WATER CHEMISTRY
(Corrosive water voids all warranties)
For your health and the protection of your pool equipment, it is essential that your
water be chemically balanced. The following levels must be used as a guide for bal-
anced water.
Recommended Level(s) Fiberglass Pools Fiberglass Spas
Other Pool & Spa
Types
Water Temp. (Deg. F) 68 to 88 89 to 104 68 to 104
pH 7.3 to 7.4 7.3 to 7.4 7.6 to 7.8
Total Alkalinity (PPM) 120 to 150 120 to 150 80 to 120
Calcium Hardness (PPM) 200 to 300 150 to 200 200 to 400
Salt (PPM) 4500 MAXIMUM 4500 MAXIMUM 4500 MAXIMUM
Free Chlorine (PPM)* 2 to 3 2 to 3 2 to 3
Total Dissolved Solids (PPM) 3000 MAXIMUM** 3000 MAXIMUM** 3000 MAXIMUM**
* Free Chlorine MUST NOT EXCEED 5 PPM!
• Occasional chemical shock dosing of the pool or spa water should not damage the
heater providing the water is balanced.
• Automatic chemical dosing devices and salt chlorinators are usually more efficient
in heated water, unless controlled, they can lead to excessive chlorine level which
can damage your heater, and which is not covered under warranty. A check
valve should be installed between the heater outlet and a chlorinator or other chem-
ical dosing device.
• Further advice should be obtained from your pool or spa builder, accredited pool
shop, or chemical supplier for the correct levels for your water.
