3.6 Adjusting the bypass
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 machine 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 degree.
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 (slow type; curve D)
and to use adequate wiring (see table below).
For horizontal models (Hydro Pro7, 10, 13 ): remove the panel to the right of the fan opening.
(Hydro Pro 5: remove the top panel).
Connect the electrical wires to the terminal block marked ‘ POWER SUPPLY ’.
A second terminal block marked ‘WATER PUMP ’ is located next to the first one. The filter pump switch(24V) can be
connected to the second terminal block here. This allows the filter pump operation to be controlled by the heat
pump or the extra dry contact.
Out In
Heat Pump
Please take below steps to adjust the
by-pass:
1. Valve 1 wide open. Valve 2 & valve 3
closed.
2. Slowly open valve 2 & valve 3 by half,
then close the valve 1 slowly to increase
the water flow to valve 2 & valve 3.
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.
