1. Safety
Danger!
Repairs may only be carried out by a qualified electrician! Inexpert repairs may
lead to risks and damages for the user!
To prevent electric shocks, please observe the following tips:
• In the event of faults, housing and frame may be live!
• Touching live components inside the appliance may cause dangerous currents to flow through your
body!
• Prior to repairs, disconnect the appliance from the mains!
• When inspecting live parts, a residual current operated device must be used at all times!
• The ground wire resistance must not exceed that specified in the standard! It is of vital importance
for ensuring the safety of people and the functioning of the appliance.
• On completion of repairs, an inspection must be carried out in accordance with VDE 0701
[Association of German Electrical Engineers] or the corresponding regulations for your country!
• On completion of repairs, a function and impermeability inspection must be carried out.
Caution!
Make sure you observe the following instructions:
• The appliances must be disconnected from the mains prior to all repairs. If inspections must be
carried out on live appliances, make sure you use a residual current operated device.
Sharp edges: Use protective gloves.
Components may be electrostatic!
Observe handling precautions!

2. General
Depressurised steam cooking involves cooking food with a combination of steam and hot air. Gentle
steam cooking at temperatures of between 40°C – 100°C optimally preserves vitamins and minerals as
well as maintaining colours and natural aromas. Food does not dry out and nor will it burn or stick.
Since only a relatively small amount of water needs to be heated, steam cooking means that a great deal
of time and energy can be saved.
Depressurised steam cooking takes place at temperatures of between 40 °C and 100 °C, thus making it
easy to cook food just as it is required. The climatic sensor steams the food in just the right conditions,
irrespective of the quantity of food being cooked. Instead of being destroyed, vitamins and minerals are
largely preserved. Flavour, colour and consistency are maintained – food does not lose its structure.
There is therefore almost no need to add salt and spices.
To sum up: cooking with steam makes conscious, healthy eating possible without any extra effort. The
steam cooker provides excellent possibilities in combination with the ökotherm®cooker or oven.
It is particularly when meat is being cooked that the oven becomes dirty due to squirting juices. Dirt which
has become dried can be removed more easily if the cooker, prior to cleaning, is operated with the
“steam” cooking mode at a temperature of 100 °C for approximately 30 minutes, thus softening any
soiling. After being used for some time the oven will take on a golden colour.
