Specifications

• Do you have the correct size water heater for your requirements? Sizing
details are available from your Dux supplier.
• Is one outlet (such as the shower) using more hot water than you think?
• Carefully review the family's hot water usage and if necessary check the
shower flow rates with a bucket, measuring the amount of water used over
that period of time. If it is not possible to adjust water usage patterns, an
inexpensive flow control valve can easily be fitted to the shower outlet.
• Consider that during night time heating, the time taken to heat the tank can
take longer (less energy in the air) so you may find that the tank has not
fully recovered from a period of heavy usage the previous evening.
• Consider that often the hot water usage of showers, washing machines
and dishwashers can be under estimated. Review these appliances to
determine if your daily usage is greater than the storage volume of your
water heater. If for example you have a 315 litre storage tank and you are
using 450 litres of water it is possible that there will be certain times of the
day where there is insufficient hot water. It is also advisable to inspect tap
washers etc. for leakage and replace if necessary.
High Electricity Bills
• Is the Pressure & Temperature relief valve discharging too much water?
• Is one outlet (such as the shower) using more hot water than you think?
• Is there a leaking hot water pipe or dripping hot water tap? A small leak
can waste a large quantity of hot water.
• Replace faulty tap washers and have your plumber rectify any leaking pipe
work.
Condensation is dripping from inside the Airoheat
Check that the discharge location of the condensate drain has not been
blocked thereby restricting the condensation flow away from the heat pump.
The Airoheat does not Run
Check that the power supply is turned on and that the house circuit breakers
or Fuses are on and operational.
SYSTEM MAINTENANCE
The Heat Pump water heater is designed to eliminate system maintenance
other than that detailed in this owners manual.
Personally inspecting or servicing any part of the system is not recommended.
Should you decide to personally inspect the system, it is essential that you
observe all normal safety practices.
