6)
Connect the indoor unit, BU module and outdoor unit with the room air conditioner piping and cord
available from our standard parts. This installation manual describes the correct connections using the

Before installation, check the parameter of power cord and make sure that it complies with the power
supply requirement on the nameplate. Make sure the power supply is safe.

This air conditioner must be properly grounded through the receptacle to avoid electric shock. The ground
wire shouldn’t be connected with gas pipe, water pipe, lightning arrester or telephone line.
9)
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.

Do not power on until all installation work is complete.
11)
During installation, make sure that the refrigerant pipe is attached firmly before you start up the compressor.
Do not operate the compressor under the condition of refrigerant piping not attached properly with valve
open. This may cause abnormal pressure in the refrigeration cycle that leads to breakage and even injury.
12)
When installing and relocating the air conditioner, do not mix gases except the specified refrigerant
(R410A) to enter the refrigerant cycle. If air or other gas enters the refrigerant cycle, the pressure inside the
cycle will rise to an abnormally high value and cause breakage, injury, etc.
