Water Quality; Draining And Filling The Water Heating System; Maintenance And Regular Care; Servicing And Repair - Rinnai PRESTIGE Operation & Installation Manual

IMPORTANT INFORMATION & WARNINGS

WATER QUALITY

The water quality of most public supplies is suitable for the water heating system. The water quality from bore wells
is generally unsuitable for the water heating system. Refer to separate 'Warranty Terms and Conditions' document
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. The system is not suitable as a pool or spa
heater.

DRAINING AND FILLING THE WATER HEATING SYSTEM

•
Draining or filling normally occur only during installation or servicing and must be carried out by an
authorised person.

MAINTENANCE AND REGULAR CARE

Operate the easing gear of the PTR as described under "SAFETY DEVICES" on page 5.
The overflow tray (supplied by installer) and drain underneath the storage cylinder (if fitted) should be periodically
checked to ensure there are no blockages.

SERVICING AND REPAIR

Our Servicing network personnel are fully trained and equipped to give the best service on your appliance. If your
appliance needs service, ring one of the service contact numbers on the back of this booklet.
It is recommended that the system be serviced at least every 5 years.
The pressure and temperature relief valve and expansion control valve must be checked for performance or
replaced by an authorised person at intervals not exceeding 5 years or more frequently in areas where the water
is classified as scaling water (refer to 'Warranty Terms and Conditions' document - 'Water Quality').
It is recommended that the sacrificial anode fitted to Sunmaster cylinders be inspected very 5 years or more
frequently in areas where there is a high incidence of water deposits. This does not apply to Rinnai Prestige
cylinders. Anodes suited to hard and soft water, are available from Rinnai.
If the electric conduit, power supply cord or plug to the water heater is damaged, they must be replaced by an
authorised person in order to avoid a hazard. The power supply cord and plug (if fitted) must be replaced by a
genuine replacement part available from Rinnai.
