summer/winter switch (B) in the position
appropriate for the cycle in course (towards
the top = summer, towards the bottom =
winter).
- Version 2 controls:
Put switch (B) in the position appropriate for
the cycle in course (
winter).
b) If there is one (in the electronic or
microprocessor thermostats), turn the room
temperature thermostat (C) to the required
temperature.
c) Check that the fan is working properly on all
three speeds by using switch (D) and taking
into account any other checking instruments,
for example the trip thermostat.
d) In FR - FC versions take the transparent
film off the cover. Put the cover back on by
inserting the lower flanges on the attachments
on the frame, adjusting the positions and
fixing it with the two screws placed at the
bottom of the grille flaps. Tighten the two
screws which fix the cover to the side frame
brackets at the bottom back of the cover itself
(fig. 10) Put the air filter in position and fix it
with the plastic filter grips which come with
their screws in a bag in the pack.
5. COMPONENT REPLACEMENT
To replace any of the components listed
below, consult an authorised Technical
Service Centre. For safety and quality
reasons, use only the original manufacturer's
replacement parts.
WARNING! All of the following operations
must be carried out with the fan heater
switched off and disconnected from the
electricity supply.
5.1 FAN SYSTEM
Get access to the fan system by removing the
filter, cover and any panels where the heater is
installed in a casing. For vertical versions F -FC
take the rubber condensation disposal joint off
from under the tray.
Disconnect the electrical wiring terminals from the
electric motor (see electrical diagrams figs. 7-8)
Loosen the four screws which fix the system to
the appliance framework at the sides.
Take out the fan system carefully holding the tray
and taking care not to damage the insulating
material on the side of the framework.

Before inserting the new fan system, check the
state of the internal surface of the heat exchange
system and if necessary clean it.
Put the new fan system in place and repeat the
above operations in reverse.
5.2 HEAT EXCHANGE SYSTEM
Gain access to the interior of the fan heater by
removing the filter, cover and any panelling in the
case of installation in casing.
In horizontal versions FR - FCR, detach the
condensation disposal joint from the tray and take
off the tray itself by undoing the four screws which
fix it to the framework.
Close the locks on the hydraulic attachments or in
some way separate the fan heater from the rest of
the system. Disconnect the hydraulic attachments
from the heat exchanger using spanners or
wrenches and loosen the four screws which fix it
to the framework at the sides. Loosen as much as
possible the four screws which hold the fan system
too, so that the exchanger can be extracted without
damaging the insulation material.
Gently push open the sides of the framework and
extract the exchanger, rotating it so that the pinions
connecting it to the framework also come out.
To insert and connect the new exchanger, repeat
the above operations in reverse.
