CLEANING THE CAVITY GASKET
In order to remove traces of grease or food scraps that can damage the gasket, regular and manual cleaning of the cavity gasket should be
performed on the inner and outer faces. Before cleaning, use water with soap or neutral and non-abrasive detergent with a sponge or a soft cloth to
remove the grease from the cavity gasket.
17.5
MAINTENANCE OF INTERNAL SURFACES
The general principle consists in not letting the following settle in certain places:
- Substances likely to become concentrated and so become corrosive.
- Settling of different minerals contained in water and likely to generate corrosion (walls) performance and life-duration (fan balancing,
exchanger dissipation, ..) problems.
A trolley or preheating plate (optional) must be used for the automatic wash cycle on 20 level ovens.
CLEANING, DEGREASING: Once a day (see section « Cleaning menu »)
DESCALING: Every day if necessary.
If there are any mineral deposits (whitish specks) as a result of un-softened water in the cooking chamber this must be removed daily.
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.
