(5) Before installation, check the power cord if it complies with the power supply requirement on the nameplate.
Make sure the power supply is safe.
(6) This air conditioner must be properly grounded through the receptacle to avoid electric shock. The ground
wire shouldn’t be connected
to gas pipe, water pipe, lightning rod or telephone line.
(7) If refrigerant leaks while work is being carried out, ventilate the area. If the refrigerant comes in contact with a
flame, it produces toxic gas.
(8) Do not power on until all installation work is complete.
(9) During installation, make sure that the refrigerant pipe is attached firmly before you run the compressor.
Do not operate the compressor with gas pipe and liquid pipe valve open.
This may cause abnormal pressure in the refrigeration cycle that leads compressor damage or personal
injury.
(10) During the pump-down operation, make sure that the compressor is turned off before you remove the
refrigerant piping.
This may cause abnormal pressure in the refrigerant cycle that leads to compressor damage or personal
injury.
(11) When installing the air conditioner, do not mix gases other than the specified refrigerant (R410A) to enter the
refrigerant cycle.
(12) If air or other gas enters the refrigerant cycle, the pressure inside the cycle will rise to an abnormally high
value and cause compressor damage or personal injury.
(13) This appliance is not intended for use by persons (including children) with reduced physical, sensory or
mental capabilities, or lack of experience and knowledge,.
(14) Children should be supervised to ensure that they do not play with the appliance.
