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.

COLD WATER FROM THE HOT TAP

• Close the hot tap, wait 10 seconds and open the hot tap again.

• Is the hot tap open enough? The gas booster burners will not light if the flow rate is less than

3.0 L / min.

• Solar control unit and gas booster not operating

 Check the power supply cord is plugged in and the

power outlet switched on.

 Is power available in the house? Try using another

electrical appliance.

• Gas supply

 Is the isolation valve in the gas line open?

 Is there a gas supply to the rest of the house? Try

lighting another gas appliance.

 Has the gas line been purged of air after installation?

Refer to your plumber.

NO WATER FROM THE HOT TAP

No flow of water from the hot tap may indicate a restriction in or failure of the cold water supply to the

water heater. Check for water flow at other taps and that the cold water isolation valve (refer to

page 29) is fully open.

GAS BOOSTER OPERATING TOO FREQUENTLY

You may find that the gas booster operates more frequently than expected. This will occur when the

solar preheat water temperature is lower than 58°C, which may be experienced during periods of low

solar energy gain or if there has been heavy hot water usage. Factors to consider are:

• Insufficient sunlight

Insufficient sunlight due to cloudy weather during summer months or low solar energy contribution

in winter months may mean the gas booster operates more often.

• 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 Solahart 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.
