During recycling refrigerant, make sure the liquid valve and gas valve are closed completely, and the power
supply is cut off before disassembling the connection pipe.
If connection pipe is disassembled when the compressor is still operating, air may get into the system. In this
case, system pressure will increase and compressor will be damaged.
During installing the unit, make sure the connection pipe is connected properly before starting the compressor.
If the compressor is started before finishing connection of connection and when the cut-off valve is opened, air
may get into the system. In this case, system pressure will increase and compressor will be damaged.
The indoor unit and outdoor unit shall be connected properly with required wire. The wiring terminal shall be
secured properly without affecting by exterior force directly.
