.2.4 Refrigerant piping connection
The piping can be run in the 3 directions indicated
by numbers in the picture. When the piping is run
in direction 1 or 3, cut a notch along the groove on
the side of the indoor unit with a cutter.
Run the piping in the direction of the wall hole and
bind the copper pipes, the drain pipe and the
power cables together with the tape with the drain
pipe at the bottom, so that water can flow freely.

.2.7 Indoor unit condensed water drainage
The indoor unit condensed water drainage is
fundamental for the success of the installation.
1).Place the drain hose below the piping, taking
care not to create siphons.
2).The drain hose must slant downwards to aid
drainage.
3).Do not bend the drain hose or leave it protruding
or twisted and do not put the end of it in water. If
an extension is connected to the drain hose,
ensure that it is lagged when it passes into the
indoor unit.
