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 controller or circulator has failed
Has the heat pump controller or circulator failed?
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 100 litres.
Refer to
“Heat Pump Is Not Operating”
on page 13.
Phone your nearest Rheem Service Department or Accredited Service Agent to arrange for an
inspection.
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?
The sizing guide in the sales literature and on the Rheem website
(www.rheem.com.au)
suggests
average sizes that may be needed.
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.
