Copper Pipe from Indoor Unit
Service Port
(Only the GAS Side
Valve has this port)
CAUTION
The drain pipe of the indoor unit must be heat-insulated, or it,as
well as the connections of the indoor unit, will condense dew.
Hard PVC binder must be used for the pipe connection. Make
sure there is no leakage.
With the connection part to the indoor unit, please ensure not to
apply pressure on the side of indoor unit pipes.
When the declivity of the drain pipe downwards is over 1/100,
there should not be any winding.
The total length of the drain pipe, when pulled out transversely,
shall not exceed 20m. When the pipe is overlong, a prop stand
must be installed to prevent winding.
Refer to the figures below for the installation of the pipes.
