Initial start-up
8 / 85
During initial start-up of your new device, you will be requested to start an automatic self-
test. This self-test takes about 45 minutes and is used to adapt the device to the specific
environmental conditions. Please note the following:
- For the self-test to be carried out, all the packaging materials must have been removed
from the device; check the grid shelves and the air baffle for a correct fit.
- The device must be connected in accordance with the installation instructions.
- For unit size 6x1/1, 10x1/1, 6x2/1 and 10x2/1 GN, place a flat GN container with the
opening facing downwards in the centre of the grid shelves.
- For unit size 20x1/1 and 20x2/1 GN place two GN-containers in the mobile oven rack.
Place one flat container with the opening facing downwards in the centre in front of both
the upper and lower fan wheel.
Risk of fire!
Remove the packaging material, starter kit as well as grids and containers.

The cooking cabinet door must not be opened during the self-test. Opening the cooking cabinet
door will lead to failure of the self-test. Restart the self-test by switching the device off. Always
allow a hot device to cool down first. If the test is interrupted you will be requested next day by
the device to start the self-test again.

Safety instructions and liability
14 / 85
Liability
Installations and repairs that are not carried out by authorised specialists or using genuine
spare parts, and any technical change that is not approved by the manufacturer will invalidate
the manufacturer’s warranty and product liability.

Care, inspection, maintenance and repair
15 / 85
Your unit must be cleaned every day or when a request for cleaning appears to maintain the
high quality of the stainless steel, for hygiene reasons and to avoid operating faults. To do
this, follow the instructions in the “Efficient CareControl” section.
Continuous operation at high cooking cabinet temperatures (≥260°C) or the use of high
browning levels (brown 4/5) and a production with predominantly high-fat and gelatin-
containing foods may lead to more rapid wear of the door seal.
Daily cleaning of the cooking cabinet seal with a non-abrasive cleaning agent will extend the
service life.
Warning!
If the unit is not cleaned or is not cleaned well enough, deposits of grease and/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 unit must be cleaned every day, even if it
is only operated in “moist heat” (steaming) mode.
-Apply vegetable oil or grease to the inside of the cooking cabinet at regular intervals (every
2 weeks or so) to prevent corrosion.
-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.
-The unit must not be cleaned with high pressure cleaner, steam cleaner or a direct water
jet.
-Do not treat the unit with acids or expose to acid fumes since this will damage the
passivated coating of the nickel-chromium steel and the unit might discolour.
-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
is not covered under warranty.
-Do not use scouring products or scratchy cleaning agents.
