Service and Maintenance MAINTENANCE Service Parts Maintenance Procedure Air Filter - Remove any dust adhering to the filter by using a vacuum cleaner or wash in lukewarm water (below 40°C) with a neutral cleaning detergent. - Rinse the filter well and dry before placing it back onto the unit. - Do not use gasoline, volatile substances or chemicals to clean the filter.
Troubleshooting Troubleshooting When a malfunction of the air conditioner unit is detected, immediately switch off the main power supply before proceeding with the following troubleshooting procedures. The following are common fault conditions and simple troubleshooting tips. If any other fault conditions which are not listed occur, contact your nearest local dealer.

Troubleshooting Phase Protector The unit with Scroll Compressor can only rotate in one direction. For this reason, a protective device (phase protector) is fitted to prevent incorrect wiring of the electrical phases. When the three phases are not connect- ed correctly, the phase protector operates, and the unit will not start. This device is located in the control box of the outdoor unit.
