D. Conveyor Installation
1. Unfold the conveyor as shown in Figure 2-12. Then,
begin to slide the conveyor into the end of the oven. The
conveyor can only be installed from the end of the oven
with the drive motor.
2. Continue moving the conveyor into the oven until the frame
protrudes equally from each end of the oven. Check that
the crumb tray supports located on the underside of the
conveyor frame rest firmly against the lower end plugs,
as shown in Figure 2-13.
3. When the conveyor is positioned properly, check for
freedom of movement of the conveyor belt by pulling it
for about 2-3 feet (0.6-1.0m) with your fingers. The drive
and idler shafts must rotate smoothly, and the belt must
move freely without rubbing on the inside of the oven.
4. Check the tension of the conveyor belt as shown in
Figure 2-14. The belt should lift about 1″ (25mm).
DO NOT OVERTIGHTEN THE CONVEYOR BELT.
NOTE: If necessary, the belt tension can be adjusted by
turning the conveyor adjustment screws, located
at the idler (non-control) end of the conveyor. See
Figure 2-14.
