WATER CONNECTIONS
The water connections are made with flat
fittings complete with seal gaskets (supplied).
In the 4-pipe version of the unit, it is essential
to install the valve accessory for the hot water
coil; use the supplied gaskets. The accessory

For the proper discharge of air and water through the special valve is necessary to remove the condensate drain pan, as shown on the previous
page
For proper water drainage and must make sure that the hydraulic connections main are closed.

CONDENSATE DISCHARGE CONNECTION
During cooling operation the indoor unit
removes humidity from the air. The
condensate water must be eliminated
by connecting the appropriate discharge
coupling to the piping of the condensate
discharge system.
In units with "Module 600", the polystyrene
tray has a hole that allows for the complete
draining of the condensate (useful in the
case of disassembly). The drainage hole must
always be closed again with the rubber plug
provided.
The units are fitted as standard with a pump/
float device for raising the condensate from
the tray to the drainage point; it consists of
an electronic card, an electric pump with non-
return valve, and a float with a 3-level sensor
(ON, OFF and Alarm).
The power supply for the floating pump device
must never be interrupted.
In the event of an alarm, the float device

comes complete with gaskets for connection
to the system.
Information for the correct installation of the
valve is contained in the accessory instruction
booklet.

interrupts the flow of water in the coil.
The basin is fitted with an overflow hole to
ensure that the condensate water runs off if
the floating pump device is not working. In
this case dripping can be seen from the grille.
The pump allows a maximum head of 80cm
from the level of the suspended ceiling; if this
is not high enough you will have to use an
auxiliary device.
You are advised to use rigid piping that is heat-
insulated, to avoid condensation on the outer
surfaces.
SC1 = Condensate discharge (male Ø 16mm)
SC2 = Condensate discharge with siphon (male Ø
16mm) Ensuring a vertical section of at least 5 cm
(from the pump outlet, upward)
The delivery and return pips must be equal,
suitably scaled and insulated to avoid
heat dispersion and dripping during cold
functioning.
