HOW TO REDUCE THE CLEARANCE HEIGHT OF THE CONTROL BOX DURING MOVE-IN

This procedure will reduce the overall height of the control box by 4-1/2” to allow it to travel through a low-height corridor or doorway.

The control box must be securely supported by at least two people while its mounting studs are being shifted to lower slots of the shipping braces.

The rear of the main control box is attached to the two shipping braces on the dual rinse/final rinse section by four 5/16-18 threaded studs, washers, lock washers, and nuts. The shipping braces have slots that allow the control box to be lowered by 4-1/2”. (Fig. 1).

– 4 –

1.Remove the two shipping hinges from the side of the control box by removing the two 5/16-18 bolts from each bracket.

2.While two people are securely supporting the main control box, remove the four 5/16-18 nuts, lock washers, and washers from the inside of the shipping braces behind the control box.

3.Using at least two people, CAREFULLY withdraw the main control box’s rear studs from the shipping braces. Lower the control box threaded studs to the lower slots on the braces. Refasten the control box with the same 5/16-18 nuts, lock washers, and washers removed in step 2.

4.Move the dishwasher past all low-height corridors or doorways.

5.Reverse steps 3, 2, and 1 to return the main control box to its original shipping condition for proper installation.

UNPACKING

Immediately after unpacking the dishwasher, check for possible shipping damage. If the machine is found to be damaged, save the packaging material and contact the carrier within 15 days of delivery.

Before installation, test the electrical service to make sure it agrees with the specifications on the machine data plate located on the control box. The electrical diagram is located inside the control box.

Strainer baskets, strainer pans, pump inlet strainers and wash arms are taped and shipped in place. Remove tape, but retain parts in their proper places. If any parts are temporarily removed during installation, return to their proper places after installation is complete.

Before installing, check to make sure that necessary electrical, plumbing and exhaust accommodations are provided at the installation location. Take measurements of site’s plumbing, electrical and exhaust connections; then take corresponding measurements of the machine to make sure all connections are correctly mated. If necessary to lower control box during move-in, slotted holes are provided on the control box shipping braces to allow adjustment for clearance height. Refer to page 4.

Removing Each Section From Its Skid

Do not use a forklift directly on the machine frame or tank to move or lift machine sections. Doing so may result in damage to the machine.

1.Using a forklift or pallet jack, raise one end of the skid and unthread the feet from the legs as far as possible without removing the foot from the leg. Repeat for other end until all feet have been extended out. Lower the skid back to the floor. This will now allow the machine to sit on its feet so the skid can easily be removed.

2.Remove the two end plate screws from the 2x4 runners, located just inside the front and rear legs, at each end of the skid.

3.Remove all lag bolts from the top of the skid cross members along either the front or rear of the machine.

4.From the opposite side of the machine that the lag bolts were removed in step 3, pull the entire skid assembly out from beneath the machine section.

5.Thread the feet into the legs as far as possible; then back out three full turns. Standard legs have 3” threaded studs for maximum adjustment. If special feet were ordered with extra-long leg shanks to accommodate a highly sloped floor, installthemwherethelowpointsintheflooroccuratleglocationsonthemachine before setting the unit on the floor.

6.Open all inspection doors and remove all wrapped parts and boxes from inside each machine section.

–6 –

7.Remove any packaging, tape, wire and bracing from each section. Remove all rear and lower panels.

8.Verify that shipping tape has been removed from all floats in each tank and that the floats are free to operate properly.

NOTE: Do no throw out any loose parts. These may be required for installation or operation.

LOCATION

Allow adequate space for machine installation and operation. Place the machine sections close to their final position. Allow space to work on the ends of the center section.

Review, but do not remove tags or labels. Remove tags after installation is complete

Positioning the Center Section

Use a chalk line on the floor to align the machine along its complete length.

With each section in its approximate final position, determine which section is at the high point in the floor. Machine assembly begins after the center section has been leveled to a height that compensates for the floor height of the other sections.

Leveling the Center Section

Leveling is an important installation function because it could affect door operation and cause leaks once the machine is operating.

•Level the center section along its length by opening the doors and placing a level between the doors along the tank support rail (Fig. 2). Do not check level on top of doors. Adjust the feet in or out as required to level.

Fig. 2

– 7 –

•Continue to level the center section front to back by removing the top panels and placing level across the top of the chambers on both ends of center section (Fig. 3).

ASSEMBLY

Rotating Control Box 90 Degrees

The main control box is shipped with the upper and lower shipping hinges connected to the side of the control box. Remove the four 5/16-18 nuts, lock washers, and washers from the inside of the shipping braces behind the control box. Use the shipping hinges (Fig. 1) to rotate the control box 90 degrees. Do not remove the shipping hinges until after the control box is secured to the unload section.

Pull the control box out to allow mating of center and unload sections without interference with studs projecting from rear of control box.

Installing Foam Tape on Chamber Flanges & Control Box Mounting Surface

Cut strips of vinyl foam tape to fit the top, bottom, and vertical sides of the chamber flanges on the end of the load and unload sections to make a good seal. Apply two strips of foam tape to the vertical edges of the chamber ends, two horizontally across the top of the chamber ends, and one strip horizontally across the bottom flanges (Fig. 4). Place the foam tape approximately 1/16”-1/8” from the outside edge of the chamber. After the foam tape is applied, trim the excess tape along the chamber edges (Fig. 5).

NOTE: The vertical piece of foam tape on the outer edge at the front of the machine must be folded over ½” on the sticky side with the rolled edge of the tape positioned towards the front of the machine (Fig. 6).

2.With the control box rotated 90 degrees, move the unload section to within several inches of the center section behind the control box.

3.Maneuver the unload section so that the four 5/16-18 threaded studs on the back of the control box protrude thru the mounting holes on the unload section.

4.Secure the control box to the unload section using four 5/16-18 nuts, lock washers, and washers.

5.Once the control box is secured to the unload section remove the two shipping hinges from the side of the control box by removing the two 5/16 bolts and associated hardware from each hinge. The control box is now part of the unload section.

6.Install two 5/16 round head screws in open holes of control box where shipping hinges were removed.

7.Remove the hinges from the shipping braces by removing the cotter pins and hinge pins.

8.Remove the two shipping braces from the end of the dual rinse section by removing the three 5/16 bolts and associated hardware from each brace.

9.Reinstall the detachable leg section removed in step 1.

Positioning the Adjacent Load or Unload Sections

Move the adjoining (load or unload) section to within several inches of the prepared end of the center section. Adjust the feet of the section adjacent to the leveled center section so tank supports are the same height. Peel the protective paper from the vinyl foam tape and move the second section to its final position. Be very careful that mating components connect and fit together properly.

Leveling the Load and Unload Sections

The tank support rails should be level across the entire length of the machine (Fig. 2). Sections to be mated should be level front to back (Fig. 3).

•All adjoining components of the two sections are exactly in line with each other.

•Top corners of adjoining sections are the same height.

Joining the Sections Together

Use drift pins to align the holes in the horizontal and vertical chamber flanges of the mated sections. Use C-clamps to hold the sections in position while bolting the chamber front and back flanges together. Exercise care to avoid tearing the foam tape seal.

Do not use a forklift directly on the machine frame or tank to move or lift machine sections. Doing so may result in damage to the machine.

Secure the vertical frame corner posts together at two locations using the appropriate hardware (Fig. 8).
