appropriate washers.

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

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.

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 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.
