THANK YOU FOR PURCHASING A NEPTUNE FULL INVERTER HEAT PUMP. Please read the manual thoroughly before installing or using the product.
Only qualified technicians must install the product. Keep this manual for future reference.

SECTION 1:

IMPORTANT WARNINGS AND SAFETY INFORMATION

This manual contains important information about the installation, operation, and safe use of this product. This information should be given to the owner and/or operator of the heat pump. When installing and using the heat pump, basic safety precautions should always be followed. Failure to follow safety warnings and instructions in this manual can result in serious injury and/or damage to your equipment.

5.2: POSITIONING AND LOCATION OF HEAT PUMP
The heat pump must be installed in accordance with the following diagrams. Distances in the diagram are the minimum distance allowed. The heat pump must be positioned on solid level ground (concrete slab) outdoors in a place with good ventilation. Do not install the heat pump in an enclosed area. Ensure there is sufficient access space for installation and maintenance.

5.3: INSTALLATION OF THE HEAT PUMP 1. Install the 4 rubber feet onto the heat pump’s legs, using the supplied bolts.
2. Install the drain plug into the drain hose, then attach the drain plug to the drain hole underneath the heat pump.

Visit www.neptuneheating.com.au for more information

Page 9 of 36

3. Run the drain hose downhill to a suitable location, for example a garden or nearby stormwater drain. When the heat pump is running, there will be condensation water discharged from the drain hose.

4. Ensure the heat pump is equipped with a circuit breaker and electrical isolator switch.

5. The heat pump requires a pool pump (supplied by the user). Refer to the Specifications Table in Section 4.2 for recommended pump water flow and maximum head information for the model being installed.

6. Install the unions as follows:

STEP 1

STEP 2

STEP 3

7. Connect the inlet downstream, after the pool pump and filter.

8. Connect the outlet upstream before chlorinator, acid injection or other chemical dosing systems.

9. Create a flow bypass between the inlet and outlet pipework.

5.4: WIRING OF THE HEAT PUMP
1. Wiring must be connected by a qualified professional electrician, according to the details set out in this manual.
2. The heat pump must be hard wired.
3. Ensure power is disconnected during installation or service. Always comply with the national and local electrical codes and standards. Ensure electrical cable size is adequate for heater requirements at the installation location.
4. The layout of power and signal cables should be neat and orderly. Considering environmental conditions (ambient temperature, direct sunlight, rain, grid voltage, cable length etc), the cross-sectional area of the cable can be appropriately increased.
5. Set breaker or fuse according to the below table.
6. Check that there is adequate voltage and current available at the heater connection to run the unit. Refer to the below table. Voltage ranges outside these parameters will damage the heat pump.

SECTION 6:

INITIAL START-UP

Check all wirings carefully before turning on the heat pump.
6.1: PRE-STARTUP INSPECTION
1. Check installation of the entire heat pump and the pipe connections according to the installation instructions in this manual.
2. Check the electrical wiring according to the electrical wiring diagram and earthing connection in this manual.
3. Ensure that the main power is connected properly.
4. Ensure there are no obstacle/blockages in front of the air inlet and outlet of the heat pump.
6.2: INITIAL STARTUP
1. Ensure the inlet, outlet and bypass water flow valves are fully open, then turn the pool pump on.
2. Check there are no water leaks and verify adequate flow to and from the pool.
3. As the heat pump is hardwired, turn on the isolation switch.
4. Press the Power symbol on the heat pump touchpad.
5. In order to protect the heat pump, the heat pump is equipped with a Delayed Start function. When starting the heat pump, the pool water pump will start to run for 3 minutes, then after another 30 seconds, the heat pump fan motor and compressor will start to run.
6. Check for any abnormal noises from the heat pump.
7. Check the air that is coming out of the heat pump fan, this air temperature should be 5oC-10oC cooler than the ambient air temperature.
8. Test the Flow Switch is working correctly. With the heat pump still running, turn the pool water pump off. If the Flow Switch is working, the heat pump should turn off automatically and the heat pump touchpad will display an error code E3 (insufficient water flow protection).
9. It is time to adjust the bypass water flow valve and calibrate the flow rate though the heat pump. Ensure all valves (inlet, outlet, bypass) are open. Then fully close the bypass valve and turn the heat pump to the maximum temperature.
10. Wait 3-4 minutes for the heat pump to run.

Page 16 of 36

Visit www.neptuneheating.com.au for more information

11. Check the difference in temperature between the inlet temperature and outlet temperature displayed on the heat pump’s LCD screen.
12. Slowly open the water flow bypass valve to increase the temperature differential between the inlet and outlet. Closing the bypass valve will decrease the temperature differential.
13. Adjust the bypass valve until optimum differential of 2oC-3oC is achieved. Wait two minutes between each adjustment.
14. The water flow bypass valve is set up correctly when the temperature difference between the inlet and outlet is 2oC-3oC. Once this has been achieved, lock the position of the bypass valve if possible.
15. The initial startup is complete. Choose your desired speed and temperature settings, and allow the heat pump to run 24 hours per day until the desired pool temperature is reached. This can take several days.
SECTION 7:

OPERATING INSTRUCTIONS

7.1: IMPORTANT OPERATING INFORMATION
· For the heat pump’s ideal operating performance, the ideal ambient air temperature is 15oC-25oC. · In case of power failure during the operation of the heat pump, the heat pump will automatically restart
when the power is restored. · Turn off the power during thunderstorms and severe weather. · Do not use or store combustible gas or liquid such as thinners, paint or fuel near the heat pump. · Always keep the heat pump in the upright position. · The heat pump is designed for heating swimming pools; do not use it for any other purpose. · The surroundings of the heat pump must be kept clear to avoid restricting ventilation. · The heat pump must be kept away from any source of fire. · Do not put anything into the inlet or outlet, and do not remove the fan cover. · If any abnormal circumstances occur e.g. abnormal noises, smells, smoke and leakage of electricity,
switch off the main power immediately and contact your authorised dealer. · Do not try to repair the heat pump yourself or open the casing. · To extend the life of your heat pump, ensure the pool water pump is on before starting the heat pump, and
turn the pool water pump off after the heat pump is turned off.

SECTION 9:

MAINTENANCE

9.1: REGULAR MAINTENANCE Regular maintenance can be carried out by the user.
1. Regularly check there are no obstacles blocking the air inlet and outlet of the heat pump. 2. Regularly check all unions, bolts and other visible connections for leaks or signs of wear.
9.2: ANNUAL MAINTENANCE QUALIFIED TECHNICIAN ONLY
Annual maintenance must be carried out by a qualified professional technician.

Turn off the main power supply of the heat pump before cleaning, examination and repairing. Do not touch the
electronic components until the LED indication lights on the PC board turn off.

2. Clean the evaporator with household detergents or clean water. NEVER use gasoline, thinners or any similar fuel.
3. Check bolts, cables and connections are in good condition. 4. If any spare parts are required, contact your authorised dealer. Only use genuine spare parts. 5. Only qualified professional technicians must handle/refill gas.
SECTION 10: WINTERISING
Do not allow water to freeze inside the heat pump, as this may damage the titanium heat exchanger and void your warranty.
When using the heat pump under 2oC, make sure there is always water flow. Follow these steps when the heat pump will not be used for an extended period of time e.g. Winter.
1. Turn off the main power supply to the heat pump.

Visit www.neptuneheating.com.au for more information
