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)
