CAUTION

NEVER use a water hose, water jet, or pressurized steam-cleaning equipment when cleaning this oven. DO NOT use excessive amounts of water, to avoid saturating the oven insulation. DO NOT use a caustic oven cleaner, which can damage the aluminized bake chamber surfaces.

NOTE

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.

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 the outside of the oven with a soft cloth and mild detergent.

C.Clean ALL of the cooling fan grills and vent openings with a stiff nylon brush.

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. Be sure to replace the

trays in the same positions from which they were removed,
