(Corrosive water causes damage that will not be covered under warranty.)
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!
• 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 levels, 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.

Titanium is immune to saline and seawater.
