BEFORE THE INSTALLATION
Carefully read this handbook .
Installation and maintenance should be carried out by technical personnel
qualified for this type of machine, in compliance with current safety regulations.
When receiving the unit please check its state verifying if any damage occurred
during the transport.
For installation and use of possible accessories please refer to the pertinent
technical sheets.
Identify model and version of the fan coil series FC/N from the indications stated
on the carton package.

USE AND OPERATING LIMITS
Galletti S.p.A. shall not be held liable if the unit has been installed by non-qualified
personnel, it has been used improperly or under conditions that are not permitted,
the maintenance operations specified in this manual have not been carried out
or if non original spare parts have been used.
Operating limits are shown here below; all other uses are considered improper:
- thermal fluid: water
- water temperature: from 5°C to 95°C
- maximum operating pressure temperature: 10 bar
- air temperature: from 5°C to 43 °C
- power supply: +/- 10%
In choosing where to install the unit, comply with the following points:
- The heating unit should not be placed immediately under a socket.
- do not install the unit in rooms where inflammable gases are present
- do not let water be sprayed directly on the unit;
- install the unit on ceilings or walls that bear its weight. Leave enough space all
around for proper operation and maintenance of the unit.
Keep the unit in its packaging until it is ready to be installed, to prevent dust getting
inside it.

INSTALLATION
WARNING :
On the fan-coil install a switch (IL) and/or all remote controls in a position out
of the reach of persons who are in a bathtub or shower.
Remove the cabinet by unscrewing the 4 fastening screws reachable through the
lifted side doors (figure 3, page 18).
Remove the protecting spacers (useful for transport only) from the cabinet sides.
Unscrew the fastening screw (1) and remove the spacer from the side of the
bearing structure (2), as shown in Fig. 4 page 18.
Install the bearing unit onto the wall using the 4 mounting slots and the supplied
anchor screw, keeping the unit at least 100 mm above the floor for a proper air
suction and an easy pulling out of the filter.
Carry out the hydraulic connections to the heat exchanger and in case of cooling
operation, to the condensate drainage system.
WARNING : tighten the hydraulic connections making sure to block the
manifold with the appropriate wrench to prevent damage to the heat exchanger.
We suggest to provide for the water outlet from the bottom side of the heat-
exchanger and the inlet on the upper side.
For a better condensate drainage lean the drain pipe downwards at least 3 cm/
m avoiding loops or narrowing on its way.
It is possible to direct the fittings of the heat-exchanger toward the opposite side
as follows:
- remove the heat-exchanger cover (2 screws);
- remove the heat-exchanger (4 screws) fixed on the side panels of the bearing
unit;
- disconnect the connection cables from the Faston connector located on the
internal side panel;
- remove the Faston connector and fixing base from the internal side panel (snap
fitting)
- take out the motor cable and place it on the opposite side; remove the rubber
snap bushing;
- remove the drain pipe and place it on the opposite side; set the drop breaker
pipe in the place of the closing cap of the drip tray;
- turn the heat-exchanger 180° and insert it on the side panel removing the pre-
cut slots; fix it to the unit using the screws supplied;
- reposition the heat-exchanger cover;
- insert the rubber snap bushing into the hole previously used for the drain pipe,
reassemble the cable fastener on the side panel and insert the cables;
- fit the fixing base/Faston connector onto the side panel facing the new hydraulic
fittings side and restore the electric wiring (see diagram in figure 6)
- close the manifold through-holes, no longer used, with drip proof material.
Bleed the air from the heat-exchanger operating on the air-vent valves (10 hexagon
wrench) located beside the water fittings of the heat-exchanger.
In case of recess mounting, comply with the minimum distances reported in figure
7.
Carry out the electrical wiring after having turned the power off in compliance
with the current safety regulations
closely adhering to the diagram associated
with the control panel provided as accessory.
The fan coil unit is equipped with a 3-speed motor. The cables associated with
each speed are shown in the wiring diagram of figure 5 page19, and associated
caption.
Check that the power supply corresponds to the rated power reported on the unit
nameplate.
Electric connections in dotted lines should be carried out by the installer.
Each fan-coil requires a switch (
IL
) on the feeder line with a distance of at least
3 mm between the opening contacts, and a suitable safety fuse (
F
).
