ommended. Any strain on the refrigerant lines may cause a re-  
frigerant leak. The slab should not be tied to the building  
foundation because noise and vibration will telegraph into your  
structure.  
These units must be installed in accordance with all national  
and local safety codes. If no local codes apply, installation must  
conform with the appropriate national codes. See Table 1 for  
Unit Application Data. Units are designed to meet National  
Safety Code Standards. If components are to be added to a  
unit to meet local codes, they are to be installed at the dealer's  
and/or the customer's expense.  
A unit can also be supported by concrete piers. These piers  
should (1) extend below the frost line, (2) be located under the  
unit's four corners, and (3) be sized to carry the entire unit  
weight. Refer to Figure 1 and Table 2 for the center of gravity  
and unit weight.  
LOCATION  
CAUTION: Care should be taken to protect the unit from tam-  
pering and unauthorized persons from injury.

Use the following guidelines to select a suitable loca-  
tion for these units.  
1. The condensing unit is designed for outdoor installation  
only. The condenser fans are the propeller type and are not  
suitable for use with duct work.  
2. The condensing unit and the evaporator blower should be in-  
stalled as close together as possible and with a minimum  
number of bends in the refrigerant piping. Refer to “REFRIG-  
ERANT PIPING” for additional information.  
3. The condensing unit should not be installed where normal  
operating sounds may be objectionable. On either rooftop  
or ground level installations, rubber padding can be applied  
between the base rails and their supports to lessen any  
transmission of vibration.  
FIG. 1 - CENTER OF GRAVITY  
Rig the unit by attaching nylon straps with hooks to the lifting  
holes provided in the base rails. Spreaders, whose length ex-  
ceeds the largest dimension across the unit, MUST be used  
across the top of the unit if the rigging height above the top of  
the unit is less than 5 feet. See Figure 2.  
ROOF-TOP LOCATIONS  
Be careful not to damage the roof. Consult the building contrac-  
tor or architect if the roof is bonded. Choose a location with ade-  
quate structural strength to support the unit.  
The condensing unit must be mounted on solid level supports.  
The supports can be channel iron beams or wooden beams  
treated to reduce deterioration.  
A minimum of two (2) beams are required to support each unit.  
The beams should: (1) Be positioned perpendicular to the roof  
joists. (2) Extend beyond the dimensions of the unit to distribute  
the load on the roof. (3) Be capable of adequately supporting the  
entire unit weight. Refer to Center of Gravity and Point Load Fig-  
ures and Physical Data Table for load distribution and weights.  
WARNING:Do not use straps under the unit or through the fork  
lift slots for lifting purposes. Sharp metal edges can  
damage the straps and could result in personal in-  
jury or equipment damage.  
BEFORE LIFTING A UNIT, MAKE SURE THAT ITS WEIGHT  
IS DISTRIBUTED EQUALLY ON THE STRAPS SO THAT IT  
WILL LIFT EVENLY.  
Units may also be moved or lifted with a fork-lift. Slotted open-  
ings in the base rails are provided for this purpose. The 7-1/2  
ton unit may be lifted from either the LH or RH side - under the  
unit.  
These beams can usually be set directly on the roof. Flashing is  
not required.  
NOTE: On bonded roofs, check for special installation require-  
ments.  
LENGTH OF FORKS MUSTBE AMINIMUM OF 42" for 7-1/2 ton  
units or a MINIMUM OF 54" for 10 ton units when lifting across  
the long dimension.  
GROUND LEVEL LOCATIONS  
The units must be installed on a one-piece level concrete slab  
with a minimum thickness of 4 inches. The length and width  
should be at least 6 inches greater than the units overall base  
dimensions. Refer to Figure 4.  
Remove the nesting brackets from the four corners on top of  
the unit. All screws that are removed to take these brackets off  
must be replaced on the unit.

CONTROL WIRING  
Refer to Figure 4 for the location of the control wire access  
opening through the front of the unit.  
Route the necessary low voltage control wires (18 AWG min.)  
from the TB1 terminal block inside of the unit control box  
through this access opening to the room thermostat and to the  
evaporator blower motor controller.  
The room thermostat should be located on an inside wall ap-  
proximately 56" above the floor where it will not be subject to  
drafts, sun exposure or heat from electrical fixtures or appli-  
ances. Follow manufacturer's instructions enclosed with ther-  
mostat for general installation procedure.  
FIG. 2 - TYPICAL RIGGING (7-1/2 Ton Shown)  
CLEARANCES  
Refer to Figure 3 for typical field wiring.  
All units require certain minimum clearances for proper opera-  
tion and service. Refer to Figure 4 for these clearances.  
COMPRESSOR  
Units are shipped with compressor mountings factory-  
adjusted and ready for operation.  
WARNING:Do not permit overhanging structures or shrubs to  
obstruct condenser air discharge.  
CAUTION: Do Not loosen compressor mounting bolts.  
Additional height may be required for snow clearance if winter  
operation is expected.  
COMPRESSOR CRANKCASE HEATER (7-1/2 & 10  
ton units only)  
POWER AND CONTROL WIRING  
The compressor is equipped with a crankcase heater  
to prevent refrigerant from mixing with crankcase oil  
during the “OFF” cycle. The heaters will be energized  
when the compressor is not running providing the unit  
disconnect switch is closed.  
Install electrical wiring in accordance with the latest National  
Electrical Code (NFPA Standard No. 70) and/or local regula-  
tions. The unit should be grounded in accordance with these  
codes.  
CAUTION: Do not attempt to start the compressor without at  
least eight hours of crankcase heat or compressor  
damage will occur.  
POWER WIRING  
Check the voltage of the power supply against the data on the  
unit nameplate. Check the size of the power wire, the discon-  
nect switch and the fuses against the data on Table 3.  
If a unit has just been installed or the unit disconnect switch has  
been open for a long period of time, move the system switch on  
the room thermostat to the “OFF” position before closing the  
unit disconnect switch. Eight hours of crankcase heat are re-  
quired to drive the liquid refrigerant out of the compressor bef-  
ore the compressor can be started.  
NOTE: Copper conductors must be installed between the dis-  
connect switch and the unit.

GENERAL GUIDELINES  
Many service problems can be avoided by taking adequate  
precautions to provide an internally clean and dry system and  
by using procedures and materials that conform with estab-  
lished standards.  
Use hard drawn copper tubing where no appreciable amount of  
bending around pipes or other obstructions is necessary. Use  
long radius ells wherever possible with one exception—short  
radius ells for the traps in all suction risers. If soft copper is  
used, care should be taken to avoid sharp bends which may  
cause a restriction.  
Pack fiber glass insulation and a sealing material such as per-  
magum around refrigerant lines where they penetrate a wall to  
reduce vibrations and to retain some flexibility.  
Support all refrigerant lines at minimum intervals with suitable  
hangers, brackets or clamps.  
NOTE: Never base refrigerant line sizes on the O.D. of the  
suction and liquid connections on the unit.  
Tables 4 and 5 list friction losses for both the suction and liquid  
lines on the system. Table 6 shows the amount of refrigerant  
charge required per foot of refrigerant line.  
Whentheevaporatorcoilisbelowthecondensingunit, thesuc-  
tion line must be sized for both pressure drop and for oil return.  
For certain piping arrangements, different suction line sizes  
may have to be used. The velocity of the suction gas must al-  
ways be great enough to carry oil back to the compressor.  
Braze all copper to copper joints with Silfos-5 or equivalent  
brazing material. Do not use soft solder.  
Insulate all suction lines with a minimum of 1/2" ARMAFLEX or  
equal. Liquid lines exposed to direct sunlight and/or high tem-  
peratures must also be insulated.  
Never solder suction and liquid lines together. They can be  
taped together for convenience and support purposes, but they  
must be completely insulated from each other.  
Afilter-drier MUST be installed in the liquid line of every system  
to prevent dirt and moisture from damaging the system. A  
properly-sized filter-drier is shipped with each condensing unit  
for field installation near the evaporator coil. The filter-drier and  
is taped to the top of the compressor.  
When the condensing unit is below the evaporator coil, the liq-  
uid line must be designed for the pressure drop due to both fric-  
tion loss and vertical rise. If the total pressure drop exceeds 40  
psi, some refrigerant may flash before it reaches the thermal  
expansion valve. This flashing will not only cause erratic valve  
operation and poor system performance, but could also dam-  
age the expansion valve.  
SERVICE VALVES  
These condensing units have service valves on both the com-  
pressor suction connection and the liquid line leaving the con-  
denser coil.  
The liquid and suction line service valves are shipped from the  
factory front-seated and closed with the valve stem in the maxi-  
mum clockwise position.  
NOTE: Installing a filter-drier does not eliminate the need for  
the proper evacuation of a system before it is  
charged.  
A moisture indicating sight-glass may be field installed in the  
liquid line(s) between the filter-drier and the evaporator coil.  
The moisture indicating sight-glass can be used to check for  
excess moisture in the system or used as a visual means to  
verify refrigerant charge.  
Both of the service valves have a 1/4" male flare access port for  
evacuating, charging and pressure checking the system.  
NOTE: Never remove a cap from an access port unless the  
valve is fully back-seated with its valve stem in the  
maximum counter-clockwise position because the re-  
frigerant charge will be lost. ALWAYS USE A RE-  
FRIGERATION VALVE WRENCH TO OPEN AND  
CLOSE THESE SERVICE VALVES.  
LINE SIZING  
When sizing refrigerant lines for a split-system air conditioner,  
check the following:

1All horizontal suction lines should be pitched at least 1 inch every 20 feet in the direction of the refrigerant flow to aid the return of oil to the compressor.  
2Every vertical suction riser greater than 3 feet in height should have a “P” trap at the bottom to facilitate the return of oil to the compressor. Use short radius fittings for these traps.  
3Based on Refrigerant-22 at the nominal capacity of the condensing unit, a suction temperature of 40°F and a liquid temperature of 105°F.  
4Although suction lines should be sized for a friction loss equivalent to a 2°F change in saturation temperature (or approximately 3 psi), sizing the lines for the proper return of oil  
is more important.  
5These friction losses do not include any allowances for valves or fittings.

1Based on Refrigerant-22 at the nominal capacity of the condensing unit, a liquid temperature of 105°F and a suction temperature of 40°F.  
2These friction losses do not include any allowances for a strainer, filter-drier, solenoid valve, isolation valve or fittings.  
3The total pressure drop of the liquid line for both friction and vertical rise must not exceed 40 PSI. If the pressure drop exceeds 40 PSI, the liquid refrigerant could flash before it reaches the  
expansion valve. This flashing will not only cause erratic valve operation and poor system performance, but could also damage the expansion valve.

NOTE: Use only copper tubing that has been especially  
cleaned and dehydrated for refrigerant use. If the  
tubing has been open for an extended period of  
time, it should be cleaned before being used.  
EXTENDING THE SERVICE PORTS  
(Refer to Fig 7.)  
1. Loosen the screws securing the service ports in shipping  
position.  
The liquid line connections can now be brazed while maintain-  
ing a minimum flow of dry nitrogen through the piping as fol-  
lows:  
2. Push the service ports through the corner post.  
3. Tighten the screws to secure the service ports for installa-  
tion.  
1. Remove the cap from the 1/4" access port on the liquid line  
service valve.  
INSTALLATION  
2. Connect a supply of dry nitrogen to this access port.  
Since the condensing units are shipped with a holding charge  
of refrigerant-22, they can be checked for a refrigerant leak by  
depressing the stem on either of the service ports that extend  
through the cabinet. As soon as some internal pressure is re-  
lieved release the stem. DO NOT release the entire holding  
charge.  
If the unit has already lost its holding charge, it should be leak  
tested and the necessary repairs should be made. If the unit  
has maintained its holding charge, you can assume that it has  
no leaks and proceed with the installation.  
NOTE: The filter-drier should be installed in the liquid line as  
close to the evaporator coil as possible.  
Do not allow the filter-drier to be exposed to the atmos-  
phere for an extended period of time. Once it absorbs  
moisture from the atmosphere, it loses its  
effectiveness.  
3. The matched air handlers are shipped with a small R-22  
charge and they should be checked for leaks before instal-  
lation. Drill a small hole through the sealing cap or disc in  
both the liquid and suction connection. If there is a pres-  
sure release, the evaporator has no leaks and you can pro-  
ceed with installation. If the charge has been lost, the coils  
should be leak tested and the necessary repairs made.  
CAUTION: Dry nitrogen should always be supplied through a  
connection while it is being brazed or unbrazed be-  
cause the temperature required to make or break a  
brazed joint is sufficiently high to cause oxidation  
of the copper unless an inert atmosphere is pro-  
vided. The flow of nitrogen should be continued un-  
til the joint has cooled.  
4. Move the dry nitrogen supply from the access port on the  
liquid line service valve of the condensing unit to the hole  
through the suction disc on the evaporator coil.  
When making a braze connection, wrap a wet rag  
around all tubing inside the unit to help prevent  
damage to other components.  
5. Unbraze the coil's liquid line disc while maintaining a flow of  
dry nitrogen across the connection and through the hole in  
the liquid line disc.  
WARNING:The dry nitrogen should always be supplied  
through a pressure regulating valve.  
On HCE090 models only, remove the 4-1/2" x 4-1/2" patch  
plates from the piping access panel on the front of the unit to ex-  
pose the refrigerant connections.  
Before installing the liquid line between the condensing unit  
and the evaporator coil, prepare as follows:  
NOTE: If the liquid line has a solenoid valve, the valve  
should be opened manually to permit the nitrogen  
to flow freely.  
6. After the disc has been removed, burnish the external sur-  
faces and clean the internal surfaces as outlined above.  
1. Burnish the external surfaces of the liquid connection on  
the condensing unit and the end of the field-supplied piping  
for the liquid line.  
7. Move the dry nitrogen supply back to the access port on the  
liquid line service valve.  
NOTE: Clean surfaces are essential for a well-brazed con-  
nection.  
8. Braze the liquid line to the liquid connection on the evapo-  
rator coil while maintaining a minimum flow of dry nitrogen  
through the liquid line, the evaporator coil and the hole in  
the suction disc.  
2. Carefully clean the internal surfaces of the above. Any par-  
ticles left on these surfaces may lead to a future system  
malfunction.  
9. Unbraze the disc on the suction connection of the evapora-  
tor coil while maintaining the flow of dry nitrogen.

10. After the disc has been removed, burnish the external sur-  
faces and clean the internal surfaces as outlined above.  
To continue charging refrigerant, open the liquid and the suc-  
tion line service valves fully. Turn the stem of the liquid service  
valve clockwise 1/4 turn to open its access port for reading  
pressure.  
Start the compressor (after 8 hours of crankcase heat), turn the  
stem of the suction line service valve clockwise 1/4 turn to open  
its service port and continue to charge refrigerant gas through  
this suction access port until you meet the conditions shown on  
the charging curve, Fig. 8-10.  
The suction piping can now be brazed to the suction  
connection on the evaporator coil while maintaining a  
minimum flow of dry nitrogen.  
Before brazing the suction line to the condensing unit;  
Open the liquid and vapor line service valves fully to close their  
access ports after the system has been charged.  
1. Move the dry nitrogen supply to the access port on the suc-  
tion service valve of the condensing unit.  
Alternate Charging Methods  
2. Burnish the external surfaces and clean the internal sur-  
facesofboththesuctionconnectionandthesuctionpiping.  
If you are starting a unit when the ambient temperature is  
higher or lower than those shown in Fig. 8-10, either of the fol-  
lowing methods may be used.  
The suction line can now be brazed to the suction con-  
nection on the condensing unit while maintaining the  
flow of dry nitrogen.  
Method 1: Determine the total weight of the refrigerant for the  
total system by adding the required charge for the  
outdoor unit, the indoor unit and the refrigerant  
lines using information in Tables 2 (Physical Data)  
and 6 (Refrigerant Line Charge).  
After the liquid and suction lines have been installed,  
the system should be evacuated and charged.  
EVACUATION AND CHARGING  
With the liquid and suction line service valves closed, connect a  
vacuum pump through a charging manifold to the access ports  
on both the liquid and suction line service valves.  
Using the charging procedures outlined above,  
weigh the required amount of refrigerant charge  
into the unit.  
Method 2: Install a field supplied moisture indicating sight  
glass in the liquid line between the filter-drier and  
the evaporator coil.  
Note: The vacuum pump connection should be short and  
no smaller than 3/8" O.D.  
The refrigerant lines and the evaporator coil can now be evacu-  
ated to 500 Microns without disturbing the charge in the con-  
denser coil or the compressor.  
After proper evacuation and dehydration, charge refrigerant  
through the access port on the liquid line service valve allowing  
the vacuum to draw in as much refrigerant as possible.  
Using the charging procedure outlined above,  
charge refrigerant until the moisture indicating  
sight glass is clear. Add approximately 1 extra  
pound of refrigerant for the 090 and 120 or 3 extra  
pounds for the 150 to assure a liquid refrigerant  
seal at the expansion valve under all operating  
conditions. Block the flow of the condenser air, if  
necessary, to assure a head pressure of 280 psig  
during the charging procedure.  
CAUTION: Do not charge liquid refrigerant through the com-  
pressor suction connection.  
CAUTION: Do not attempt to start the compressor without at  
least 8 hours of crankcase heat or compressor  
damage will occur.  
Note: The installer should return to the job to verify the  
operating charge when the ambient temperature is  
within the conditions shown in Fig. 8-10.

START-UP  
9. Are any refrigerant lines touching each other or any sheet  
metal surface? Rubbing due to vibration could cause a re-  
frigerant leak.  
CRANKCASE HEATER  
The crankcase heaters must be energized at least 8 hours bef-  
ore starting the compressor. To energize the crankcase heat-  
ers, the main disconnect switch must be closed. During this 8  
hour period, the system switch on the room thermostat must be  
“OFF” to prevent the compressor from starting.  
10. Are there any visible signs of a refrigerant leak, such as oil  
residue?  
11. Is any electrical wire laying against a hot refrigerant line?  
CAUTION: DO NOT ATTEMPT TO START THE COMPRES-  
SOR WITHOUT AT LEAST 8 HOURS OF CRANK-  
CASE HEAT OR COMPRESSOR DAMAGE WILL  
OCCUR.  
INITIAL START-UP  
1. Supply power to the unit through the disconnect switch at  
least 8 hours prior to starting the compressor.  
Make sure that the bottom of the compressor is warm to the  
touch to prove crankcase heater operation.  
2. Move the system switch on the thermostat to the AUTO or  
COOL position.  
PRE-START CHECK  
Before starting the unit, complete the following check list:  
3. Reduce the setting of the room thermostat to energize the  
compressor.  
1. Have sufficient clearances been provided?  
4. Check the operation of the evaporator unit per the manufac-  
turer's recommendations.  
2. Has all foreign matter been removed from the interior of the  
unit (tools, construction or shipping materials, etc.)?  
5. With an ammeter, check the compressor amps against the  
unit data plate.  
3. Have the condenser fans been rotated manually to check  
for free rotation?  
6. Check for refrigerant leaks.  
4. Are all wiring connections tight?  
7. Check for any abnormal noises and/or vibrations, and make  
the necessary adjustments to correct (e.g. fan blade(s)  
touchingshroud, refrigerantlineshittingonsheetmetal, etc.)  
5. Does the available power supply agree with the nameplate  
data on the unit?  
8. After the unit has been operating for several minutes, shut off  
the main power supply at the disconnect switch and inspect  
all factory wiring connections and bolted surfaces for tight-  
ness.  
6. Is thecontrolcircuittransformersetforthepropervoltage?  
7. Have the fuses, disconnect switch and power wire been  
sized properly?  
CAUTION: DO NOT ATTEMPT TO START THE COMPRES-  
SOR WITHOUT AT LEAST 8 HOURS OF CRANK-  
CASE HEAT OR COMPRESSOR DAMAGE WILL  
OCCUR.  
8. Are all compressor hold-down nuts properly secured?  
SECURE OWNER'S APPROVAL: When the system is functioning properly, secure the owner's approval. Show him  
the location of all disconnect switches and the thermostat. Teach him how to start and stop the unit and how to adjust  
temperature settings within the limitations of the system.  
OPERATION  
UNIT OPERATION - 7-1/2, 10 & 12-1/2 TON  
When the external control calls for cooling at terminal Y1:  
SC provides a 90 second bypass of the low pressure switch  
LP to prevent nuisance lockouts during unit start-up.  
Amalfunction light (24V, 2 Amax. resistive load) can be en-  
ergized through SC, by connecting the light between termi-  
nals X and B on TB1. Terminal X will energize when SC  
locks out.  
1. The system controller (SC) is energized. The system con-  
troller starts the compressors and enables the condenser  
fans by energizing contactor 1M (and 2M on the 12-1/2 ton,  
208/230 volt models).  
3. Unit is equipped with an anti-short cycle timer to prevent  
two successive compressor starts within 5 minutes. If the  
compressor fails to start with a call for cooling and SC is not  
locked out, wail at least 6 minutes for the anti-cycle timer to  
reset.  
The single condenser fan is energized with the compressor  
on the 7-1/2 ton models.  
Condenser fan motor #1 is energized with the compressors  
on the 10 and 12-1/2 ton models while fan #2 is enabled  
with compressor operation. Fan motor #2 operation is con-  
trolled through the Ambient Temperature Switch (ATS)  
which will de-energize the motor when the ambient tem-  
perature falls below 70°F.  
NOTE: To reset the unit after a lockout:  
A. Turn the system switch on the thermostat to the “OFF”  
position and back to the “COOL” position.  
OR  
2. Safety Lockout: The system controller (SC) has a lockout  
circuit to prevent compressor short-cycling on a safety con-  
trol with automatic reset. If the high or low refrigerant pres-  
sure switches (HP or LP) open, the SC will enter lockout  
mode.  
B. Increase the set point of the room thermostat above the  
temperature in the conditioned space and return it to its  
original setting.  
14  
Unitary Products Group  
035-15407-002-B-0404  
If the unit continues to be shut down by one of its safety con-  
trols, service should be called to determine the cause of the  
problem. Repeatedly resetting the lockout circuit may  
damage the unit.  
4. All condenser fan motors and the secondary of every trans-  
former is grounded.  
5. Every unit is protected by both a high and a low pressure  
control, and these controls are self-contained. Since they  
are mounted directly on the access connections and wired  
back to the control panel, there are no capillary lines to be  
damaged.  
The following accessories are available to provide low am-  
bient operation to 0°F.  
SAFETY FEATURES  
MAINTENANCE  
CLEANING CONDENSER SURFACE  
1. All condenser fan motors have inherent protection with  
automatic reset.  
Dirt should not be allowed to accumulate on the condenser  
coils or other parts in the condenser air circuit. Clean as of-  
ten as necessary with a brush, vacuum cleaner attachment  
or other suitable means.  
2. Every compressor is internally protected against over current,  
excessive temperature and primary single phasing.  
This protection is provided by a line break motor protector that  
is mounted inside the compressor housing and is connected  
between each winding and the common terminal.  
LUBRICATION  
The fan motors for these condensing units are equipped  
with factory lubricated and sealed ball bearings. They do  
not require any maintenance.  
3. Every compressor (except HCE150 scrolls) is protected by  
crankcase heaters to prevent refrigerant from accumulat-  
ing in the crankcases of the compressor during an “OFF”  
cycle.
