Part 2 Ð Products

2.01EQUIPMENT (STANDARD)

A.General:

The 579F unit shall be a factory assembled, single-piece heating and cooling unit. Contained within the unit enclo- sure shall be all factory wiring, piping, controls, refrigerant charge (R-22), and special features required prior to ®eld start-up.

B.Unit Cabinet:

1.Unit cabinet shall be constructed of galvanized steel, bonderized and coated with a prepainted baked enamel

®nish.

2.Indoor blower compartment interior surfaces shall be insulated with a minimum 1¤2-in. thick, 1 lb density neo- prene cooled, ®berglass insulation coated on the air side. Aluminum foil-faced ®berglass insulation shall be used in the gas heat compartment.

3.Cabinet panels shall be easily removable for servicing.

4.Filters shall be accessible through an access panel.

5.Holes shall be provided in the base rails for rigging shackles to facilitate overhead rigging.

6.Unit shall have a factory-installed internal condensate drain connection and a sloped condensate pan.

C.Fans:

1.Indoor blower (evaporator fan):

a.Fan shall be belt driven. Belt drive shall include an adjustable pulley. The standard fan drive shall have a factory-installed low-medium static pres- sure fan drive. The alternate fan drive option shall have a factory-installed high static pressure fan drive.

b.Fan wheel shall be made from steel with a corro- sion resistant ®nish. It shall be a dynamically bal- anced, double-inlet type with forward-curved blades.

2.Condenser fans shall be of the direct-driven propeller type, with corrosion-resistant blades riveted to corrosion-resistant steel supports. They shall be dy- namically balanced and discharge air upwards.

3.Induced-draft blower shall be of the direct-driven, single inlet, forward-curved, centrifugal type. It shall be made from steel with a corrosion-resistant ®nish and shall be dynamically balanced.

D.Compressor(s):

1.The reciprocating semi-hermetic compressor(s) has factory-installed external spring vibration isolation.

2.Factory-installed crankcase heater prevents refriger- ant dilution of oil.

3.The 180 size semi-hermetic compressor shall be equipped with an electric unloader for capacity con- trol. Additional ®eld-supplied unloaders are not recom- mended on any 180-300 sizes.

4.Compressors shall be on mechanically and electrically independent circuits (216-300 sizes).

E.Coils:

1.Standard evaporator and condenser coils shall have copper or aluminum plate ®ns mechanically bonded to seamless internally grooved copper tubes with all joints brazed.

2.Optional precoated coils shall be coated with a baked-on organic, epoxy, phenolic coating.

F.Heating Section:

1.Induced-draft combustion type with energy saving direct-spark ignition system and redundant main gas valve.

2.The heat exchanger shall be of the tubular-section type constructed of a minimum of 20-gage steel coated with a nominal 1.2 mil aluminum-silicone alloy for corrosion resistance.

3.Burners shall be of the in-shot type constructed of aluminum-coated steel.

4.All gas piping shall enter the unit at a single location.

G.Refrigerant Components:

Refrigerant circuit components shall include:

1.Fixed expansion device with ®lter driers.

2.Service valve gage and connections on suction, dis- charge, and liquid lines.

3.Thermostatic expansion valve (size 180) or ®xed ori- ®ce feed system (sizes 216-300).
