Installation method: Connect the connection pipes first to the indoor unit and
then to the outdoor unit. When bending a connection pipe, be careful not to damage
the pipe. Do not over-tighten the screw nut, otherwise leakage will 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.
