Use the following procedure to adjust the bypass:
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.
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.
