Low Ambient - An integrated low-ambient control  
allows all units to operate in the cooling mode down  
to 0ºF 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.  
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.  
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.  
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.  
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 models are available with these “factory mounted” outdoor  
air damper options:  
Single enthalpy economizer with or without power  
exhaust  
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.  
BAS-ready economizer with or without power exhaust  
Motorized outdoor air damper  
Barometric Relief Damper  
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.  
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.  
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.  
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 vol-  
ume (VAV) option using a variable frequency drive is available  
for applications requiring a constant supply duct pressure. A  
differential 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.  
All units have long lasting powder paint cabinets with 1000  
hour salt spray test approval under ASTM-B117 procedures.  
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.  
All models are CSA approved.  
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.  
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  
S implicity® Controls - S implicity® control boards have  
standardized a number of features previously available  
only as options or by utilizing additional controls.

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  
available for single enthalpy and differential enthalpy  
configurations, respectively).  
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  
the front of the unit.  
BAS Controls - York’s Magnum series units offer factory  
mounted BAS controls such as York® S implicity® Intelli-  
Comfort, Novar, Honeywell, Johnson, and CPC.  
The rainhood is painted to match the basic unit and must  
be field-assembled before installing.  
POWER EXHAUST - Our single economizer options are  
available 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 opera-  
tion. 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

bracket, the maximum recommended drive dimensions  
are as follows:  
For 5-hp motor applications ........................13” H x 6” W x 7” D  
For 7.5 thru 15-hp motor applications.........13” H x 8” W x 8” D  
The exhaust fan, motor and controls are installed and  
wired at the factory. The rain hood must be assembled  
and installed in the field.  
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.  
The power exhaust option can only be used on bot-  
tom duct configurations.  
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.  
A terminal block located in the control box is provided for  
field connection of the VFD controls.  
The rain hood is painted to match the basic unit and  
must be field assembled before installing.  
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.  
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.  
FILTER OPTIONS - Standard units are shipped with 2”  
throw-away filters installed. 2” pleated and 4” pleated fil-  
ters are offered as a factory installed option.  
PHENOLIC COATED EVAPORATOR AND CON-  
DENSER COILS - Special coating process that utilizes  
Technicoat 10-1" processes. Coating is applied by total  
immersion of the complete coil for maximum protection.  
CONVENIENCE OUTLET - This 110 volt outlet can be  
“powered” by the unit with a stepdown transformer or  
you may order the unit with a “non-powered” conve-  
nience outlet that can be wired in the field.  
ELECTRIC HEATERS wired for single point power sup-  
ply. These nickel chromium heater elements are pro-  
vided with limit and automatic reset capability to prevent  
operation at excessive temperatures.  
DISCONNECT SWITCH - For gas heat units and cooling  
units with electric heat, a HACR breaker sized to the unit  
is provided. For cooling only units, a switch sized to the  
largest electric heat available for the particular unit is  
provided. Factory installed option only.  
VARIABLE AIR VOLUME (VAV) - A factory-installed  
variable frequency drive (VFD), mounted in the Blower  
Access compartment, is used to control the speed of the  
indoor blower motor in order to maintain a constant static  
pressure in the supply duct. A pressure transducer and  
VAV control board are mounted inside the control box.  
The drive comes completely wired and pre-programmed  
from the factory.  
DOUBLE WALL CONSTRUCTION - Optional double  
wall construction is available to provide smooth inner  
surfaces for easy and effective cleaning to reduce risk of  
dirt and bacterial accumulation. Fiberglass insulation is  
sandwiched between heavy gauge steel sheets to form a  
durable, rigid casing to withstand higher working pres-  
sures and impact forces. The heavy-duty construction  
provides excellent acoustic and thermal insulation and  
eliminates erosion of insulation material and contamina-  
tion of the air stream.  
An optional, factory-installed manual bypass switch  
available with factory-installed VFD can be found in the  
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.

These values have been accessed using a model of sound propagation from a point source into the hemispheric\free field. The  
dBA values provided are to be used for reference only. Calculation of dBA values cover matters of system design and the fan  
manufacture has no way of knowing the details of each system. This constitutes and expectation to any specification or guarantee  
requiring a dBA value or sound data in any other form than sound power level ratings.

For units with VFD and electric or gas heat, the  
speed of the indoor blower motor continues to  
be controlled by duct static pressure via the  
VAV control board.  
If there are VAV boxes present in the duct sys-  
tem, the boxes must be driven to the full-open  
position using a customer-supplied power  
source to assure adequate airflow across elec-  
tric heating elements or gas heat exchanger  
tubes.

The capacities are gross ratings. For net capacity, deduct air blower motor, MBh = 3.415 x kW. Refer to the appropriate Blower  
Performance table for the kW of the supply air blower motor.  
These ratings include the condenser fan motors (total 1 kW) and the compressor motors but not the supply air blower motor.

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

Deduct these resistance values from the available external static pressures shown in the respective Blower Performance Table (See Note 2 for  
exception.)  
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.

return damper actuator. The maximum leakage rate for  
the outdoor air intake dampers shall not exceed 2%  
when dampers are fully closed and operating against a  
pressure differential of 0.5 IWG. A unit-mounted potenti-  
ometer shall be provided to adjust the outdoor and return  
air damper assembly to take in CFM of outdoor air to  
meet the minimum ventilation requirement of the condi-  
tioned space during normal operation. During econo-  
mizer operation, a mixed-air temperature control shall  
modulate the outdoor and return air damper assembly to  
prevent the supply air temperature from dropping below  
55°F. Changeover from compressor to economizer oper-  
ation shall be provided by an integral electronic enthalpy  
control that feeds input into the basic module. The out-  
door intake opening shall be covered with a rain hood  
that matches the exterior of the unit. Water eliminator/fil-
