DESCRIPTION
YORK has combined the latest concepts in modern technology
with time-proven quality standards to design a split-system heat
pump to meet the demands of the energy and quality-conscious
commercial market.
Both the outdoor and indoor units are completely piped and wired
at the factory. Only the interconnecting liquid and vapor lines are
required to complete the refrigerant circuit. Every unit is dehy-
drated, evacuated, leak tested and pressure tested before being
pressurized with a holding charge of Refrigerant-22 for shipment
and/or storage. The compressor, fan motors and controls are
functionally tested after the units are fabricated to assure a reli-
able start-up and years of dependable operation.
These units have been tested by Underwriters' Laboratories and
will be shipped with UL and CUL labels.
OUTDOOR UNIT
Every outdoor unit includes a heavy-duty compressor with a
crankcase heater, line break overload protection, a suction line
accumulator with a fusible plug, a 4-way reversing valve with a
24-volt solenoid, outdoor fan motor(s) with inherent protection,
and a copper tube/aluminum fin coil that is positioned vertically for
better drainage of the water that will condense on it during the
heating cycle.
They also include a filter-drier, an expansion valve and a distribu-
tor that are only used during the heating cycle plus a check valve
to provide the proper flow of refrigerant through the unit during
both the cooling and heating cycles.
To eliminate the costly cabinet deterioration problems usually
associated with outdoor equipment, all sheet metal parts are con-
structed of commercial grade (G90) galvanized steel. After fabri-
cation, each part is thoroughly cleaned to remove any grease or
dirt from its surfaces. The parts that will be exposed to the
weather are then coated with a powder paint to assure a quality
finish for many years. This coating system has passed the 750
hour, salt spray test per ASTM Standard B117. To assist in ser-
vicing, the high and low pressure service connections are exterior
to the cabinet, allowing simple access.
The fan guards are vinyl-coated to provide additional rust protec-
tion. An optional decorative coil guard is available to protect the
coil on the outdoor unit.
INDOOR UNIT
Every indoor unit includes a well-insulated cabinet, a copper tube/
aluminum fin coil, 1" throwaway filters, a centrifugal blower, a
blower motor, adjustable drive components, a blower motor con-
tactor and a small holding charge of Refrigerant-22.
They also include a filter-drier, an expansion valve and a distribu-
tor that are only used during the cooling cycle; also, a check valve
to provide the proper flow of refrigerant through the coil during
both the cooling and heating cycles.
The units are shipped in the vertical position ready for field instal-
lation. For horizontal installation, interchange the solid bottom
panel and the return air duct flange on the front of the unit.
