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 balanced water.

*Free Chlorine MUST NOT EXCEED 5 PPM!
**CR Superalloy can tolerate higher salt levels, and is even seawater resistant, but salt levels above 6000 PPM may cause damage to other components of the pool system, pool equipment or hardware.
•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.
•Further advice should be obtained from your pool or spa builder, accredited pool shop, or chemical supplier for the correct levels for your water.
