Save A Service Call - Solahart 325 HAV Owner's Manual

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 and the red LED is flashing?
The heat pump will not operate and the water heater will switch to
backup heating mode using the booster heating unit.
"Heat Pump Is Not Operating"
Refer to
Temperature pressure relief valve running
Is the relief valve discharging too much water?
"Temperature Pressure Relief Valve Running"
Refer to
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 will heat the water to a temperature of 60°C. In booster heating
mode or back up heating mode the water will be heated to 70°C. The heat pump will operate when the
ambient air temperature is between a minimum of 3°C to 5°C and maximum of 45°C to 55°C. The booster
heating unit will operate in booster heating mode when the ambient air temperature is outside of this
temperature range, if heating is required. This is normal operation.
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 will operate if heating of the water is required, regardless of the ambient air temperature.
The red LED will flash to indicate the fault mode that has occurred. Refer to
page 15.
