Safety instructions and liability
14 / 112
Liability
Installations and repairs that are not carried out by authorised specialists or using original
spare parts, and any technical modification that is not approved by the manufacturer will void
the manufacturer’s warranty and product liability.
Care, inspection, maintenance and repair
15 / 112
In order to retain the high quality of the stainless steel, for hygienic reasons and to avoid
interferences to operation, the appliance must be cleaned daily or when prompted to clean.
Follow the instructions in the "Cleaning" section.
Constant operation at high cooking cabinet temperatures (≥ 260°C), the use of high browning
levels (browning 4/5) and preparation of food with high fat and gelatin content can subject
the press-fit door gasket to faster wear.
Cleaning the press-fit door gasket daily with a non-abrasive rinsing agent will extend the
service life.
Warning!
If the appliance is not cleaned or is not cleaned well enough, deposits of grease or
food residues in the cooking cabinet may catch fire - Risk of fire.
- If fat deposits and/or food waste in the cooking cabinet ignite, shut down the appliance
immediately and keep the cooking cabinet door closed to put out the fire! If further
extinguishing is required, disconnect the appliance from the mains and use a fire
extinguisher (do not use water to extinguish a fat fire!).
- To avoid corrosion in the cooking cabinet, your appliance must be cleaned every day, even
if it is only operated in “Moist Heat” (steaming) mode.
- Do not use a high pressure cleaner, steam cleaner or a direct water jet to clean the
appliance. Observe the protection class IPx5.
- Do not treat the appliance with acids or expose to acid fumes – this will damage the
passivated coating of the nickel-chromium steel and the appliances might discolour.
- To clean the exterior panelling, only use mild household cleaning agents such as
dishwashing detergent on a damp soft cloth. Corrosive or irritating substances must not
be used.
- Only use cleaning agents from the appliance manufacturer. Cleaning agents from other
manufacturers can damage the appliance. Damage to a device that has been caused by
using different cleaning and care products than those recommended by the manufacturer
