The AeroQuiet System (AQS) consists of 4 design features to achieve ultra-low sound ratings.
Aerocoustic Design featuring the Aeromax opening and wire dome top results in quieter and more efficient operation.
Energy-Efficient Fan and Fan Motorprovide a slower fan oper- ation, thus reducing noise and improving efficiency.
Sound Hood muffles noise from operation.
Discharge Muffler minimizes low frequency sound and pres- sure pulsation generated by compressor discharge gas.
The 697C Outdoor Sections of Split-System Heat Pumps are designed for quiet, reliable heating during the winter and cooling during the summer. These heat pump systems pro- vide economy of operation through energy conservation with SEER up to 14.0 and HSPF up to 9.0. They recover heat for indoor comfort from outdoor air during the heating season and, by automatically reversing the refrigerant system, re- move indoor heat and excess humidity during the cooling season. All models are listed with UL, c-UL, ARI, and CEC.
FEATURES
ELECTRICAL RANGE—All units are single phase 208/230v.
COMPRESSOR—This unit features a scroll compressor, which is significantly more efficient than conventional com- pressors. Its simple design offers improved reliability. Each compressor is mounted on rubber isolators for additional sound reduction. The scroll compressor starts under most system loads, thus eliminating the need for start assistance components. For improved serviceability, the 018 through 042 models are equipped with a compressor terminal plug. Continuous operation is approved down to –30°F (–34.4°C) in the heating mode and down to 55°F (12.8°C) in the cooling mode. (See heating and cooling performance tables.) The scroll compressor is covered with a standard 10-year limited warranty.
BUILT-IN-RELIABLE COMPONENTS—All units include a suc- tion tube accumulator that minimizes the amount of liquid re- frigerant that reaches the compressor; a high-pressure switch for high-pressure protection; and a low-pressure switch for loss of charge protection.
DEFROST CONTROL BOARD—Incorporates a built-in 5- minute compressor time-delay relay, defrost relay, defrost timer, and low-voltage terminal board. The defrost control is a time/temperature initiation/termination control, which includes 3 field-selectable time periods of 30, 50, and 90 minutes.
THERMOSTATIC EXPANSION VALVE (TXV)—This unit must be installed with a TXV on the indoor coil. The FC4 and FK4 indoor fan coils come factory equipped with a bi-flow TXV. When installed in this application, no further change is required. If any other indoor fan coil or furnace coil is used, an accessory bi-flow TXV must be installed. See accessory list in this publication for correct part no.
WEATHER-PROTECTIVE CABINET—Steel is galvanized and coated with a layer of zinc phosphate. A coat of modified polyester powder coating is then applied and baked-on, pro- viding each unit with a hard, smooth finish that will last for many years.
All screws on cabinet exterior are coated for a long-lasting, rust-resistant, quality appearance.
UNIT DESIGN—All units are equipped with totally enclosed fan motors for greater reliability under rain and snow condi- tions. The large, wraparound coil uses copper tube and en- hanced aluminum fin and is designed for optimum heat transfer during heating and cooling. The vertical air discharge carries the sound and air up and away from adjacent patio ar- eas and foliage. Rows of composite coils can be cleaned with a common garden hose.
EXTERNAL SERVICE VALVES—Both service valves are brass, back seating type with sweat connections. Each valve has a service port for ease of checking operating refrigerant pressures. The suction service port provides for ease of checking operating pressure in the heating mode.
LIMITED WARRANTY—Standard 1-year warranty on all parts, with an additional 9-year warranty on compressor.
