INSTALL THE CONNECTING PIPE
Check whether the height drop between the indoor unit and
outdoor unit, the length of refrigerant pipe, and the number of
the bends meet the following requirements:
Strong
wind
4.1 Refrigerant piping
Please pay attention to avoid the components while connect to
the connecting pipes.
To prevent the refrigerant piping from oxidizing inside when
welding, it is necessary to charge nitrogen, or oxide will chock
the circulation system.
The indoor and outdoor connecting pipe interface and power
line outlet
Vavious piping and viring patterns can be selected,such as out from
the front ,the back the side ,and undersurface, etc.（The follow display
the locations of several piping and wiring knock-off interfaces）
Table 4-1
Front out pipe
Side out pipe
Side out pipe: please remove the L-shape metal plate, otherwise
can not wiring.
Back out pipe:please wipe off the piping support rubber blanket
beside the inner outlet pipe cover of the machine while back side
getting out pipes.

outside, and then piping and wiring through this.Pay attention to the
piping the fat connecting pipe should out from the largest hole,
otherwise the pipes will be rubbed. Please do the moth proofing for
the knocked out hole, to avoid the pest processing into and destroy
the components.
4.2 Leak Detection
Use soap water or leak detector to check every joint whether leak or
not (Refer to Fig.4-2).Note:
A is low pressure side stop valve
B is high pressure side stop valve
