Surge Suppression
The use of approved commercial surge protectors is strongly recommended.
Sizing the Electrical Service
Refer to equipment data plate for specific information required to size electrical service and over-current
protection of the heat pump. Sizing is based on data plate information, wire size, wiring devices, and over-
current protection per applicable local codes and standards. See "
Identifying Model Specifications " on
page 74.
Minimum and Maximum Operating Voltage
The heat pump must operate within specified voltages.
NOTICE
Failure to heed the following may result in damage to equipment.
l
Operating equipment under higher or lower voltage conditions may result in damage to your compressor, motors
or other electrical components. This damage will not be covered by the product warranty.
1. Measure site voltage. The site voltage
MUST be measured under “FULL LOAD” conditions. Activate all
equipment using the same electrical panel as the heat pump.
2. If measured site voltage is outside listed ranges, immediately deactivate equipment until site conditions have been
corrected. If unsure of heat pump equipment rating, please see " Identifying Model Specifications " on page 74.
