before moving the oven.
When all cleaning and servicing is complete:

or service the oven, reconnect it at this time.

WARNING
Possibility of injury from rotating parts and
electrical shock exist in this oven. Switch off
and lockout/tagout the electric supply BEFORE
beginning to disassemble, clean, or service any
oven. Never disassemble or clean an oven with
the ON/OFF switch, I/O switch, or any other
circuit of the oven switched on.
NOTICE
NEVER use a water hose or pressurized steam-
cleaning equipment when cleaning this oven. To avoid
saturating the oven insulation, DO NOT use excessive
amounts of water. DO NOT use a caustic oven
cleaner, which can damage the bake chamber
surfaces.
NOTICE
ANY replacement parts that require access to the
interior of the oven may ONLY be replaced by a
Middleby Marshall Authorized Service Agent. It is also
strongly recommended that the 3-Month Maintenance
and 6-Month Maintenance procedures in this section
be performed ONLY by a Middleby Marshall
Authorized Service Agent.
