CLEANING
BEFORE ALL CLEANING UNPLUG THE APPLIANCE FROM THE ELECTRIC SUPPLY
y Wait until the unit has cooled down before cleaning.
y Only the inside of the compartments can be cleaned with a low pressure stream.
y Cleaning the condenser: the condenser has to be cleaner by an after-sales service department.
y Clean the evaporator :
- remove the front sheet metal: CAUTION on models without a sneeze-guard, remove the sheet metal carefully without pulling too hard in
order to avoid damaging the power cable of the touchscreen case.
- remove the stainless steel box located to the right of the evaporator by pulling on it.
- clean the evaporator with a vacuum cleaner or low-pressure stream.
y Cleaning the condensate tray : the tray is situated under the trolley, to remove it loosen the screws to release the tray.
y General information on stainless steel : The term "stainless steel" can cause some confusion. It is steel which "resists" to corrosion in
certain conditions.
Any type of stainless steel can be corroded:
- austenitic, e.g. "stainless steel 304" also called 18/10.
- ferritic, e.g. "F17" or "F18TNb".
Resistance to corrosion of stainless steel results from the existence of a passive layer of chromium oxide which is renewed spontaneously
when in contact with the air. Any phenomenon interfering with the creation of this layer is likely to cause corrosion. This is why stainless
steel surfaces must be regularly rid of miscellaneous contamination which may damage the level of resistance of the passive layer, and also
ensure the maintenance steps are observed. (Preparation to cleaning / cleaning / rinsing / disinfection / rinsing / drying).
Regular maintenance with extended rinsing with water is the best method to renew and maintain the passive layer.
Each of the steps linked with maintenance presents risks of damaging the passive layer: using hard water / overdosing detergents / using
chlorine-based detergents / food residue on the products / insufficient rinsing.....
Whenever corrosion appears, the element or step having led to it must be identified.
Advice :
- maintain stainless steel surfaces clean and dry. Ensure there is a sufficient flow of air.
- clean daily to remove scale, grease and any food residue. Corrosion can form under these layers by lack of air inlet.
- daily cleaning can be performed with a damp cloth. If necessary :
* use soapy water, cleaning products with low chloride content, javel-free detergents, window degreasers.
* remove hard stains with a non metallic brush (plastic material, natural bristles or stainless steel wool).
- do not scratch the surfaces with metals other than stainless steel, and more particularly, never use iron brushes.
- remove fresh rust stains with soft abrasive agents or fine emery cloth.
- for larger stains, use hot oxalic acid with a 2-3% concentration. If necessary, apply a treatment with nitric acid concentrated at 10%.
After treatment, wash thoroughly with water and wipe.
The use of acid is reserved to skilled persons and complying with regulations.
Product to ban :
- Javel water and chlorine based products
- hydrochloric acid
- iron oxide abrasive powders..
- Stratified and plastic parts: do not use ethyl alcohol, wine derivatives, pure sodium hypochlorite, petrol, vinegar, sulphuric, nitric or hydro-
chloric acid, etc...
