ELECTRICAL ADJUSTMENTS
This series of electric cooling and, heat pump package equipment is de-
signed to accept a field installed electric heat kit. The unit is equipped to
easily install the HKP or HKR Series single phase and HKR3 Series 208-230
volt three phase Electric Heat Kits. Full Installation Instructions are in-
cluded in this kit. Please use this document for guidance in field equip-
ping the package unit with electric heat.
Choose the heat kit that fits the application for the specific installation.
Permanently mark the unit’s nameplate with the model being installed.
High and low voltage connections are detailed in the heat kit instruc-
tions.
Indoor Blower motor speed tap selection may need to be modified to
accommodate normal continuous operation to prevent a nuisance trip.
See following table.
REFRIGERANT CHARGE CHECKS
After completing airflow measurements and adjustments, the unit’s re-
frigerant charge must be checked. All package units are charged to the
superheat method at the compressor suction line (for fixed orifice de-
vices). After superheat is adjusted it is recommended to check unit sub-
cooling at the condenser coil liquid line out. For charge adjustments, see
superheat and subcooling charts shown for each model.
SUPERHEAT CAN BE DETERMINED AS FOLLOWS:
1. Read suction pressure. Determine Saturated Suction
Temperature from tables or pressure gauge saturated
temperature scale (R-410A).
2. Read suction line temperature.
3. Use the following formula:
SUPERHEAT = SUCTION LINE TEMP - SAT. SUCTION TEMP
