• Proper chemical balances are necessary
for sanitary bathing conditions, as well
as ensuring your heater's long life.
• For spas, it is necessary to perform
water changes, in addition to chemical
treatment. Change the spa water every

days if usage is heavy.

warrant heat exchangers damaged by
corrosive chemical levels or excess
