System Configuration
Be sure always to clean the unit before use at the beginning of summer and winter.
(Dirt and dust caught in the air filter cause a drop in airflow, which leads to a decline in
performance.)
When using the unit in a location where dirt may easily accumulate, clean the unit more frequently.
Once every 2 weeks is recommended.
Ask your DAIKIN dealer how to clean them.
Clean the drain pan periodically, or drain piping may be clogged with dust and may result in water
leakage.
Ask your DAIKIN dealer how to clean them.
If the ambient air of indoor unit is so dusty, install the optional Dust Cover which prevent dust from
falling into drain pan.
If no drain water is seen, water may be leaking from the indoor unit. Stop operation and consult
the service shop if this is the case.

other room before you use the fan operation.
