If the temperature control is not functioning 100%, switch the appliance off immediately.
Remove the appliance’s main fuse. Do not use the appliance if damaged in any way.
When putting oil, fat, water or ingredients in the preheated hot frying pan, they may spit.
This action must therefore be carried out by the appliance operator with due care.
Overheated fats and oils ignite quickly in the hot frying pan. Always take care when cooking with fats
and oils.
The appliance must not be used for deep frying.
The use of corrosive, poisonous and inflammable substances in our cooking appliances is strictly forbidden.
After pressure cooking, cooking with a closed lid or pressure cooking in the oven itself, activate the
pressure release function before taking any other action.
After cooking with the lid closed either without pressure or with a low residual excess pressure the lid
must not be opened until the appliance has expelled all the pressure.
Practise particular caution if the food is bubbling. If the lid is opened with a slight residual excess pressure,
hot food may pour out and injure the operating staff.
Pay particular attention to simmer-delay. Simmer delay is the name of the phenomenon that under certain
conditions (e.g. on high mountains or plateaux where the air pressure is lower that at sea level) liquids can
boil at lower than 100°C and therefore can be heated beyond their boiling point without them simmering,
boiling or bubbling. This situation is dangerous because the slightest movement can quickly cause a large
steam or gas bubble to form that can then explode out of the cooking pot.
Our appliances are partially thermally insulated and insulated. The temperatures required for the
cooking processes in industrial cooking appliances, depending on the function principle, means that
various parts (e.g. cover areas, cladding panels etc.) can get hot. This is not a design fault but caused
by the physical phenomenon that stainless steel conducts heat.
Do not spray the appliance with water, steam or high pressure cleaners and do not pour water over it.
This appliance is not intended to be used by children and people with restricted physical, sensory and
mental faculties or who have a lack of experience and/or knowledge unless they are supervised by a
person responsible for their safety or have received instructions from this person on how the appliance
is to be used.
1.4.6 Handling industrial cooking appliances
The built-in stainless steel components for industrial cooking are made of high-quality and approved materials.
The sum of their positive characteristics makes them ideal materials for use in food preparation.
The reason the anti-rust stainless steel can resist corrosion is a passive layer which builds up when oxygen hits the metal
surface. There is sufficient oxygen in the air to do this.
If this passive layer is damaged by mechanical effects or damaged chemically and the passive layer is prevented from
regenerating itself (lack of oxygen) even rust-free stainless steel may corrode. It is possible to develop or regenerate the
passivity by treating it with running oxygen-rich water. Degenerative (oxygen starving) abrasives, such as substances
containing hydrochloric acid, chlorides and spice concentrates, mustard, vinegar essences, spice cubes and cooking salt
solutions can cause chemical damage or destruction of the passive layer depending on the concentration and the
temperature. In addition, damage may occur: due to external rust (small iron parts) due to the build up of galvanised
elements and through lack of oxygen (no ventilation or low-oxygen water).
Note, therefore, the following principles when working with stainless steel appliances:
Keep stainless steel surfaces clean at all times and make sure they are well ventilated. Do not place the
lid on appliances when not in use so that air can get to the surface. Regularly wipe away any build-up of
lime scale, grease, flour and egg white. A layer of any of these substances can encourage corrosion by
starving the surface of air. Descaling can be carried out with a solution of 10% vinegar, 10% phosphoric
acid or a suitable commercially available descaling agent.
Do not let stainless steel parts come into prolonged contact with acids, spices, salts, etc. Even acid
fumes which build up from cleaning tiled surfaces can promote corrosion. Rinse off work surfaces with
fresh water. This applies especially after cooking potatoes, pasta or rice in salted water. Dried-up
cooking water creates a highly concentrated salt solution which can quickly cause corrosion. For this
reason, rinse cookware immediately after use with fresh water or fill with cold water and leave to cool
down. It is uneconomical to use an appliance solely for the purpose of, for example, boiling potatoes
in salted water. Instead, with stainless steel it is sensible to fill the appliance with various types of food,
e.g. with soups with a high fat content or acidic vegetables (such as pickled cabbage).
Avoid physical damage to the stainless steel surface, especially with other metals. If stainless steel
comes into contact with iron (wire wool, swarf from cables, iron-rich water) this can lead to corrosion.
Remove fresh rust with a mild souring agent or fine abrasive paper. Wash away stubborn rust with a
warm 2-5% oxalic acid solution.
If these cleaning agents do not work, treat the rust with 10% nitric acid.
Because of the risk involved, this treatment may only be applied by technically trained staff in
accordance with the applicable guidelines.
