Installation (Cont.)
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 it
more than three times at one point.
• When extending rolled pipe,
straighten the pipe by unwinding it
gently, as illustrated (Fig. 11).
Connections to the indoor unit
• Remove the indoor unit pipe cap and check that
there is no debris inside.
• Insert the nut and create a flange at the extreme
end of the connection pipe.
• Tighten the connections by using two wrenches
working in opposite directions (Fig. 12).
Water drainage from the indoor unit
The condensed water drainage from the indoor unit is fundamental for the
success of the installation.
• Place the drain hose below the piping,
taking care not to create siphons.
• The drain hose must slant down-
wards to aid drainage (Fig. 13).
• 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.
• 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.
1) Insert the pipe connection into the
relative slot.
2) Press to join the pipe connection
to the base.

Installation (Cont.)
Installation of the outdoor unit
• The outdoor unit should be installed on a solid wall, or on the ground, and
fastened securely.
• Before connecting pipes and cables, decide on the best position on the
wall, leaving enough space for easy maintenance.
• Fasten the support to the wall using screw anchors that are particularly
suited to the type of wall.
• Use the largest size wall anchors that will suit the size and weight of the
unit, keeping in mind that the mounting will need to support the weight and
vibration of the unit for many years to come, without loosening.
• The unit must be installed following all relevant local regulations.
Water drainage from the outdoor unit
Condensed water and ice formed in the outdoor unit while in heating mode
Fig. 15
can be drained away through a drain
pipe.
• Fasten the drain port in the 25mm
hole placed in the part of the unit, as
illustrated (Fig. 15).
• Connect the drain port and the drain
pipe.
• Make sure that water is drained into a
suitable place.
Electrical connections
• Take off the cover.
• Connect the cable wires to the
terminal board using the same
numbering as in the indoor unit.
• For the electrical connections, see
the wiring diagram on the back of the
cover (Fig. 16).

Installation (Cont.)
Connecting the pipes
Screw the flare nuts to the outdoor unit coupling with the same tightening
procedures described for the indoor unit. To avoid leakage, pay attention to
the following points:
Bleeding
Air and humidity left inside the
refrigerant circuit can cause
compressor malfunction. After
having connected the indoor
and outdoor units, bleed the air
and humidity from the refrigerant
circuit by using a vacuum pump
(Fig. 18). Detailed instructions
follow on the next page.
• Tighten the flare nuts using two
wrenches, taking care not to
damage the pipes (Fig. 17).
• If the tightening torque is not
sufficient, there will probably be
some leakage. With excessive
tightening torque there may also
be some leakage, as the flange
could be damaged.
• The best way to tighten the
connections is using a fixed
wrench and a torque wrench, as
illustrated in Fig. 12 on page 13.
