Dishwasher Views:
The standard methods for viewing your dishwasher are:
Plan View - Viewed from above
Front view - Viewed facing the top-mounted control cabinet switches. Side View - Viewed facing the load or unload sections.
1. The minimum distance from wall to dishwasher is 4" [103mm] to allow for utility connections.
2. The room ceiling height must be a minimum of 80" [2032mm] so the doors can be removed
completely.
3. The installation of your dishwasher must be performed by qualied service personnel.
4. Problems due to improper installation are not covered by the Warranty.
5. Compare the utilities at the installation site with the specications listed on each
Plumbing and Electrical Connection Diagram (P&E).
6. The dishwasher data plate is located on the left-hand or right-hand side of the top-mounted
control cabinet.
7. The conveyor direction of travel is referenced from the load section to
the unload section.
If the load section is on your right then direction of travel for the dishwasher is
Right to Left, (R-L).
8. If the load section is on the left then the dishwasher is called a Left to Right, (L-R), dishwasher.
Dishwasher Sections:
1. Load - Soiled ware is sorted and loaded on the conveyor belt.
Wares enter the dishwasher.
2. Prewash Tank - Soiled wares are sprayed to remove large particles and to loosen
heavy food-soils.
3. Wash Tank - Wares are washed with hot water and detergent.
4. Power Rinse Tank - Wares are rinsed with hot water to remove detergent and any
remaining food soils.
5. Auxiliary Rinse - Begins the hot water sanitization process.
6. Final Rinse - Completes the Hot water sanitization process.
7. Unload - Clean wares exit the dishwasher and ash dry on the conveyor belt.
8. Blower Dryer Option - Hot air is forced over wares to speed drying.

Track Alignment
The conveyor belt is supported by tracks inside each section of the dishwasher. These tracks must be
level when the sections are joined. If the tracks are not level then the level of the joined sections should
be re-checked and adjusted so that the tracks are level. The track mounting bolts may be loosened and
a small amount if adjustment can be made. Make sure the dishwasher sections are level before adjusting
the mounting of the tracks.
1. There are upper and lower
conveyor belt tracks.
2. Check the alignment of both sets
of tracks between each section
of the dishwasher.
3. Refer to the illustrations to the
right and verify the tracks are
level as shown.
4. Re-level the dishwasher sections
until the tracks are level.
5. Recheck the level of the conveyor
belt tracks.
6. Make any nal adjustments by
loosening the track mounting and
adjusting as necessary.
7. The tracks must be aligned and
level before installing the
conveyor belt.

When the dishwasher sections and the tracks are
level then the dishwasher section joints inside the
dishwasher must be capped by a u-clip that is
specifically designed to seal the joints and prevent
water leaks between the dishwasher sections.
1. Make sure the dishwasher hood and base
section joints have a section gasket
installed.
2. If the gasket is missing, then the sections
must be broken, a gasket installed, siliconed

Assembling the Conveyor Belt
The conveyor belt may be shipped separately
from the dishwasher on pallets or it may be rolled
up inside of the dishwasher. In either case, the
installation is the same.
1. Start at the unload end of the machine and pull
the conveyor belt around the end sprockets
until approximately 1.5 feet/76.2 cm of belt
rests on the upper track of the dishwasher.
2. Pull a section of belt to the next section along
the upper track into the unload end.
Roll the first section of conveyor belt
from the unload section toward the unload section.
3. Join the belt sections together by feeding a
conveyor rod through the links, spacers, and
rollers. Install a cotter pin on each end of the
rod to secure the assembly.
4. Use an assembled rod section on the belt as
a guide for the placement of the spacers, etc.,
continue this procedure until the conveyor belt
is assembled in a complete loop.
Connect the conveyor belt sections with
a rod, spacers, and washers included
in the hardware kit.
The assembled belt should
form a complete loop.

Sealing Section Joints
Machine section joints must be sealed using a food-grade
silicon sealant. Several tubes of approved sealant were
included in the installation hardware kit.
Study the photos on the right.
The top photo shows an incorrectly sealed joint. Note that the
joint seal has a valley indicating that insufficient sealant was
applied.
The bottom photo shows a correctly sealed joint. The joint seal
is filled and the transition between the sections is shallow.
To seal the section joints:
1. Make sure the machine sections are level, all utilities
and cross-connections are made and the sections are
bolted together.
2. Clean the joint with isopropyl alcohol to remove dust,
oil lm, and other contaminants.
3. Mask the joint edges with a quick-release masking
tape.
4. Apply a 1/8" bead of food-grade silicon sealant
using moderate pressure on the caulking gun to
ensure the sealant lls the joint.
5. Wait 1 minute for the sealant surface to rm slightly
(but before a skin forms), then wipe the joint with a
clean damp cloth.
Note:
If the sealant dries longer than 1 minute, do not try to wipe
the joint. Allow the sealant 30 minutes to dry, then cut the
sealant out of the joint and reseal the joint.

Introduction
The flight-type upright conveyor dishwasher consists of a series of wash tanks designed to clean a variety
of soiled ware moving through the tanks on a conveyor belt. Refer to the illustration below for a general
description of the machine.
Dishwasher Tanks and Options:
1. Load - Soiled ware is sorted and loaded on the conveyor belt.
Wares enter the dishwasher.
2. Prewash Tank - Soiled wares are ushed to remove large particles and to loosen heavy food-soils.
3. Wash Tank - Wares are washed with hot water and detergent.
4. Power Rinse Tank - Wares are rinsed with hot water to remove detergent and any
remaining food soils.
5. Quad Rinse - Auxiliary rinse begins the hot water sanitization process then the nal rinse completes the hot water sanitization process.
6. Unload - Clean wares exit the dishwasher and ash dry on the conveyor belt.
7. Blower Dryer Option - Hot air is forced over wares to speed drying.
8. Heat Recovery Option - Hot air exhaust is recycled to raise the incoming water temperature
for the nal rinse booster reducing energy costs.

Electric-Eyes and Idle Pump Start
The wash pumps start automatically when wares that
are placed on the conveyor belt pass through a set of
electric eyes that are mounted on the load-end of the
dishwasher. The electric eyes create an infrared beam
across the belt which, when blocked by wares, start the
wash pumps (see the photo to the right).
To start the wash pumps using the electric eyes:
1. Place wares on the belt.
2. Start the conveyor belt from the control panelor the Start/Stop station.
3. Continuing to place wares on the conveyor belt
will activate the electric eyes and keep the wash
pumps running until wares are no longer placed
on the conveyor belt.
Note:
The wash pumps operate on a timed cycle that will automatically stop the wash pumps when the wares
have moved through the machine, are sanitized in the final rinse, and then exit the machine.
It is important that the electric eyes be cleaned regularly to prevent soils from obstructing the infrared
beam. Clean the electric eyes with a mild detergent and a soft cloth. Do not use a scouring pad.

Conveyor Shut-off Shelf
WARNING:
Moving Conveyor Parts may cause INJURY OR DEATH.
Keep hands and clothing clear of the conveyor when the
conveyor is moving.
USE EXTREME CAUTION WHEN THE CONVEYOR
IS MOVING.
The Conveyor Shut-off Shelf is designed to stop the
conveyor belt when wares traveling on the conveyor belt
reach the end of the unload section. This prevents wares
from being damaged and prevents the conveyor belt from
jamming.The Shut-off Shelf is located on the extreme end
of the un-load end section of the dishwasher.
The Conveyor Shut-off Shelf functions in the following way:
1. When wares contact the shut-off shelf the shelf
pivots backward stopping the conveyor belt.
2. The shut-off shelf also will stop the optional
blower-dryer heat off if the machine is equipped
with the blower-dryer.
3. The wash pumps continue to run when the conveyor belt stops
4. The machine operator should remove the wareson the unload section of the belt making sure
that no wares have fallen below the conveyor
belt.
5. In the event that wares have fallen below the belt,
the operator must turn power off at the control
panel and then remove any wares. The machine
can be restarted when the wares are clear.
6. The conveyor belt will not run until the conveyor
shut-off shelf is moved back to the RUN position
as shown in the photos to the right.
