Multi-Circuit, Copper Tube Coil-Extra large surface provides maximum cooling efficiency, excellent heat transfer and low air resistance, Coils on 090-240 models are face split with separate circuits, each circuit has its own expansion valve, Precise circuiting gives uniform refrigerant distribution, 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-For use with R-410A systems, Factory installed and piped, Multi-circuit coils are equipped with one thermal expansion valve per circuit, Valves are sized for best performance, 090 and 120 models have internal check valves for use with heat pump systems

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

External Filter Rack-Filter rack design permits quick and easy removal of filters for servicing, Heavy-gauge galvanized steel cabinet is completely insulated with thick, foil-faced fiberglass insulation and painted to match the unit, Furnished and shipped inside the unit for field installation, Must be field assembled, 2Inch thick, MERV 8 pleated media filters are furnished as standard

Belt Drive Blower-072-090-120-150 models are equipped with a single blower wheel, 180 and 240 models have dual blower wheels, Centrifugal belt driven blowers deliver large air volumes quietly and with low power consumption, Blower wheels are Heavy Duty, with forward curved blades and double inlet, Wheels are statically and dynamically balanced to eliminate vibration and designed to give maximum air delivery, Bearings are Heavy Duty, permanently sealed and lubricated, Belt tension is automatically controlled by auto tensioning device

Single Zone VAV Supply Fan VFD Kit-Variable frequency drive (VFD) and control stages the supply air blower airflow, Designed for use on dual-stage split systems the VFD alters the frequency and voltage of the power supply to control blower motor speed and airflow Supply air blower has two speeds

Control Box-Located in separate compartment in unit cabinet, Low voltage terminal strip factory installed, Blower contactor furnished and factory installed in control box, All controls are pre-wired at the factory

Cabinet -Heavy-gauge, pre-painted steel for superior rust and corrosion protection, 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, Service access 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
