Direct--drive, PSC (Permanent Split Capacitor) condenser fan

motors are designed to help reduce energy consumption and

provide for cooling operation down to 55°F (12.7_C) outdoor

temperature. This unit is capable of low ambient cooling down to

0_F (--17.7_C) ONLY when using the Infinity control. A

low--ambient kit is not required, and the outdoor fan motor does

not need to be replaced for Infinity controlled low ambient

operation. Low ambient cooling must be enabled in the UI set--up.

Evolutionr User Interface is designed to work as a system with

Bryant’s single--packaged product.

Refrigerant system is designed to provide dependability. Liquid

refrigerant filter driers are used to promote clean, unrestricted

operation. Each unit leaves the factory with a full Puron refrigerant

charge. Refrigerant service connections make checking operating

pressures easier.

Thermostatic Expansion Valve—A hard--shutoff, balance port

TXV maintains a constant superheat at the evaporator exit (cooling

cycle) resulting in higher overall system efficiency.

High-- and Low--Pressure Switches give added safety and

reliability to the compressor.

Indoor and outdoor coils are computer designed for optimum

heat transfer and cooling efficiency. The indoor coil is fabricated

from copper tube and aluminum fins and is located inside the unit

for protection against damage. The outdoor coil is internally

mounted on the top tier of the unit. Copper fin coils and pre--coated

fin coils are available from the factory by special order. These coils

are recommended in applications where aluminum fins are likely to

be damaged due to corrosion. They are ideal for seacoast

applications.

Low sound ratings ensure a quiet indoor and outdoor

environment with sound ratings as low as 75 dBA.

Easy to service cabinets provide easy 3 panel accessibility to

serviceable components during maintenance and installation. The

basepan, with integrated drain pan, provides easy ground level

installation with a mounting pad. A nesting feature ensures a

positive basepan to roof curb seal when the unit is roof mounted. A

convenient 3/4--in. (19 mm) wide perimeter flange makes frame

mounting on a rooftop easy.

Evolution Furnace Control board provides safe and efficient

control of heating and simplifies trouble--shooting through its

built--in diagnostic function.

Heating

S Reliable direct spark ignition system

S Two--speed PSC inducer motor with ball bearings

S Low stage heating delivers 65% of high--stage capacity

Cabinets are constructed of heavy--duty, phosphated, zinc--coated,

pre--painted steel capable of withstanding 500 hrs of salt spray.

Interior surfaces of the evaporator and electric heater compartments

are insulated with foil--faced insulation, which keeps the

conditioned air from being affected by the outdoor ambient

temperature and provides improved indoor air quality. (Conforms

to American Society of Heating, Refrigeration and Air

Conditioning Engineers No. 62P.) The sloped drain pan minimizes

standing water in the unit, which is provided with an external

drain.

Louvered grille provides hail and vandalism protection for the

coil.
