SECTION A - GENERAL INFORMATION
1.PRINCIPALCHARACTERISTICS
1.1 APPLIANCE CLASSIFICATION
The F-FR-FC-FCR fan heaters are defined as
"air treatment terminals for winter and summer
airconditioning".
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
airistakeninbythefansandsentouttotheheat
exchanger which heats the air in winter or cools
it in summer. During the summer cycle,
dependingontheheat-hygrometricconditionsof
the outside air, water condensation is formed
andcollectedintheappropriatecontainersothat
it can be disposed of.
The treated air is emitted through the appliance
grilleorthroughtheoutletunitsbuiltintotheplant.
The appliances come as standard with fittings
for2pipes. For4-pipeplantswithtwoindependent
circuits,thereisanoptionalsupplementaryheat
exchangesystem. Thefan heaterhasa remote
control (supplied separately). A choice can be
made from various available versions.
1.4 ASSEMBLY CHARACTERISTICS
1.4.1 Available versions
Thefanheatersareavailablein6differentsizes
and in the following versions:
FR- Vertical with casing
For wall installation, under windows or in
anyotherfreespaceorpositionwhichoffers
technical or functional advantages.
FC- Horizontal with casing
Fordirectceilinginstallationinallsituations
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
invisibleinstallation inpanellingordropped
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
wallorceilingwithhooksandbracketsaswellas
mountings for the various components and
accessories. Internal surfaces are insulated
with closed-cell fireproof material.
Theheatexchangesystemisfora2-pipeplant
and consists of 3 rows of copper pipes with
continuous aluminium fins. The aluminium fin
packisweldedtothepipesurfacebymechanical
expansion of the pipes themselves. The frame
is in stainless steel and the collectors in brass
alloycomewithfemaleattachingflangesof G1/
2" and manual air bleed valves of G1/8". The
fancoilunitcomeasstandardwithplumbing
attachments on the left side.
The fan system consists of one (sizes 100 and
200) or two centrifugal double-aspiration fans.
Theyhaveahighaircapacityandlownoiselevel
with blades and screws in plastic. The system
iselectronicallybalancedbeforeandafterbeing
mounted in the unit.

pag. 4
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
mountedonaflexible support and thesystemis
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
unblockingflangesandatool. IntheFCandFCR
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
damageduringtransportationandinstallation. G
versionare alsoavailablewithacovercomplete
with frontal intake grille in plastic and air filter.
The air output grille comesinmodularform 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
accessflapswhichhaveanexclusivetripclosing
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.
Thecontrolpanelisnotincludedinthestandard
fanheaterpackbecausetherearevariousdifferent
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,a3-speedmanualselector
and an 'on' indicator light.
The control panel is set up for connection of a
thermostat(suppliedseparately)whichmeans
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.
- 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/WINTERselector.
The thermostat ensures automatic accurate
temperaturecontrolinheatingandconditioning
plants with 2 pipes. The thermostat regulator
switch enables temperatures of from 5°C to
35°Ctobe programmed. Thefanheater goes
offautomaticallywhen the desiredtemperatu-
re is reached.
- Electronic thermostat 2
consistsofamanualOFF/SUMMER/WINTER
switch, a 3-speed manual selector and an 'on'
indicatorlight.
The thermostat includes all the functions of
electronicthermostat1andinadditioncanbe
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
speedselectionand 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

recyclablecardboardpackagingwithexpanded
polystyreneorpre-shapedcardboardprotective
covering.
The pack contains this manual of technical
installation procedures, use and maintenance
as well as plastic fittings and screws for fixing
the filters in versions F-FR with covers.
