Kelvinator heat pump hot water system
3. Once the heat pump has stopped and the tank is up to
temperature, drain some water off using a hot tap inside
and then operate the auxiliary boost button. Monitor
and confirm the operation of the tank element and
thermostat.
4. Once the hot water system is up to temperature, check
that hot water is available to all hot taps or fixtures in the
house and there is sufficient flow or pressure. Ensure that
any fixtures designed primarily for purposes of personal
hygiene do not have hot water above 50°C coming from
them and adjust the tempering valve as necessary.
5. Clean any filters that are installed in the water system of
the premises or at the individual fixtures as they may have
become blocked by debris during the installation and
commissioning of the hot water system.
Now that commissioning has been completed and the heat
pump hot water system has been set up to operate correctly,
select the correct model number of the storage tank on page
5 of the user manual. Fill out your details, the serial numbers,
installation date and any important notes for the customer.
The user manual is then to be handed to the customer or
left in a suitable location on the premises. If the customer is
available they should be instructed on the safe and correct
operation of the hot water system.
NOTE: If the heat pump hot water system needs to be
drained after commissioning please refer to the maintenance
section in the user manual supplied with the heat pump
for instructions.
Commissioning must only be commenced once the
installation has been completed according to the relevant
Australian standards and the instructions in this manual.
Confirm the following before operation:
• The heat pump has been installed correctly
• Air inlet and outlet of heat pump are free of obstacles
• Relief valve(s) installed correctly
• Drainage piping installed correctly
• Supplied tempering valve is installed correctly
• All water connections are correct
• Piping insulation has been installed
• Inlet valve is fully open
• Water is not leaking from the hot water system
• Air has been bled from the storage tank and
heat pump
• Temperature sensor installed correctly in
sensor pocket
• Electrical cables installed correctly
• Wiring configuration is correct
• Electrical testing has been completed and
satisfactory result obtained
• Power supply is either continuous or extended
off peak
The following steps are to be followed after the installation
of the heat pump hot water system to ensure its safety and
performance. If the hot water system cannot be setup to
perform correctly as specified in this manual, please call the
service centre for further instructions (number located in the
warranty section of this manual).
1. Turn on the power supply to the hot water system. If it has
been installed on an off peak power supply it may need
to be temporarily wired to a continuous power supply for
commissioning.
2. Allow the heat pump to run and monitor its operation
until the water in the storage tank reaches the set point
temperature and the heat pump shuts down. This may
take a few hours depending on the size of the storage
tank and the conditions at the time.
NOTE: If the heap pump does not begin operating after
a few minutes despite power being supplied to the heat
pump and the tank water being cold, the auxillary heating
boost button may have accidently been pressed during
commissioning or installation whilst the heat pump was
powered up. In this case, switch off the power supply
(both if connected to seperate continuous and off peak 2
power supply) for 2 minutes, then switch power back on
again to reset to normal heat pump operation. After a few
minutes the heat pump should start to operate.
To force the heat pump to operate, remove the lid on the
heat pump and carefully press and hold the two buttons
marked "force" and "query" on the printed circuit board.
The circulating pump should start and after one minute
the heat pump will begin to operate.
