser) fan motor (OFM). After the thermostat is  
satisfied, the damper modulates to the fully closed position  
when the IFM is deenergized.  
Cooling, Units With EconoMi$er — When the outdoor-air  
temperature (OAT) is above the ECON SP set point and the

When the OAT is below the ECON SP setting and the room  
thermostat calls for Stage 1 cooling (R to G + Y1), the  
EconoMi$er modulates to the minimum position when the IFM  
is energized. The EconoMi$er provides Stage 1 of cooling by  
modulating the return and outdoor air dampers to maintain a  
55 F supply air set point. If the supply-air temperature (SAT) is  
greater than 57 F, the EconoMi$er modulates open, allowing a  
greater amount of outdoor air to enter the unit. If the SAT drops  
below 53 F, the outdoor air damper modulates closed to reduce  
the amount of outdoor air. When the SAT is between 53 and  
57 F, the EconoMi$er maintains its position.

If outdoor air alone cannot satisfy the cooling requirements of  
the conditioned space, and the OAT is above the MECH CLG  
LOCKOUT set point, the EconoMi$er integrates free cooling  
with mechanical cooling. This is accomplished by the strategies  
below.

Off, and Interstage delay timer.  
1. If Y1 is energized, and the room thermostat calls for Y2  
(2-stage thermostat), compressor no. 1 and OFM are ener-  
gized. The position of the EconoMi$er damper is main-  
tained at its current value.  
2. If Y1 is energized for more than 20 minutes, and Y2 is not  
energized (whether or not a 2-stage thermostat is used),  
the compressor and OFM are energized. The position of the  
EconoMi$er damper is maintained at its current value.  
2. If Y1 is energized for more than 20 minutes, and Y2 is not  
energized (whether or not a 2-stage thermostat is used),  
compressor no. 1 and OFM are energized. The position of  
the EconoMi$er damper is maintained at its current value.  
3. If Y1 is energized, and the compressor is already energized  
(see Step 2) and the room thermostat calls for Y2, the com-  
pressor continues to operate.  
3. If Y1 is energized, and compressor no. 1 is already ener-  
gized (see Step 2) and the room thermostat calls for Y2, the  
compressor continues to operate. If Y2 remains energized  
for more than 20 minutes, compressor no. 2 is energized.  
4. If the compressor is energized and the thermostat is satis-  
fied, the compressor, the OFM, and IFM are deenergized  
and the EconoMi$er modulates closed.  
NOTE: Compressor no. 2 cannot be energized unless there is a  
signal for Y2 from the space thermostat.  
When the OAT is below the MECH CLG LOCKOUT set point,  
the compressors remain off.  
4. If compressor no. 2 is energized, and the Y2 signal from the  
thermostat is satisfied, compressors 1 and 2 are deener-  
gized. Reasserting Y2 will start compressor no. 1 and (after  
a 20-minute interstage delay) compressor no. 2.  
Heating, Units Without Economizer — Upon a call for heating  
through W1, indoor (evaporator) fan contactor (IFC) and heater  
contactor no. 1 (HC1) are energized. On units equipped for  
2 stages of heat, when additional heat is needed, heater con-  
tactor no. 2 is energized through W2.  
5. If compressor no. 1 is energized and the thermostat is satis-  
fied, compressor no. 1, the OFM, and IFM are deenergized  
and the EconoMi$er modulates closed.  
Heating, Units With Economizer — When the room tempera-

equipped for 2 stages of heat, when additional heat is needed,  
HC2 is energized through W2.  
NOTE: Compressor no. 2 cannot be energized unless there is a  
signal for Y2 from the space thermostat.  
Heating, Units With Economizer — When the room thermo-  
stat calls for heat through terminal W1, the indoor (evaporator)  
fan contactor (IFC) and heater contactor no. 1 (HC1) are ener-  
gized. On units equipped for 2 stages of heat, when additional

4. If compressor no. 2 is energized, and the Y2 signal from the  
thermostat is satisfied, compressors 1 and 2 are deener-  
gized. Re-asserting Y2 will start compressor no. 1 and  
(after a 20-minute interstage delay) compressor no. 2.  
5. If compressor no. 1 is energized and the thermostat is satis-  
fied, compressor no. 1, the OFM, and IFM are deenergized  
and the EconoMi$er modulates closed.  
SEQUENCE OF OPERATION SIZES 155-300  
When the OAT is below the MECH CLG LOCKOUT set point,  
the compressors remain off.  
Cooling, Units Without EconoMi$er — When thermostat calls  
for cooling, terminals G and Y1 are energized. The indoor  
(evaporator) fan contactor (IFC) and compressor contactor no. 1  
(C1) are energized and evaporator-fan motor, compressor no. 1,  
and condenser fans start. The condenser-fan motors run con-  
tinuously while unit is cooling. If the thermostat calls for a sec-  
ond stage of cooling by energizing Y2, compressor contactor  
no. 2 (C2) is energized and compressor no. 2 starts.  
Freeze Protection Thermostat(s) — A freeze protection ther-  
mostat (FPT) is located on the top and bottom of the evaporator  
coil. It detects frost build-up and turns off the compressor, allow-  
ing the coil to clear. Once frost has melted, the compressor can  
be reenergized by resetting the compressor lockout.  
Heating, Units With EconoMi$er (If Accessory Heater is  
Installed) — When the room thermostat calls for heat, the heat-  
ing controls are energized as described in the Heating, Units  
Without EconoMi$er section. The IFM is energized and the  
EconoMi$er damper modulates to the minimum position. When  
the thermostat is satisfied, the damper modulates closed.  
Heating, Units Without EconoMi$er (If Accessory Heater is  
Installed) — Upon a call for heating through terminal W1, IFC  
and heater contactor no. 1 (HC1) are energized. On units  
equipped for 2 stages of heat, when additional heat is needed,  
HC2 is energized through W2.  
Units With Perfect Humidity™ Dehumidification Package —  
When thermostat calls for cooling, terminals G and Y1 and/or  
Y2 and the compressor contactor C1 and/or C2 are energized.  
The indoor (evaporator) fan motor (IFM), compressors, and out-  
door (condenser) fan motors (OFM) start. The OFMs run  
continuously while the unit is in cooling. As shipped from the  
factory, both Perfect Humidity dehumidification circuits are  
always energized.  
Cooling, Units With EconoMi$er — When the OAT is above  
the ECON SP set point and the room thermostat calls for  
Stage 1 cooling (R to G + Y1), the indoor-fan motors (IFM) are  
energized and the EconoMi$er damper modulates to minimum  
position. The compressor contactor and OFC are energized to  
start the compressor and outdoor-fan motor (OFM). After the  
thermostat is satisfied, the damper modulates to the fully closed  
position when the IFM is deenergized.  
If Perfect Humidity circuit modulation is desired, a field-installed,  
wall-mounted light-commercial thermidistat (with field-supplied  
relay) is required. If the thermidistat is installed and calls for the  
Perfect Humidity subcooler coil to operate, the relay switch  
closes. This energizes the 3-way liquid line solenoid valve coils  
(LLSV1 for circuit 1 and LLSV2 for circuit 2) of the Perfect  
Humidity circuits, forcing the warm liquid refrigerant of the liquid  
line to enter the subcooler coils.  
When the OAT is below the ECON SP setting and the room  
thermostat calls for Stage 1 cooling (R to G + Y1), the  
EconoMi$er modulates to the minimum position when the IFM  
is energized. The EconoMi$er provides Stage 1 of cooling by  
modulating the return and outdoor-air dampers to maintain a  
55 F supply-air set point. If the supply-air temperature (SAT) is  
greater than 57 F, the EconoMi$er modulates open, allowing a  
greater amount of outdoor air to enter the unit. If the SAT drops  
below 53 F, the outdoor-air damper modulates closed to reduce  
the amount of outdoor air. When the SAT is between 53 and  
57 F, the EconoMi$er maintains its position.  
As the warm liquid passes through the subcooler coils, it is  
exposed to the cold supply airflow coming off the evaporator  
coils and the liquid is further cooled to a temperature approach-  
ing the evaporator coil leaving-air temperature. The state of the  
refrigerant leaving the subcooler coils is a highly subcooled  
liquid refrigerant. The liquid then enters a thermostatic expan-  
sion valve (TXV) where the liquid is dropped to the evaporator  
pressure. The TXVs can throttle the pressure drop of the liquid  
refrigerant and maintain proper conditions at the compressor  
suction valves over a wide range of operating conditions.  
The liquid proceeds to the evaporator coils at a temperature  
lower than normal cooling operation. This lower temperature is  
what increases the latent and sensible capacity of the evapora-  
tor coils.  
If outdoor air alone cannot satisfy the cooling requirements of  
the conditioned space, and the OAT is above the MECH CLG  
LOCKOUT set point, the EconoMi$er integrates free cooling  
with mechanical cooling. This is accomplished by the strategies  
below.  
NOTE: Compressors have a two-minute Minimum On and Mini-  
mum Off.  
1. If Y1 is energized, and the room thermostat calls for Y2  
(2-stage thermostat), the compressor and OFC are ener-  
gized. The position of the EconoMi$er damper is main-  
tained at its current value.  
The 2-phase refrigerant passes through the evaporators and is  
changed into a vapor. The air passing over the evaporator coils  
will become colder than during normal operation as a result of  
the colder refrigerant temperatures. However, as it passes over  
the subcooler coils, the air will be warmed, decreasing the sen-  
sible capacity and reducing the sensible heat of the rooftop unit.  
2. If Y1 is energized for more than 20 minutes, and Y2 is not  
energized (whether or not a 2-stage thermostat is used),  
the compressor and OFC are energized. The position of the  
EconoMi$er damper is maintained at its current value.  
3. If Y1 is energized, and compressor no. 1 is already ener-  
gized (see Step 2) and the room thermostat calls for Y2,

a subcooler control low-pressure switch (S-LPS1 for circuit 1 or  
S-LPS2 for circuit 2) in the suction line. This low-pressure  
switch will deactivate the Perfect Humidity™ package when the  
suction pressure reaches 60 psig. The subcooler control low-  
pressure switch is an added safety device to protect against  
evaporator coil freeze-up during low ambient operation. The  
subcooler control low-pressure will only deactivate the 3-way  
liquid line solenoid valve in the Perfect Humidity circuit. The  
compressors will continue to run as long as there is a call for  
cooling, regardless of the position of the subcooler control low-  
pressure switch. The 3-way solenoid valve and the Perfect  
Humidity package will be reactivated only when the call for cool-  
ing has been satisfied, the subcooler control low-pressure  
switch has closed above 80 psig, and a new call for cooling  
exists. The crankcase heaters on the scroll compressors  
provide additional protection for the compressors due to the  
additional refrigerant charge in the subcooler.

APPLICATION DATA  
1. CONDENSATE DRAIN PAN — A sloped condensate drain  
11. MOTOR DATA — Due to Bryant’s internal unit design (draw-  
thru over the motor), air path, and specially designed  
motors, the full horsepower (maximum continuous bhp)  
listed in the Physical Data table and in each Fan Perfor-  
mance table can be utilized with extreme confidence.  
pan is supplied on all units. The condensate drain pan must  
be externally trapped. Condensate drains are located on  
both the bottom and end of the unit. The bottom drain can  
be used for thru-the-curb connections.  
2. DUCTWORK — All ductwork must be attached to flanges. If  
no flanges are present, they must be field supplied. Secure  
vertical discharge ductwork to roof curb. For horizontal dis-  
charge applications, attach ductwork to flanges. Field-  
supplied flanges can be attached to horizontal discharge  
openings and all ductwork attached to flanges.  
Using Bryant motors to the values listed in the Physical  
Data, Fan Performance, and Evaporator-Fan Motor Data  
tables will not result in nuisance tripping or premature motor  
failure. In addition, the unit warranty will not be affected.  
12. PERFECT HUMIDITY™ DEHUMIDIFICATION PACKAGE  
— This option provides greater dehumidification by further  
subcooling the hot liquid refrigerant leaving the condenser  
coil. The Perfect Humidity package consists of a subcooling  
coil located on the leaving-air side of the evaporator coil.  
The location of the coil in the indoor airstream enhances the  
latent capacity of the rooftop units by up to 40%.  
3. THRU-THE-BOTTOM SERVICE CONNECTIONS — Thru-  
the-bottom connections allow field power wires and control  
wires to enter through the basepan.  
4. THERMOSTAT — Use of 2-stage cooling thermostat is  
recommended for all units equipped with economizer.  
Many buildings suffer damage or have poor indoor-air qual-  
ity due to overly humid conditions. Building humidity must  
be controlled for the following reasons:  
5. HEATING-TO-COOLING CHANGEOVER — All units are  
automatic changeover from heating to cooling when auto-  
matic changeover thermostat and subbase are used.  
a. INDOOR-AIR QUALITY — Humidity is a major factor in  
the growth and propagation of mold and mildew in a  
building. The mold and mildew can spread quickly and  
grow in carpets and ductwork and on walls, and often  
causes cases of sick building syndrome. This syndrome  
can lead to employee absenteeism due to illness, lower  
worker productivity, and increased health care costs. The  
American Society of Heating, Refrigeration, and Air Con-  
ditioning Engineers (ASHRAE) recommends that relative  
humidity levels in buildings be maintained below 70%.  
6. AIRFLOW — Units are draw-thru on cooling and blow-thru  
on heating.  
7. MAXIMUM AIRFLOW — To minimize possibility of conden-  
sate blow-off from evaporator, airflow through units should  
not exceed 500 cfm/ton.  
8. MINIMUM AIRFLOW — Minimum airflow for cooling is  
300 cfm/ton for unit sizes 036-240, 280 cfm/ton for size 300.  
9. MINIMUM AMBIENT OPERATING TEMPERATURE —  
Minimum operating temperature for standard 036-150 units  
is 25 F, for standard 155-300 units is 40 F. With accessory  
Motormaster® or Motormaster IV control, units can operate  
at outdoor temperatures down to –20 F.  
b. COMFORT LEVELS — High humidity levels cause the  
occupied space to become uncomfortable, because  
humidity interferes with the body’s natural cooling pro-  
cess (evaporation at the skin surface).  
10. MAXIMUM OPERATING OUTDOOR-AIR TEMPERATURE  
— Maximum outdoor-air operating temperature for cooling  
is 125 F (115 F for 558F036-150 units).

APPLICATION DATA (cont)  
Refrigerant Cycle Using Perfect Humidity™ Dehumidification  
c. HUMIDITY DAMAGE — Humidity causes property  
damage, such as stained wallpaper and ceiling tiles.  
Humidity can also damage books and artwork, and cre-  
ate strong odors in carpets. In addition, humidity can  
contribute to unacceptable product quality in industrial  
processes.  
Package  
When a subcooler coil is added to the rooftop unit, the refriger-  
ant is affected in such a way that the unit latent capacity is  
increased. The refrigerant cycle follows the same path from  
point no. 1 to point no. 2 as the standard refrigerant cycle with-  
out a subcooler (see the pressure enthalpy curve). However, at  
point no. 2, the liquid refrigerant enters the subcooler coil where  
the temperature is lowered further. At point no. 2A, this sub-  
cooled liquid enters the TXV, which drops the pressure of the  
liquid. At point no. 2B, the liquid enters the fixed orifice metering  
device. The refrigerant leaves this device as a saturated vapor  
and enters the evaporator at point no. 2C. The improved refrig-  
eration effect can now be seen between point no. 2C and point  
no. 3. The increase in the total refrigeration effect is the addi-  
tional enthalpy gained from point no. 2C to point no. 3. However,  
the subcooler coil rejects this added refrigeration effect to the  
air downstream of the evaporator coil, thus maximizing the over-  
all latent effect. This improved latent effect is a direct result of  
the addition of the Perfect Humidity subcooler coil to the refrig-  
erant cycle.  
d. IMPROPER VENTILATION — Buildings in hot and  
humid geographical areas cannot be properly ventilated  
due to high humidity levels outdoors, resulting in poor  
indoor-air quality.  
e. EQUIPMENT INEFFICIENCY — Humidity can cause  
inefficient operation of refrigerators and freezers.  
f. INCREASED ENERGY COSTS — Because of high  
humidity levels and less comfortable conditions, thermo-  
stat set points are lowered to force the HVAC (heating,  
ventilation, and air conditioning) equipment to run longer  
and work harder to lower the humidity levels. Also, in an  
attempt to control humidity, system designers typically  
oversize HVAC equipment and add reheat capability to  
get the desired latent capacity. This results in higher ini-  
tial equipment costs, as well as increased energy  
expenses throughout the life of the unit.  
Latent Capacity Effects  
Refer to the psychrometric chart to see how the sensible heat  
factor decreases when the optional Perfect Humidity dehumidifi-  
cation package is installed. This chart contains data for the  
5-ton unit operation, both with and without the Perfect Humidity  
package, at 1750 cfm. Point no. 1 on the chart represents the  
return-air dry bulb (80 F) and wet bulb (67 F) conditions. Point  
no. 2 represents the supply-air conditions for a standard rooftop  
unit without the Perfect Humidity dehumidification package.  
Point no. 3 represents the supply-air conditions for a rooftop unit  
with the Perfect Humidity package. By connecting point no. 1  
and point no. 2 on the chart and finding the intersection on the  
sensible heat factor scale, the sensible heat factor is 0.73. Con-  
nect point no. 1 and point no. 3, and see that the sensible heat  
factor is 0.58. This is a 17.5% increase in latent capacity for the  
given conditions. This increase in latent capacity allows the  
rooftop units to remove more moisture from the conditioned  
space; thus lowering the humidity levels.  
Applications  
There are many different rooftop unit applications that are  
susceptible to problems caused by high humidity levels.  
Some common applications include:  
a. RESTAURANTS — The kitchen areas of restaurants  
have many humidity-producing activities, such as dish  
washing and cooking.  
b. SUPERMARKETS — High humidity levels cause ineffi-  
ciency in operation of refrigeration and freezer systems.  
c. MUSEUMS AND LIBRARIES — Humidity can damage  
books and artwork.  
d. GYMNASIUMS, LOCKER ROOMS, AND HEALTH  
CLUBS — Shower areas and human perspiration cause  
uncomfortable occupied space conditions.  
e. HOT AND HUMID CLIMATES — The southeastern  
United States is a good example of this application. The  
Perfect Humidity dehumidification package becomes  
particularly useful when increased amounts of the hot  
and humid outdoor air need to be brought into the build-  
ing for proper ventilation.  
Dehumidification Effects  
Further evidence of dehumidification can be seen by analyzing  
the pounds of water per pound of dry air found in the supply air.  
At point no. 2 in the psychrometric chart, there are 65 grains  
(0.0092 lb) of moisture per pound of dry air. At point no. 3, there  
are 58 grains (0.0083 lb) of moisture per pound of dry air. This  
is a 12.1% decrease in the amount of water in the supply air.  
13. PERFECT HUMIDITY DEHUMIDIFICATION PACKAGE  
DESIGN EFFECTS — To fully understand the operation of  
the Perfect Humidity dehumidification package, refer to the  
pressure enthalpy curve, and analyze the Perfect Humidity  
package effects on the refrigerant in the rooftop unit. The  
pressure enthalpy curve shows the refrigerant cycle for a  
rooftop unit.  
14. PERFECT HUMIDITY DEHUMIDIFICATION PACKAGE  
OPERATING PERFORMANCE — Perfect Humidity dehu-  
midification package operation does not affect the electrical  
data. The electrical data remains the same either with or  
without the Perfect Humidity package.  
Standard Unit Refrigerant Cycle  
The operating and shipping weights will be slightly  
increased with the addition of the Perfect Humidity sub-  
cooler. See the Physical Data table for added base unit  
weight with this option.  
At point no. 1 in the pressure enthalpy curve, vapor leaving the  
compressor at a high pressure and a high temperature enters  
the condenser. The condenser removes heat from the refriger-  
ant, lowers its temperature, and changes it to a liquid. At point  
no. 2, the liquid leaves the condenser and enters a fixed expan-  
sion device that lowers the pressure of the refrigerant. At point  
no. 3, the liquid enters the evaporator coil, where the refrigerant  
increases in temperature and changes back to a vapor. At point  
no. 4, the vapor leaves the evaporator and reenters the  
compressor.  
Refer to cooling performance data, both with and without  
the Perfect Humidity dehumidification package. Note the  
greatly improved latent capacity with the Perfect Humidity  
dehumidification package.  
Static pressure is also slightly affected by the addition of the  
Perfect Humidity dehumidification package. See Static  
Pressure Drop table on page 94 when using this option.

APPLICATION DATA (cont)  
15. PERFECT HUMIDITY DEHUMIDIFICATION PACKAGE  
FEATURES AND BENEFITS  
• The Perfect Humidity dehumidification package can improve  
the humidity control of your rooftop equipment by up to 40%.  
This greatly reduces the risk of sick building syndrome by  
reducing biological growth in both ductwork and the rest of  
the building.  
• The Perfect Humidity dehumidification package improves  
comfort levels in the building by better controlling the humid-  
ity. This improved comfort level allows building tenants to  
raise the cooling set point on the thermostats for accumu-  
lated energy savings.  
• Improved humidity control allows increased outdoor-air venti-  
lation in hot and humid geographical areas. Humidity control  
also helps to improve the indoor-air quality of the building.  
• The Perfect Humidity dehumidification package is factory  
installed. There are no additional field installation costs.  
There is also no need to purchase a roof curb from another  
manufacturer, as standard Bryant roof curbs will accommo-  
date the rooftop units which have the Perfect Humidity dehu-  
midification package option installed.  
• The Perfect Humidity dehumidification package is engineered  
and manufactured by Bryant for Bryant rooftop units. All  
application support, service, and warranty issues can there-  
fore be handled through one company.  
• The slightly lower sensible capacities obtained when using  
the Perfect Humidity dehumidification package allow the unit  
to operate for an extended period of time. The more the unit  
operates, the more air is exposed to the subcooling coil. This  
rooftop unit increased latent capacity results in lower relative  
humidity levels in the occupied space.  
• It is no longer necessary to oversize equipment and add  
reheat devices to properly dehumidify your building. In a typi-  
cal scenario, a building owner may need 39,000 Btuh of sen-  
sible capacity and 23,000 Btuh of latent capacity (62,000 total  
Btuh). To accomplish this without the Perfect Humidity dehu-  
midification package, a 71/2-ton unit with a reheat device  
would be necessary to attain the higher latent capacity  
required. This results in a large up-front expense to oversize  
the equipment from a standard 5-ton to a 71/2-ton unit.  
The building owner can now purchase a 5-ton unit with the  
Perfect Humidity dehumidification package for a small addi-  
tional up-front charge, and no reheat device will be necessary  
to satisfy the cooling requirements. This reduces both installa-  
tion costs and operating costs throughout the life of the  
product.  
• Better humidity control lowers the risk of humidity-induced  
property damage.  
• The Perfect Humidity dehumidification package permits build-  
ing refrigerators and freezers to operate more efficiently due  
to lower relative humidity levels. This is the perfect solution for  
supermarket applications.  
• The Perfect Humidity subcooling circuit can be operated by a  
humidity sensor. If the sensor is used, the Perfect Humidity  
circuit will then only operate when needed. If the humidity lev-  
els in the occupied space are acceptable (such as in the  
spring and fall seasons), the Perfect Humidity circuit will not  
operate. The rooftop unit is then able to operate to its full sen-  
sible potential, which provides more efficient performance  
and energy savings.  
• At lower outdoor temperatures, rooftop units with dehumidifi-  
cation devices are subject to low suction pressure conditions.  
The Perfect Humidity dehumidification package contains a  
low-pressure switch that deactivates the Perfect Humidity  
dehumidification package under low suction pressure condi-  
tions without deactivating the compressors.

SELECTION PROCEDURE (with 558F048 example)  
I DETERMINE COOLING AND HEATING REQUIRE-  
MENTS AT DESIGN CONDITIONS:  
IV DETERMINE FAN SPEED AND MOTOR HORSEPOWER  
REQUIREMENTS AT DESIGN CONDITIONS.  
Given:  
Enter Accessory/FIOP Static Pressure table on page 61 at  
selected unit size and heater kW.  
Cooling Capacity Required . . . . . . . . . . . . . . 44,000 Btuh  
Sensible Heat Capacity . . . . . . . . . . . . . . . . . 32,000 Btuh  
Required Heating Load . . . . . . . . . . . . . . . . . 50,000 Btuh  
Condenser Entering-Air  
Temperature . . . . . . . . . . . . . . . . . . .95 F Edb/78 F Ewb  
Evaporator Entering-Air  
Temperature . . . . . . . . . . . . . . . . . . .80 F Edb/67 F Ewb  
Evaporator Air Quantity . . . . . . . . . . . . . . . . . . . .1600 cfm  
External Static Pressure . . . . . . . . . . . . . . . . . 0.75 in. wg  
Heating Capacity . . . . . . . . . . . . . . . . . . . . . . 50,000 Btuh  
Power Supply (V-Ph-Hz) . . . . . . . . . . . . . . . . . . . 230-3-60  
Find that at given air quantity (1600 cfm), pressure loss is  
0.09 in. wg.  
Before entering the Fan Performance tables, calculate the  
total static pressure required based on unit components.  
From the given find:  
External static pressure  
16 kW Heater static pressure  
0.75 in. wg  
0.09 in. wg  
Total static pressure  
0.84 in. wg  
Enter Fan Performance table for the alternate motor verti-  
cal discharge unit 558F048 on page 41. At 1600 cfm and  
0.84 in. wg external static pressure, the fan speed is  
1038 rpm and the watts are 877. (Interpolation is neces-  
sary.) The alternate motor and drive is suitable.  
Edb — Entering dry bulb  
Ewb — Entering wet bulb  
II SELECT UNIT BASED ON REQUIRED COOLING  
CAPACITY.  
V DETERMINE NET COOLING CAPACITY.  
Enter cooling capacity table for 558F048 on page 36 at  
condenser entering dry bulb temperature 95 F, air entering  
evaporator at 1600 cfm, 80 F edb and 67 F ewb. The  
Cooling capacities are gross capacities and do not include  
indoor (evaporator) fan motor (IFM) heat. Use the watts  
input power to the motor calculated in “Section IV” above.  
558F048 unit will provide  
a
total cooling capacity  
of 50,500 Btuh, and a sensible heating capacity of  
35,600 Btuh. For evaporator-air temperatures other than  
80 F edb, calculate sensible heat capacity correction as  
required using the formula in the notes following the Cool-  
ing Capacities tables.  
IFM watts = 877  
Determine net cooling capacity using the following  
formula:  
Net capacity = Gross capacity – IFM heat  
NOTE: Unit ratings are gross capacities and do not  
include the effect of evaporator-fan motor heat. To calcu-  
late net capacities, see Step V.  
Btuh  
Watt  
= 50,500 Btuh – 877 Watts (3.413  
)
= 50,500 Btuh – 2992 Btuh  
III SELECT ELECTRIC HEAT.  
= 47,508 Btuh  
Heating load required is 50,000 Btuh.  
Net sensible capacity = 35,600 Btuh – 2992 Btuh  
= 32,608 Btuh  
50,000 Btuh  
3.412 Btu/W  
= 14,654 Watts of heat required  
As demonstrated above, the 558F048 with the 16.0 kW  
electric heater and an alternate motor meets the cooling  
capacity, sensible heating capacity, and heating capacity  
requirements.  
= 14.7 kW  
Enter the Electric Heating Capacities table on page 64 for  
the 558F048 at 230-3-60. The 16.0 kW electric heater  
most closely satisfies the heat required.  
To calculate kW at 230 v, use the multiplication factors  
table on page 64.  
16.0 x .918 = 14.7 kW  
16.0 x .918 x 3.413 = 50,115 Btuh gross capacity

*Heater capacity (kW) is based on heater voltage of 208 v, 240 v,  
480 v, and 600 v. Heaters are rated at 240 v, 480 v, or 600 v. If power  
distribution voltage to unit varies from rated heater voltage, heater kW  
will vary accordingly. To determine heater capacity at actual unit volt-  
age, multiply 240 v, 480 v, or 600 v capacity by multipliers found in  
table on page 64.  
= 457  
Determine maximum deviation from average voltage.  
(AB) 457 – 452 = 5 v  
(BC) 464 – 457 = 7 v  
(AC) 457 – 455 = 2 v  
†Used to determine minimum disconnect size per NEC.  
**Heaters are field installed only.  
Maximum deviation is 7 v.  
Determine percent of voltage imbalance.

% Voltage Imbalance = 100 x  
457  
††Fuse or HACR circuit breaker.  
||Fusing in single point box provides the required branch circuit  
protection.  
= 1.53%  
NOTES:  
1. In compliance with NEC requirements for multimotor and combina-  
tion load equipment (refer to NEC Articles 430 and 440), the overcur-  
rent protective device for the unit shall be fuse or HACR breaker. The  
Canadian units may be fuse or circuit breaker.  
This amount of phase imbalance is satisfactory as it is below the  
maximum allowable 2%.  
IMPORTANT: If the supply voltage phase imbalance is more than  
2%, contact your local electric utility company immediately.  
2. Unbalanced 3-Phase Supply Voltage  
Never operate a motor where a phase imbalance in supply voltage is  
greater than 2%. Use the following formula to determine the percent  
of voltage imbalance.  
% Voltage Imbalance  
max voltage deviation from average voltage

SELECTION PROCEDURE (With 551B048 Example)  
I DETERMINE COOLING AND HEATING REQUIRE-  
MENTS AT DESIGN CONDITIONS.  
IV DETERMINE FAN SPEED AND POWER REQUIRE-  
MENTS AT DESIGN CONDITIONS.  
Given:  
Before entering the Fan Performance tables, calculate the  
total static pressure required based on unit components.  
From the given and the Pressure Drop tables on page 94,  
find:  
Required Cooling Capacity (TC). . . . . . . . . . . 44,000 Btuh  
Sensible Heat Capacity (SHC) . . . . . . . . . . . . 32,000 Btuh  
Required Heating Capacity. . . . . . . . . . . . . . . 50,000 Btuh  
Condenser Entering-Air Temperature. . . . . . . . . . . . .95 F  
Evaporator Entering-Air Temperature . . . . . . . . . 82 F edb,  
67 F ewb  
External static pressure  
Electric heat  
.75 in. wg  
.09 in. wg  
Total static pressure  
.84 in. wg  
Evaporator Air Quantity . . . . . . . . . . . . . . . . . . . 1600 cfm  
External Static Pressure (ESP) . . . . . . . . . . . . 0.75 in. wg  
Electrical Characteristics (V-Ph-Hz) . . . . . . . . . . 230-3-60  
Enter the Fan Performance table for 551B048 vertical dis-  
charge unit on page 85. At 1600 cfm, the standard motor  
will deliver 1.20 in. wg static pressure and 1.15 Bhp. This  
will adequately handle the job requirements.  
II SELECT UNIT BASED ON REQUIRED COOLING  
CAPACITY.  
V DETERMINE NET CAPACITIES.  
Capacities are gross and do not include the effect of  
indoor (evaporator) fan motor (IFM) heat. To determine  
input power to the motor, convert bhp to watts using the  
Evaporator-Fan Motor Efficiency table on page 94.  
Enter the Cooling Capacities table on page 79 at con-  
denser entering temperature of 95 F, evaporator-air enter-  
ing at 1600 cfm and 80 F db and 67 F wb. The 551B048  
unit will provide cooling capacity of 48,900 Btuh and a  
sensible heat capacity of 34,700 Btuh. For evaporator-air  
temperature other than 80 F edb, calculate sensible heat  
capacity correction, as required, using the formula found in  
the notes following the Cooling Capacities tables.  
Bhp x 746 Watts/Bhp  
IFM Watts =  
Motor Efficiency  
1.15 x 746  
=
.75  
For this example:  
=
1144  
Correction factor = 1.1 x (1 – .21) x (82 – 80)  
= 1.738  
Determine net cooling capacity as follows:  
Multiply the correction factor by 1600 cfm (a total of 2781).  
From the Gross Cooling Capacities tables find that the  
sensible heat capacity at 80 F is 34.7 MBtuh (equivalent to  
34,700 Btuh). Add 34,700 and 2781 to get the corrected  
sensible heat capacity of 37.48 MBtuh (37,481 Btuh).  
Net capacity = gross capacity – IFM heat  
=
48,900 Btuh – (1144 Watts  
Btuh  
x 3.413  
)
Watts  
NOTE: Unit ratings are gross capacities and do not  
include the effect of evaporator-fan motor heat. To calcu-  
late net capacities, see Step V.  
=
=
48,900 Btuh  
44,996 Btuh  
–
3904 Btuh  
III SELECT ELECTRIC HEAT.  
Net sensible capacity = 37,481 Btuh – 3904 Btuh  
Heating load required is 50,000 Btuh.  
= 33,577 Btuh  
50,000  
= 14.6 kW of heat required  
3.413 Btuh/kW  
Determine net heating capacity as follows:  
Net capacity = gross capacity + IFM heat  
= 50,240 + 3904  
Enter the electric Heating Capacities table on page 97 for  
551B048 at 208/230 (3 phase). The accessory 16.0 kW  
heater at 240 v most closely satisfies the heating required.  
To calculate kW at 230 v, use the Multiplication Factors  
table on page 97.  
= 54,144 Btuh  
16.0 x .92 = 14.7 kW  
16.0 x .92 x 3413 = 50,240 Btuh gross capacity

3. The SHC is based on 80 F edb temperature of air entering evaporator coil.  
Below 80 F db, subtract (corr factor x cfm) from SHC.  
Above 80 F db, add (corr factor x cfm) to SHC.  
Correction Factor = 1.10 x (1 – BF) x (db – 80)

3. The SHC is based on 80 F edb temperature of air entering evaporator coil.  
Below 80 F db, subtract (corr factor x cfm) from SHC.  
Above 80 F db, add (corr factor x cfm) to SHC.  
Correction Factor = 1.10 x (1 – BF) x (db – 80)

Determine maximum deviation from average voltage.  
(AB) 457 – 452 = 5 v  
*Used to determine minimum disconnect per NEC.  
†Heater capacity (kW) is based on heater voltage of 208 v, 240 v, 480 v or 575 v.  
If power distribution voltage to unit varies form rated heater voltage, heater kW  
will vary accordingly.  
(BC) 464 – 457 = 7 v  
(AC) 457 – 455 = 2 v  
Maximum deviation is 7 v.

1. In compliance with NEC requirements for multimotor and combination load  
equipment (refer to NEC Articles 430 and 440), the overcurrent protective  
device for the unit shall be fuse or HACR breaker.  
2. Unbalanced 3-Phase Supply Voltage  
= 1.53%  
This amount of phase imbalance is satisfactory as it is below the maximum  
allowable 2%.  
Never operate  
a
motor where  
a
phase imbalance in supply voltage is  
IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact  
your local electric utility company immediately.  
greater than 2%. Use the following formula to determine the percent of voltage  
imbalance.  
3. Non-fused disconnect switch cannot be used when rooftop unit electrical  
ratings exceed 80 amps.

21. Dehumidification Package (551B Only):  
The dehumidification package is a factory-installed  
option that provides increased dehumidification by  
further subcooling the hot liquid refrigerant leaving  
the condenser coil. The package consists of a  
subcooling coil located on the leaving-air side of the  
evaporator coil. The location of this coil in the indoor  
airstream greatly enhances the latent capacity of the  
551B units.  
The package shall be equipped with crankcase  
heater(s), low pressure switch(es), and TXV(s). Low  
pressure switch(es) prevents evaporator coil freeze  
up and TXV(s) assure a positive superheat condi-  
tion. If the operation of the subcooling coil is con-  
trolled by a field-installed, wall-mounted humidistat,  
the dehumidification circuit will then operate only  
when needed. Optional field connections for the  
humidistat are made in the low voltage compartment  
of the unit control box.

interpolation, find that the rpm is 905 and the watts are  
1503.  
IV DETERMINE NET COOLING CAPACITY.  
Cooling capacities are gross capacities and do not include  
indoor (evaporator) fan motor (IFM) heat. Use the watts  
input power to the motor calculated in Section III above.  
Vertical discharge unit with optional economizer required.  
edb — Entering dry-bulb  
ewb — Entering wet-bulb  
IFM Watts = 1503  
II SELECT UNIT BASED ON REQUIRED COOLING  
CAPACITY.  
Determine net cooling capacity using the following  
formula:  
Enter Cooling Capacities table for 559F180 (page 119) at  
condenser entering temperature 95 F, evaporator air enter-  
ing at 4,500 cfm and 67 F wb. The 559F180 unit will pro-  
vide a total cooling capacity of 178,000 Btuh and a  
sensible heating capacity of 117,000 Btuh. For air entering  
evaporator at temperatures other than 80 F edb, calculate  
sensible heat capacity correction as required using the for-  
mula in the notes following the Cooling Capacities tables.  
Net capacity = Gross capacity – IFM heat  
= 178,000 Btuh – 1503 Watts  
Btuh  
(3.412  
)
Watts  
= 178,000 Btuh – 5128 Btuh  
= 172,872 Btuh  
Net sensible capacity = 117,000 Btuh – 5128 Btuh  
NOTE: Unit ratings are gross capacities and do not  
include the effect of evaporator-fan motor heat. To calcu-  
late net capacities, see Step IV.  
= 111,872 Btuh  
The calculations show that a 559F180 unit with the  
standard motor and standard low-medium static drive is  
the correct selection for the given conditions.  
III DETERMINE FAN SPEED AND POWER REQUIRE-  
MENTS AT DESIGN CONDITIONS.  
Before entering the Fan Performance tables, calculate the  
total static pressure required based on unit components.

*Heater capacity (kW) is based on heater voltage of 208 v, 240 v, 480 v, and  
600 v. Heaters are rated at 240 v, 480 v, or 600 v. If power distribution voltage to  
unit varies from rated heater voltage, heater kW will vary accordingly. To deter-  
mine heater capacity at actual unit voltage, multiply 240 v, 480 v, or 600 v capac-  
ity by multipliers found in table on page 110.  
This amount of phase imbalance is satisfactory as it is below the maximum  
allowable 2%.  
IMPORTANT: If the supply voltage phase imbalance is more than 2%, con-  
tact your local electric utility company immediately.  
†Fuse or HACR circuit breaker.  
3. MCA calculation for 559F180-300 units with electric heaters over 50 kW =  
(1.25 x IFM amps) + (1.00 x heater FLA).  
NOTES:  
1. In compliance with NEC requirements for multimotor and combination load  
equipment (refer to NEC Articles 430 and 440), the overcurrent protective  
device for the unit shall be fuse or HACR breaker. The Canadian units may  
be fuse or circuit breaker.  
2. Unbalanced 3-Phase Supply Voltage  
Never operate a motor where a phase imbalance in supply voltage is greater  
than 2%. Use the following formula to determine the percent of voltage  
imbalance.  
% Voltage Imbalance  
max voltage deviation from average voltage  
= 100 x

SELECTION PROCEDURE (with 558F240 Example)  
I DETERMINE COOLING AND HEATING REQUIRE-  
MENTS AT DESIGN CONDITIONS.  
IV DETERMINE FAN SPEED AND POWER REQUIRE-  
MENTS AT DESIGN CONDITIONS.  
Given:  
Before entering the Fan Performance tables, calculate the  
total static pressure required based on unit components.  
From the given and the Accessory/FIOP Static Pressure  
table on page 145 find:  
Required Cooling Capacity . . . . . . . . . . . . . 230,000 Btuh  
Sensible Heat Capacity . . . . . . . . . . . . . . . . 170,000 Btuh  
Required Heating Capacity . . . . . . . . . . . . . . . . . . . 75 kW  
Condenser Entering Air Temp . . . . . . . . . . 95 F (Summer)  
Evaporator Entering Air Temp . . . . . . . . . . . . . . .80 F edb,  
67 F ewb  
Evaporator Air Quantity . . . . . . . . . . . . . . . . . . . 8,000 cfm  
External Static Pressure . . . . . . . . . . . . . . . . . . 0.4 in. wg

Enter the Fan Performance table 558F240 (page 144) at  
8,000 cfm and 0.62 in. wg external static pressure. By  
interpolation, find that the rpm is 1061 and the watts are  
4552.  
Vertical discharge unit with optional economizer required.  
edb — Entering dry-bulb  
ewb — Entering wet-bulb  
V DETERMINE NET COOLING CAPACITY.  
Cooling capacities are gross capacities and do not include  
indoor (evaporator) fan motor (IFM) heat. Use the watts  
input power to the motor calculated in Section IV above.  
II SELECT UNIT BASED ON REQUIRED COOLING  
CAPACITY.  
Enter Cooling Capacities table for 558F240 (page 140 at  
condenser entering temperature 95 F, evaporator air enter-  
ing at 8,000 cfm and 67 F wb. The 558F240 unit will pro-  
vide a total cooling capacity of 249,000 Btuh and a  
sensible heating capacity of 188,000 Btuh. For air entering  
evaporator at temperatures other than 80 F edb, calculate  
sensible heat capacity correction as required using the for-  
mula in the notes following the Cooling Capacities tables.  
IFM Watts = 4552  
Determine net cooling capacity using the following  
formula:  
Net capacity = Gross capacity – IFM heat  
= 249,000 Btuh – 4552 Watts  
Btuh  
(3.412  
)
Watts  
NOTE: Unit ratings are gross capacities and do not  
include the effect of evaporator-fan motor heat. To calcu-  
late net capacities, see Step V.  
= 249,000 Btuh – 15,531 Btuh  
= 233,469 Btuh  
Net sensible capacity = 188,000 Btuh – 15,531 Btuh  
III SELECT HEATING CAPACITY OF UNIT TO PROVIDE  
DESIGN CONDITION REQUIREMENTS.  
= 172,469 Btuh  
The calculations show that a 558F240 unit with the  
standard motor and standard low-medium static drive is  
the correct selection for the given conditions.  
In the Electric Resistance Heater table (page 130) select  
the 75 kW output heater.

GENERAL FAN PERFORMANCE NOTES  
NOTES:  
motor failure. Unit warranty will not be affected. See Evaporator-Fan Motor  
Performance table on page 146 for additional information.  
3. Use of a field-supplied motor may affect wire sizing. Contact your Bryant  
representative for details.  
1. Values include losses for filters, unit casing, and wet coils. See below for  
accessory/factory-installed option static pressure information.  
2. Extensive motor and electrical testing on these units ensures that the full  
range of the motor can be utilized with confidence. Using your fan motors up  
to the wattage ratings shown will not result in nuisance tripping or premature  
4. Interpolation is permissible. Do not extrapolate.

*Heater capacity (kW) is based on heater voltage of 208 v, 240 v, 480 v, and  
600 v. Heaters are rated at 240 v, 480 v, or 600 v. If power distribution voltage to  
unit varies from rated heater voltage, heater kW will vary accordingly. To deter-  
mine heater capacity at actual unit voltage, multiply 240 v, 480 v, or 600 v capac-  
ity by multipliers found in table on page 130. Electric heaters are field installed.  
†Fuse or HACR circuit breaker.

Determine maximum deviation from average voltage.  
(AB) 457 – 452 = 5 v  
(BC) 464 – 457 = 7 v  
(AC) 457 – 455 = 2 v  
Maximum deviation is 7 v.  
Determine percent voltage imbalance.  
NOTES:  
1. In compliance with NEC requirements for multimotor and combination load  
equipment (refer to NEC Articles 430 and 440), the overcurrent protective  
device for the unit shall be fuse or HACR breaker. The Canadian units may  
be fuse or circuit breaker.

2. Unbalanced 3-Phase Supply Voltage  
This amount of phase imbalance is satisfactory as it is below the maximum  
allowable 2%.  
Never operate a motor where a phase imbalance in supply voltage is greater  
than 2%. Use the following formula to determine the percent of voltage  
imbalance.  
IMPORTANT: If the supply voltage phase imbalance is more than 2%, con-  
tact your local electric utility company immediately.

SELECTION PROCEDURE  
I DETERMINE COOLING AND HEATING REQUIRE-  
Enter the Accessory/FIOP Static Pressure — 551A155-

Enter Fan Performance tables for 551A180 at 6,000 cfm  
and 1.57 in. wg. The rpm is 1184 and the Bhp is  
4.43 (interpolation required). The factory-installed 5 hp  
motor and alternate high-static drive are sufficient for this  
operation.  
V DETERMINE NET COOLING CAPACITIES.  
II SELECT UNIT BASED ON REQUIRED COOLING  
CAPACITY.  
Cooling capacities are gross capacities and do not include  
indoor (evaporator) fan motor (IFM) heat. To determine  
input power to the motor, enter the Fan Performance  
tables for 551A180 at 6,000 cfm and 1.57 in. wg. Input  
watts to the motor are 3772 (interpolation required).  
Enter Cooling Capacities table for 551A180 at condenser  
entering temperature of 95 F, evaporator air quantity of  
6,000 cfm, and indoor air temperature of 67 F. The  
551A180 unit will provide a total cooling capacity of  
190,000 Btuh and a SHC of 136,000 Btuh. For evaporator  
air temperatures other than 80 F, calculate SHC correction  
using formula in notes under cooling capacity tables.  
Determine net cooling capacity and net sensible cooling  
capacity using the following formulas:  
IFM Heat = Input Watts x 3.412 Btuh/Watt  
= 3772 x 3.412  
Unit meets design conditions for TC and SHC.  
= 12,870 Btuh  
NOTE: Unit ratings are gross capacities and do not  
include the effect of indoor fan motor heat. To calculate net  
capacities, see Step V.  
Net Capacity = Gross Capacity – IFM Heat  
= 190,000 – 12,870  
= 177,130 Btuh  
III SELECT ELECTRIC HEAT.  
Net Sensible Cap. = Gross Sensible Cap. – IFM Heat  
= 136,000 – 12,870  
Heating load required is 110,000 Btuh.  
= 123,130 Btuh  
110,000 Btuh  
= 32,239 Watts Required  
3.412 Btu/W  
The calculations show that a 551A180 unit with the 56 kW  
heater is the correct selection for the given conditions.  
= 32.2 kW required  
VI SELECT THE UNIT THAT CORRESPONDS TO POWER  
SOURCE AVAILABLE.  
Enter the Electric Resistance Heater Data table, on  
page 150, for the 551A180 unit at 230-3-60. The 56 kW  
(52 kW at 230 v) heater most closely satisfies the heat  
required.  
The electrical data table shows that the 230-3-60 unit is  
available.  
IV DETERMINE FAN SPEED AND POWER REQUIRE-  
MENTS AT DESIGN CONDITIONS.  
Before entering the Fan Performance tables, calculate the  
total static pressure required based on unit components.  
Tabulated fan performance includes filters and wet evapo-  
rator coil. Refer to Accessory/FIOP Static Pressure table  
for added pressure drops.

motor failure. Unit warranty will not be affected. See Evaporator-Fan Motor  
Performance table on page 163 for additional information.  
3. Use of a field-supplied motor may affect wire sizing. Contact your Bryant  
representative for details.  
1. Values include losses for filters, unit casing, and wet coils. See below for  
accessory/factory-installed option static pressure information.  
2. Extensive motor and electrical testing on these units ensures that the full  
range of the motor can be utilized with confidence. Using your fan motors up  
to the wattage ratings shown will not result in nuisance tripping or premature  
4. Interpolation is permissible. Do not extrapolate.

*Heater capacity (kW) is based on heater voltage of 208 v, 240 v, 380 v, 480 v, and 575 v. Heat-  
ers are rated at 240 v, 480 v, or 575 v. If power distribution voltage to unit varies from rated  
heater voltage, heater kW will vary accordingly. To determine heater capacity at actual unit  
voltage, multiply 240 v, 480 v, or 575 v capacity by multipliers found in table on page 150.

NOTES:  
Maximum deviation is 7 v.  
1. In compliance with NEC requirements for multimotor and combination load equipment  
(refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be  
fuse or HACR breaker. The Canadian units may be fuse or circuit breaker.

Never operate a motor where a phase imbalance in supply voltage is greater than 2%.  
Use the following formula to determine the percent of voltage imbalance.  
= 1.53%  
This amount of phase imbalance is satisfactory as it is below the maximum allowable  
2%.  
IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local  
electric utility company immediately.

11. Electronic Programmable Thermostat:  
Capable of using deluxe full-featured electronic  
thermostat.  
12. Dehumidification Package:  
e. Certain models (208-230/3/60, 42/56 and 56/  
75 kW) require an additional heater control box  
that contains a field power terminal block, a field  
power wiring fuse block and fuses (125 A, 250 V,  
class K5 or RK%); included with the electric  
heater assembly package.  
The dehumidification package is a factory-installed  
option that provides increased dehumidification by  
further subcooling the hot liquid refrigerant leaving  
the condenser coil. The package consists of a sub-  
cooling coil located on the leaving airside of the  
evaporator coil. The location of this coil in the indoor  
air stream greatly enhances the latent capacity of the  
units.  
f. All power wiring leads are 10 AWG and con-  
trol wiring leads are 18 AWG, both rated at  
105 deg. C.  
The package shall be equipped with low pressure  
switch(es) and TXVs. Low pressure switch(es) pre-  
vents evaporator coil freeze-up and TXVs assure a

aluminum plate fins (590 fins/m; 15 fins/in.) and  
(41.28 mm; 1.625 in. OD) copper headers. Input and  
output connections shall be (41.28 mm; 1.625 in.  
ODM) copper stubs for sweat connections. Coil shall  
be furnished with suitable support rails, end plates,  
and hardware for ready field installation in heater  
compartment.  
22. Return Air Enthalpy Sensor:  
The return air enthalpy sensor shall be used with the  
EconoMi$er device. When used in conjunction with  
an outdoor air enthalpy sensor, the EconoMi$er  
device will provide differential enthalpy control.  
23. Return Air Temperature Sensor:  
The return air temperature sensor shall be used with  
the EconoMi$er device. When used in conjunction  
with the standard outdoor air temperature sensor,  
the EconoMi$er device will provide differential tem-  
perature control.  
19. Alternate Drive:  
Shall provide higher static drive capability to en-  
hance evaporator-fan performance rpm range.  
20. Hail Guard, Condenser Coil Grille:  
Shall protect the condenser coil from hail, flying  
debris, and damage by large objects without increas-  
ing unit clearances.  
24. Light Commercial Thermidistat:  
Field-installed wall-mounted thermidistat is used to  
control temperature and activation of the dehumidifi-  
cation package. The thermidistat can be set for  
humidity settings from 50% to 90% relative humidity.  
21. Outdoor Air Enthalpy Sensor:  
The outdoor air enthalpy sensor shall be used with  
the EconoMi$er device to provide single enthalpy  
control. When used in conjunction with a return air  
enthalpy sensor, the EconoMi$er device will provide  
different enthalpy control. The sensor allows the
