ing due to the thermal expansion of
the different components (plastics and
metals). This does not cause damage
to the unit if the maximum operating
temperature is not exceeded.
Instructions essential for the prop-
er 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 distributed 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 21 - 31 and 41: 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
insulated to avoid heat dispersion and
dripping during cooling operation.
The water and condensate drainage
pipes and the electrical circuit wiring
on the wall must be installed before-
hand. The diameter of the hole for the
connections must be at least 70 mm
and the piping positioned in such a
way as to maintain an adequate incli-
nation along the entire route (min.1%),
to ensure evacuation of the condensate
produced in the cooling operation of
Supply the system
with flat faced con-
nections.
Make the hydraulic
connections using the
appropriate washers.

the fan coil unit.
The condensate drainage system must
be correctly sized. To avoid unpleasant
smells a trap is recommended if the
condensate is connected to the sewage
system.
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 fixing 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
possibilities.
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 dia-
gram: 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.

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 tem-
plate 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
