Water Chemistry Levels Affecting Warranty
The Aquamax warranty of this water heater will not cover resultant faults on
components including the storage cylinder where water stored in the
storage cylinder exceeds at any time any of the following levels:
Total dissolved solids 600 mg/Litre
Total hardness 200 mg/Litre
Chloride 300 mg/Litre
Magnesium 10 mg/Litre
pH 9.5 and not less than 6.5
Calcium 20 mg/Litre
Sodium 150 mg/Litre
Iron 1 mg/Litre
Scaling Water
Scaling water is water that contains levels of calcium carbonate (total
hardness in excess of 200 mg/Litre at any time when the water heater is
operating). Scaling water can block and prevent the pressure &
temperature relief valve from operating resulting in damage to the water
heater storage cylinder and water heater components.
An ECV is mandatory in SA & WA and must be fitted in ALL areas with
scaling water to assist in preventing blockage of the pressure and
temperature relief valve.
Danger: Failure to install an expansion control valve where scaling
water conditions occur may result in the water heater storage cylinder
failing.
To avoid damage to the storage cylinder and water heater components,
Aquamax strongly recommend scaling water be treated before entering the
water heater by fitting appropriate water filters/conditioners etc. Refer to
your Local Water Authority for information on water in your area. A build up
of white sediment on hot water taps or shower roses can be indicative of
scaling water. Contact Aquamax if this condition is observed.
Note: Damage caused by scaling water can affect the Aquamax warranty.
(Refer to “Water Chemistry Levels Affecting Warranty” on page 13).
Spring, Dam, Bore & River Water Supplies
The Aquamax warranty of this water heater will not cover resultant faults on
components including the storage cylinder due to the effects of sludge
and/or sediment as a result of connection to a water supply from silted or
treated sources i.e. springs, dams, bores, rivers or towns supplied from a
bore.
