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 66.

Monitor
The Great Big Bopper
®
heat pump comes with an ICM phase-rotation
monitor located inside the electrical panel.
The device protects the heat pump by preventing operation during
abnormal voltage conditions.
l
If the unit fails to operate, a qualified technician should check the
phase rotation monitor for faults preventing operation. Complete
instructions for the ICM phase monitor are in the appendix.
See " ICM
Digital 3-Phase Monitor " on page 69.
