Refrigeration System - Multi-Circuit, Copper Tube Coil Extra large surface provides maximum cooling efficiency, excellent heat transfer and low air resistance

Precise circuiting gives uniform refrigerant distribution

Refrigeration System - Coil is constructed of precisely spaced ripple edged aluminum fins fitted to durable seamless, rifled copper tubes

Rifled tubing provides enhanced heat transfer which results in maximum coil performance when combined with fin design

Fins are strengthened to resist bending and are equipped with collars that grip tubing for maximum contact area

Flared tubing connections and silver soldering provide tight, leak-Proof joints

Long life copper tubing is corrosion-resistant and easy to field service

Coil is thoroughly factory tested under high pressure to ensure leak-Proof construction

Expansion Valve

Refrigerant Piping and Drain Connections - Refrigerant line inlets (knockouts) are provided on both sides of the cabinet

Refrigerant lines require sweat connections and are made internal to the cabinet

Condensate drain outlet extends outside the cabinet for ease of connection. Condensate drain can be relocated to other side of cabinet and can be repositioned for horizontal air flow applications

Control Box - Control box located in separate compartment in unit cabinet

Low voltage terminal strip factory installed

Blower contactor furnished and factory installed in control box

Cabinet - Cabinet is constructed of Heavy Gauge, pre-painted steel for superior rust and corrosion protection

Cabinet is completely lined with thick fiberglass insulation resulting in quiet and efficient operation

Closed-cell foam on top mullion between the blower and coil section reduces heat transfer through cabinet and prevents moisture build-up on outside of cabinet

Supply and return air duct flanges are furnished for field installation. See dimension drawings

Service access is provided on three sides of unit

Large removable panels provide complete service access on one side of unit

Electrical inlets are conveniently located in the cabinet

Drain Pan - Deep, corrosion resistant plastic drain pan

Reversible drain pan allows for drain outlets on either end of cabinet and can be repositioned for horizontal air flow applications

Drain pan is removable from either side in both horizontal and vertical applications

Blow-off baffle and extended drip shield collects condensate from the coil and directs it to the drain pan

Refrigerant - Units operate with chlorine-free, ozone friendly, R-410A

Outdoor Coil Fan - Direct drive fan(s) moves large volumes of air uniformly through entire condenser coil(s) for high refrigerant cooling capacity

Upward discharge of air reduces operating sound levels and prevents damage to lawns, shrubs and walkways

Fan motors are totally enclosed, overload protected and equipped with a rain shield

Fan service access is accomplished by removal of fan guard(s) or removal of access panel

Copper Tube/Enhanced Fin Coil - Units are equipped with a wrap-around "U" shaped coil (072-090-120 models) or two "L" shaped coils

Coils are constructed of precisely spaced ripple-edge aluminum fins machine fitted to seamless copper tubes

Lanced fins provide maximum exposure of fin surface to air stream resulting in excellent heat transfer

Fins equipped with collars that grip tubing for maximum contact area

Flared shoulder tubing connections and machine brazed silver soldering provide tight, leak-Proof joints

Long life copper tubing is corrosion-resistant and easy to field service

Thoroughly factory tested under high pressure to ensure leak-Proof construction

Completely accessible for cleaning

High Pressure Switch - Shuts off unit if abnormal operating conditions cause discharge pressure to rise above setting

Protects the compressor from excessive condensing pressure

Manual reset

Loss of Charge Switch - Shuts off unit if liquid line pressure falls below setting

Provides loss of charge and freeze-up protection

Automatic reset

Hi-Capacity Drier - Drier traps moisture or dirt that could contaminate the refrigerant system

Refrigerant Lines and Service Valves - Suction and liquid lines are located on corner of unit cabinet and are made with sweat connections

Fully serviceable suction and liquid line service valves provide complete service access to refrigerant system

Suction valve can be fully shut off, while liquid valve can be front seated to manage refrigerant charge while servicing system Accessible outside of unit cabinet

Compressor - Compressor 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

Crankcase Heater - Crankcase heater(s) prevents migration of liquid refrigerant into compressor(s) and ensures proper compressor lubrication

Cabinet - Heavy gauge, pre-painted steel cabinet provides superior rust and corrosion protection

Removable panels allow access for unit servicing

Heavy Duty steel base channels raise the unit off of mounting surface away from damaging moisture Unit lifting holes and forklift slots furnished in base rails
