•Cables between indoor and outdoor unit shall be connected
in good order using specified cables and connecting
terminals be fixed well wit�out being affected by external
force. Fire may result from poor connection or fixture.
•
Electrical cover s�all be fixed well, ot�erwise, fire or electric s�ock
may result from entry of dust and moisture.
•Be sure not to make wrong connection.
•Electric shock may result from wrong grounding.
•Wires between indoor and outdoor terminal block shall be
marked with number for corresponding connection.
•Tighten terminal screws to avoid looseness.
•After tightening of the screws, pull the wires slightly to verify
whether they are tightened.
•The air conditioner can operate correctly only when the
wires are connected correctly to the terminal block.
When the air conditioner is controlled by the remote
controller, indoor unit electrical board will memorize
operation mode, set temperature and fan speed. If there
is a power-off during operation, Auto restart function is
enabled to restart the air conditioner after recovery of
power supply. If the air conditioner operates in the mode
of “I FEEL CONTROL” before power-off, the mode will be
memorized. In “I FEEL CONTROL” mode, air conditioner
operation depends on indoor temperature at restarting.
How to set Auto Restart Function
•The operation setting will be reserved after 10 seconds of
remote controller operation.
•When the Auto ON/OFF timer is activated, the timer setting will
be cancelled in the event of power-off or power failure. As Auto
Restart function is equipped inside these models, once the
power is recovered, the air conditioner will start to operate three
minutes later.
•If the air conditioner is turned off by the remote controller before
power-off, Auto Restart function will be disabled due to power
button’s OFF status in the remote controller.
•In order to prevent impulse current from affecting the power
supply, please arrange a sequence to start other household
appliances to avoid simultaneous power-on.
Be sure to place drainage hose under refrigerant pipe.
Don’t make the drainage hose uplifted or bended.
Don’t bind up the hose by pulling it.
Be sure to bind up the drainage hose with commercially available
insulated material when the hose goes through room.
