1. Optimum performance will be achieved within these
operating temperatures. If air conditioner is used
outside of the above conditions, certain safety
protection features might activate.
2. If the air conditioner runs for a long time in cooling
mode and the humidity is high (over 80%), condensed
water may drip out of the unit. Please set the vertical air
flow louver to its maximum angle (vertically to the floor),
and set HIGH fan mode.
Manual Operation
Units are equipped with a switch to run emergency operation
mode. It can be accessed by opening the front panel. This
switch is used for manual operation in case the remote
controller is lost or inoperative.
NOTE
The unit must be turned off before operating the manual
control button. If the unit is operational, continue
pressing the manual control button until the unit is off.
This is NOT the recommended way to operate the unit.
To restore the remote controller operation, use the
remote controller directly.
Adjust the horizontal louver
using the remote controller.
Adjust the vertical louver
manually. To set the vertical
airflow (Up--Down) direction
perform this function while the
unit is in operation.
Use the remote controller to
adjust the air flow direction. The
horizontal louver can be moved
at a range of 6⁰ for each press,
or swing up and down
automatically.
Please refer to the DC4812VRF
REMOTE CONTROL USER GUIDE
Air Flow Direction control
Caution
Do not operate the air conditioner for long periods with
the air flow direction set downward in cooling or
dehumidifying mode. Otherwise, condensation may
occur on the surface of the horizontal louver causing
moisture to drop on the floor or on furnishings. Do not
move the horizontal louver manually unless it is necessary,
always use the remote controller.
When the air conditioner is started immediately after it
was stopped, the horizontal louver might not move for
approximately 10 seconds. Open angle of the horizontal
louver should not be set too small, as COOLING or
HEATING performance may be impaired due to restricted
air flow. Do not operate unit with horizontal louver in
closed position. When the air conditioner is connected to
power (initial power), the horizontal louver may generate a
sound for 10 seconds, this is a normal operation.
