Specifications

Most importantly the electricity supply must be turned OFF.
Every 5 years you should contact the local service agent to replace all safety
valves and anodes to ensure continued system life and operational safety. In
locations where the potable water has a TDS greater than 600 ppm, this
service is recommended every 3 years.
SAFETY INFORMATION
For safe performance this water heater is fitted with:
• an over-temperature energy cut-out thermostat.
• a combination pressure & temperature relief valve.
These devices must not be tampered with or removed. The water heater must
not be operated unless both of these devices are fitted and in working order.
The element cover should only be removed by an electrician. The electrical
power supply switch must be turned off and the fuse removed at the main
electrical supply switchboard before the water heater electrical cover is
removed.
The pressure & temperature relief valve should be checked for adequate
performance or replaced at intervals not exceeding 5 years, or less in areas
where local regulations apply. The lever on the relief valve should be pulled to
operate the valve at least once every 6 months.
NOTE: The pressure & temperature relief valve and the drain outlet
pipe must not be sealed or blocked. It is normal for the valve to
overflow during heating cycles.
DANGER: Failure to operate the relief valve easing gear at least once
every six (6) months may mask a problem with the water heater.
