4. Adjusting the bypass
Use the following procedure to adjust the bypass:
• fully open all three valves
• slowly close valve 1 until the water pressure is increased by approximately 100 to 200 g
• Close valve 3 approximately half-way to adjust the gas pressure in the cooling system
• If the display shows „ON“ or error code EE3, close step by step the valve 2, to increase
water flow and stop when the code disappear.
Optimal operation of the heat pump occurs when the cooling gas pressure is 22 ±2 bar.
This pressure can be read on the pressure gauge next to the control heat pump panel. Under
these conditions the water flow through the unit is also optimal.
Note: Operation without a bypass or with improper bypass adjustment may result in sub-optimal heat
pump operation and possibly damage to the heat pump, which renders the warranty null and void.
5. 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 expires (see below).
3. After a few minutes, check whether the air blowing out of the unit is cooler.
4. When turn off the filter pump , the unit should also turn off automatically, if not, then
adjust the flow switch.
5. Allow the heat pump and the filter pump to run 24 hours a day until the desired water
temperature is reached. The heat pump will stop running at this point. After this, it will
restart automatically (as long as the filter pump is running) whenever the swimming pool
water temperature drops 2 degree below the set temperature.
