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. 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 the front cooling fans, as follows:

•Snap off the protective grille, and wipe it clean with a cloth. See Figure 3-1.

•Remove the foam filter and inspect it. If it is dusty, shake it briskly. If dirt or grease is present on the filter, wash it in warm, soapy water. Rinse the filter, squeeze it to remove as much of the water as possible, and then set it aside to dry thoroughly before reinstallation.

•Once the filter is dry, reinstall the filter and grille.

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

E.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 damage the oven's internal components.

F. 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.

G. Remove and clean the crumb trays. Be sure to replace the trays in the same positions from which they were removed, because they are NOT identical. Refer to Figure 3-2.

H. Clean the window in place.
