INTRODUCTION
The Heat Pump Water Heater System has been designed using the latest refrigeration
technology to remove the heat from the air to heat water. The refrigerant we use is R410a,
which does not contribute to global warming so it allows us to help keep a clean, healthy earth
for future generations. We have also considered the power requirement. By using R410a as
the refrigerant, we have produced one of the most energy efficient units currently available.
It's even more efficient when connected to off-peak power and the noise level is so low it will
operate unobtrusively throughout the night.
How it works
The Heat Pump Water Heater System heats water by transferring the heat from the
surrounding air to the water using a refrigerant. The refrigerant is heated by a heat
exchanger that absorbs heat from the surrounding air. (Figure1)
Figure 1: Heat Pump Water HeaterSystem
Note: Operating conditions may vary depending on the type of off-peak tariff that is available
in your area. The unit must have a minimum of 5 hours continuous power available at all time,
to allow the unit to operate without affecting reliability.

Removing air from the system
•The following steps must be taken to ensure all air is removed from the system.
Incorrect removal of air may cause the water temperature to vary.
•Plumb pipes to the tank unit and the heat pump unit.
•Push up the lever on the PTR valve to open, and fill the tank unit with water.
•Confirm that the water comes out of the relief valve and then close the lever.
•Open the hot water taps at home to remove air.
•Close the hot water taps at home after no air is confirmed in the water.
Figure 4: Air removing process
PTR valve lever
Plumb pipes to Storage Tank Unit and
Heat Pump Unit.
Push up the lever on the PTR valve to
open, and fill in the tank with water.
Confirm the water comes out of the relief
valve, and then close the lever.
Relief valve reading gear should be
operated AT LEAST ONCE EVERY SIX
MONTHS.
If water does not discharge freely when
the lever is operated, the valve should be
checked by an authorized agent.
Electrical connections
•Electrical installation should be done only by a licensed electrician who carries out
the work according to the relevant regulations for electrical safety and wiring.
•Follow the wiring rules for the breaker rating and the thickness of the electrical
wiring.
•Verify that the tank unit is full of water and the water stop cocks are open before
turning on the power.
System operation outline continuous power
•The system runs its water heating cycle once a day to fill up the storage tank unit
with heated water.
•If the block out time function is selected (setting is covered in Installation
Manual) the unit will not operate during the block out times - this function is typically
used on installations that have time of use electricitytariffs.
•The water heating cycle operation starts automatically when the residual hot water
in the tank unit becomes less than 45℃.
•The system will not run if the electrical power supply is cut off (i.e. if it is connected
to off-peak power). However, the system will automatically start operation, once
the electricity becomes available.
14 of 29

System operation if connected to off-peak electricity
•There are no special settings for the off-peak connection. The system will run once
the power becomes available and the temperature in the tank drops below the set
point of the tank thermistor. If connecting the unit to off-peak, ensure that the off-
peak tariff provides a minimum of 2 hours continuous power, as it can take at least 2
hours to fill the tank unit with hot water, if the ambient temperature is lower than 10,
this can be longer.
•If the unit is connected to off-peak and consumption has been higher than normal,
hot water might not be available until the next power supply cycle.
•Daily frequency and amount of hot water consumption may also affect the duration of
the heating cycle operation.
Select the electrical supply mode that best suits the customer's hot water
consumption. The type of off-peak connection may need to be changed
if hot water supply is not maintained as required.

Water supply Quality
Chloride and pH
In high chloride water supply areas, the water can corrode some parts and cause them to
fail. When the chloride level exceeds 200 mg/litre warranty does not apply to the heat pump
unit and tank unit. pH is a measure of whether the water is alkaline or acid. In an acidic water
supply, the water can attack the parts and cause them to fail. No warranty applies to the heat
pump unit and tank unit where the pH is less than 6.0. The water supply from a rainwater
tank unit in a metropolitan area is likely to be corrosive due to the dissolution of atmospheric
contaminants. Water with a pH less than 6.0 may be treated to raise the pH. It is
recommended that ananalysis of the water from a rainwater tank be conducted before
connecting this type of water supply to the system.
Figure 6:
Change of water supply
Changing or alternating from one water supply to another can have a detrimental effect on
the operation and/or life expectancy of the water tank unit cylinder, PTR valve, water
heating circulation and the heat exchanger in the system. When there is a changeover from
one water supply to another, for example, a rainwater tank supply, desalinated water
supply, public reticulated water supply or water brought in from another supply, then water
chemistry information should be sought from the supplier or the water should be tested to
ensure it meets the warranty requirements in this installationmanual.
Circulating Water Pump Flow
Changing or alternating from one water supply to another can have a detrimental effect
on flow rate in loop between heat pump and tank: 390L/h; actual measurement:
6.5L/min6.5*60=390L/h
Periodic Inspection
•It is recommended that a periodic inspection of the operating controls, heating elements
and wiring should be made by service personnel qualified in electric appliance repair.
Most electrical appliances, even when new, make some sound when in operation. If the
hissing or singing sound level increases excessively, please check the unit.
•Additionally, it is also recommended that the evaporator and refrigeration circuit are
checked every two years for dust and residues. In dusty environments it may be necessary
to have the appliance checked and cleaned on a more regular basis.

Checking the anode replacing if required
(Frequency: Every Half Year- Replace if required)
The anode protects the inner lining of your hot water tank. When the anode becomes
degraded the level of protection diminishes. It is recommended that the anode is periodically
checked for its level of degradation and gets replaced if required.
•Turn off the power, and turn off the cold-water inlet valve. Open a hot water tap, and
decrease the pressure of the inner container.
•Open the drain port, and release about 20 litres of water.
•Remove the top cover by removing the locking screw and rotating in a clockwise
direction the electrical compartment and put aside.
•Release the front casing, disconnect the disk.
•Locate the anode position on the left-hand side.
•Remove the anode cover by releasing the two screws.
•Unscrew the anode and lift directly up.
•Check for degradation.
•If still in suitable condition, refit ensuring an effective seal.
•If anode is in an unsuitable condition, replace with a new one, ensuring an effective
seal.
•Re-open the cold-water inlet valve.
•Open a hot water tap until hot water flows out, then turn off the hot water tap.
•Turn on the power to restart the unit.
•Now the unit can be used as normal.
