4 Maintenance
4.1 Tasks at the start and end of the heating season
At the start of the cooling season
● Install new batteries in the remote control.
● Check that the cooling unit is installed correctly.
● Check that the cooling unit’s air flow is free of obstructions.
● Check that there are no bends, dents, or blockages in the condensate drain pipe.
● Do not start the cooling unit without air filters. Unfiltered air may cause issues in the
unit’s operation.
At the end of the cooling season
● Turn off power from the main switch.
● Clean the cooling unit and the air filters.
● To remove moisture from inside the unit, run the fan with the FAN function for 2–3
hours.
● Remove the batteries from the remote control.
Outside the cooling season, it is recommended to run the equipment for a short time
every 2 months. This will lengthen the life of the circulation pump.
4.2 Cleaning the air filter
Do not wash the filters with hot water (temperature higher than 40
degrees). Dry the filter thoroughly before reinstallation. Do not dry in
direct sunlight or near another heat source.
Clean the air filter regularly. If the air filter is dirty, air flow will be weaker, which will
increase power consumption. In extremely dusty environments, clean the air filter once
every two weeks or as often as necessary. The blue air filter prevents bacteria and
mold from growing in the dirt captured by the air filter.
1. Open the front grille and remove the air filter.
2. Vacuum the air filter.
3. If necessary, wash the filter with mild detergent. Dry carefully before reinstalling.
4. Reinstall the filter. Check that the air filter is properly in its place.
5. Close the front panel with care.
