I. MAINTENANCE - DAILY
A. Check that the oven is cool and the power is disconnected,
as described in the warning on Page 20.
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. Refer to Figures 4-1, 4-2, and 4-3 for the
locations of the grills and vents.
D. Check that ALL cooling fans are operating properly.
Figure 4-1 - Cooling Fan/Vent Locations:
All ovens except PS360EWB and PS360WB70
CAUTION
If a cooling fan is not operating correctly, it must be replaced
IMMEDIATELY. Operating the oven without adequate cool-
ing 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. Be sure to replace the
trays in the same positions from which they were re-
moved, because they are NOT identical. Refer to the
drawings on Page 10 in the Installation section.
G. OVENS EQUIPPED WITH WINDOWS ONLY: Clean the
window in place.
