CAUTION
DO NOT put your fingers into the panel of
the blower and suction side. The high speed
fan inside may cause injury.
DO NOT operate the unit for extended
periods of time in COOL or DRY mode with
the vertical airflow direction set with too
much of a downward angle. This could
cause condensation to form on the surface
of the vertical louver and allow moisture/
water droplets to drop onto furnishings or
the floor.
DO NOT move the vertical louver manually,
as this could cause it to become out of sync.
If this occurs, follow these steps:
1. Turn off the power to the unit.
2. Remove the wireless module from the
back of the front cover.
3. Turn off the power to the circuit at the
breaker.
4. Wait a few seconds and turn the power
back on at the breaker.
5. Reinstall the wireless module into the
front cover.
6. Turn the power to the unit back on.
NOTE: After a quick restart, the vertical louver
may remain static for approximately
10 seconds.
NOTE: The open angle of the vertical louver
should not be set too small when using COOL or
HEAT mode, as it will restrict airflow and reduce
performance of the unit.

Louver
Adjustment of the vertical and horizontal louvers
will change airflow direction of the indoor unit to
prevent discomfort and/or uneven room
temperatures.
Adjust the vertical louver using the remote.
Adjust the horizontal louver manually by
hand.

Adjust Vertical Airflow (Up/Down) using Vertical
Louver (Fig 2.2):
This function is performed by using the
SWING/DIRECT button on the remote control, while
the unit is operating. The Vertical louver can move in
small increments for each press, or continuously
swing up and down automatically. Please refer to the
“Remote Control User Manual” for further details.
Adjust Horizontal Airflow (Left/Right) using
Horizontal Louver (Fig 2.3 & Fig 2.4)
The angle of the horizontal louver must be set
manually. Move the deflector rod, located on the
underside of the unit, by pushing the tab to manually
adjust the airflow from side to side as desired. For
some units, the horizontal angle of the airflow can be
set by the remote control. Please refer to the
“Remote Control User Manual” for further details.
