maximum operating temperature is not
exceeded.
Instructions essential for the proper
installation of the equipment are shown
here.
The final touches to all the operations
are however left to the experience of the
installation engineer in accordance with
the specific needs.
The FCW fan coil unit must be installed in
such a position that the air can be distrib-
uted throughout the room and that there
are no obstacles (curtains or objects) to
the passage of the air from the intake.
The unit must be arranged in such a way
as to make ordinary maintenance easy
(filter cleaning) and special maintenance,
as well as the access to the air vent valve
on the heat exchanger coil at a height of
190 to 220 cm.
Hydraulic connections:
Female diam. 1/2"G with flat faced flare
connections. The direction of the water
flow is indicated on the pipes of the unit.
Condensate drain connections:
FCW 22 - 32 and 42: Female with
internal diameter of Øi 16 mm.
The supply and return pipes must be
equally sized, made of copper with a
minimum diameter of 1/2", suitably insu-
lated to avoid heat dispersion and drip-
ping during cooling operation.
The water and condensate drainage
pipes and the electrical circuit wiring on
the wall must be installed beforehand.
The diameter of the hole for the connec-
tions must be at least 70 mm and the pip-
ing positioned in such a way as to main-
tain an adequate inclination along the
entire route (min.1%), to ensure evacu-
ation of the condensate produced in the
cooling operation of the fan coil unit.
The condensate drainage system must
be correctly sized. To avoid unpleasant
smells a trap is recommended if the con-
densate is connected to the sewage sys-
tem.
Supply the system with
flat faced connections.
Make the hydraulic
connections using the
appropriate washers.

The service hole for the piping can be
located on the right or left of the unit.
The support wall must be sturdy and not
subject to vibrations.
Do not install the unit near sources of
heat, vapour or flammable gas.
Do not install in a position exposed to
direct sunlight.
Installation
To install the unit, proceed as follows:
- Put the template on the wall, fixing it
solidly with at least six or more screws
or expansion blocks of a type that is
adequate for the thickness of the fix-
ing wall, through holes near the edge
of the template.
The template must be fixed flush to
the wall, perpendicular to the floor
and perfectly level. Failure to respect
these conditions will cause water to
drip out of the drain tray.
- Remove the cabinet.
- The FCW unit permits 4 connection pos-
sibilities.
For connections through the wall make
a hole with a diameter of 70 mm,
inclined downwards by 5-10 mm.
For connections sideways and down-
wards, remove the knock-outs of the
cabinet in the direction of the pipes.
- Carry out the electrical connections as
shown on the wiring diagram.
- If you intend to control the fan coil
unit with the PFW2 wired control
panel make the connection with the
unit as indicated in the wiring diagram:
remove the connector of the Infra Red
receiver from the circuit board of the
unit and connect the wired control
panel to it . The cable is 4 metres long.
- Make the water connections. If the
pipe is repeatedly bent it may break.
The unit's pipes indicate the direction of
the water flow
- Connect the condensate drain outlet
to the drainage line and make sure it
works properly.
- Insulate the pipes properly.

- Position the FCW unit on the template
after passing the pipe through the hole
or in the channelling in the wall. Check
that the fan coil is level horizontally
and vertically.
- When all the installations have been
completed (electrical and hydraulic
connections, fan coil unit fixing and
condensate drain connection) close the
hole in the wall with a suitable filler.
- Vent the coil using the air valve pro-
vided.
- Complete the refitting of the compo-
