INSTALLATION

INSTALLING THE UNIT
- Choose the place where to install the
unit according to the layout of the room,
the number of units to be installed
and any limitations imposed by the
architecture. Check that the chosen
place facilitates installing and servicing
the unit.
- Install four M8 threaded rods into the
ceiling to hold the frame.
VEC_I allows 2 installation options thanks
to the grill prepared to be fixed in two
positions:
A) for suspended ceiling installation with
reduced space that requires units with
small dimensions.
B) allows (increasing total height) to
increase the difference in level between
condensate drain and suspended
ceiling by a further 30 mm, to make
the realisation of the condensate drain
ducting even easier, in order to prevent,
in most cases, the necessity for a
condensate drain pump.
To install the VEC_I unit, proceed as
follows:
- open the cardboard box
- if necessary, mount any accessory before
installing the unit on the ceiling
WARNING: consult the relevant manuals
of the accessories
WATER CONNECTIONS
- Make the water connections.
- In the event of disassembly and
reinstallation, use new gaskets.
Refer to the size data for the position, type
and diameter of the water connections.
CONDENSATE DISCHARGE
Assemble the condensate discharge
connection supplied. Make sure you seal
the connection between the drip tray and
the fitting with silicone. The condensate
drain network must be properly scaled
and the piping situated in such a way
- lift the unit carefully and, keeping it
slightly inclined, attach it to the 4
threaded bars using 8 nuts, 4 of which
are self-locking. Operate the nuts to
adjust height; finally, check that the unit
is installed in a horizontal position
- lay the hydraulic pipes through the
suspended ceiling to the attachment
plate on the unit
- make the hydraulic connections as
described in the relative chapter
- bring the condensate discharge pipe so
that it matches the relative fitting on the
condensate discharge device
You are advised to adequately insulate
water lines and/or fit the auxiliary
condensate drain tray (available as an
accessory), to prevent dripping during
the cooling function.
as to keep an adequate slope along
the route (min. 1%). If condensate
is discharged into the sewage system,
install a siphon to prevent the return of
unpleasant odours into the room.

- drain the system via the drain valve
- bring the power supply and the control
cables close to the electrical box
- adjust the position of the unit from the
support bracket by means of the nuts so
that the unit is level and the frame rests
slightly on the suspended ceiling
- start the fan coil unit and carry out
an operation test; the functions are

After installing, check the seal on the
