3.6 Adjusting the bypass
To pool
Out
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.
Warning : Before any work inside the appliance, you must cut the appliance's electricity supply as there is a risk
of electric shock which may cause material damage, serious injury or even death.
• Incorrectly tightened terminals may cause the terminal box to heat up, which can invalidate the warranty.
• Only a qualified and experienced technician is authorised to carry out cabling work within the appliance or to
replace the power cord.
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.
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(12V) 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.
In
Heat Pump
Use the following procedure to adjust
the bypass:
From pool
61
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.
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.
