21. After cooking ends the electric fan will continue running for a certain period of time to
cool down the cavity.
22. The steam oven and its parts should be kept clean. Failure to do so will result in
deterioration of the appliance surface and aect its life cycle. It may also cause danger.
23. Remove the power supply plug before cleaning. Do not use corrosive cleaners as they
may cause damage or corrosion.
24. Water in the water tank will be heated up and discharged to the drip tray during
“Descaling Mode”. Do not allow children to touch or go near the steam oven.

hazard to the user. Do not use the appliance if the door is warped, the door hinges are
loose or holes or cracks are visible in the casing, the door, the door seal, or the oven
interior walls.
34. The electrical safety of this appliance can only be guaranteed when continuity is
complete between it and an eective earthing system. It is most important that this
basic safety requirement is present and tested regularly and, where there is any doubt,
the household wiring system should be inspected by a qualified electrician.
35. Before connecting the appliance to the power supply, make sure that the rating on the
data plate (voltage and frequency) corresponds to that of the household supply. This
data must correspond in order to avoid risk of damage to the appliance. Consult a

dishes, such as meat, seafood,
pizzas, bread, cookies, pastries
and desserts.
Combi mode combines high
steam cooking, upper &lower
heating elements and the
convection fan all at the same
time. Adding steam during the
cooking process can prevent
moisture loss during high-
temperature cooking. This
mode is suitable for cooking
all types of food.
