Sizes 018 thru 060
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 Motor
provide 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.
