8. Maintenance and Inspection

- Check the water inlet and drainage often. The water and air inflow into the system should be 

sufficient so that its performance and reliability does not get compromised. You should clean the 

pool filter regularly to avoid damage to the unit caused by clogging of the filter.

- The area around the unit should be spacious and well ventilated as shown in section 5.3. Clean the 

sides of the heat pump regularly to maintain good heat exchange and to save energy.

- Check if all processes in the unit are operational.

-  Check  the  power  supply  and  cable  connections  regularly.  Should  the  unit  begin  to  function 

abnormally or should you notice a smell from an electrical component, arrange for timely repair or 

replacement.

- You should also purge the water if the unit will not work for an extended period of time. You should 

check all parts of the unit thoroughly and completely fill the system with water before 

turning it on again afterwards.

If your heat pump has been stored for a long time, perform the following steps when re-starting the 

system:

1. Inspect the system for any debris or damage to the case.

2. Clean the evaporator fins with a soft cloth if necessary. Make sure the evaporator fins are clean. 

Blocking the air intake will cause insufficient operation and will result in lower production of heat.

3. Check the fan for blockages.

4. Connect the water inlet and outlet.

5. Turn on the pool water circulation pump to start the water flow to the heat pump.

6. Restore electrical power to the heat pump and press the reset button on the RCD.

8.1 Water chemistry

Special care should be taken to keep the chemical balance of your swimming pool within following 

limits:

Failure to keep the swimming pool water between the above mentioned limits will void the warranty.

When the concentration of one or more products mentioned above becomes too high, irrevocable damage to 

your heat pump may occur. Make sure that you always install water treatment equipment after the heat pump. 

When an automatic chemical feeder is installed in the plumbing, it must be installed downstream of the heat 

pump.
