ABOUT OUTDOOR UNIT
• Even if the operation is stopped, the outdoor
unit fan continues to rotate for 10~60 seconds
to cool down the electrical parts.
• In heating operation, condensed water and
defrosted water is discharged from the outdoor
unit. Do not block the drain port as the water in
the drain may freeze in a cold area.
• Even during cooling operation, the water
condensed in the pipe, etc. may flow out from
the outdoor unit.
• When installing the outdoor unit under eaves,
etc. of the apartment, install a bush and drain
pipe on the drain port for drainage treatment.
