gas valve, if applicable, and the temperature limit  
switch on gas heat units. The unit control board will  
alarm on ignition failures, compressor lockouts and  
repeated limit switch trips.  
FEATURES  
All models are available with a wide variety of factory-  
mounted options such as stainless steel heat exchangers,  
electric heaters, phase monitor, convenience outlet, dirty filter  
switch, disconnect switch, smoke detectors, and coil guard to  
make them suitable for almost every application.  
Nuisance Trip Protection- To prevent nuisance  
trouble calls, the control board uses a “three strikes,  
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 compressor.  
All units are self-contained and assembled on full perimeter  
base rails with forklift holes on three sides and holes for over-  
head 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.  
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 models (including those with an economizer) are suitable for  
either bottom or horizontal duct connections. For bottom duct,  
remove the sheet metal panels from the supply and return air  
openings through the base of the unit. For horizontal duct,  
remove the supply and return air panels on the rear of the unit.  
All models are available with these “factory mounted” outdoor  
air damper options:  
All units have long lasting powder paint cabinets with 1000  
hour salt spray test approval under ASTM-B117 procedures.  
Single enthalpy economizer  
Motorized outdoor air damper  
All models are CSA listed.  
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.  
Supply air blowers are equipped with either direct drive or  
belt drive that can be adjusted to meet the exact require-  
ments of the job.  
All compressors are equipped with internal pressure relief.  
Every refrigerant circuit includes a liquid line filter-drier, a high  
pressure switch and a suction line with a freezestat and low  
pressure/loss of charge switch to protect all system compo-  
nents.  
Gas Heat Operation - All single phase models with gas  
heat have minimum annual fuel utilization efficiency  
(AFUE) of 80%. All three phase models with gas heat  
have minimum steady state efficiency of 80%. Each sec-  
tion 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.

®
S implicity Controls - S implicity control boards have  
standardized a number of features previously available  
only as options or by utilizing additional controls.  
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.  
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.  
Electric Heat Operation - All electric heat models 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 provide a high velocity and uni-  
form distribution of air across the heating elements.  
Every element is fully protected against excessive tem-  
perature by thermal limit switches.  
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.  
The power supply wiring can be routed into the control  
box through a threaded pipe connection (field supplied)  
in the base pan of the unit or through a knockout in the  
wiring panel on the side of the unit.  
Fan Delays - Fan on and fan off delays are fully pro-  
grammable and are independent of one another. All  
units are programmed with default values based  
upon their configuration of cooling and heat.  
Safety Monitoring - The control board monitors the  
high and low-pressure switches, the freezestats, the

1. These capacities are gross ratings. For net capacity, determine the kW of the supply air blower from the SUPPLY AIR BLOWER PERFORMANCE  
Tables, multiply this value by 3.415 MBH/kW to determine the motor heat, and deduct this heat from the gross capacity of the unit.  
2. These ratings include the compressor and the condenser fan motors but not the supply air blower motor. The total condenser fan motor  
power input is 0.36kW. Refer to SUPPLY AIR BLOWER PERFORMANCE Tables for the kW of the supply air blower motor.

1. These capacities are gross ratings. For net capacity, determine the kW of the supply air blower from the SUPPLY AIR BLOWER PERFORMANCE  
Tables, multiply this value by 3.415 MBH/kW to determine the motor heat, and deduct this heat from the gross capacity of the unit.  
2. These ratings include the compressor and the condenser fan motors but not the supply air blower motor. The total condenser fan motor  
power input is 0.36kW. Refer to SUPPLY AIR BLOWER PERFORMANCE Tables for the kW of the supply air blower motor.

1. Deduct these resistance values from the available external static pressure shown in SUPPLY AIR BLOWER PERFORMANCE Tables.  
2. Add these resistance values to the available static resistance values on SUPPLY AIR BLOWER PERFORMANCE Tables.  
3. The pressure through the economizer is greater for 100% outdoor air than for 100% return air. If the resistance of the return air  
duct system is less than 0.25 IWG, the unit will deliver less CFM during full economizer operation.
