Low Ambient - An integrated low-ambient control  
allows all units to operate in the cooling mode down  
to 0°F outdoor ambient without additional assis-  
tance. Optionally, the control board can be pro-  
grammed to lockout the compressors when the  
outdoor air temperature is low or when free cooling  
is available.  
FEATURES  
All models are available with a wide variety of factory-  
mounted options such as stainless steel heat exchangers,  
phase monitor, dirty filter switch, and coil guard to make them  
suitable for almost every application.  
All units are self-contained and assembled on full perimeter  
base rails with holes in the four corners for overhead rigging.  
Every unit is completely piped, wired, charged and tested at  
the factory to simplify the field installation and to provide  
years of dependable operation.  
The S implicity® control board used in this product will  
effectively operate the cooling system down to 0°F  
when this product is applied in a comfort cooling  
application for people. An economizer is typically  
included in this type of application. When applying this  
product for process cooling applications (computer  
rooms, switchgear, etc.), please reference applications  
bulletin AE-011-07 or call the applications department  
for Unitary Products @ 1-877-UPG-SERV for  
All models (including those with an economizer) are suitable  
for either bottom or horizontal duct connections. Models with  
factory installed power exhaust are suitable for bottom  
duct connections only. For bottom duct, you remove the  
sheet metal panels from the supply and return air openings  
through the base of the unit. For horizontal duct, you replace  
the supply and return air panels on the rear of the unit with a  
side duct flange accessory.  
guidance. Additional accessories may be needed for  
stable operation at temperatures below 30°F.  
All models are available with these “factory mounted” outdoor  
air damper options:  
Anti-Short Cycle Protection - To aid compressor  
life, an anti-short cycle delay is incorporated into the  
standard controls. Compressor reliability is further  
ensured by programmable minimum run times. For  
testing, the anti short cycle delay can be temporarily  
overridden with the push of a button.  
Single enthalpy economizer with or without power  
exhaust  
BAS-ready economizer with or without power exhaust  
Motorized outdoor air damper  
Barometric Relief Damper  
Lead-Lag - An integrated Lead-Lag option allows  
equal run time hours on all compressors, thereby  
extending the life of all compressors. This option is  
selectable on the unit control board.  
A fixed outdoor air intake assembly will be shipped in the  
return air compartment of all units ordered without an econo-  
mizer or motorized outdoor air damper option. The assembly  
includes a rain hood with a damper that can be set for 10, 15  
or 25% outdoor air. With bottom duct connections, the intake  
damper assembly should be mounted over the opening in the  
return air panel. With horizontal ductwork, it should be  
mounted on the return air duct.  
Fan Delays - Fan on and fan off delays are fully pro-  
grammable. Furthermore, the heating and cooling  
fan delay times are independent of one another. All  
units are programmed with default values based  
upon their configuration of cooling and heat.  
All supply air blowers are equipped with a belt drive that can  
be adjusted to meet the exact requirements of the job. A high  
static drive option is available for applications with a higher  
CFM and/or static pressure requirement. A variable air volume  
(VAV) option using a variable frequency drive is available for  
applications requiring a constant supply duct pressure. A dif-  
ferential pressure transducer is used to monitor supply duct  
static pressure and return a speed reference signal to the VFD  
to control the output of the indoor blower motor.  
Safety Monitoring - The control board monitors the  
high and low-pressure switches, the freezestats, the  
gas valve, if applicable, and the temperature limit  
switch on gas and electric heat units. The unit con-  
trol board will alarm on ignition failures, compressor  
lockouts and repeated limit switch trips.  
Nuisance Trip Protection and Strikes - To prevent  
nuisance trouble calls, the control board uses a  
“three times, you’re out” philosophy. The high and  
low-pressure switches and the freezestats must trip  
three times within two hours before the unit control  
board will lock out the associated compressor.  
All compressors include scroll compressors and internal pres-  
sure relief. Every refrigerant circuit includes an expansion  
valve, a liquid line filter-drier, a discharge line high pressure  
switch and a suction line with a freezestat and low pressure/  
loss of charge switch to protect all system components. A hot  
gas bypass option, consisting of an adjustable compressor  
discharge bypass valve, is available for low cooling load  
applications.  
On Board Diagnostics - Each alarm will energize a  
trouble light on the thermostat, if so equipped, and  
flash an alarm code on the control board LED. Each  
high and low-pressure switch alarm as well as each  
freezestat alarm has its own flash code. The control  
board saves the five most recent alarms in memory,  
and these alarms can be reviewed at any time.  
Alarms and programmed values are retained  
through the loss of power.

Warranty - All models include a one-year limited parts  
warranty on the complete unit. Compressors and electric  
heater elements carry a five-year warranty. Gas heat  
exchangers carry a 10-year parts warranty.  
FACTORY-INSTALLED OPTIONS  
SINGLE INPUT ELECTRONIC ENTHALPY ECONO-  
MIZERS - Includes a slide-in / plug-in damper assembly  
with fully modulating spring-return motor actuator capa-  
ble of introducing up to 100% outdoor air with nominal  
1% leakage type dampers.  
Gas Heat Operation - All gas heat units are built with  
two heating sections for two equal stages of capacity  
control. Each section includes a durable heat exchanger  
with aluminized steel or optional stainless steel tubes, a  
redundant gas valve, spark ignition, power venting, an  
ignition module for 100% shut-off and all of the safety  
controls required to meet the latest ANSI standards.  
The enthalpy system contains one sensor that monitors  
the outdoor air and determines when the air is cool  
enough and dry enough to provide free cooling.  
The rainhood is painted to match the basic unit and must  
be field-assembled before installing.  
The gas supply piping can be routed into the heating  
compartment through a hole in the base pan of the unit  
or through a knockout in the piping panel on the front of  
the unit.  
BAS-READY ECONOMIZER - Includes a slide-in / plug-  
in damper assembly with fully modulating spring-return  
motor actuator with zero to 95-degree rotation capable of  
introducing up to 100% outdoor air with nominal 1% leak-  
age type dampers.  
Electric Heat Operation - All electric heat models (fac-  
tory installed only) are wired for a single power source  
and include a bank of nickel chromium elements  
mounted at the discharge of the supply air blower to pro-  
vide a high velocity and uniform distribution of air across  
the heating elements. Every element is fully protected  
against excessive current and temperature by fuses and  
two thermal limit switches.  
Actuator requires 2-10 VDC input from an external  
source, such as a field-installed or factory-installed BAS  
controller. BAS-ready actuators have an adjustable auxil-  
iary end-switch for optional power exhaust control.  
For units with optional VAV or Simplicity® Intelli-Com-  
fort™ control, a factory-installed, dry bulb sensor deter-  
mines if outdoor air temperature is low enough to provide  
free-cooling operation. (Field-installed humidity sensors  
for either outdoor air or outdoor & return air streams are  
The power supply wiring can be routed into the control  
box through a threaded pipe connection in the base pan  
of the unit or through a knockout in the wiring panel on

available for single enthalpy and differential enthalpy  
configurations, respectively).  
Blower Motor Access compartment. The switch can be  
used to either route power to the VFD for modulating  
control of the blower motor, to bypass the drive and oper-  
ate the motor at full speed, or to power the drive (and not  
the motor) for diagnostic purposes.  
The rainhood is painted to match the basic unit and must  
be field-assembled before installing.  
POWER EXHAUST - Our economizer options are avail-  
able with power exhaust. Whenever the outdoor air intake  
dampers are opened for free cooling, the exhaust fan will  
be energized to prevent the conditioned space from being  
over-pressurized during economizer operation. BAS-  
ready economizer actuators have an adjustable auxiliary  
end-switch to provide a range of damper positions available  
to energize power exhaust. For units with optional VAV,  
power exhaust is energized by means of a binary output  
signal from the unit's VAV control board.  
Due to space limitations, VAV is not available with any of  
the factory-installed BAS options described below, but is  
available with ‘BAS-ready’ models. Terminal blocks are  
provided in the control box for field wiring of the cus-  
tomer-installed BAS.  
A ‘VFD-ready’ option provides the provisions for a cus-  
tomer-installed drive. The unit comes with a mounting  
bracket installed in the Blower Access compartment  
which may accommodate other vendor’s drives depend-  
ing on their size. In order to utilize the unit’s mounting  
bracket, the maximum recommended drive dimensions  
are as follows:  
The exhaust fan, motor and controls are installed and  
wired at the factory. The rain hood must be assembled  
and installed in the field.  
For 5-hp motor applications ........................10” H x 6” W x 7” D  
For 7.5 thru 15-hp motor applications.........13” H x 8” W x 8” D  
The power exhaust option can only be used on bot-  
tom duct configurations.  
If the drive will not fit in the allotted space, then it will  
have to be mounted elsewhere; either within the building  
on a perpendicular wall which is not subjected to exces-  
sive temperature, vibration, humidity, dust, corrosive  
gas, explosive gas, etc., or within an appropriate enclo-  
sure rated for outside installation to safeguard against  
moisture, dust and excessive heat.  
MOTORIZED OUTDOOR AIR INTAKE DAMPER -  
Includes a slide-in / plug-in damper assembly with a 2-  
position, spring return motor actuator which opens to a  
pre-set position whenever the supply air blower is oper-  
ating and will drive fully closed when the blower unit  
shuts down.  
The rain hood is painted to match the basic unit and  
must be field assembled before installing.  
A terminal block located in the control box is provided for  
field connection of the VFD controls.  
BAROMETRIC RELIEF DAMPER - This damper option  
can be used to relieve internal building air pressure on  
units with an economizer without power exhaust. This  
accessory includes a rain hood, a bird screen and a fully  
assembled damper. With bottom duct connections, the  
damper should be mounted over the opening in the  
return air panel. With horizontal ductwork, the accessory  
should be mounted on the return air duct.  
HOT GAS BYPASS - To allow for low cooling load oper-  
ation, a direct-acting pressure-modulating bypass control  
valve installed on the system #1 discharge line is used to  
divert high temperature, high pressure refrigerant around  
the TXV in order to maintain a desired minimum evapo-  
rator pressure. HGBP is standard on all units with VAV  
and optional with CV units.

The rain hood is painted to match the basic unit and  
must be field assembled before installing.  
BURGLAR BARS - Mount in the supply and return  
openings to prevent entry into the duct work.  
ROOF CURBS - Fourteen-inch high roof curbs provide a  
water-tight seal between the unit and the finished roof.  
These full perimeter curbs meet the requirements of the  
National Roofing Contractors Association (NRCA) and  
are shipped knocked-down for field assembly.  
FLUE EXHAUST EXTENSION KIT - In locations with  
wind or weather conditions which may interfere with  
proper exhausting of furnace combustion products, this  
kit can be installed to prevent the flue exhaust from  
entering nearby fresh air intakes.  
They're designed to fit inside the base rails of the unit  
and include both a wood nailing strip and duct hanger  
supports.  
WOOD SKID - Allows unit to be handled with 90” forks.  
CO SENSOR - Senses CO levels and automatically

present limits.  
COIL GUARD - Customers can purchase a coil guard kit  
to protect the condenser coil from damage. This is not a  
hail guard kit.  
PROPANE - Burner orifices, pilot orifices and gas valve  
parts are provided to convert a natural gas furnace to  
propane.  
PHASE MONITORS - Designed to prevent unit damage.  
The phase monitor will shut the unit down in an out-of-  
phase condition.

order to use the indoor blower tables for high altitude applica-  
tions, certain corrections are necessary.  
CFM, STATIC PRESSURE, AND POWER - ALTI-  
TUDE AND TEMPERATURE CORRECTIONS  
A centrifugal fan is a "constant volume" device. This means  
that, if the rpm remains constant, the CFM delivered is the  
same regardless of the density of the air. However, since the  
air at high altitude is less dense, less static pressure will be  
generated and less power will be required than a similar  
application at sea level. Air density correction factors are  
shown in Table 8 and Figure 2.  
The information below should be used to assist in application  
of product when being applied at altitudes at or exceeding  
1000 feet above sea level.  
The air flow rates listed in the standard blower performance  
tables are based on standard air at sea level. As the altitude  
or temperature increases, the density of air decreases. In

The examples below will assist in determining the airflow per-  
formance of the product at altitude.  
blower tables to select the blower speed and the BHP  
requirement.  
Example 1: What are the corrected CFM, static pressure,  
and BHP at an elevation of 5,000 ft. if the blower performance  
data is 6,000 CFM, 1.5 IWC and 4.0 BHP?  
Solution: As in the example above, no temperature informa-  
tion is given so 70°F is assumed.  
The 1.5" static pressure given is at an elevation of 5,000 ft.  
The first step is to convert this static pressure to equivalent  
sea level conditions.  
Solution: At an elevation of 5,000 ft the indoor blower will still  
deliver 6,000 CFM if the rpm is unchanged. However, Table  
8 must be used to determine the static pressure and BHP.  
Since no temperature data is given, we will assume an air  
temperature of 70°F. Table 8 shows the correction factor to be  
0.832.  
Sea level static pressure = 1.5 / .832 = 1.80"  
Enter the blower table at 6000 sCFM and static pressure of  
1.8". The rpm listed will be the same rpm needed at 5,000 ft.  
Corrected static pressure = 1.5 x 0.832 = 1.248 IWC  
Corrected BHP = 4.0 x 0.832 = 3.328  
Suppose that the corresponding BHP listed in the table is 3.2.  
This value must be corrected for elevation.  
Example 2: A system, located at 5,000 feet of elevation, is to  
BHP at 5,000 ft = 3.2 x .832 = 2.66  
deliver 6,000 CFM at a static pressure of 1.5". Use the unit

NOTES: 1. Blower performance includes a gas-fired heat exchanger, fixed outdoor air, two-inch T/A filters and a dry evaporator coil.  
2. Refer to the additional Static Resistances table.  
ESP = External Static Pressure available for the supply and return air duct system. All internal unit resistances have been deducted from the  
total static pressure of the blower.  
* Do NOT close the pulley below 1 turn open.  
** Factory setting.  
15 HP Motor is required.

1. All motors have a nominal speed of 1800 RPM, a 1.15 service factor and a solid base. They can operate to the limit of their service factor because  
they are located in the moving air, upstream of any heating device.  
2. Do NOT close this pulley below 1 turn open.

1. Deduct theses resistance values from the available unit ESP values listed in the respective blower performance table except for  
Horizontal Duct Connections.  
2. Since the resistance to air flow will be less for horizontal duct connections than for bottom duct connections, add these pressures  
to the ESP values on the respective unit’s blower performance table.

supply/return, and be available with factory installed options  
or field installed accessories. The units shall be factory  
wired, piped, charged with R-22 refrigerant and factory  
tested prior to shipment. All unit wiring shall be both num-  
bered and color coded. All units shall be manufactured in a  
facility certified to ISO 9001 standards and the cooling per-  
formance shall be rated in accordance with DOE and ARI  
test procedures. Units shall be CSA listed, classified to  
ANSIZ21.47 standards, UL 1995/CAN/CSA No. 236-M90

GUIDE SPECIFICATIONS  
GENERAL  
Units shall be manufactured by Unitary Products in an ISO  
9001 certified facility.  
York's Sunline Ultra™ units are convertible single package  
units. All models have dual independent refrigerant circuits  
for efficient part load operation and maximum comfort con-  
trol. Although the units are primarily designed for curb  
mounting on a roof, they can also be slab-mounted at  
ground level or set on steel beams above a finished roof.  
Cooling only, cooling with gas heat and cooling with electric  
heat models are available with a wide variety of factory-  
mounted options and field-installed accessories to make  
them suitable for almost every application. All units are self-  
contained and assembled on full perimeter base rails with  
holes in the four corners for overhead rigging. Every unit is  
completely piped, wired, charged and tested at the factory  
to simplify the field installation and to provide years of  
dependable operation. All models (including those with an  
economizer) are suitable for either bottom or horizontal duct  
connections. Models with power exhaust are suitable for  
bottom duct connections only. For bottom duct, remove the  
sheet metal panels from the supply and return air openings  
through the base of the unit. For horizontal duct, replace the  
supply and return air panels on the rear of the unit with a  
side duct flange accessory. All supply air blowers are  
equipped with a belt drive that can be adjusted to meet the  
exact requirements of the job. A high static drive option is  
available for applications with a higher CFM and/or static  
pressure requirement.  
UNIT CABINET  
Unit cabinet shall be constructed of galvanized steel, with  
exterior surfaces coated with a non-chalking, powdered  
paint finish, certified at 1000 hour salt spray test per ASTM-  
B117 standards. Indoor blower section shall be insulated  
with a minimum 1/2" thick insulation, coated on the airside.  
Aluminum foil faced insulation shall be used in the furnace  
compartment and be fastened with ridged fasteners to pre-  
vent insulation from entering the air stream. Cabinet panels  
shall be "large" size, easily removable for servicing and  
maintenance. Full perimeter base rails shall be provided to  
assure reliable transit of equipment, overhead rigging and  
proper sealing on roof curb applications. Disposable 2" fil-  
ters shall be furnished and be accessible through a remov-  
able access door, sealed airtight. Units filter track shall be  
designed to accommodate either 2" or 4" filters. Fan perfor-  
mance measuring ports shall be provided on the outside of  
the cabinet to allow accurate air measurements of evapora-  
tor fan performance without removing panels or creating air  
by-pass of the coils. Condensate pan shall be internally  
sloped and conform to ASHRAE 62-89 self-draining stan-  
dards. Condensate connection shall be a minimum of 1" I.D.  
female and be a ridged mount connection. Unit shall incor-  
porate a fixed outdoor air damper with an outdoor air intake  
opening covered with a bird screen and a rain hood painted  
to match the exterior of the unit.  
Each unit shall have 2 condenser fan motors. All compres-  
sors include crankcase heat and internal pressure relief.  
Every refrigerant circuit includes an expansion valve, a liq-  
uid line filter-drier, a discharge line high pressure switch and  
a suction line with a freezestat and low pressure/loss of  
charge switch. The unit control circuit includes a 75 VA  
transformer, a 24-volt circuit breaker and a relay board with  
two compressor lockout circuits, a terminal strip for thermo-  
stat wiring, plus an additional set of pin connectors to sim-  
plify the interface of additional field controls. All models are  
CSA approved. All models include a 1-year limited warranty  
on the complete unit. Compressors and electric heater ele-  
ments carry an additional 4-year warranty. Aluminized steel  
tubular heat exchangers carry an additional 9-year warranty.  
INDOOR (EVAPORATOR) FAN ASSEMBLY  
Fan shall be a belt drive assembly and include an adjustable-  
pitch motor pulley. Job site selected (B.H.P.) brake horse-  
power shall not exceed the motors nameplate horsepower  
rating, plus the service factor. Units shall be designed not to  
operate above service factor. Fan wheel shall be double-inlet  
type with forward-curved blades, dynamically balanced to  
operate smoothly throughout the entire range of operation.  
Airflow design shall be constant air volume.  
DESCRIPTION  
A variable air volume (VAV) option using a variable frequency  
drive (VFD) is available for applications requiring a constant  
supply duct static pressure. Units equipped for VAV shall be  
controlled by a duct pressure transducer with a 0 - 5” WC pres-  
sure range. The pressure transducer shall provide a 0 - 5 VDC  
output signal to a VAV control board which, in turn shall provide  
a 2 - 10 VDC speed reference signal to the VFD. The VAV  
control board shall operate using factory-installed Supply  
Air, Return Air and Outside Air Temperature Sensors. Units  
equipped with VFD’s shall have factory-installed manual  
bypass as an option.  
Units shall be factory-assembled, single packaged, DH***N  
Electric Cooling/Gas Heat, DH***C/E Electric Cooling/
