Water Quality Standards

Clean water is essential to the performance and life span of water source heat pumps. Contaminants, chemicals, and
minerals all have the potential to cause damage to the water heat heat exchanger if not treated properly. All closed
water loop systems should undergo water quality testing and be maintained to the water quality standards listed in
this table.

Do not connect heat pump to steel pipe unless dissimilar materials are separated by using Di-electric unions. Galvanic corrosion of heat
pump water pipe will occur.
