2.8.4 - 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.
2.8.5 - 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.

2.8.6 - 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 11), 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 11).
If draining is into a recipient (figure 12), 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.
2.9 - REFRIGERANT PIPING CONNECTION
When connecting refrigerant piping, do not let substances or gases other than the specified refrigerant enter
the unit.
The presence of other gases or substances will lower the unit's capacity, and can cause abnormally high
pressure in the refrigeration cycle.
This can cause explosion and injury.
•
The branching pipe must be installed horizontally. An angle of more than 10° may cause
malfunction.
•
DO NOT install the connecting pipe until both indoor and outdoor units have been installed.
•
Insulate both the gas and liquid piping to prevent water leakage.
