Troubleshooting and Maintenance
Routine Maintenance
Only a qualified service person is allowed to perform maintenance.
Before accessing to terminal devices, all power supply circuits must be disconnected.
Do not use water or air of 50°C or higher for cleaning air filters and outside panels.
Note:
1. Do not operate the air conditioner with the filter uninstalled, otherwise dust would come
into the unit.
2. Do not remove the air filter except for cleaning. Unnecessary handling may damage the
filter.
3. Do not clean the unit with gasolene, benzene, thinner, polishing powder or liquid
insecticide, otherwise it would cause discoloration and deformation of the unit.
4. Do not wet the indoor unit in case of electric shock or fire hazard.
Increase the frequency of cleaning if the unit is installed in a room where the air is extremely
contaminated.(As a yardstick for yourself, consider cleaning the filter once a half year.)
If dirt becomes impossible to clean, change the air filter.
