3. INSTALLATION ANd CONNeCTION
3.5 Swimming Pool Heat Pump Electrical Wiring
NOTE: Electrical wiring and earthing should comply with local wiring rules, including a means of
isolating all active conductors with air gap contact separation.
3.6 Initial start up of the unit
NOTE: In order for the heat pump to operate, the water pump must be operating to circulate water
through the heat exchanger
Start up procedure – After installation is completed, you should follow these steps:
Caution: Ensure glued pipework is fully cured before running/starting the recirculation water pump.
1. Fully open the bypass valves ensuring that the bypass pipe is closed off
2. Prime the pump
3. Purge air from the heat exchanger by running the pump
4. Start the heat pump. For 3 phase units, the direction of rotation can be checked with a pressure switch error message
EE04 or the phase monitor will indicate “incorrect phase”
5. Adjust bypass flow so that the temperature out is 2 degrees Celsius more than the temperature in
6. After the heat pump has been running a few minutes check that the air leaving the heat pump is cooler than the
ambient temperature.
7. With the heat pump running, turn the water pump off. The heat pump will then go into standby mode after a few
seconds.
8. We recommend that the heat pump runs continually to achieve desired water temp (NOTE:THIS MAY TAKE SEVERAL
DAYS DEPENDING ON CLIMACTIC CONDITIONS AND EXPOSURE TO WEATHER) When the desired temperature is
reached the heat pump will go into standby mode until the temperature drops to 2 degrees below the set temperature
Water Flow Switch
–
Each heat pump is equipped with a flow switch that turns the unit on when the water pump is
running. The unit turns off automatically when the water pump is stopped
Time Delay –
The heat pump software is programmed with a time delay to ensure that the heat exchanger is flooded
before the compressor starts
