Fig.5-13
With the connection part to the indoor unit, please note not to
impose 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 breadthwise
shall not exceed 20m. When the pipe is over long, a bracket
must be installed to prevent winding.
Refer to the following figures to install the pipes.

●
Between climbing section length (L) and pipe inner diameter
(d)should satisfy the relation: L*d*d≤650000 (L and d units are
mm).
that is water in the climbing section can not more than 500 ml,
otherwise will cause poor drainage, flowing water leakage
problems.
●
It must accord to the requirement to install the water pipe. Suggest
using water pipe with the inner diameter 25mm, and the climbing
Panel component wiring must accord to the figure display,
length is not over than 1m.
otherwise will cause the abnormal operation. Connecting wire
installation must follow the figure display, otherwise will cause
the electric control box cover cannot close, if there are wire
clamped will cause air leakage and condensation of the panel
and so on.
Inner diameter: dmm
Heat insulation
Display part of the panel should be installed at the pipe side of
the unit body.
There are 6/7 panel installation screws, after confirmation then
to be fastened.
