3.2.3 Connection Pipe Installation
3.2.3.1 Installation Notice and Requirement on Connection Pipe
①.
Indoor unit adopts special joints that can't be disassembled. The installation
method is the same as the unit with ordinary joints. However, because the
joints can't be removed, if the connection is not good and causes leakage, the
joints need to be cut and welded again for replacement.
②.
The removal-proof screw nut must be connected to the indoor unit.
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.
