Page 4: Installation
INSTALLATION INSTALLATION STANDARDS The water heater must be installed: by a qualified person, and in accordance with the installation instructions, and in compliance with Standards AS/NZS 3500.4, AS/NZS 3000 and all local codes and regulatory authority requirements. In New Zealand, the installation must also conform with Clause G12 of the New Zealand Building Code. - Page 5 INSTALLATION Do not tilt the heat pump module or the heat pump and storage tank assembly more than 45° from the vertical. This will unsettle the refrigerant gas and compressor lubricating oil. If the heat pump module or heat pump and storage tank assembly has been tilted more than 45°...
- Page 6 INSTALLATION FREEZE PROTECTION The water heater has a freeze protection system. The freeze protection system will protect the water heater from damage, by preventing ice forming in the waterways of the water heater, in the event of freezing conditions occurring. If the water temperature at the heat pump heat exchanger falls below 3°C and the heat pump is not operating, the system will operate the circulator periodically.
- Page 7 INSTALLATION PURGING AIR FROM THE SYSTEM The water heater system must be purged of air prior to operation, using the air bleed valve supplied on the heat pump module. Failure to bleed the air out of the pipe work within the heat pump module will result in non-operation of the circulator and failure of the heat pump to operate due to overheating.

Page 9: Heat Pump And Tank Assembly
HEAT PUMP AND TANK ASSEMBLY STORAGE TANK AND HEAT PUMP MODULE The heat pump water heater is made of two main components, the storage tank and the heat pump module. For transport and handling (weight) purposes both items are shipped separately and designed to be assembled at the installation site. - Page 10 HEAT PUMP AND TANK ASSEMBLY heat pump module storage tank heat pump water heater...
- Page 11 HEAT PUMP AND TANK ASSEMBLY ASSEMBLY PROCEDURE Warning: The heat pump must be assembled, plumbed and filled with water prior to power being connected and switched on. The following procedure should be followed to properly lift, place and connect the heat pump module onto the storage tank: Storage Tank: Remove all packaging including the carton base from the storage tank and position in its intended location, supported by a stable base.
- Page 12 HEAT PUMP AND TANK ASSEMBLY Heat Pump Module: Place the heat pump module in front of the storage tank and open the top flaps of the carton. Two (2) lifting bars are housed in a recess in the cardboard layer on top of the heat pump module.
- Page 13 HEAT PUMP AND TANK ASSEMBLY Lifting Bars: Insert the two (2) lifting bars into the slots at the front of the heat pump module chassis and carefully push through to engage the slots at the rear. Take care not to catch any of the wiring or hoses in the heat pump module.
- Page 14 HEAT PUMP AND TANK ASSEMBLY Heat Pump Module Placement: Using two people, one person on each lifting bar, lift the heat pump module and place it on the top of the storage tank. It is recommended to place the hands under the bar to enable the lift in a curl action.
- Page 15 HEAT PUMP AND TANK ASSEMBLY Heat Pump Module Attachment: Remove the two (2) lifting bars and attach the heat pump module to the storage tank with the three (3) M6 screws provided with the heat pump module. screw holes (x3) nutserts (x3) inlet...
- Page 16 HEAT PUMP AND TANK ASSEMBLY Inlet Flexible Braided Hose: Attach the flexible braided hose marked “INLET” to the water fitting marked “INLET”. Tighten the swivel nut on the hose using a 24 mm spanner. Push down the pipe seal ring to seat over the swivel nut and against ...
- Page 17 HEAT PUMP AND TANK ASSEMBLY 11. Air Bleed Valve: Open the air bleed valve screw by rotating anticlockwise one turn. This will allow air to bleed from the circulator and flexible hose during the filling of the tank process. Leave the air bleed valve screw in this position. ...
- Page 18 HEAT PUMP AND TANK ASSEMBLY 12. Tank Sensor Cable Connection: Insert ONE tank sensor cable plug firmly into the connector marked “TANK SENSOR” at the bottom of the control board. Note: There are two tank sensor cables protruding through the top of the storage tank, each with a tank sensor cable plug.
- Page 19 HEAT PUMP AND TANK ASSEMBLY 13. Power Cable Connection: Connect the four (4) pin power cable plug to the connector at the top of the control board. Ensure the plug fully engages the locking feature on the connector. 14. Cable Tie Power Cable: Position the power cable firmly against the outside lower left hand side of the control board chassis and cable tie in position.

Page 22: Commissioning
COMMISSIONING TO FILL AND TURN ON THE WATER HEATER The power supply to the water heater must not be switched on until the water heater is filled with water and a satisfactory megger reading is obtained. Open all of the hot water taps in the house (don‟t forget the shower). Open the cold water isolation valve fully to the water heater. - Page 23 COMMISSIONING TO TURN OFF THE WATER HEATER If it is necessary to turn off the water heater on completion of the installation, such as on a building site or where the premises are vacant, then: Switch off the electrical supply at the isolating switches to the water heater.

- Page 25 COMMISSIONING Notes: Red LED Illuminated Solid Red or 3 x Red Flashes (Green LED Off) – If the power supply to the water heater is on and the green LED is off and the red LED is emitting a solid glow or three (3) flashes, this does not necessarily mean there may be a fault with the water heater but is indicating the water heater is operating outside of the heat pump‟s operating range.
- Page 26 COMMISSIONING Heat pump operating range (power must be available to the heat pump) The heat pump‟s operating range is when the ambient air temperature is 5°C or higher. If the ambient air temperature is between 0°C and 5°C and heating is required, the heat pump will commence operating and after a period of time, heating will switch from the heat pump to the booster heating unit in booster heating mode (three red flashes, green LED is off).
- Page 27 COMMISSIONING Possible fault condition If the heat pump has developed a fault, the heat pump will not operate and the red LED will flash a fault mode of a series of up to seven (7) flashes. The green LED may also simultaneously flash or display a solid glow. There may be a fault condition with the water heater if either: there is power available at the water heater and the green LED is off, ...

WATER SUPPLIES This water heater must be installed in accordance with this advice to be covered by the manufacturer’s warranty. This water heater is manufactured to suit the water conditions of most public reticulated water supplies. However, there are some known water chemistries which can have detrimental effects on the water heater and its operation and / or life expectancy. - Page 29 WATER SUPPLIES CHLORIDE AND PH Where the chloride level exceeds 250 mg/L the manufacturer‟s warranty does not apply to the water heater. In a high chloride water supply, the water can corrode stainless steel parts and cause them to fail. Where the pH is less than 6.0 the manufacturer‟s warranty does not apply to the water heater.
