Cleaning the heating circuit
Flush the condenser regularly with a flushing device. The heating water
can get contaminated by oxidation products, remainders of lubricants and
sealants. If these substances enter the heating circuit, they can reduce the
performance of the condenser in the device.
Danger
Always make sure that the device is disconnected from the power
supply before opening and cleaning the device.
Warning
Parts and fluids may be hot.
1. Connect the flushing device directly to the supply and return pipes of
the condenser of the heat pump.
2. Flush the condenser contrary to the direction of flow.
2.1. Install a filter to keep the heat exchanger clean and to avoid
failures.
3. Reattach the supply and return pipes, to both heat exchangers.
4. Make sure the water pressure in the system is at the required level.
5. Bleed all air from the system.
6. Install the side cover.
7. Install the screws to attach the side cover.
8. Turn the power back on.

Important
Clean the fans, evaporators and condensate drainage at the
beginning of each heating period.
Check the condensate collector regularly and clean it if
necessary, to guarantee proper draining.
Warning
Always make sure that the device is disconnected from the power
supply before opening and cleaning the device.
1. Remove the side cover of the air side.
2. Clean the inner side of the heat pump.
Caution
Do not use sharp or hard objects, to avoid damage to the
evaporator and the condensate pan.
3. Install the side cover.
