APPLICATIONSDesigned for outdoor installations at ground level or rooftop for residential applications.
Indoor and Outdoor CoilsCopper tube with aluminum fin coils.
Anti-Microbial Indoor Coil Drain PanAnti-Microbial additive resists growth of mold and mildew on drain pan which improves indoor
air quality and reduces drain line blockage.
Outdoor Coil FanWeather protected heavy duty outdoor coil fan motor with coated steel fan blades for long life.Internally mounted.Totally enclosed motor.Fan guard constructed of corrosion-resistant coated steel.
Reversing Valve4-way interchange reversing valve effects a rapid change in direction of refrigerant flow resulting in quick changeover from cooling to heating and vice versa.
High Pressure SwitchShuts off unit if abnormal operating conditions cause the discharge pressure to rise above setting.Protects compressor from excessive condensing pressure. Automatic reset.
Loss of Charge SwitchProvides loss of charge protection by shutting off unit if liquid pressure falls below setting.
Optional Accessories

SCROLL COMPRESSORCompressor features high efficiency with uniform suction flow, constant discharge flow and high volumetric efficiency and quiet operation.Compressor consists of two involute spiral scrolls matched together to generate a series of crescent shaped gas pockets between them.During compression, one scroll remains stationary while the other scroll orbits around it. Gas is drawn into the outer pocket, the pocket is sealed as the scroll rotates.As the spiral movement continues, gas pockets are pushed to the center of the scrolls. Volume between the pockets is simultaneously reduced.When pocket reaches the center, gas is now at high pressure and is forced out of a port located in the center of the fixed scrolls.During compression, several pockets are compressed simultaneously resulting in a smooth continuous compression cycle.Continuous flank contact, maintained by centrifugal force, minimizes gas leakage and maximizes efficiency.Scroll compressor is tolerant to the effects of slugging and contaminants. If this occurs, scrolls separate, allowing liquid or contaminants to to be worked toward the center and discharged.Low gas pulses during compression reduces operational sound levels.Compressor motor is internally protected from excessive current and temperature.Compressor is installed in the unit on resilient rubber mounts for vibration free operation.
Optional Accessories
Compressor Crankcase HeaterProtects against refrigerant migration that can occur during low ambient operation.
Compressor Hard Start KitSingle-phase units are equipped with a PSC compressor motor. This type of motor normally doesn’t need a potential relay and start capacitor.In conditions such as low voltage, this kit may be required to increase the compressor starting torque.
CABINETConditioned areas insulated with foil faced insulation to minimize heat loss and reduce operating sound levels.Powder paint for maximum durability.Easy service access.Steel louvered panels provides complete coil protection.
Airflow ChoiceUnits are shipped in horizontal configuration and can be field converted to downflow (vertical) airflow with optional Downflow Conversion Kit.
Electrical Inlets and Service ValvesField wiring inlets are located in one central area of the cabinet. See dimension drawing.Gauge ports are located inside the cabinet.
Optional Accessories
Downflow Conversion KitRequired for field conversion to downflow (vertical) air. Kit consists of 2 duct covers to block off horizontal air openings on side of unit. Required for field conversion to downflow (vertical) air. Kit consists of 2 duct covers to block off horizontal air openings on side of unit. Kit also includes drain pan overflow switch to monitor condensate level in drain pan, shuts down unit if drain becomes clogged.

Internal Filter Rack KitsAvailable for 1 in. thick filters. Kit contains filter rails for mounting filters internal to unit. Filters must be field provided. Filters are available separately.
FEATURES
ELECTRIC HEAT (5-20 KW)Field install internal to unit cabinet.Available in several voltages and kw sizes.Helix wound nichrome heating elements exposed directly in air stream resulting in instant heat transfer, low element temperatures and long service life.Cutoff limit control provides positive protection in case of excessive temperatures.Factory assembled with controls installed and wired.
Single Point Power KitsControl Box used with optional electric heat when singlepower supply is connected to multi-circuit electric heat.
CONTROLSElectronic blower control.Single pole contactor.Trade available components.
Defrost ControlDefrost control furnished as standard equipment.Gives a defrost cycle for every 30, 60 or 90 minutes (adjustable) of compressor “on” time at outdoor coil temperatures below freezing.Units are quiet-shift enabled. The compressor is de-energized entering and exiting the defrost cycle, reducing system sounds.Sensor mounted on liquid line determines when defrost cycle is required and also when to terminate cycle.Anti-short cycle, timed-off control incorporated into the board.
