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)
Is the electricity switched on?
Inspect the isolating switch marked “HOT WATER” or “WATER HEATER” at the switchboard and the
isolating switch (if one is installed) at the water heater and ensure they are turned on.
Check the fuse marked “HOT WATER” or “WATER HEATER” at the switchboard.
Is a timer installed?
If a timer has been installed, ensure sufficient time has been allowed to reheat the storage tank.
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
energy gains. Have your plumber install a flow control valve to
each shower outlet to reduce water usage.
Heat pump fault
Has the heat pump developed a fault?
The heat pump will not operate and the water heater will switch to
backup heating mode. The boost capacity of the heating unit in
backup heating mode is 110 litres.
Refer to
“Heat Pump Is Not Operating”
on page 13.
Temperature pressure relief valve running
Is the relief valve discharging too much water?
Refer to
“Temperature Pressure Relief Valve Running”
on page 14.
Water heater size
Do you have the correct size water heater for your requirements?
WATER NOT HOT ENOUGH
You may find that due to heavy hot water usage the water temperature may be lower than normally
expected, due to insufficient heating time being allowed. You will need to carefully plan your use of the hot
water on such occasions.
WATER TOO HOT
The water heater during heat pump operation and booster heating mode will heat the water to a temperature
of 60°C. If a heat pump component has developed a fault condition, the heat pump will not operate and the
water heater will switch to backup heating mode to ensure a supply of hot water.
In backup heating mode, the booster heating unit and its controlling thermostat will operate if heating of the
water is required, regardless of the ambient air temperature. The water heater, during backup heating mode
will heat the water to a temperature of 70°C. The boost capacity of the heating unit in backup heating mode
is 110 litres.
