WATER QUALITY

NOTE: Failure to insure proper water quality
and flow rates can shorten the life of the
heat pump and potentially void the unit
warranty.
Maintaining proper water quality is important for
insuring a long and trouble free service life for an
SV series heat pump.

For closed loop and boiler/tower systems water
chemistry can be checked and easily maintained to
insure that corrosive elements, dissolved oxygen
and pH levels are kept in check. It is important to
insure that any additive, antifreeze or corrosion
inhibitor that is added to the water loop is
compliant with all applicable laws and regulations
and is compatible with copper, brass and bronze
alloys. Insure that all recommended safety
precautions are followed when handling or adding
chemicals to the water loop.
