2.
Operate easing lever on
expansion control valve (if ECV fitted) (refer to “Expansion Control Valve” on
page 8).
3.
If a safety tray is installed, check to ensure the safety tray drain pipe is not blocked.
4.
Clean solar collector gla
ss if required (refer to “Cleaning the Solar Collector Glass” on page 8).
Major Five Year Service
It is recommended a major five year service be conducted on the solar water heater including the gas
booster (for gas booster major five year service actions, r
efer to the Owner‟s Guide and Installation
Instructions supplied with the gas booster).
Servicing must be performed by a qualified person. Phone Aquamax Service or their nearest Accredited
Service Agent.
Note:
The five year service and routine replacement of any components, such as the anode and relief
valves, are not included in the Aquamax warranty. A charge will be made for this work.
Solar water heater major five year service actions:
1.
Replace pressure temperature relief valve.
2.
Inspect and flush expansion control valve (if fitted) and replace expansion control valve if required.
3.
Inspect and if required, replace the anode. If the anode is not replaced, it should be replaced within
three years of this service (
refer to “Anode” on page 8).
4.
Check the solar control unit for correct operation.
5.
Clean solar
collector glass if required (refer to “Cleaning the Solar Collector Glass” on page 8).
6.
Flush solar collectors (r
efer to “Flushing the Solar Collectors” on page 8).
7.
Visually check system for any potential problems.
8.
Inspect all plumbing and electrical connections.
9.
If a safety tray is installed, check to ensure the safety tray drain pipe is not blocked.
Note:
When switched back on, the solar water heater will take some time to reheat the water by solar gain.
The time to reheat the water in the solar storage cylinder will depend upon time of year, time of day and
prevailing weather conditions; however, the gas booster will provide hot water (or boost the temperature of
the delivered water) until the solar system hot water temperature is adequate.
Pressure Temperature Relief Valve (PTR Valve)
The PTR valve is near the top of the solar storage cylinder and is essential for safe 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 solar water heater (refer to
“Pressure Temperature Relief Valve Running” on
page 12).
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.
Warning:
Exercise care when operating easing leaver as water discharge from the solar water heater
may be of a very high temperature.
Warning:
Exercise care to avoid any splashing of water, as water discharged from the drain line will be
hot. Stand clear of the
drain line’s point of discharge when operating the valve’s lever.
Danger
:
Failure to perform this procedure may result in the solar storage cylinder failing, or under certain
circumstances, exploding.
If water does not flow freely from the drain line when the lever is lifted, then the solar water heater must be
checked. Phone Aquamax Service or their nearest Accredited Service Agent to arrange for an inspection.
The pressure temperature relief valve should be replaced at intervals not exceeding 5 years, or more
frequently in areas where there is a high incidence of water deposits (refer to
“Water Chemistry” on page 9).
