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 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.
NOTE
ANY replacement parts that require access to the interior of the oven may ONLY be replaced by a Middleby Marshall Autho-
rized 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.
WARNING
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.  
When all cleaning and servicing is complete:
1.  If the oven was moved for servicing, return the oven to its original  location.
2.  If the restraint cable was disconnected to clean or service the oven, reconnect it at this time.
3.  Reconnect the electrical supply.
4.   Turn on the electric supply circuit breaker(s). 
5.   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 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 components.
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 2-16 (in Section 2, Installation) when replacing the 
crumb trays into the oven.
G.  Clean the window in place.
