Resistance functioning is controlled by a thermofuse - probe
applied directly onto the resistance.
When the thermofuse - probe intervenes it interrupts
resistance functioning.
Any intervention of the thermofuse - probe leads to
the replacement of the same in order to restore normal
functioning.
INSTALLATION
ATTENTION: before carrying out any intervention, make
sure that the electric power supply has been disconnected.
CAUTION: before carrying out any work, wear the
appropriate individual protection devices.
ATTENTION: The appliance must be installed in compliance
with national regulations on this subject.
ATTENTION: the resistances reach high temperatures, before
intervening on the unit make sure that the temperatures
of the components do not constitute a danger for the
operator.
ATTENTION: in the units with the RXLE accessory mounted,
the flow vents must be all free. It is prohibited to obstruct
the vents, even partially.
WARNING: the electrical connections, maintenance,
installation of the fan coils and their accessories must
only be performed by persons with technical-professional
requisites regarding installation, transformation, extension
and maintenance of plants and who can check the same
regarding safety and functionality (in this manual they
will be identified with the general term "staff with specific
technical skills").
Here find the essential indications for correct installation of
the appliance. The completion of all operations, according to
specific requirements, is left to the experience of the installer.

ASSEMBLY SEQUENCE

Apply the RXLE accessory before installing the FCL units.
The RXLE accessory is supplied with all elements necessary
for correct installation.
The installer is responsible for precise assembly in compliance
with Safety Standards.
PRELIMINARY OPERATIONS:
ATTENTION: mount a magnet circuit breaker omnipolar
switch on the power supply line max 10A 250V (IG) with
minimum opening distance of the contacts of 3mm.
The power supply line must have a section that is not lower
than 2.5mm² with wire whose quality is not lower than
N07V-K.
RESISTANCE ASSEMBLY OPERATIONS:
- Disassemble the polystyrene cabinet from the FCL unit.
- Disassemble the fan from the FCL fan unit.
- Install the 2 stainless steel coil support brackets (1) supplied.
Two brackets are already installed on the FCL unit.
The coil support brackets are supplied with attachments for
the resistances and for the blocking elements.
- ATTENTION: The fixing position of the two resistances

is very important! The resistances must be installed as
indicated in the figures. The resistance with thermofuse -
probe (4) has two metal references (2) to be positioned on
the coil support bracket.
- The resistance element (5) without thermofuse - probe must
be positioned first in the attachments the nearest to the
base.
- The resistance element (4) with thermofuse - probe must be
positioned in the second series of attachments the furthest
away from the base. The two metal references (2) on the
resistance act as a reference and guide. They indicate the
exact position of the resistance on the attachment.
- Block the resistance elements with the four locking elements
supplied (6), applied onto the brackets and fixed with a
screw.
- Connect the resistance tables to the connector (7) in the
ventilation compartment.
- Remove the actuator unit (8) from the FCL valve in order
to increase the space available in the hydraulic fittings
compartment.
- Gather the resistance cables and take the excess length
outside of the bulkhead (9), in the hydraulic fittings
compartment, through the two rubber fairleads. The cable
tensioning clip fixed externally to the bulkhead is used to
fix the excess length of cable.
- Check that the cables are not against the surface of the
resistances, are adherent to the bulkhead and do not
interfere with the fan, that their path does not cross sharp
edges and they do not undergo traction.
- Re-mount the actuator unit on the FCL valve.
- Re-mount the fan on the FCL fan unit.
- ATTENTION: do not use connection V1 but only connections
V2, V3 and V4.
- Carry out the tests and checks necessary to guarantee state-
of-the-art installation.
MAINTENANCE
ATTENTION: the use of suitable individual protection devices
is mandatory.
ATTENTION: the resistances reach high temperatures. Before
intervening on the unit make sure that the temperatures
of the components do not constitute a danger for the
operator.
Maintenance can only be performed by staff with specific
technical skills.
Before re-activating the resistance, after intervention of the
safety devices, look for the cause and restore the conditions
for functioning in complete safety.
The thermofuse only interrupts functioning of the electric
resistance. For its replacement it is necessary to access the
unit.
