Major Five (5) Year Service
It is recommended a major five (5) year service be conducted on the water
heater. Servicing must be performed by a qualified person. Phone
Aquamax Service or their nearest Accredited Service Agent.
Note: The five (5) year service and routine replacement of any
components, such as the relief valve(s), are not included in the Aquamax
warranty. A charge will be made for this work.
Major five (5) year service actions:
1. Replace pressure temperature relief valve.
2. Inspect and flush expansion control valve (if ECV fitted) and replace
expansion control valve if required.
3. Inspect anode and replace anode if required. If the anode is not
replaced, it should be replaced within three (3) years of this service.
Refer to ‘Anode’ on page 13.
4. Check and if necessary adjust burner gas pressure.
5. Check piezo igniter, gas control and thermocouple condition and
operation.
6. Check operation of and clean pilot and main burner.
7. Visually check the water heater for any potential problems.
8. Inspect all plumbing and gas connections.
Note: The water heater may need to be drained during this service and
may take up to an hour to reheat the water after servicing has been
completed.
Pressure Temperature Relief Valve (PTR valve)
The PTR valve is near the top of the water heater and is essential for safe
water heater operation. It is possible for the PTR valve to release a little
water through the drain line during each heating period. This occurs as the
water is heated and expands by approximately 1/50 of its volume.
Continuous leakage of water from the PTR valve and its
drain line may indicate a problem with the water heater
(refer to ‘Pressure Temperature Relief Valve Running’
on page 18).
Warning: Never block the outlet of the PTR valve
or its drain line for any reason.
Operate the easing lever on the PTR valve once every six months. It is
very important you raise and lower the lever gently.
