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.

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.
