SAVE A SERVICE CALL

Check the items below before making a service call. You will be charged for attending to any condition or

fault that is not related to manufacture or failure of a part.

NOT ENOUGH HOT WATER (OR NO HOT WATER)

This can occur with new installations and is normally related to

some misunderstandings as to the use of the timer and gas booster.

Insufficient sunlight

Insufficient sunlight due to cloudy weather during hotter months

or low solar energy contribution in colder months may mean

you will need to activate the gas boosting more often (refer to

“Manual Boosting – Override Function” on page 16).

Pilot flame alight?

Check the pilot flame is burning by removing the access cover.

Relight the pilot flame according to the lighting instructions

(refer to “Lighting the Water Heater” on page 45).

Gas burner not operating

Inspect the isolating switch (adjacent to the water heater or at the switch board marked “HOT WATER”

or “WATER HEATER”) and ensure it is turned “ON”.

Note: Check the settings on the TIMER are sufficient to allow a full boosting cycle (refer to

“Recommended Timer On/Off Setting” on page 14).

Green LED is off or red LED is flashing on Solar Monitor

If the green LED is off or the red LED is flashing on the Solar Monitor label, there may be a problem with

the solar water heater operation and solar gain is not being achieved. This will result in the gas booster

operating to provide all of the hot water required.

Switch off the electrical supply at the isolating switch to the solar storage tank for a few seconds, then

switch on again.

If the green LED remains off or the red LED recommences to flash, then count the number of flashes

and phone Rheem Service or their nearest Accredited Service Agent to arrange for an inspection.

Collectors shaded

If trees or other objects shade the solar collectors or if the glass is dirty, the effectiveness of the solar

collectors will be greatly reduced. Have the trees trimmed or the solar collectors relocated if the

obstruction is permanent or clean the collector glass (refer to “Collector Glass” on page 12).

Collector area is too small

For most installations, the number of solar collectors recommended in Rheem literature has been

proven to provide the required solar energy to meet the average family needs. However, in some

circumstances, it may be necessary to install an additional solar collector.

Air in collectors (No solar gain)

It is possible under certain conditions, such as when the pipe work has been opened, that air may

become trapped in the solar collectors. This will prevent the circulator from moving water around the

collector circuit. The air will need to be purged from the solar collectors (refer to “Bleeding The Solar

Collectors” on page 9).

Are you using more hot water than you think?

Is one outlet (especially the shower) using more hot water than you think? Very often it is not realised

the amount of hot water used, particularly when showering. Carefully review the family‟s hot water

usage. As you have installed an energy saving appliance, energy saving should also be practised in the

home. Adjust your water usage pattern to take advantage of maximum solar gains. Have your plumber

fit a flow control valve to each shower outlet to reduce water usage.

Temperature pressure relief valve running

Is the relief valve discharging too much water? (Refer to “Temperature Pressure Relief Valve Running”

on page 21).
