MAINTENANCE INSTRUCTIONS
CAUTION
DISCONNECT THE POWER SUPPLY BEFORE SERVICING OR CLEANING THIS OVEN.
SAFEGUARD THE POWER SO IT CANNOT BE ACCIDENTALLY RESTORED. FAILURE
TO DO SO COULD RESULT IN DISMEMBERMENT, ELECTROCUTION, OR FATAL INJURY.
THERE IS MORE THAN ONE POWER SUPPLY CONNECTION POINT WHEN OVENS ARE
STACKED, SO MAKE SURE THAT ALL SWITCHES ARE IN THE OFF POSITION BEFORE
CLEANING OR MAINTENANCE.
No electrical components should be subjected to moisture. It is therefore important that the
oven is wiped down carefully. NEVER throw buckets of water over the oven or subject it to
pressure washing from a hose or a pressure spray. If water or other liquid is spilled on the
oven, make sure that none of it has entered the control box area before switching the oven
ON. If in doubt, call your service company.
CAUTION

1. The oven must be cool. Do not use power cleaning equipment, steel wool, or wire brushes
on stainless steel surfaces.
2. Do not use a caustic or an alkaline base cleaner on the interior of the oven. This will ruin
the aluminized fi nish of the oven interior.
