WATER CHEMISTRY
Chemical imbalance can cause severe damage to
your heater and associated equipment. Maintain your
water chemistry according to Table A. If the mineral
content and dissolved solids in the water become too
high, scale forms inside the heat exchanger tubes,
reducing heater efficiency and damaging the heater. If
the pH drops below 7.2, this will cause corrosion of the
heat exchanger and severely damage the heater. Heat
exchanger damage resulting from chemical imbalance
is not covered by the warranty.
For your health and the protection of your pool equip-
ment, 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 chlo-
rinators are usually more efficient in heated water,
unless controlled, they can lead to excessive chlo-
rine 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.
NOTE:
Corrosive water voids all warranties.
CAUTION:
Free chlorine must not exceed 5 ppm
which can damage the heater and void the warranty.
