SWING
When power turned on, louver will fully open, then shut off; when power turned off, all shutt off.
Whenever "SWING" button is pressed once, up-down louver(s) will oscillate between up and down, or stop
oscillating and stay still, or be turned off.
Control with the remote controller to adjust up/down air flow direction, NOT to
adjust louvers during swinging.
In Cool or Dry mode, louver swings to blow air downward in (1), (2) and (3) zones.
In Heat mode, louver swings to blow air downward in (3), (4) and (5) zones.
In SWING mode, the deflector will not oscillate left-right back and forth, if otherwise stated. Air flow right / left
direction change shall be done by manul adjustment. Conduct this adjustment when unit and all moving parts
stop running. If adjust during operation, the auto swinging louver may pinch your fingers.

OPERATION OF THE UNIT

A.AUTO MODE
When started, operation mode will turn into COOL or DRY or HEAT mode upon room temperature as shown in
the following table. Once AUTO operation mode is set, unit will change operation mode as the room temperature
changes. If unit restarts after last operation stops for two hours, it will start in the same mode as set before
operation was stopped. Press SWING button to change air flow direction up/down.

B.COOL MODE
Pointing remote/line controller to the unit, press MODE button until COOL is shown. Press TEMPERATURE
ADJUSTMENT button to change the setting temperature. In this mode, you can press SWING button or
MANUAL SWING button, if available, to change up/down air flow direction. Press FAN SPEED button to change
the fan speed of indoor unit. Once the temperature settled is reached, both indoor and outdoor unit will stop to
run. Outdoor unit will work again as soon as the indoor air temperature sensor feels the room temperature is 1 or
o
2 F higher than set temperature.
Once set temperature is reached, outdoor unit compressor and fan motor will stop working right away, outdoor
reversing valve stays un-energized.
1) If "circulation" function is built in (2008.06 or ealier production), then the indoor fan will keep on rotating to
circulate the air in the room, so that air temperature stratefication will not be caused, and then compressor will
not come on and go off often.
2) If "circulation" function is NOT built in (2008.06 or later production), then the indoor fan will keep on rotating for
60 to 90 seconds to blow out the residual cooling capacity left on cold coil, then shut off.
Once the sensed indoor temperature is 1 or 2 F above set temperature and the 3-mintue compressor restarting
protection time is passed, indoor unit fan motor and outdoor unti compressor and fan motor will resume to work
right away.
C.DRY MODE
Pointing remote/line controller to the unit, press MODE button until DRY is shown. In this mode, you can press
SWING button or MANUAL SWING button, if available, to change up/down air flow direction. Press FAN SPEED
button to change the fan speed of indoor unit.
D.FAN MODE
Pointing remote/line controller to the unit, press FAN button until DRY is shown. In this mode, you can press
SWING button to change up/down air flow direction. Press FAN SPEED button to change the fan speed of indoor
unit.
