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

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

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.
• Further advice should be obtained from your pool or spa builder, accredited pool
shop, or chemical supplier for the correct levels for your water.
