SECTION A - GENERAL INFORMATION
1. PRINCIPAL CHARACTERISTICS
1.4 ASSEMBLY CHARACTERISTICS
1.1 APPLIANCE CLASSIFICATION
1.4.1 Available versions
The F-FR-FC-FCR fan heaters are defined as
"air treatment terminals for winter and summer
air conditioning".
1.2 EC CONFORMITY - CERTIFICATION
The EC symbol guarantees that the appliance
conforms to EEC machinery directive EEC/98/
37, low tension directive EEC/73/23,
electromagnetic directive EEC/89/336 and any
subsequent amendments. The appliances have
the Eurovent certificates and the symbol
guarantees conformity to the data declared.
1.3 FUNCTIONAL DESCRIPTION
The fan heaters consist essentially of a system
of heat exchange between the liquid circulating
inside the exchanger (hot or cold water) and the
air flow controlled by a fan system. The outside
air is taken in by the fans and sent out to the heat
exchanger which heats the air in winter or cools
it in summer. During the summer cycle,
depending on the heat-hygrometric conditions of
the outside air, water condensation is formed
and collected in the appropriate container so that
it can be disposed of.
The treated air is emitted through the appliance
grille or through the outlet units built in to the plant.
The appliances come as standard with fittings
for 2 pipes. For 4-pipe plants with two independent
circuits, there is an optional supplementary heat
exchange system. The fan heater has a remote
control (supplied separately). A choice can be
made from various available versions.
The fan heaters are available in 6 different sizes
and in the following versions:
FR
- Vertical with casing
For wall installation, under windows or in
any other free space or position which offers
technical or functional advantages.
FC - Horizontal with casing
For direct ceiling installation in all situations
where there is not enough free wall space.
FCO - Vertical built in
Supplied without any casing for invisible
installation in custom made panels and
connection to intake and output grilles and
outlets.
FCR - Horizontal built in
As above, supplied without casing for
invisible installation in panelling or dropped
ceiling.
For the F and FR versions, there is also a G
variation with frontal air intake grille complete
with filter.
1.4.2 Component characteristics
The support frame is made in zinc plate of an
appropriate thickness and comes with fixings
already in place for attaching the appliance to a
wall or ceiling with hooks and brackets as well as
mountings for the various components and
accessories. Internal surfaces are insulated
with closed-cell fireproof material.
The heat exchange system is for a 2-pipe plant
and consists of 3 rows of copper pipes with
continuous aluminium fins. The aluminium fin
pack is welded to the pipe surface by mechanical
expansion of the pipes themselves. The frame
is in stainless steel and the collectors in brass
alloy come with female attaching flanges of G 1/
2" and manual air bleed valves of G1/8". The
fan coil unit come as standard with plumbing
attachments on the left side.
The fan system consists of one (sizes 100 and
200) or two centrifugal double-aspiration fans.
They have a high air capacity and low noise level
with blades and screws in plastic. The system
is electronically balanced before and after being
mounted in the unit.
pag. 3
The single-phase 230 V electric motors have a
permanently installed capacitor and heat
protection is incorporated. Use of the
autotransformer means that 6 speeds can be
accessed. Three are standard and can be
selected from the control panel.
The motor is directly coupled to the fan(s) and
mounted on a flexible support and the system is
assembled to include a tray for collection of
condensation. Electrical connection with the
control panel is by rapid polarised insert.
The air filter is made of synthetic fibre and
mounted on a metal frame with a mesh net on
both sides. It can be extracted using the
unblocking flanges and a tool. In the FC and FCR
versions with casing, the air filter is supplied on
request.
The cover (F and FR versions) is made of zinc
plate and pre-painted in colour RAL 9002. It is
protected by transparent cling film to prevent
damage during transportation and installation. G
version are also available with a cover complete
with frontal intake grille in plastic and air filter.
The air output grille comes in modular form in
heat-resistant plastic in colour RAL 7032. The
right and left terminals include the site for the
control panel (F version) and the necessary
access flaps which have an exclusive trip closing
mechanism. In locations where access to the
control panel is not allowed (public places,
schools etc.) the access points can be closed
using the appropriate screw with head cover.
The F version fan heaters come as standard
with space for the control panel on the right
side.
The control panel is not included in the standard
fan heater pack because there are various different
models both for mounting on the appliance and
for remote mounting on a wall:
- Basic control panel 1
consists of an on-off switch for starting and
turning off the fan heater, a manual 3-speed
selector and an 'on' indicator light.
- Basic control panel 2
consists of a manual selector for OFF/
SUMMER/WINTER, a 3-speed manual selector
and an 'on' indicator light.
The control panel is set up for connection of a
thermostat (supplied separately) which means
that in the heating mode the fan is activated
only when the temperature of the water in the
heat exchanger exceeds a pre-set limit.
pag. 4
- Electronic thermostat 1
consists of an on-off switch for starting and
turning off the fan heater, a 3-speed manual
selector, and 'on' indicator light and a manual
SUMMER/WINTER selector.
The thermostat ensures automatic accurate
temperature control in heating and conditioning
plants with 2 pipes. The thermostat regulator
switch enables temperatures of from 5°C to
35°C to be programmed. The fan heater goes
off automatically when the desired temperature is reached.
- Electronic thermostat 2
consists of a manual OFF/SUMMER/WINTER
switch, a 3-speed manual selector and an 'on'
indicator light.
The thermostat includes all the functions of
electronic thermostat 1 and in addition can be
used with a 2-electrovalve control in 4-pipe
plants or 1 electrical resistance electrovalve
in 2-pipe plants. A minimum temperature
reading can also be included using an
appropriate connection (for use in winter
cycle).
- Microprocessor thermostat
Includes all the functions of the electronic
thermostats and in addition has automatic fan
speed selection and summer/winter switch. A
2 electrovalve control is possible in 4-pipe
plants and 1 electrical resistance electrovalve
in 2-pipe plants. A minimum temperature
reading can also be included (for winter use)
and a device for activating the energy saving
function.
1.5 PACK CONTENTS
The fan heaters are supplied as standard in
recyclable cardboard packaging with expanded
polystyrene or pre-shaped cardboard protective
covering.

explosive products are used.
Before proceeding with installation, make sure
that the following conditions apply in the area
where the fan heater is to be installed:
a) that there is a single-phase 230 Volts - 50Hz
electricity supply and that the plumbing
connections correspond to the standard
connections on the left side of the fan heater;
b)that condensation waste pipes can be fitted
efficiently with an adequate slope (minimum
1%) to join up with a siphon connection to the
waste disposal system in the building;
c) that the position allows for the correct
dispersion of air and that air flow is not
obstructed by any obstacles like sills,
furniture, curtains and, on the other hand, that
the air flow does not cause disturbance to
any people present;
d)that the position of the appliance permits
access for maintenance as well as to the
bleed valves attached to the side. Respect
the distances shown in fig. 9. When
installing versions with casing, put in a
removable panel for access to the fan
heater and for its eventual removal.
e)vertical installation units F - FC must be
placed at a height of about 10 cm from the
floor, so that air is collected correctly by the
fan heater. There must be the same distance
between the wall and the back of the appliance
f) when installing horizontally, make sure
that the support surface is of a material
and capacity suitable for supporting the
weight of the appliance. Ensure that the
fixing devices are suitable for keeping
the fan heater stable for a long time.
3.2 INSTALLATION PROCEDURES

to be installed.
3.2.1 Mounting the fan heater
Once the position for the appliance has been
established, mark the four holes to be used for
fixing the unit (fig.11). Use plugs (not supplied)
suitable for the type of support surface (solid
brick, cavity wall, panels etc.).
WARNING! To ensure correct drainage of
condensation into the tray, position the
holes and screws in such a way that the fan
heater is slightly inclined towards the
condensation discharge (about 4mm per
metre is advisable). If this is not done,
The attachments on the exchanger are female
1/2" GAS fillets with external hexagon for a size
26 spanner and are shown in fig.12, with
indications of available space.
Make the connections using spanners and
wrenches but without forcing the pipe
attachment.
Once the pipes have been filled, bleed the air
out by using the bleed valves on the collectors,
using a flat screwdriver or a size 8 hexagonal
spanner on the one in the highest position in
the circuit. Close the bleed valves and check
carefully that there have been no losses at the
various junctions.

microprocessor thermostats), put the
pag. 25
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
= summer,
=
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
Before inserting the new fan system, check 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.

7.3.2 To turn off the heater for a prolonged period:
a) Stop the heat generator or cooling system in
the plant according to the specific instructions.
b) According to the control panel version in use,
turn switch (A) or (B) to the "OFF" position.
c) Disconnect the electric supply from the heater
switch.
7.1 CHECKS
Before starting up the fan heater, make sure the
installer has fully completed all the necessary
installation procedures.
7.2 SWITCHING ON
7.2.1 (references to control panel functions refer
to fig. 14)
a) check that the electricity supply is properly
connected and proceed as follows:
- Version 1 controls
Turn switch (A) to the "ON" position.
If there is one (on the electronic or
microprocessor thermostats) put the
summer/winter switch (B) in the positions
suitable for the cycle in course (pointing up
= summer, down = winter).
- Version 2 controls
Turn switch (B) to the position suitable for
the cycle in course (
= summer,
=
winter).
b) If there is one (on the electronic or
microprocessor thermostats), turn the air temperature thermostat (C) to the temperature
required. The indicator light (E) will show the
function according to the characteristics of
the different control panels.
c) Select the fan speed using (D). If there is a trip
thermostat (optional extra), the fan will start
up only if the internal water temperature in the
exchanger is higher than a pre-determined
level. In this case, wait until the system is
ready.
e) Consult the specific instructions for the actual
control panel in use to see any additional
characteristics and likewise for any optional
accessories which have been installed.
7.3 SWITCHING OFF
7.3.1 7.3.1 When turning off the fan heater, it is
not necessary to touch the temperature control
if there is one, but to proceed as follows:
d) When the system is not used during periods
when there are low outside temperatures,
ensure there is no risk of pipes freezing up by
consulting the installer.
8. MAINTENANCE
8.1
NORMAL MAINTENANCE
PROCEDURES FOR THE USER
WARNING! Any procedure which is not
explicitly mentioned in this chapter should
be carried out by specialised personnel.
8.1.1 Cleaning external parts
The external parts of the heater should be cleaned
at least every two months, always after
disconnecting the electricity supply. Use a damp
cloth and remove any dust from the air outlet with
a brush. WARNING! Do not use water sprays
to clean the appliance.
Check that the fan is working well and that air is
coming out of the air outlet grille correctly.
8.1.2 Cleaning the filter
The air filter should be cleaned before every
operational season, or, if the fan heater is in a
dusty environment, at least once a month.
WARNING! Always disconnect the heater
from the electricity supply and allow the fan
motor to cool before proceeding to remove
the filter.
The following instructions relate to F - FR versions
with covers. For encased versions with their
appropriate panelling, refer to the system used
by the planner and/or installer.
Loosen and extract the filter by turning the fixing
screws on the plastic filter holders and turning
them outwards.
Clean the filter, preferably with compressed air,
by blowing in the opposite direction from the
intake, or use a vacuum cleaner. If necessary,
pag. 28
wash the filter under running water and wait for it
to dry completely before re-insertion.
If the filter material starts to show signs of wear
after a few periodic cleanings, it should be
replaced to ensure fully effective functioning. Do
not throw the old filter away carelessly, but
dispose of it in an appropriate rubbish
container.
8.3 POSSIBLE PROBLEMS
Any repair operations should be carried out
by qualified personnel.
In the case of breakdown, contact the nearest
Service Centre. The name can be obtained
directly from Accorroni S.r.l - Numero Verde 800017089.
Re-insert the filter ensuring that it is correctly
fixed using the holders.
Before seeking assistance, ensure that:
WARNING! Never use the fan heater without
the filter in place as moving parts or parts
under tension and/or at high temperature
would be accessible, especially to children!
There would also be less protection against
dust both for the fan and for the heat
exchanger with a resulting loss of efficiency
in the appliance.
b) the heat generator, cooling system and
regulatory controls in the plant are all working
normally;
8.2
PERIODIC CHECKS ON THE FAN
HEATER
a) the electricity supply is correctly connected;
c) any controls on the appliance (air temperature thermostat, trip thermostat, etc.) are
working normally;
d) there are no obstructions to either air intake or
outlet flow.
In order to reduce possible problems to the
minimum and to keep the fan heater in perfect
working order, thus ensuring maximum efficiency
at the lowest costs, it is advisable to have a
general check carried out by a specialist at
the start of every season of functioning. This
check should include cleaning the heat exchange
system, the fan, the filter and the condensation
tray. The latter should be thoroughly cleaned to
avoid formation of mould or other bacteria where
there is stagnant water.
