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 1000 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.

Construction mode operation, 365-day real time clock with 7 day programming plus holiday scheduling is built-in. Two different modes of demand ventilation are achieved through the INTELLI-Com­fort™using CO2 sensors. It uses an inside CO2 sensor to perform Demand Ventilation. It can also use an Out­side CO2 sensor to perform Differential Demand Ventila­tion. It uses a Patented Comfort Ventilation algorithm to provide comfortable ventilation air temperature. The pat­ented economizer-loading algorithm will protect the equipment when harsh operating conditions exist. Humidity in the occupied space or return duct can be monitored and controlled via humidity sensors and the on-board connection for hot gas re-heat system. It uses the INTELLI-Start™ algorithm to maximize energy sav­ings by recovering the building from the Unoccupied Set­points to the Occupied Setpoints just in time for the Occupied Time Period to begin.

The rain hood is painted to match the basic unit and must be field assembled before installing.
ELECTRIC HEA T ERS wired for single point power sup­ply. 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.
HIGH ALTITUDE PROPANE - Burner orifices and pilot orifices are provided for proper furnace operation at alti­tudes up to 6,000 feet. This accessory supplements the basic propane conversion kit.
LOW NOX KIT- Required to reduce the emission of nitrogen oxides below 40 nanograms per joule.
POWER EXHAUST - Our single input 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 operation.
The power exhaust option can only be used on bot­tom duct configurations.
BAROMETRIC RELIEF DAMPER - This damper acces­sory 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.
ENTHALPY ACCESSORY CONTROL KIT - This kit contains the required components to convert a single enthalpy economizer to dual enthalpy.
BURGLAR BARS - Mount in the supply and return openings to prevent entry into the duct work.
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.

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.

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.
