I. MAINTENANCE - DAILY
A. Check that the oven is cool and the power is disconnected,
as described in the warning at the beginning of this Section.
B. Clean ALL of the cooling fan grills and vent openings with a
stiff nylon brush. Refer to Figure 4-1 for the locations of the
grills and vents.
C. Clean the outside of the oven with a soft cloth and mild
detergent.
D. Check that ALL cooling fans are operating properly.
CAUTION
If a cooling fan is not operating correctly, it must be replaced
IMMEDIATELY. Operating the oven without adequate
cooling can seriously damage the oven's internal compo-
nents.
E. Clean the conveyor belts with a stiff nylon brush. This is
more easily accomplished by allowing the conveyor to run
while you stand at the exit end of the conveyor. Then, brush
the crumbs off the conveyor as it moves.
F. Remove and clean the crumb trays. If necessary, refer to
Figure 2-13 (in Section 2, Installation) when replacing the
crumb trays into the oven.
G. Clean the window in place.

WARNING
Possibility of injury from moving parts and electrical shock exists 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
BLOWER ( ) switch or any other circuit of the oven switched on.
CAUTION
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.

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.
