Please refer to figure 7 for further details.
c. Attach the upper bracket present in the rear part of the indoor unit to the upper hook of the fixing bracket
(pos. L - figure 8).
d. Move the unit laterally to ensure it is correctly attached to the fixing hook (7).
e. If the connection pipes are already fitted in the wall, directly proceed with the connection of the drain pipe.
Piping connection is easily performed by lifting the indoor unit and introducing cladding between the same
and the wall (pos. N - figure 8). Remove the cladding once connection has been completed.
f. Push the lower part of the indoor unit towards the wall to attach it to the fixing bracket (pos. M - figure 8).
g. Try and move the indoor unit laterally and vertically to make sure that it is attached securely.
2.2.4 - Drain pipe connection (figure 9)
a. Insert the drain pipe (A), making sure that it slopes downwards.
b. If necessary, connect an extension (C) to the drain pipe, isolate the joint with a protection pipe (B).
Tightly wind the connection point with a Teflon tape so as to ensure good tightness and im-
pede possible leakage. The part of the drain pipe which remains inside shall be wrapped in a
foam rubber sleeve to impede the formation of condensation.
c. Remove the air filter and pour a small quantity of water inside the drain tray to check that water flows out
correctly from the unit.
2.2.5 - Piping and protection wrapping connection (figure 10)
Evenly wrap the connection cable, drain pipe and electric cables with electrical tape, as illustrated in figure 10.
Given that the condensate water from the rear of the indoor water is collected in the "Pond Box"
tray and taken out of the compartment, do not put anything in the tray.

2.2.6 - Connection of the condensate drain line
Connect a drain pipe, of appropriate length, to the indoor unit condensate drain pipe, and block it with a strap.
Make it run inside the duct parallel to the system pipes, fastening it to the same using straps.
Do not tighten the straps excessively in order to prevent damage to the insulation of the
pipes and narrow the drain pipe.
Where possible, make the condensate liquid flow directly into a rainwater gutter.
If the drain pipe is fed into a sewage system, it is necessary to bend the pipe in order to
create a siphon (figure 20), in order to avoid the diffusion of unpleasant odours into the
environment.
The siphon bend must never be at a level below 1500 mm from the lower wire of the appli-
ance (figure 20).
If draining is into a recipient (figure 21), this must never be closed so as not to prevent
counter-pressures such to compromise the operation, and the pipe itself must never reach
the level of the liquid deposited.
