5).The cable connecting the outdoor and indoor
units must be suitable for outdoor use.
6).The plug must be accessible also after the
appliance has been installed so that it can be
pulled out if necessary.
7).An efficient earth connection must be
ensured.
8).If the power cable is damaged, it must be
replaced by an authorized Service Centre.
10.2.4 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.
10.2.5 Connecting the pipes.
Do not remove the cap from the pipe until
connecting it, to avoid dampness or dirt
from entering.
If the pipe is bent or pulled too often, it will
become stiff. Do not bend the pipe more
than three times at one point.
When extending the rolled pipe, straighten
the pipe by unwinding it gently as shown in
the picture.
10.2.6 Connections to the indoor unit
1).Remove the indoor unit pipe cap (check that
there is no debris inside).
2).Insert the fare nut and create a flange at the
extreme end of the connection pipe.
3).Tighten the connections by using two wrenches
working in opposite directions.
10.2.7 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.
4).If the piping is installed to the right, the pipes,
power cable and drain hose must be lagged and
secured onto the rear of the unit with a pipe
connection.
Insert the pipe connection into the relative slot.
