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.

•
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.

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.
