REQUIREMENTS:
50° Minimum Entering Water Temperature
Cupronickel Refrigerant Heat Exchanger
When a water well is used exclusively for supplying water to the heat pump, a cupronickel refrigerant heat exchanger is
required and the well pump should operate only when the heat pump operate. A 24 Volt contactor can be wired to the ACC1
terminal on the Control Module which can be selected to be energize prior to or at compressor start-up, which would in turn
energize the water pump to operate with the heat pump.

Table 6 – Well Water Application Data
Minimum entering water temperature is 50°F. Failure to
follow this warning could result in equipment failure
and property damage.
The discharge water from the heat pump is not
contaminated in any manner and can be disposed of in
various way depending upon local codes.
Close loop and pond applications require specialized
design knowledge. Do not attempt at these installations
without the licensed installer the received specialized
training.
