POOL AND SPA WATER CHEMISTRY
NOTE: Chemical imbalance can cause severe damage to your heater and associated equipment. Maintain your water
pH between 7.4 and 7.8 and total alkalinity between 100 and 150 p.p.m. If the mineral content and dissolved solids in the
water become too high, scale forms inside the heat exchanger tubes, reducing heater efficiency and also damaging the
heater (max TDS at 3000 p.p.m.). If the pH drops below 7.2, the heater will be severely damaged.
NOTE: Heat exchanger damage resulting from chemical imbalance is not covered under the warranty.
