Water Quality

The water quality of most public supplies is suitable for the hot water system. The water quality from
bore wells is generally unsuitable for the hot water system. Refer to the 'Warranty Conditions' for water
quality parameters and how they affect the warranty conditions. If in doubt about the water quality,
have it checked against the parameters listed in the warranty conditions.
If sludge or foreign matter is present in the water supply, a suitable strainer filter should be
incorporated in the water supply to the system.

Regular Care

Over flow tray and drain.
The overflow tray and drain (if fitted) should be periodically checked to ensure there are no blockages.

Pressure and Temperature Relief (PTR) valve

This valve is located near the top of the water heater and is essential for
safe operation. It is normal for the valve to release a small quantity of
water through the drain line during heating.
However, continuous leakage of water from the valve and its drain line
may indicate a problem with the water heater.
Never block the outlet of the PTR valve or it's drain line for any reason. The easing gear
must be operated at least every 6 months to remove lime deposits and verify that it is

not blocked. Failure to do this may result in the water heater failing.
If the valve does not discharge water when the easing gear lever is opened, or does
not seal again when the easing gear is closed, attendance by an authorised person
must be arranged without delay.
The PTR valve is not serviceable.
