How to clean the air fi lter
When the remote controller indicates “Time to clean filter”, clean the air filter.
•
It indicates after running for a certain time.
NOTE
For cleaning, do not use any of the following:
•
Volatile liquid such as benzene, gasoline and thinner
•
Polishing compounds
•
Rough materials such as a scrubbing brush
• You may change the time of indication “Time to clean filter”.
If the indoor unit is used in a space where the air is too contaminated, ask your local dealer for solution�
Contamination
Time until indication is displayed
Normal
2500 hours
(equivalent to one year)
More contaminated
1250 hours
(equivalent to a half year)
• If it becomes diffi cult to remove contamination from the air fi lter, replace the air fi lter.
(Air fi lter for replacement is a separately sold accessory.)
• Do not remove the air fi lter except when cleaning. Unnecessary handling may damage the fi lter.
(This product is not provided with an air fi lter as a standard accessory.)
• Do not attach objects other than the genuine air fi lter (e.g., kitchen paper) to the air inlet.
Otherwise, the performance of the air conditioner will be degraded, and icing or water leakage may result.
•
This product is a ceiling mounted duct type air conditioner.
Installing under roof
If the air filter (sold separately) is used, request a special contractor for the cleaning of the air filter.
Not installing under roof
Always use the long-life filter chamber (sold separately). Be sure to request your dealer for the installation of the long-life chamber. For the methods
of mounting, dismounting, and cleaning the air filter, refer to the manual provided with the air filter.
• Be sure to use the separately sold fi lter chamber.
Request your dealer for the installation of the filter chamber.
• Be sure to clean the air fi lter at the beginning of the cooling or heating season.
(A decrease in the airfl ow volume of the air conditioner will result and the performance of the air conditioner will be degraded if the air fi lter is clogged
with dust or dirt.)
Increase the frequency of cleaning if the unit is installed in a room where the air is extremely contaminated.
After completing cleaning and installing an air filter, turn off the indication of “Time to clean filter” on the remote controller�
