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 minimum operating flow rate is 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 (
37) is fully
open.
WATER FLOW FLUCTUATES
More than two or three hot taps in use at the same time may cause a decrease in the hot water flow from the
taps.
Is there more than two or three hot taps open, or are appliances such as a dishwasher or washing
machine, in use at the same time?
Ensure only two or three hot taps (or appliance) are on at the one time.
Check the flow of the water from one tap, e.g., the shower.
The shower should be adjusted so the hot tap is fully open.
