8. Maintenance and Inspection
- Check the water inlet and drainage often. The water and air inow into the system should be
sufcient so that its performance and reliability does not get compromised. You should clean the
pool lter regularly to avoid damage to the unit caused by clogging of the lter.
- 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 ll 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 ns with a soft cloth if necessary. Make sure the evaporator ns are clean.
Blocking the air intake will cause insufcient 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 ow to the heat pump.
6. Restore electrical power to the heat pump and press the reset button on the RCD.

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.
