3.6 Adjusting the bypass
Use the following procedure to adjust the
bypass:
1.
Open Valve 1 & 2 half way.
2. Close valve 2 until control shows
NO Or EE3 screen.
3.
Slowly open Valve 2 until pool
Temp shows on screen.
4. If it shows ‘ ON ’ or ‘ EE3 ’ on display,
it means the water flow into heat
pump is not enough, then you
need adjust the valves to increase
the water flow through the heat
pump.
Must not have Valves open Full.
How to get the optimum water flow:
Please turn on the heat pump under heating function, firstly close the by-pass then open it slowly to start the heat
pump (the heat pump can't start running when the water flow is insufficient).
Continue to adjust the by-pass, at the meantime to check the Inlet water temp. & Outlet water temp, it will be
optimum when the difference is around 2 degrees.
3.7 Electrical connection
Note: Although the heat pump is electrically isolated from the rest of the swimming pool system, this only prevents
the flow of electrical current to, or from the water in the pool. Earthing is still required for protection against short-
circuits inside the unit. Always provide a good earth connection.
Before connecting the unit, verify that the supply voltage matches the operating voltage of the heat pump. It is
recommended to connect the heat pump to a circuit with its own fuse or circuit breaker and to use the appropriate
wiring.
Connect the electrical wires to the terminal block marked ‘ POWER SUPPLY ’.
A second terminal block mark ed ‘WATER PUMP ’ is located next to the first one. The filter pump (max. 5 A / 240 V)
can be connected to the second terminal block here. This allows the filter pump operation to be controlled by the
heat pump.
3.8 Initial operation
Note: In order to heat the water in the pool (or hot tub), the filter pump must be running to cause the water to
circulate through the heat pump. The heat pump will not start up if the water is not circulating.
After all connections have been made and checked, carry out the following procedure:
1. Switch on the filter pump. Check for leaks and verify that water is flowing from and to the swimming pool.
2. Connect power to the heat pump and press the On/Off button on the electronic control panel. The unit will
start up after the time delay.
