General information

The aspiration hoods allow eliminating fumes and the odours of cooking from the

kitchen through a dedicated disposal conduit, drawing in clean air, substituting the

expelled air by opening the kitchen air replacement unit.

This action is generated by the aspiration group in the hood that removes the air under

the hood and conducts it outside through the disposal conduit. Moreover, the hood

includes the aspiration function commands and a functional system of illumination of the

cooking top. Expert installation of the hood and timely maintenance allows greater

maintenance, over time, of the services while fully respecting safety regulations.

Verifications

Before proceeding with interventions considered “Repairs”, check that the

“Verification” operations of small faults or disturbances have been carried

out.

Unusual noise or vibrations

 Check the tightness of the installation screws

 Check the correct closure of the perimeter panel

The hood does not start

 Check the insertion of the supply plug

 Check that there has not been interruptions in the power supply

 Check the position of the motor command

Scarce aspiration

 Wash the metal filters or change the active carbon filters in the hood in the

filtering version

 Check that the air exit tubing is not obstructed and that it is of the correct

dimension

7

9 1. Light fixture: available and different in form and dimension in all F-Light

models with the exception of the Zoom model. The 6 lamps must be powered

separately from the hood and driven by the wall light switch of the kitchen.

9 2. Lighting group: it lights the hob with 4 X 20W halogen spotlights, operated

by the control group on board or by the remote control.

9 3. Control group: it turns on and off the lights, drives the hood motor and the

up&down movement of the hood body.

9 4. Suction area: the hood uses the perimetric aspiration principle, defined by the

lighting group. Inside there is the self supporting metal grease filter.

9 5. Fumes exit hole: it can be used both for the recirculating and the exhausting

installations.

Procedure for repair interventions

We advise following this intervention schedule:

 Visual analysis of the product and evaluation of its installation.

 Identifying the problem and changing eventual defective parts.

 Performing functional tests designed to evaluate the correctness of the

intervention carried out.

 Issuing a document that, other than the details of the client, shows the type of

intervention carried out and the eventual list of spare parts used.

Preliminary operations

Disconnect the hood

 Remove the electric plug connecting to the power

 Switch off the main electrical power switch

Remove the perimeter aspiration panel

 To make the internal parts of the hood accessible

Remove the grease filters

 To access to the functional parts of the hood

Remove the anti-odour filters

 If the hood is installed in the filtering version

Interventions on the appliance

The interventions on the appliance, whenever possible, can be executed both on the

installed hood or after dismounting it from the roof fixed support plate. The technician

will choose the operating way.

In order to dismount the hood body it is convenient to place a proper support (i.e.:

carton box, chair,...) over the cooking area: after releasing the four steel ropes the hood

body could be placed on this support, providing easy access to its top panel and proper

protection to the cooking area.

Here below we describe the procedure to disassemble each steel rope:

It is not needed to remove the hood body from the roof fixed support plate in order to

operate on the halogen lights, the fuse, the lighting group and the control group.

The hood body might be removed from the support plate in order to operate on the

motor group, electronic main board, up&down motion group, halogen lights

transformer, up&down motor transformer.

9 Unscrew the safety nut “1”

9 Push up the threaded pin “2” inside the

cylinder “3” and keep it in position, to

unlock the rope

9 Pull the rope “4” in order to extract it

completely from the locking system

9 Note that normally the cylinder “3” is

completely screwed in the support and

there is no need to unscrew it in order to

remove the rope

9 WARNING: after the installation, tighten

very well the safety nut “1” in order to

avoid, for the future, the misalignment of

the hood, hence the fault of the up/down

movement

10

In order to open the top cover of the hood body, remove the 4 screws and the power

supply cable holder:

The picture shows the inside of the hood body after the removal of the top cover:

GEAR MOTOR: it operates the winding and unwinding of the pulleys hosting the steel

ropes that support the hood body . The 12 Volts toroidal transformer hosted in the

electronic mother board group provides the power supply to the gear motor.

LOWER POSITION MICRO SWITCH: controls the down movement and it is

activated when the hood reaches the height set at installation.

UPPER POSITION MICRO SWITCH: controls the rise of the hood and it is

activated when the hood reaches the pin fixed on the roof support plate.

HORIZONTAL POSITION MICRO SWITCH: monitor the correct horizontal

position of the hood body: it disables the up&down movement in case of significant tilt

of the hood body itself. In this case the hood is kept in fixed position, seemingly unable

to receive input from the remote controls, while other controls, i.e.: lights and airflow

motor, are normally drivable. The malfunction is highlighted by the fast flashing of the

led on the control group.

includes the main board, the electronic transformer for the 4 halogen lights and the

toroidal transformer for the up&down movement gear motor.

Motion Group:

remove the 10 screws to release the up&down motion group from the

hood body. Disconnect the 12V supply connector and remove the 4 ropes from the

pulleys. The motion group is supplied as a completed assembled spare part in order to

avoid misalignments of the pulleys and chains on the zinc supports.

Motor:

the motor group is fixed on the hood body top with the 4 screws shown below.

However it must be removed from the lower part; hence it is necessary to open the

lighting group, remove the metal filter and disconnect the power supply connector on the

left and the main board wiring connector on the right of the motor group.

After the opening of the lighting group panel it is necessary to remove the stainless steel

cover to reach the controls and the lighting:

Note that this stainless steel cover was introduced in production on January 2011 (Prod.

1102). Hence it will not be found on the hoods produced before the end of 2010.

Fuse

: it protects the mother board in relation to the up&down movement. Open the

lighting group to reach the fuse holder, which is located on the left for productions

within 1031 and on the right for productions from 1032. Unscrew the fuse holder to

reach the fuse.

In the models equipped with light fixture (all except “Zoom” model) the lamps (halogen

or energy saving) are mounted on the roof fixed support plate.

It is needed a 220V power supply separated from the hood one. Hence for these models

two separated 220V power supply are needed.
