SECTION 2 - INSTALLATION

1.Lift the conveyor and position it in the oven as shown in Figure 2-9.

2.Continue moving the conveyor into the oven until the frame protrudes equally from each end of the oven (about 18"/ 457mm).

3.Check that the retainers located on the underside of the conveyor frame rest firmly against the lower end plugs, as shown in Figure 2-9.

4.When the conveyor is positioned properly, check for free- dom 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.

5.If the drive sprocket was removed when installing the conveyor, replace it at this time.

6.Install the drive chain between the conveyor drive sprocket and the motor sprocket. To install the chain, it will be necessary to lift the drive end of the conveyor slightly.

7.Install the conveyor drive motor cover.

8.Check the tension of the conveyor belt as shown in Figure 2-10. The belt should lift between 3-4" (75-100mm). 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 (right) end of the conveyor. See Figure 2-10.

9.If necessary, links can be added to or removed from the conveyor belt to achieve the correct deflection of 3-4" (75- 100mm). If links must be removed from the belt, it can be reattached to the conveyor as follows:

a.The conveyor belt links must be oriented as shown in Figure 2-11.

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

c.Connect the inside master links. Check that the links are oriented as shown in Figure 2-11.

d.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 2-11.

e.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.

f.Return to Step 8, above, to re-check the belt tension.
