SAFETY SYMBOLS
1
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 estro fan coil from the indications stated on
the carton package.

USE AND OPERATING LIMITS
Galletti S.p.A. shall not be held liable where 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 where 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 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 is 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, where existing, by unscrewing the 4 fastening screws
reachable through the lifted side doors (figure 3, page 20). In case
of FU models, unscrew the 2 screws on the front panel.
Fix the bearing unit to 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 intake and an easy removal of the filter for the FL and FC models. In case
of ceiling-mountable models FU and FC, check that the installation height
does not exceed the maximum height shown in figure 4 page 20, in order
to avoid excessive hot air stratification in the upper part of the room; in case
of greater installation heights we suggest to proceed with the back suction
from the lower part of the room. The installation heights shown in the figure
refer to the maximum running speed.
Carry out the hydraulic connections to the heat exchanger and in case of
cooling operation, to the water drainage system.
We suggest to provide for the water inlet from the bottom side of the heat
exchanger and the outlet on the upper side.
Bleed the air from the heat exchanger operating on the air-vent valves (10
hexagon wrench) located beside the water connections of the heat
exchanger.
For a better water drainage lean the drain pipe downwards at least 3 cm/
m avoiding loops or narrowing on its way.
5.1
ROTATION OF THE HEAT EXCHANGER
It is possible to orient the attachments of the heat exchanger on the
opposite side operating as follows:
- remove the front panel of the bearing unit (4 screws), in case of model
FL or the main drip tray in case of models FU and FC;
- remove the sheet of the heat –exchanger cover (2 screws);
- remove the heat exchanger (4 screws) fixed on the side panels of the
bearing unit;
- remove the lower baffle;
- disconnect the motor cables from the terminal strip
- remove the terminal strips and reassemble it on the opposite side
- take out the motor cable and place it on the opposite side; remove the
rubber raceway;
- 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°
- reassemble the baffle on the bottom side
- insert the attachments into the specific openings by removing the pre-
cut slots and then fix it to the unit using the screws supplied;
- reassemble the sheet of the heat exchanger cover;
- insert the rubber raceway into the hole previously used for the drain pipe,
reassemble the cable fastener on the side panel, insert the cables
connecting them to the terminal strip;
- reassemble the unit’s front panel (4 screws) in case of model FL or the
main drip tray for the models FU and FC;
- close the holes previously used with drip proof material.
5.2
INSTALLATION FOR THE FC FLUSH-MOUNTED MODEL
The air outlets should not be placed immediately under a socketFor the
FC
flush-mounted model, perform the connection between the fan coil and the
ducts, and place damping material between the duct and the unit.
The ducts, in particular the outlet ones, must be insulated.
In order to avoid air back suction on the fan coil, keep a minimum distance
between the air outlet and recovered air flow as shown in figure 5 page
20.
The minimum installation height should not be lower than 1.8 metres from
floor level.
Provide for an inspection port to the unit.
