The removal-proof screw nut must be connected to the indoor unit.
Installation method: Connect the connection pipes first to the indoor unit and

occur. Besides, the outside of connection pipe should be added with a layer of
insulating cotton to protect it from mechanical damage during installation,
maintenance and transportation.
