Before ANY cleaning or servicing of the oven, perform the following procedure:

1. Switch off the oven and allow it to cool. Do NOT service the oven while it is warm.

2. Turn off the electric supply circuit breaker(s)

and disconnect the electric supply to the oven.

3. If it is necessary to move a gas oven for cleaning or servicing, disconnect the gas supply connection before moving the oven.

SECTION 4 - MAINTENANCE

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, 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.

When all cleaning and servicing is complete:

1. If the oven was moved for servicing, return the oven to its

original location. Adjust the legs so that they are seated

properly on the floor.

2. For gas ovens, reconnect the gas supply.

3. Reconnect the electrical supply.

4. For gas ovens, turn on the full-flow gas safety valve. Test

the gas line connections for leaks using approved leak

test substances or thick soap suds.

5. Turn on the electric supply circuit breaker(s).

6. Perform the normal startup procedure.

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,

because they are NOT identical. Refer to Figure 4-1.

G. Clean the window in place.
