APPLICATION CONSIDERATIONS

Well Water Systems

Copper is adequate for ground water that is not
high in mineral content. Should your well driller
express concern regarding the quality of the well
water available or should any known hazards exist
in your area, we recommend proper testing to
assure the well water quality is suitable for use
with water source equipment. In conditions
anticipating moderate scale formation or in
brackish water a cupro-nickel heat exchanger is
recommended. In well water applications water

pressure must always be maintained in the heat
exchanger. This can be accomplished with either
control valve or a bladder type expansion tank.
When using a single water well to supply both
domestic water and the heat pump care must be
taken to insure that the well can provide sufficient
flow for both. In well water applications a slow
closing solenoid valve must be used to prevent
water hammer. Solenoid valves should be
connected across Y1 and C1 on the interface board
for all. Make sure that the VA draw of the valve
does not exceed the contact rating of the
thermostat. (Figure #12)
