IOM_FCW-FCCW_10a120_207995_181001_EN
FAN COIL INSTALLATION
Before installing the appliance, remove the housing (if present). Raise the flaps covering the control panel
and the water connections. Remove the two screws fixing the housing to the fan coil load-bearing
structure. Gipping the rear of the housing, remove it as shown in the Pic. 5 (NOTE: be careful of the lugs
on the front part of the load-bearing structure, as shown in Pic.10).
Put the cabinet in the packing box to prevent it from being soiled or damaged (Pic.6)
Offer the appliance up to the required point of installation and mark, through the fixing holes, the points on
the wall where the holes should be driller for the 4 screw anchors, as shown in Pic. 7.
Remove the appliance from the point of installation; drill the holes where marked on the wall (see Pic. 8)
and insert the screw anchors. Place the appliance against the wall and fix it by tightening the screws into
the anchors see (Pic.9). Carry out the water and electrical connections as described in the relevant
paragraphs.

IOM_FCW-FCCW_10a120_207995_181001_EN
To replace the housing.
Take the cabinet from the packing box. Standing in front of the fancoil, lift cabinet, holding it by the sides,
and tilt it (Pic. 10).
Insert the lugs A into the relative slots B (Pic.11). Pivot the cabinet on its base until it is aligned with the
wall. Raise the flaps covering the control panel and water connections and tighten the two fixing screws
(Pic.5).
Fan coil units have the following operating limits:
- it can't be installed in areas with anomalous heat and humidity conditions
- it can't be installed outdoors
- it can't be installed in explosive environments
- it can't be installed in a corrosive atmosphere
WATER CONNECTIONS
CONNECTION TO THE WATER MAINS
Always use a wrench and nose key for connection of the coil
to the pipes (Pic. 12). If the solenoid valve is installed, suitably insulate the valve body with
insulating material (Pic. 13).
ATENTION!

IOM_FCW-FCCW_10a120_207995_181001_EN
Connect the water inlet and outlet pipes, observing the indications given on the side of the appliance.
Correctly insulate the water supply pipes to prevent dripping during the cooling mode of operation. A
shutoff valve should be inserted on the water supply pipe and balancing valve on the outlet pipe. The valve
body and balancing valve should also be properly insulated to prevent dripping. It is the installer’s
responsibility to insulate properly and the manufacturer cannot be held liable for any insulation work.
NOTE:
It is always advisable to install the solenoid valve. In the heating mode of operation the solenoid
valve reduces consumption because upon reaching the set temperature the circulation of water is
stopped to avoid wasting energy (the fan coil would otherwise continue to heat like a radiator, even
with the motor at a standstill). In the cooling mode of operation the solenoid valve stops the
circulation of water when the set temperature is reached, this stopping the internal exchanger from
continuing to condense water with possible undesirable dripping into the floor. It also reduces
chiller operation with consequent energy savings.
CONDENSATE WATER DRAINGE
The condensate drain pipe should slope downwards by at least 3 cm/m and should not have ascending or
throttled section in order to ensure a regular flow of water. It is advisable for a trap to be fitted. The
condensate drain pipe should be connected to a rainwater drainage system. Do not use sewage system to
avoid possible smells in the event of evaporation of the water in the trap. Upon completion of work, check
that the condensate flows out properly by pouring water into the tray (see Pic. 14 and 15). The condensate
water drainage system should be fabricated in a workmanlike manner and should be periodically checked.
The manufacturer cannot be held liable for any damage caused by dripping in the absence of a solenoid
valve or of periodic maintenance of the drainage system.

IOM_FCW-FCCW_10a120_207995_181001_EN
Failure to comply with the indicated connections may cause motor burnout!
ATTENTION!
ELECTRICAL CONNECTIONS
Before carrying out electrical connections, ensure that the electricity supply to the supply line has been cut
off, checking that the on-off switch is in the OFF position. Only qualified electricians should carry out the
electrical connections.
Check that the mains supply is single-phase 230 Vac/1/50 Hz (± 10%).
Operating the appliance with voltages outside the above limits could cause malfunction and renders the
warranty null and void.
The fan coil power supply line should be fitted with at least a switch isolator in conformity with European
standard EN60947-3. Make sure that the electrical system is suitable for providing not only the working
current required by the appliance, but also the necessary current for powering household and other
electrical appliances already in use.
Any electrical and mechanical alterations or tampering render the warranty null and void. The motor and
accessories power cables in channels or ducts should remain inside the same until they are inside the
appliances.
The cables should be sufficiently long so that they are not permanently taut or create throttling or pressure
on metal parts (see Pic. 16). The power cables should be sufficiently long so that in the event of accidental
tugging the active wires are subjected to stress before the earth wire. Connect the earth wire to the relative
terminal marked with the symbol.
Check the earth connection. Comply with the safety regulations in force in the country of installation.
CONNECTIONS TO THE TERMINAL BLOCKS
WITHOUT CONTROL PANEL
The electrical connections should be made to the terminal block on the side of the appliance
(Pic. 17). Each terminal is identified by the label to be found on the terminal block.
WITH CONTROL PANEL
The electrical connections should be made directly to the control panel, as shown by the relative
wiring diagram. If the control panel has an electronic temperature sensor (NTC) this sensor will
be powered by mains voltage (230Vac/1/50 Hz) and is therefore provided with double
insulation.

IOM_FCW-FCCW_10a120_207995_181001_EN
Under no circumstances should the connections to the terminals L, M, M be changed!
ATTENTION!
CHANGING THE MOTOR SPEEDS OF ROTATION
The fan coil motor has 6 speed settings, 3 of which are connected in the factory (red, blue and black wires
connected to the motor auto-transformer). To use other speeds than those wired up in the factory, the red
(minimum), blue (medium) and black (maximum) wires may be connected onto 3 of the 6 numbered
terminals (1…6), taking into account that the speeds follow a sequence as shown in Pic. 18.

IOM_FCW-FCCW_10a120_207995_181001_EN
Protect the appliance with a cardboard box if building works are still being carried out (Pic. 19).
ATTENTION!
TESTING THE FANCOIL
Upon completion of installation, scrupulously check both the water and the electrical connections before
switching on the appliance.
Before mounting the housing (if present), fill the system, bring it up to pressure and bleed. Make the
water circulate and check for leaks.
Check correct operation of the fan coil at the 3 speeds, of the solenoid valves and of the minimum
temperature thermostat (if installed). The cabinet is covered by a protective film: remove it before
fixing the housing to the appliance.
Remount the housing (if present), otherwise the customer has the responsibility of concealing the
appliance.
TURNING THE COIL
The fan may reach the speed of 1,000 rpm. Do not insert objects or hands into the electric fan. The motor
becomes hot during operation; wait for it to cool before touching it. During the heating mode of operation
the exchanger and the connecting pipes may become very hot (80°C).
Wait for the exchanger to cool before touching it or protect hands with suitable gloves. The heat
exchange water coils are suitable for working up to maximum pressure of 8 bar. To turn the coil,
proceed as follows:
1. Remove the housing (if present).
2. Disconnect the terminal block or the control panel (2), if present, from the side of the appliance.
3. Remove the condensate collecting tray in horizontal models or the galvanized panels in vertical models
(4).
4. Remove the coil fixing screws (5).
5. Take out the coil (1), being careful not to be cut by the fi ns and not to damage them.
6. Remove the knockouts (6) on the opposite side of the fan coil (using a screwdriver), to allow the coil
connections to pass through.
7. Position the coil, turning it without tipping it upside down, so that the fittings are in line with the holes left
by the knockouts.
8. Fix the coil using the previously removed screws (5).
9. Shift the control panel (2), if present, or the terminal block (fixing it to the side opposite the water
fittings), the motor and sensor cables (3), if present, fixing them with their grips. Ensure that the cables
pass through the hole in the side of the appliance, protecting them with the relative grommet. If it proves
easier to carry out this operation by separating the wires from the terminal blocks, mark the positions of the
wires to avoid making mistakes when reconnecting.

IOM_FCW-FCCW_10a120_207995_181001_EN
10. Reconnect the wires to the relative terminal blocks or control panel (2), taking care that they are
correctly positioned.
11. Replace the condensate collecting tray (4) in horizontal models or the galvanized panels in vertical
models.
12. Remount the housing (if present).
USING THE APPLIANCE
This appliance should only be used by adults. Make sure that children do not touch the controls or play
with the appliance. This appliance has been designed for use as a heating and cooling appliance in rooms
that are clean and frequented by persons (with normal pollution). Avoid using for any other purpose. This
appliance should not be used in places with suspended dust/powder or in potentially explosive
atmospheres, in very damp environments or in the presence of oil in suspension or in particularly
aggressive atmospheres.

IOM_FCW-FCCW_10a120_207995_181001_EN
USING THE CONTROL PANEL
If the appliance has a built-in control panel, raise the flap and proceed as follows.
Heating mode
Put the season selector switch from the off position ( ) to the winter position ( ). The fan starts.
In models with minimum temperature thermostat (optional), the fan starts when the internal heat
exchanger is sufficiently hot. If the water is not hot enough, the fan does not start.
Cooling mode
Put the season selector switch from the off position ( ) to the summer position ( ). The fan starts
immediately.
Selecting the fan speed
Put the selector switch to the required speed. The higher the speed the quicker the room will be
heated/cooled, although appliance operation will be noisier (Pic. 22).
Automatic temperature adjustment (for control panel with built-in thermostat)
This control panel has a built-in temperature sensor, which measures the room air temperature. This
information is used for the automatic control of the fan or introduction of water into the internal exchanger
through the solenoid valve (optional).
The appliance this keeps the room at the temperature set by the user.
The room temperature may be set approx. between 10°C and 30°C. If the appliance does not have a
built-in control panel, but is controlled by a wall-mounted thermostat, refer to the thermostat
instructions for use.
