FEATURES

Standard one-year warranty.

Five-year Extended Protection Plan for the compressor. Ten-year non-prorated warranty on heat exchanger.

Units are ``Rated in accordance with ARI Standard No. 270 and 210/240.''

Standard unit as factory assembled is design certi®ed and listed by UL and CSA.

Low temperature cooling operation standard to 40 F (4 C).

Hermetic compressor with internal linebreak and overload protection, self lubricating. Scroll compressors on 4 and 5 ton sizes.

Crankcase heater is standard on 024-042 3-phase units. (Not required on 018, 048 and 060 units.)

Indoor and outdoor coils constructed of aluminum ®ns mechanically bonded to seamless copper tubes.

48SS units have single-stage cooling and heating. Foil-faced cleanable insulation.

Sloped non-corrosive condensate drain pan.

Single-point gas connection.

Alternate electrical connections on opposite sides of unit.

Disconnect in accordance with NEC, must be ®eld-supplied and installed.

Multi-speed, direct drive indoor fan motor.

Weatherized cabinets. Heavy duty phosphated zinc-coated prepainted steel. Capable of withstanding 500-hour salt spray.

24-volt control circuit.

Heating controls include a direct spark ignition with ¯ame recti®cation. Fan switch, overtemperature switch, and ¯ame rollout switch also included.

Induced-draft with hall effect sensor (to prove proper inducer draft motor operation).

Alumaguard™ coated ``Super-S'' four-pass heat exchanger.

Integrated gas control board provides anti-cycle protection for gas heat operation.

Base rail standard on all 3-phase units.
