amount of field labor. A field supplied and field installed

electrical disconnect switch must be installed.

• Round Duct Flanges - (Factory Supplied - Field

Installed) Equal size, side supply and return duct flanges

allow easy hook-up of ducts.

• Condensate Pan - A non-corrosive, long-lasting, water-

tight pan is positioned below the evaporator coil to collect

and drain all condensate. Less collection of stagnate

condensate will build-up. The condensate pan conforms

to ASHRAE 62-89 standards (Ventilation for Acceptable

Indoor Air Quality).

• Condensate Drain - The 3/4 inch NPTF connection is

rigidly mounted to assure proper fit and leak tight seal.

• Durable Finish - With a heavy duty cabinet made of

powder-painted, galvanized steel the neutral color blends

into surrounding areas. The powdered paint provides a

better paint to steel bond, which resists corrosion and rust

creep. The glossy finish insures less fading when exposed

to sunlight and offers a more attractive on site

appearance. This paint finish meets ASTM-B117

standards for 1000 hours salt spray rating, the highest in

the industry.

• Full Perimeter Base Rails - The base rails provide a

solid foundation for the entire unit and protects the unit

during shipment. The rails provide fork lift access from all

sides. On applications where the unit is placed on a pad,

the base will keep the unit off the pad to deter corrosion.

• More Attractive Appearance - A single piece Water

Shed top cover containing a top discharge condenser fan

arrangement requires less square footage on installation

and provides a wider variety of installations. The one

piece design adds greater water integrity.

• Top Discharge - The top discharge condenser fan does

not disrupt neighboring areas or dry-out vegetation

surrounding the unit. The warm air from the top mounted

fan is blown up away from the structure and any

landscaping. This allows compact location on multi-unit

applications.

• Condenser Coil Grille - All models utilize a decorative

"Wire Form" coil guard to provide impact protection

against large objects.

• Low Operating Sound Level - The upward air flow

carries the normal operating noise up and away from the

living area. The rigid top panel effectively isolates any

motor sound. Isolator mounted compressor and the

rippled fins of the condenser coil muffle the normal fan

motor and compressor operating sounds.

• Fan System - 2, 2-1/2 and 3 Ton A/C models operate with

a 3-speed PSC (Permanent Split Capacitor) fan motor. 4

and 5 Ton A/C and all Heat Pump models operate with a

constant torque (X Motor) fan motor with 5 speed taps. All

these units easily match all types of applications and

provide greater on site flexibility to match comfort

requirements.

• Protected Compressor - The compressor is internally

protected against high pressure and temperature. This is

accomplished by the simultaneous operation of high

pressure relief valve and a temperature sensor which protect

the compressor if undesirable operating conditions occur.

• Pressure Switches - High pressure and low pressure/

loss of charge switches standard in all units. On Heat

Pump models, when abnormal conditions are sensed

through the pressure switches, the unit will lock-out

preventing further operation until reset or the problem is

corrected.

• Exclusive Coil Design - Grooved copper tubes and

enhanced aluminum fin construction on all indoor coils

and heat pump outdoor coils improve heat transfer for

maximum efficiency and durability or Micro-Channel

aluminum tube, aluminum fin on all cooling outdoor coils

for long lasting durability and efficient operation.

• Low Maintenance - Long life, permanently lubricated

condenser and evaporator fan motor bearings need no

annual maintenance adding greater reliability to the unit.

• Secured Service Access Ports - Protected, externally

mounted, re-usable service access ports are provided on

both the high and low lines for ease of evacuating and

charging the system. No final field mounting required.

• Easy Service Access - A large, single panel covers the

electrical controls makes servicing easy. The blower

compartment has a large panel which when removed will

allow the blower fan assembly to slide-out for ease of

maintenance and trouble shooting.

• Replacement Parts - The installer requires no special

training to replace any of the components of these units

and does not need to maintain an inventory of unique

parts.
