INSTALLATION INSTRUCTION
GENERAL
YORK Model B*CH units are single package heat pumps
designed for outdoor installation on a rooftop or a slab. These
units can be equipped with factory installed electric heaters for
supplemental heating applications.
The units are completely assembled on rigid, permanently
attached base rails. All piping, refrigerant charge, and electrical
wiring is factory installed and tested. The units require only
electric power, duct connections and installation of fixed
outdoor air intake damper (units without economizer or
motorized damper option only) at the point of installation.
These units are designed and manufactured under ISO 9002
Quality System Certification
The supplemental electric heaters have nickel-chrome
elements and utilize single point power connection.
INSPECTION
As soon as a unit is received, it should be inspected for possible
damage during transit. If damage is evident, the extent of the
damage should be noted on the carrier's freight bill. A separate
request for inspection by the carrier's agent should be made in
writing. See Local Distributor for additional information.

CAUTION: If a unit is to be installed on a roof curb or spe- cial frame other than a YORK roof curb, gasket- ing must be applied to all surfaces that come in contact with the unit underside. -
Page 4: Fixed Outdoor Air Intake Damper
FIXED OUTDOOR AIR INTAKE DAMPER This damper assembly is shipped inside the return air compartment. It is completely assembled and ready for installation. A damper baffle inside the hood is adjustable to provide variable amounts of outdoor air intake on units that are not provided with an economizer or motorized damper option. -
Page 5: Power And Control Wiring
035-18895-000-A-0902 POWER WIRING FIG. 5 - TYPICAL FIELD WIRING insulated wires 1.0mm (#18 AWG) should be used to connect thermostat to unit. Eight conductors are required. The subbase on the low voltage thermostat includes an “Emergency Heat ” position on the system switch and a pilot light. -
Page 6: Optional Econ./Motorized Damper Rain Hood
These heaters are located within the central compartment of the unit with the heater elements extending into the supply air chamber. Refer to Figure 7 for access panel location. Fuses are supplied, where required, by the factory. Some KW sizes require fuses and others do not. Refer to Table 2 for minimum air flow limitations and to Table 8 for electrical data. -

(See Note 2 for exception). Since the resistance to air flow will be less for sideflow duct connections than for downflow duct connections, add these pressures to the ESP values listed on the respective blower performance table. -
Page 12: Cooling System
COOLING SYSTEM The cooling section is a complete factory package utilizing an air-cooled condenser. The system is factory-charged with Refrigerant-22. The compressors are hermetically sealed, internally sprung and base-mounted with rubber-insulated hold-down bolts. The compressors also have inherent (internal) protection. If there is an abnormal temperature rise in a compressor, the protector opens to shut down the compressor. -
Page 13: Heat Anticipator Setpoint
035-18895-000-A-0902 HEAT ANTICIPATOR SETPOINT It is important that the anticipator setpoint be correct. Too high a setting results in longer heat cycles and a greater temperature swing in the conditioned space. Reducing the value below the correct setpoint causes shorter “ON” cycles and may result in the lowering of the temperature within the conditioned space. -
Page 14: Defrost Sequence Of Operation
DEFROST SEQUENCE OF OPERATION These heat pumps have a unique “ambient modified” time- temperature defrost control that automatically adjusts to changes in the outdoor temperature. The defrost control shortens the defrost initiation time periods above 2°C (35°F) and extends the defrost initiation time periods below 2°C (35°F. The control is factory set to defrost at 110 minutes (T3), but it can be field adjusted to defrost at 80 minutes (T2) or 50 minutes (T1) in areas with high humidity. -
