SAFETY CONSIDERATIONS
Due to system pressure, moving parts and electrical
components, installation and servicing of air conditioning
equipment can be hazardous. Only qualified, trained, service
personnel should install, repair, maintain or service this
equipment.
Observe all precautions in the literature, on labels and tags
accompanying the equipment whenever working on air
conditioning equipment. Be sure to follow all other safety
precautions that apply.
Wear safety glasses and work gloves, and follow all safety
codes. Use a quenching cloth and have a fire extinguisher
available for all brazing operations.

GENERAL

YORK Model BCH 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
cooling/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 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.
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. Refer to Form 50.15-NM for additional information.
Installer should pay particular attention to the words: NOTE, CAUTION and WARNING. Notes are intended to clarify or make
the installation easier. Cautions are given to prevent equipment damage. Warnings are given to alert installer that personal injury
and/or equipment damage may result if installation procedure is not handled properly.

    FIG. 5 - TYPICAL FIELD WIRING The internal wiring harness furnished with this unit is an integral part of a ETL and CGA design certified unit. Field alteration to comply with electrical codes should not be required. A fused disconnect switch should be field provided for the unit. The switch must be separate from all other circuits.

    511.06-N3Y Refer to the Typical Field Wiring Figure and to the appropriate unit wiring diagram for control circuit and power wiring information. OPTIONAL ELECTRIC HEATERS The factory installed heaters are wired for single point power supply. Power supply need only be brought into the single point terminal block and thermostat wiring to the low voltage terminal strip located in the upper portion of the unit control box.

  • Page 15: Cooling System

    COOLING SYSTEM The unit has an air-cooled cooling section and is factory-charged with Refrigerant-22. The compressors are hermetically sealed, internally sprung and base-mounted with rubber-insulated hold-down bolts. Compressors have inherent (internal) protection. If there is an abnormal temperature rise in a compressor, the protector will open to shut down the compressor.
  • Page 16: Heat Anticipator Setpoints

    511.06-N3Y HEAT ANTICIPATOR SETPOINTS It is important that the anticipator setpoint be correct. Too high of a setting will result in longer heat cycles and a greater temperature swing in the conditioned space. Reducing the value below the correct setpoint will give shorter “ON” cycles and may result in the lowering of the temperture within the conditioned space.
  • Page 17: 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 will shorten the defrost initiation time periods above 35 F and will extend the defrost initiation time periods below 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.
