Remote Control Manual.
NOTE ON LOUVER ANGLES
When using COOL or DRY mode, do not set
louver at too vertical an angle for long periods
of time. This can cause water to condense on
the louver blade, which will drop on your floor
or furnishings. (See Fig.A)
When using COOL or HEAT mode, setting the
louver at too vertical an angle can reduce the
performance of the unit due to restricted air
flow.
Do not move louver by hand. This will cause the
louver to become out of sync. If this occurs, turn
off the unit and unplug it for a few seconds,
then restart the unit. This will reset the louver
.
