WEEKLY CLEANING
Regularly clean the back vents of the oven of dust and
grease. Be sure the oven has cooled down and the fans are
not running. Use a damp towel. If the cooling vents are
blocked, the oven could malfunction.

Regularly check that the wall clearances are sufficient
otherwise damage to the appliance and surroundings may
occur. Do not store anything directly on the oven.
Keep at least 15 cm distances from heat sources, like a
grill or other heating appliances. Keep at least 102mm
space on the left and right sides, and 300mm clearance
from the back. An optional Alto-Shaam heat shield can be
used in the back to reduce the rear clearance requirement
to 0mm.
Failing to do so will void warranty and cause premature
failure of components. Please refer to the instruction
manual.

Clean the front of the oven the same way. Be sure the
contact area between door and oven front is always clean
and free of debris. Build up of particles in this area can
cause the oven to malfunction.

Wipe the inside of the baking chamber as the detergent
has soaked in. Rinse surfaces by wiping with a sponge and
clean warm water.
