Middleby Marshall Model PS536 Conveyor Installation, Assembling and tensioning the conveyor

D.Conveyor Installation

1.Unfold the conveyor frame so that it lies flat on the floor. As you unfold the frame, check that the locator pins shown in Figure 2-8 lock into the slots on the bracket.

2.Refer to Figure 2-8. Note the locations of the four tensioning screws (2 per side) in the slotted holes on the brackets. Loosen these screws to allow the conveyor to be properly tensioned.

3.Lift the conveyor belt away from the frame, as shown in Figure 2-8, to check the belt tension. The belt should lift between 1-2" (25-50mm).

If it is necessary to adjust the belt tension, gently push the two conveyor frame sections closer together, or further apart, as required. Then, re-check the tension of the conveyor belt. Repeat this step as necessary until the proper belt tension is achieved.

4.When the belt tension is correctly adjusted, tighten the two tensioning screws on each side of the conveyor frame. This fastens the two frame sections together at the correct belt tension.

5.If it is necessary to add or remove conveyor links to achieve the correct tension, OR if it is necessary to reverse the conveyor belt for correct orientation, the belt will need to be removed from the conveyor frame. If this is necessary, perform the following procedure:

a.Remove the master links using long-nose pliers. Then, roll up the belt along the length of the conveyor frame.

b.Add or remove belt links as necessary to achieve the correct belt tension.

c.Replace the belt on the conveyor frame. Check the following:

•The conveyor belt links must be oriented as shown in Figure 2-9.

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

d.Connect the inside master links. Check that the links are oriented as shown in Figure 2-9.

e.Connect the outside master links. Note that the outside master links each have an open hook on one side. This hook aligns with the hooks along the sides of the other conveyor links. See Figure 2-9.
