York E2FB090 Information Manual

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 dehydrated, evacuated, leak tested and pressure tested
before being pressurized with a holding charge of
refrigerant-22 for shipment and/or storage. The compressor,
the fan motors and the controls are functionally tested after the
units are fabricated to assure a reliable 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
distributor 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
constructed of commercial grade (G90) galvanized steel. After
fabrication, 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 "desert sand" 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 servicing, 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
protection. 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 contactor and a small holding charge of refrigerant-22.
They also include a filter-drier, an expansion valve and a
distributor that are only used during the cooling cycle plus 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
installation. For horizontal installation, interchange the solid
bottom panel and the return air duct flange on the front of the
unit.
