Middleby Marshall PS360 VII. Final Assembly, Installing the Conveyor and Belt Tandem oven models

B.Installing the Conveyor and Belt - Tandem oven models

NOTE

For non-tandem oven installations, skip ahead to Section VII, Final Assembly.

1.Insert the conveyor frame into the oven as follows:

Slide one hinged conveyor frame section into each end of the oven. The two sections butt against each other at the gap between the two oven sections. See Figure 2-17.

IMPORTANT

Be sure that the drive section of the conveyor frame is at the same end of the oven as the conveyor drive motor.

2.Slide the conveyor belt through the support rods underneath the frame, and thread it through the oven. Then, reach through the oven window and pull the free end of the belt through the oven so that it lies atop the conveyor frame.

After the belt has been pulled through the oven, check the following:

•The conveyor belt links must be oriented as shown in Figure 2-18.

•The smooth side of the conveyor belt must face UP.

3.Connect the inside master links. Check that the links are oriented as shown in Figure 2-18.

4.Connect the outside master links. Note that the outside master links have right and left sides. The right-side master link has an open hook facing you, as shown in Figure 2-19.

5.Check for freedom of movement of the conveyor belt by pulling it for about 2-3 feet (60 to 90 cm) with your fingers. The conveyor must move freely.

6.Check the tension of the conveyor belt as shown in Figure 2-15 (on the previous page). The belt should lift between 3- 4" (75-100mm). DO NOT OVERTIGHTEN THE CONVEYOR BELT. If necessary, the belt tension can be adjusted by turning the conveyor adjustment screws, located at the idler (right) end of the conveyor.

7.LOOSELY attach the conveyor drive motor to the end wall of the oven. Refer to Figure 2-12 (for ovens with standard conveyor frames) or Figure 2-20 (for ovens with heavy-duty conveyor frames).

8.Assemble the conveyor drive chain in place on the motor and conveyor drive sprockets.

9.Position the motor to adjust the deflection of the drive chain to 3/4” (19mm). DO NOT OVERTIGHTEN THE DRIVE CHAIN. Then, tighten the bolts to hold the motor in place.

VII. FINAL ASSEMBLY

1.Assemble the end plugs and motor housing onto the oven. These components are shown in Figure 1-1 (on Page 1).

2.Slide the conveyor extensions over the ends of the conveyor frame. Be sure that the extension with the drive sprocket opening is placed on the drive end.

NOTE

The PS360EWB oven does not use conveyor extensions.

3.Refer to Figure 2-21 for the correct location of each crumb tray. Then, install the crumb trays underneath the conveyor as shown in Figure 2-22. First, place the inside edge of the tray onto the bracket attached to the end plug. Then, swing the outside edge of the tray up and into place.

4.Press the end stop down over the edge of the conveyor extension at the exit end of the oven. See Figure 2-22.

5.After the oven is moved to its final location, adjust the bottom

section of the legs so that the oven is level and the casters
do not touch the floor.	13
