• Are you sure that there are no obstacles near
the air outlet of the outdoor unit?
Such obstacles may result in declined perfor-
mance and increased running noises.
• If abnormal noises occur in use, stop the opera-
tion of the air conditioner, consult your dealer.
Regarding drainage of drain piping
• Is the drain piping executed to perform com-
plete drainage?
If proper drainage is not carried out from the out-
door drain pipes during air-conditioning operation,
chances are that dust and dirt are clogged in the
pipe. This may result in a water leakage from the
indoor unit. Under such circumstances, stop the
operation of the air conditioner, and then consult
your dealer or our service station.
