this may cause short circuit.
●
When operating the unit with the door and windows opened, (the room humidity is always above
80%) and with the air deflector facing down or moving automatically for a long period of time,
water will condense on the air deflector and drips down occasionally. This will wet your furniture.
Therefore, do not operate under such condition for a long time.
●
If the amount of heat in the room is above the cooling capability of the unit (for example: more
people entering the room, using heating equipments and etc.), the preset room temperature cannot
be achieved.
●
This appliance is not intended for use by young children unless they have been adequately supervised
by a responsible person to ensure that they can use the appliance safely.
●
Young children should be supervised to ensure that they do not play with the appliance.
●Do not climb on the outdoor unit or put objects on it.
●Please switch off the unit and turn off the circuit breaker during cleaning,
the high-speed fan inside the unit may cause danger.
●Turn off the circuit breaker if the unit is not to be operated for a long period.

modes, set the horizontal air flow louvers to move
within the range as recommended in the illustration
Adjusting the air flow louvers will direct air flows
to assist in reducing the room temperature and
to correct any temperature imbalance
During the “Cooling” operating mode, do not adjust
the horizontal air flow louvers to swing outside the
range as indicated by arrows in the illustration.
Do not operate the horizontal air flow louvers in
durations longer than it is necessary. Condensate
may form and drip along the horizontal air flow
louvers.
After stopping the operations of the unit by
pressing control button, the horizontal air
flow louvers will move to park at a position that
covers up the air outlet vent.
While the automatic air flow direction mode is
in operation, any physical adjustment to the
horizontal air flow louvers will shift the swing range.
