PRECAUTIONS FOR USE
y This device is not intended to be used by people (including children) with reduced physical, sensory or mental abilities, or by people
with no experience or knowledge, unless they are supervised or have been given prior instructions on how to use the unit, by a person
responsible for their safety.
y Children should be supervised to ensure that they do not play with the unit.
y Moving the device: before moving the unit, turn it off using the 0/1 button and then disconnect the plug.
y The sheet metal that comprises the chamber and that in the vicinity of it is very hot and can cause burns.
y Caution, this device is an energised electrical device. Persons who do not have electrical authorisation must not dismount or intervene
at the rear of the unit.
MAINTENANCE
BEFORE ANY MAINTENANCE, DISCONNECT THE ELECTRICITY FROM THE UNIT
y Wait until the unit has cooled down before cleaning.
y General information on stainless steel: The words «stainless steel» can be misleading. This is a steel that «resists» corrosion under
certain conditions.
Any type of stainless steel can become corroded:
- austenitic. Example «stainless steel 304» also called 18/10.
- ferritic. Examples: «F17»or «F18TNb».
The resistance to corrosion of stainless steels is linked to the existence of a passive layer of chromium oxide that is reconstituted spon-
taneously in contact with the air. Any phenomenon that is contrary to the creation of this layer can cause corrosion.
It is for this reason that the surface of stainless steel must be periodically cleared of various grime that can be at the origin of a degrada-
tion in terms of the resistance of the passive layer and also ensure that the maintenance steps are properly complied with. (Preparation
for cleaning / cleaning / rinsing / disinfection / rinsing / drying).
Regular maintenance with prolonged rinsing with water is the best way to reconstitute and maintain the passive layer. Each of the steps
linked to maintenance has risks of deteriorating the passive layer: using hard water / overdosing cleaning products / use of chlorinated
detergents / food residue on the products / insufficient rinsing...
For any case of corrosion, the element or the step that is the source of this must be identified.
Recommendations :
- keep stainless steel surfaces clean and dry. Allow the air to circulate.
- clean on a daily basis to remove tarter, grease and all food residue. Corrosion can form under these layers due to a lack of air.
- daily cleaning can be done with a wet cloth. If necessary:
* use soapy water, cleaning products with low chloride content, non-bleach detergents, degreasers for windows.
* remove difficult grime with a non-metal brush (plastic material, natural silk or stainless steel wool).
- do not scratch the surfaces with metals other than stainless steel. In particular, do not use iron brushes.
- fresh rust stains can be removed with gentle abrasive agents or with a fine grade of emery cloth.
- for larger stains, use hot oxalic acid at a concentration of 2-3%. If necessary, treat with nitric acid at a concentration of 10%.
After any treatment, wash with plenty of water and wipe. The use of acid is reserved for those trained and in compliance with
regulations.
Products to be avoided :
- bleach and chlorine derivatives
- hydrochloric acid
- abrasive powders with iron oxide
y Plastic and stratified parts: do not use ethyl alcohol, wine derivatives, bleach, pure, petrol, vinegar, sulphuric, nitric or hydrochloric acid,
etc.
y The interior and exterior of the trolley can be cleaned with a low-pressure stream of water :
- Dismount the air circuit manually by pulling it upwards then towards you once it has shifted.
- Clean the inside of the trolley, the outside and the dismounted parts
- Put the air circuit back in place before reconnecting the electricity.
- Be careful to not strike the fan turbine. The latter could be deteriorated by an impact.
- For the cold models, clean the evaporator with a vacuum cleaner in addition to the low-pressure stream.
