• Connecting the pipes and binding them
(Fig. 3-7)
Wrap the connection cable, the drain pipe
and wires securely and evenly with tape, as
shown below.
- e condensed water generated at the back
of the indoor unit is collected in a special
tank and conveyed outside the room. Do
not put anything else in the tank.
INSTALLING THE INDOOR UNIT (Fig. 3-8)
- Push the pipe through the hole in the wall.
- Place the clamp on the back of the indoor
unit, on the installation panel hook, move
the indoor unit sideways and make sure it is
safely attached.
- e pipes can quickly and easily be connect-
ed by liing the indoor unit with cushioning
material placed between the unit and wall.
Remove when the pipes have been connect-
ed.
- Push the bottom of the indoor unit upwards
along the wall, then move the unit sideways
and downwards to ensure it safely attached.

CONNECTING THE WATER PIPE
e water pipe must be connected by expert tech-
nicians using two spanners for tightening the pipes
of the indoor unit (Fig. 3-9).
Note: Read the installation instructions for
connecting the water pipes of the fan coil with
built-in acceleration device (Fig. 3-10).
- When connected for the rst time, com-
pletely expel the air from the coils through
the outlet valve (g. 3-11).
3.3 WIRING DIAGRAM
Note: e appropriate function is indicated in
the dotted part (can be selected by the user if
required).
Pursuant to applicable national regulations,
xed wiring must have an integrated single-pole
disconnect device with a distance between con-
tacts of at least 3 mm on all poles and a residual
current device (RCD) of at least 10 mA.
e device must be installed in compliance with
the national regulations in force.
- remove the front protection and take o the
plate (Fig. 3-12).
- Connect the power cable and the signal line,
then congure if necessary (Fig. 3-13).
