Installation facilities (accessories)
The oven can be placed on the floor or on a
bench (working surface). It is important that
the oven is set up accurately horizontally; the
door may have to be adjusted
(see Section:
„Maintenance“)
The spacing from the back of the oven to the
wall should be at least 15 cm. The spacing to
the ceiling must not be less than 20 cm and
that at the side to the wall not less than 8 cm.
Generally it is essential to have adequate air
ventilation around the oven.
Information on accessories will be found in our leaflet or on our internet page www.memmert.com.
