RECOMMENDED WATER CHEMISTRY STANDARDS
While your heat pump’s titanium-based heat exchanger provides nearly impervious protection against
poor water chemistry, improper water chemistry may cause expensive damage to pump, filter, pool
shell, etc. To avoid equipment damage, maintain Pool-Spa water per standards below.
Failure to heed the following can result in damage to equipment.
CAUTION !
Improper water chemistry can present a serious health hazard. To avoid possible hazards, maintain
Pool-Spa water per standards below.
Failure to heed the following may result in permanent injury or
