A.4 General safety rules
Protection devices installed on the machine
The guards on the machine are:
•fixed guards (e.g. casings, covers, side panels, etc.), fixed to the machine and/or frame
with screws or quick-release connectors that can only be removed or opened with tools.
Therefore, the user must not remove or tamper with such devices. The Manufacturer
declines any liability for damage due to tampering or their non-use.
Instructions for use and maintenance
•Risks mainly of a mechanical, thermal and electrical nature exist in the machine. Where
possible the risks have been neutralised:
- directly, by means of adequate design solutions.
- indirectly by using guards, protection and safety devices.
•During maintenance, always carried out by personnel qualified, several risks remain, as
these could not be eliminated, and must be neutralised by adopting specific measures and
precautions.
•Do not carry out any checking, cleaning, repair or maintenance operations on moving
parts. Workers must be informed of this prohibition by means of clearly visible signs.
•To ensure the efficiency and correct operation of the machine, periodic maintenance must
be carried out according to the instructions given in this manual.
•Make sure to periodically check correct operation of all the safety devices and the
insulation of electrical cables, which must be replaced if damaged.
•Repair and extraordinary Maintenance must be carried out by specialised and authorised
personnel provided with all the appropriate personal protective equipment, tools, utensils
and ancillary means.
•Never operate the machine, removing, modifying or tampering with the guards, protection
or safety devices.
•Before carrying out any operation on the machine, always consult the manual which gives
the correct procedures and contains important information on safety.
Residual risks
•The machine has several risks that were not completely eliminated from a design
standpoint or with the installation of adequate protection devices. Nevertheless, through
this manual the Manufacturer has taken steps to inform operators of such risks, carefully
indicating the personal protective equipment to be used by them. In order to reduce the
risks, provide for sufficient spaces while installing the unit.
•To ensure these conditions, the areas around the machine must always be:
- kept free of obstacles (e.g. ladders, tools, containers, boxes, etc.);
- clean and dry;
•well lit.
For the Customer's complete information, the residual risks remaining on the machine are
indicated below: such situations are deemed improper and therefore strictly forbidden.

•placing in the machine any objects or things not compatible with its use, or that can
damage it, cause injury or pollute the environment;
•climbing on the machine;
•non-compliance with the requirements for correct machine use;
•other actions that give rise to risks not eliminable by the Manufacturer.
The previously described actions are prohibited!
Machine cleaning and maintenance
IMPORTANT
The oven must be maintained and cleaned to ensure correct operation and safety.
•Before carrying out any cleaning or maintenance, disconnect the hood and the oven from
the power supply. For details, see par. Electrical Connection in the Installation Manual.
•Do not touch the appliance with wet hands or feet or when barefoot.
•Do not remove the safety guards.

operations. Non-compliance with the instructions can create risks for personnel.
Preventive maintenance
•Preventive maintenance reduces downtimes and maximises machine efficiency. Customer
Care can provide advice on the best maintenance plan to be purchased based on the
intensity of use and the age of the equipment.
Repair and extraordinary maintenance
•Repair and extraordinary maintenance must be carried out by specialised and authorised
personnel. The manufacturer declines any liability for failures or damage due to work
carried out by technicians not authorised by the Manufacturer, and such work will void the
warranty.

231007 OM_HO_04_ELUX_EN.docx - 16
F.2 Appliance cleaning
The oven has special cleaning programs; a pop-up
window automatically appears when maintenance is
required.
NOTE!
To ensure best cleaning results, and to
protect the hood with the cleaning
programs, neutral detergents must be
used.
F.2.1 Labyrinth Filters cleaning
The labyrinth filters are located in front of the hood.
Periodic cleaning is recommended.
1. Remove the labyrinth filters, starting from the
middle one, raising (1) and pulling the lower part
outwards (2);
2. Wash with hot water and neutral detergent
using a nozzle; if necessary, use a soft brush or
place it in a dishwasher and select a gentle
program.
3. Rinse in hot water, shake well and allow to
drain.
4. Refit the labyrinth filters. Make sure to refit them
properly.
F.2.2 External and internal cleaning
•Clean the stainless-steel parts every day using
lukewarm soapy water;
•Rinse with plenty of water and dry thoroughly;
•Do not clean the stainless steel with steel wool,
brushes or scrapers in common steel, as they
could deposit ferrous particles which oxidise,
causing rust spots;
•Whenever the appliance is not used for long
periods:
- Disconnect the power supply. Turn off the
water taps;
- Go over all steel surfaces vigorously with a
cloth moistened with paraffin oil in order to
create a protective film;
- Periodically air the premises.
F.2.3 Demister and Water Separator Filter
cleaning
