MAINTENANCE
WARNING
NEVER ATTEMPT TO CLEAN OR SERVICE THIS OVEN UNTIL IT HAS BEEN
DISCONNECTED FROM THE POWER SUPPLY AND IS COOL TO THE TOUCH.
NOTE
REMEMBER A CLEAN OVEN WILL LAST LONGER AND WORK BETTER.
Cleaning
The outside of the oven should be cleaned daily by wiping it with a clean damp cloth or
by using any suitable stainless steel cleaner. A solution made up of a mild detergent
with water will normally be sufficient for routine cleaning of the interior of the oven.
When finished dry the surfaces with a clean cloth.
The glass door should be cleaned daily using normal glass cleaners.
For more difficult cleaning jobs such as where there are burned on or greasy deposits, or
heat tint, you should use an abrasive pad. Remember for best results always keep the
stainless steel shiny.
To simplify major cleanings the inner liner may be removed by first removing the nozzle
assembly in the back of the oven with an open end wrench, and then by removing the
eight slotted head screws which secure the liner. Six of these screws are in the front of
the oven while two additional screws are on the rear panel adjacent to the nozzle
assembly.
Clean the rear fan cover frequently to insure air circulation through the electrical
compartment. This will lessen the possibility of heat related electrical problems.
The heating elements themselves normally do not require cleaning.
Lubrication
Occasionally put a few drops of oil on the pivot points of the door. No other items
requires lubrication.
CAUTION
NEVER LUBRICATE THE MOTORS
