IV. ASSEMBLY

A.Base Pad, Legs, Casters, and Stacking

NOTE: Optional Stacking Lift Kit (P/N 30580)

The Stacking Lift Kit, P/N 30580, is available separately. This Kit provides a complete lift adapter set, specifically designed for stacking PS500 Series oven cavities. The Kit includes an instructional videotape.

1.Install the top panels in place on the top oven cavity. Follow the instructions provided with the top panels.

2a. Legs/Casters Installation (Standard) - Single Ovens, Double Ovens, and Triple Ovens with Leg Extensions

•Install one leg extension to each corner of the base pad using the supplied 1/2"-13x1-1/4" bolts, 1/2" flat washers, and 1/2" lockwashers. See Figure 2-4.

•Install one adjustable foot and one caster into the holes on the bottom of the leg extension. The adjustable foot should be installed into the OUTSIDE hole (closest to the front or rear face of the oven). The caster should be installed into the INSIDE hole.

2b. Legs/Casters Installation - Triple Ovens Without Leg Extensions

Install one adjustable foot and one caster into the 3/4" holes on the bottom of the base pad. The adjustable foot should be installed into the OUTSIDE hole (closest to the front or rear face of the oven). The caster should be installed into the INSIDE hole. See Figure 2-5.

2c. Legs/Casters Installation - Quad Ovens

•Install one outrigger to each corner of the base pad using the supplied 1/2"-13x1-1/4" bolts, 1/2" flat washers, and 1/2" lockwashers. See Figure 2-6.

•Install the spacer plates and casters onto the outriggers using the 3/8"-16x1" screws, 3/8" flat washers, and 3/8"-16 hex nuts supplied in the Installation Kit. The two locking casters should be installed on the front side of the oven.

•Install the adjustable feet into the holes on the underside of the outrigger assembly.

3.Install the base pad onto the lower oven cavity. Check that the eyebolt welded onto the pad faces the rear of the oven.

4.Stack the oven cavities. If necessary, refer to the instructional videotape provided with the Stacking Lift Kit (P/N 30580).

B.Restraint Cable Installation

Because the oven is equipped with casters, a restraint cable assembly must be installed to limit the movement of the appliance without depending on the connector and the quick disconnect device or its associated piping. One end of the cable is anchored to the eyebolt on the rear surface of the oven's base pad, while the other is anchored to the wall. See Figure 2-7.

After connecting the restraint cable, move the oven to its final location. Adjust the bottom (hex) sections of the feet so that the casters are off the floor. For quad ovens, lock the two front casters.

C.Conveyor Installation

NOTE

Split belt conveyors can only be installed from the end of the oven with the drive motor.

Single-belt conveyor assemblies may be inserted into either end of the oven. If it is to be installed from the end of the oven without the drive motor, the drive sprocket assembly must be removed.
