MINIMUM INSTALLATION DISTANCES
(*) Min. 100 mm
Note: the unit must slope by at least 2 mm/m towards the condensate drain.
( * )
Min. 400mm only in if the Air purifier Module is fitted.
HYDRAULIC CONNECTIONS
WATER PIPE CONNECTION
Make sure the diameter of the water pipes is adequate for
the actual length of the piping and in any case not less than
the diameter of the connection on the unit. When con-
necting the water pipes to the coil, take care not to dam-
age the coil manifold. During this operation, hold the coil
connections firm with a spanner to avoid damaging them.
The fittings are located on the back of the unit looking at
the air outlets.
CONNECTING THE WATER PIPING
This operation must be carried out with particular care.
The unit is fitted with a gravity drainage condensate drain
pan with an open connection on the back of the unit. The
pipe should have an internal diameter of at least 16 mm.
The drain connection has an external diameter of 18 mm.
Proceed according to the following instructions (see figure).
1. Connect the condensate drain hose to the pan outlet
with a hose clip.
2. Make sure the drain pipe has a slope of at least 2 cm/m
without obstructions or bottlenecks.
3. Fit a siphon. By eliminating the pressure drop caused by
the fan, this prevents air being sucked up by the drain
hose.

4. Connect the condensate drain pipe to a rainwater
drainage system. Do not connect to the sewage system
as odours may be sucked up if the water in the siphon
evaporates.
5. After connecting, check correct drainage of the con-
densate by pouring water into the pan.
IMPORTANT
gravity drainage may be converted into forced drainage by
fitting the condensate drain pump available as an accessory.
