For maximum efficiency of the descaling product without damaging the material and components of the oven, you should use an
appropriate descaler. The use of certain acids has an irreversible destructive effect that may cause significant damage. The
descaling product must contain corrosion inhibitors to prevent metal attack. It must also comply with legal requirements, in
particular for material intended to come into contact with foodstuffs.
Chemical products containing nitric acid are strictly prohibited. Recommended composition:
- Phosphoric acid <50%
- Corrosion inhibitor
Procedure:
Before descaling the cooking cavity, a cleaning cycle is required (see paragraph « Cleaning menu ») to dissolve any accumulated grease.
Manual descale:
- Run in steam mode at 60°C for 5 minutes
- Manually spray the surfaces to be treated with a descaling product specifically adapted for use on stainless steel thus the
composition recommended is : phosphoric acid with a concentration of less than 50% + tensio- active corrosion inhibitors, diluted to
a known level (conforming to the product label and its data sheet) and using suitable protective equipment (conforming to the product
hazard sheet).Thoroughly spray the areas with limescale deposits (Fans, elements, panelling).
- Leave the product to act for several minutes depending on the level of scaling.
- Rinse using the automatic rinse cycle (see paragraph « Cleaning menu »).
- Undertake a cleaning cycle (see paragraph « Cleaning menu »)
The optional automatic cleaning system is designed to introduce degreasing detergent and nothing else. Never use a descaling solution. This
could cause irreversible damage to your oven.
15.6 MAINTENANCE OF THE STEAM BOILER
(Equajet boiler)
Boiler maintenance takes place out of hours during the oven cleaning. During this operation the generator will be rinsed to get rid of any steam
and calcium deposits in suspension in the water prior to descaling. The drain pipe work will be cleaned of grease and cooking juices. It is normal for
water to rise slightly into the bottom of the oven in order to clean the drain outlet.
15.7 MATERIAL USED FOR COOKING CORROSIVE PRODUCTS
(Sea fish, sauerkraut)
The materials used intensively and regularly for cooking corrosive products, such as sea fish, sauerkraut, …, should be cleaned carefully and
systematically after each use.

the cleaning
Check the valve and water pressure.
If the message appears during a cleaning cycle it is
possible to stop the cycle if the cleaning chemicals have
not yet been injected, by pressing stop. Check that the
