FEATURES

All models are available with a wide variety of factory­mounted 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.
All units are self-contained and assembled on full perimeter base rails with forklift holes on three sides and holes 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. 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:
Single enthalpy economizer
Motorized outdoor air damper Supply air blowers are equipped with either a direct drive or a
belt drive that can be adjusted to meet the exact require­ments 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 compo­nents.

high and low-pressure switches, the freezestats, the 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.
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.
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 units have long lasting powder paint cabinets with 1 000 hour salt spray test approval under ASTM-B117 procedures.
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.
Gas Heat Operation - All single phase models with gas heat have minimum annual fuel utilizati on efficiency (AFUE) of 80%. All three phase models with gas heat have minimum steady state efficiency of 80%. 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 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 uni­form distribution of air across the heating elements. Every element is fully protected against excessive tem­perature by thermal limit switches.
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.

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.
Factory installed Smoke Detectors in the return air, may be subjected to freezing temperatures during “off” times due to outside air infiltration. These smoke detectors have an operational limit of 32°F to 131°F. Smoke detectors installed in areas that could be outside those limitations will have to be moved to prevent having false alarms.

FIELD-INSTALLED ACCESSORIES

SINGLE INPUT ELECTRONIC ENTHALPY ECONO­MIZERS - Includes a slide-in / plug-in damper assembly
with fully modulating spring-return motor actuator capa­ble of introducing up to 100% outdoor air with nominal 1% leakage type dampers.
The rainhood is painted to match the basic unit and must be field-assembled before installing.
MOTORIZED OUTDOOR AIR INTAKE DAMPER - Includes a slide-in / plug-in damper assembly with a 2­position, spring return motor actuator which opens to some pre-set position whenever the supply air blower is operating 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.
ELECTRIC HEATERS wired for single point power sup- ply. These nickel chromium heater elements are pro­vided with limit and automatic reset capability to prevent operation at excessive temperatures.
ROOF CURBS - Eight and 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.
Roof curbs are designed to fit inside the base rails of the unit and include both a wood nailing strip and duct hanger supports.
HIGH ALTITUDE NATURAL GAS - Burner orifices and pilot orifices are provided for proper furnace operation at altitudes up to 6,000 feet.
PROPANE - Burner orifices, pilot orifices and gas valve parts are provided to convert a natural gas furnace to propane.

1. These capacities are gross ratings. For net capacity, determine the kW of the supply air blower motor from the SUPPLY AIR BLOWER PERFORMANCE Table, 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 the SUPPLY AIR BLOWER PERFORMANCE Table for the kW of the supply air blower motor.
