Unpacking
❑Immediately after unpacking your machine, check for any possible shipping damage. If
any damage is found, save the packing materials, including the skids, and contact the
carrier immediately.
❑All the loose parts for your machine and the hardware needed for the assembly of the
sections are contained in a box located on one of the skids.
Locating
❑Before moving the sections into position, inspect the location site and be sure that the
electrical, plumbing, and ventilation services are provided in the correct locations.
Champion provides a Plumbing and Electrical Connections Drawing, (P&E), detailing
these requirements. Compare the site connections with the machine to ensure that they will
match when the machine is set in its permanent location.
❑With each section on its skid, place it as close to its permanent position as possible.
CAUTION:
Each section has piping underneath the base. Lift the section carefully to avoid
damaging the piping.
❑Carefully lift each section, and remove the skid. Remove any tape and shipping brackets.
❑Remove the wireway covers on the rear of each section and lay the wire bundles
to the outside.
❑Open all the doors. If you choose to remove the baffles for easier access to the section
ends, be sure to note their location for correct reassembly later. (See Pg. 18, Fig. 3)
❑Roll the conveyor belt toward the inside of the sections to make the
section assembling easier.
❑Move the center section (Wash/Rinse) to its final position and thread the feet in
as far as possible.
❑Move the other sections into position, leaving about 6 inches of separation between them.
Thread all feet in as far as possible. DO NOT BOLT THE SECTIONS TOGETHER AT
THIS TIME.
Assembling the Sections
❑Check the height of each section and determine which section is the highest
due to floor variations.
❑Begin with the Wash/Rinse section and adjust its height. Keep in mind that the other
sections will be leveled in relation to this section. Therefore, the height of the wash/rinse
section must compensate for floor height variations.
❑Level the wash/rinse section side to side and front to back in several places
using a bubble level.
❑Run a 1/2" bead of silicone sealant on the face of all sides of the hood gasket of the section
end you are going to join.

Page 14
INSTALLATION
Assembling the Sections (continued)
❑Move the next section closer to the prepared end of the center section and adjust the feet of
the second section so that the bolt holes around the hood and gasket align.
❑Slide the connecting hoses and clamps on the drain pipes and cross-flow pipes.
Do not tighten.
❑Level the second section side to side and front to back in several places
using a bubble level.
❑Check the alignment of the conveyor tracks inside the machine, drains,
cross-flows and wireways.
❑Bolt the HOOD sections together FIRST, using the 5/16-18 X 3/4" bolts, lockwashers and
nuts from the hardware kit.
❑Bolt the base together NEXT, using the 1/2-13 X 1" bolts, lockwashers, and nuts from the
hardware kit.
❑Recheck the level of the assembled sections and relevel the second section if necessary.
❑Adjust the hoses on the drain pipes and cross-flow pipes and tighten the clamps.
❑Feed the wire bundles through the wireways and connect the wires.
- Match corresponding numbers and connect them together.
- Connect all white and #2 wires together. White and #2 wires are neutral wires.
❑Connect the copper water lines at the rear of the sections. Be careful not to
cross-thread the connectors.
❑Connect the steam piping below the base (applicable to steam machines only).
❑Install the baffles if you removed them prior to connecting the sections.
❑Repeat the entire process for each section until the machine is completely assembled.
Assembling the Conveyor Belt
❑Start at the unload end of the machine and pull the conveyor belt around the sprockets until
approximately 1-1/2 feet of belt is exposed on the upper track of the machine.
❑Pull a section of belt from the next section along the upper track into the unload end.
❑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.
❑Continue this procedure until all the conveyor belt sections are joined.
❑Adjust the conveyor belt tension at the load end by turning the adjusting bolts on the
take-up assemblies. The take-up assemblies are located on either side of the load end
conveyor shaft. Loosen the adjusting bolt locknuts.
❑Turn each take-up adjusting bolt clockwise equally making sure that the conveyor shaft
remains square with the end of the machine.
❑Note the slack in the lower portion of the belt and be sure that the adjustment
removes the slack.
❑Check for the proper belt tension by lifting up the conveyor belt at the unload end. Proper
tension has been reached when the belt can be lifted off the track a maximum of 1-1/2 to 2
inches. Tighten the adjusting bolt locknuts.
❑RECHECK THE BELT TENSION IN 2-3 WEEKS AND READJUST AS NECESSARY.
(See Initial Start Up #17, Pg. 11)

Completing the Assembly
CAUTION:
Overtightening the belt can result in damage to the belt and the conveyor belt drive
assembly.
❑Trim any excess silicone sealant that may have squeezed out from between the assembled
sections. Apply a finish bead of silicone around the section joints.
❑Install the vent stacks on the load and unload sections of the machine.
Make sure the damper handles face toward the front of the machine.
❑Install the curtains. Long curtains hang in hooks on each end of the machine.
Short curtains hang in hooks on the inside of the machine. (See Fig. 6, Pg. 20)
❑Check each tank and the interior of the machine and remove any foreign material.
❑Install the screen supports, scrap screens, and access panels.
Installing the Optional Blower Dryer (Steam or Electric)
The blower dryer is available in either electric or steam and is shipped on a separate skid along
with the machine. The vent cowl and mounting hardware for the blower dryer are shipped in the
box containing the dishwashing machine parts and hardware.
❑Remove the blower dryer from the skid and install the unit on the top of the unload section
of the machine.
❑Bolt the blower dryer in place using the 5/16-18 X 3/4" bolts, flat washers, and lock
washers from the hardware kit.
❑Fasten the vent cowl on the discharge end of the blower dryer using the 1/4-20 plain nuts,
flat washers, and lock washers from the hardware kit.
❑Connect the electrical wiring by moving the prewired flexible conduit into position with
the 3" X 5" junction box located on the side of the blower dryer.

Deliming
Mineral deposits, which are frequently referred to as lime because of their white color,
accumulate in the interior of the machine over time. The amount of lime build-up depends on
the mineral content of your water supply. Machines in regions of the country that have hard
water (high mineral content) will require more frequent deliming than in regions
with soft water (low mineral content).
NOTE:
Consult your chemical supplier for an appropriate deliming solution.
WARNING:
Deliming solutions or other acids must not come in contact with
household bleach (sodium hypochlorite) or any chemicals containing
chlorine, iodine, bromine, or fluorine. Mixing will cause hazardous gases
to form. Skin contact with deliming solutions can cause severe irritation
and possible chemical burns. Consult your chemical supplier for specific
safety precautions.
• Weekly or as required
1.Inspect the interior of the machine for lime deposits.
2.Follow the chemical supplier’s recommendations for the deliming solution.
3.Thoroughly flush the interior of the machine when the deliming is complete.

Electric Eye Energy Sentinel System (Idle Pump Shut-off/Rinse Saver)
Circuit Explanation—
The electric eyes are infrared sensors and are located on the load end of the machine. The
sensors consist of an emitter and a receiver. These components switch the 120VAC control
voltage supplied to the pump timer.
When an object moving on the conveyor breaks the infrared beam between the eyes, contacts
(EER) close and complete the 120VAC circuit (Wires #7 and #27 in the control cabinet).
• The pump timer resets and the pump motors start.
• The pump timer and the final rinse timer begin to time down.
• The pump timer resets each time the beam is broken.
Component Location—
Refer to Fig.12:
The Emitter is mounted on the back of the load section.
The Receiver is mounted on the front of the load section.
Cleaning—
Be sure the emitter and receiver lenses are clean.
Wipe the lenses clean with a soft cloth and
common rubbing alcohol.
Alignment—
Electric eyes do not normally require aligning
except when replacing a defective unit.
The eyes are aligned visually. Make
sure they oppose one another across the
conveyor belt.

• A failure in the electric eye system most often results in the following conditions:
1. Pumps run constantly.
2. Pumps will not run at all.
• Inspect the components to isolate the defective component:
1. Make sure that the bypass switch is in the automatic position.
2. Inspect and clean the lenses of the receiver and the emitter.
3. Check that electric eyes are aligned.
• Check the indicator lights on the back of the electric eyes: (See Figure 15.)
1. Remove two screws holding electric eye covers. Rotate covers away from tunnel
end so you can see indicator lights inside the covers. Do not remove eyes from covers.
2. Make sure that the electric eyes are aligned opposite of each other across the belt.
3. Make sure that both Green LED’s are ON.
4. Block the beam completely. The Receiver Yellow LED should be OFF.
5. Unblock the beam completely. The Yellow LED should be ON.
6. If all LED’s check OK, but the system fails to operate, try replacing the receiver first,
and then the emitter.

Automatic Fill/Low Water Heat Protection
Dual Float Switches—
Refer to Fig. 16
Each tank contains a dual float. The device consists of an
angled stem containing two reed switches. Two stainless steel
ball floats slide over the stem and are free to move up and
down. The floats contain magnets. When the float moves on
the stem, it opens and closes its associated reed switch inside
the stem. The reed switches control relays. The relays control
the automatic fill and heat for different parts of the machine.
Float switches and their relays operate on 24VAC.
Circuit Explanation—
The following is a general explanation of the float switch
circuit. Refer to the electrical schematic on your machine for a
detailed description of the individual floats, relays, and wiring.
Bottom Float and Reed Switch:
-The bottom float controls the heat.
-When the bottom float is down, the bottom reed switch is Normally Open (NO).
-When the bottom float is up, the bottom reed switch is Normally Closed (NC).
Top Float and Reed Switch:
-The top float controls a fill valve.
-When the top float is down, the top reed switch is Normally Open (NO).
-When the top float is up, the top reed switch is Normally Closed (NC).
The Top and Bottom Floats work together:
Initial Fill—
-When the tank is completely empty, the top float is down and its reed switch is NO.
-The control relay for the float switch is de-energized.
-The fill valve for the tank is energized and the tank begins to fill with water.
- As the water level in the tank rises, the bottom float begins to move up.
-When the bottom float is completely up, its NO reed switch contacts close.
-This prepares the heat circuit, but the heat Does Not energize at this time.
-The tank continues to fill until the top float is completely up.
-The top float’s NO reed switch contacts close. Its control relay energizes.
-The fill valve de-energizes.
-The heat circuit energizes through the NC contacts of the bottom float and
the contacts of the control relay.
Dual Float Switch Assembly
Figure 16
28
During Normal Operation—
- If the water level in a tank falls below the level of the top float, the top float moves
down and its reed switch contacts open.
-When the water level falls below the level of the bottom float, the bottom float moves
down and its reed switch opens.
-The control relay de-energizes. The fill valve energizes and refills the tank.
-The heat circuit will de-energize until the water level in the tank raises the top float again.
-The bottom float keeps the heat circuit ready as long as the water level is above the
level of the bottom float.

Cross Flow Elbows
Proper water levels are maintained in the
tanks through a system of pipes and elbow
fittings. This system is called a water cross
flow system. Water flows by gravity from
the final rinse end of the machine back
towards the prewash tank.
Cross flow elbows are placed in the tanks as
required to adjust the flow of water from one
tank into the other. The proper adjustment of
the elbows is important for the correct
operation of the machine.
— IMPORTANT NOTE —
Cross flow elbow adjustment procedures can
be found in Appendix C at the end of this
manual. Refer to those instructions before
changing the position of any cross flow elbow.

APPENDIX A
EconoRinse Section (E2)
—This Option is for the UC-CW only. The EconoRinse section is installed between the
power rinse section and the unload section. It is designed to capture and recirculate the
final rinse water one additional time before it is used in the rest of the machine. The
section measures 2 feet in length and is equipped with a 1/4-HP pump motor. Machines
equipped with the EconoRinse section carry the model number UC-CW-WS. The WS
stands for Water Saver.
Curtain Location
—The E2 section contains one curtain located in the center of the section.
The curtain measures 32" X 10" and hangs from hooks located in the top of the hood.
EconoRinse Spray Pipes
—Two quick-release stainless steel spray pipes, (upper and lower) are located at the entrance
end of the E2 section. The spray pipes have removable caps for fast cleaning.
Tank Heat
—The E2 tank heat options are available in either electric or steam.
Electric tank heat uses a single 15KW heater element.
Steam tank heat uses a steam coil or injector.
THE PROPER TANK HEAT TEMPERATURE SETTING IS 170°F.
Operation
—The EconoRinse 1/4 HP Recirculating Pump runs ONLY when the final rinse operates.
1.Flip the main power switch on the front of the control cabinet to “ON.”
The Red light will illuminate.
2.Press the Green start button.
The conveyor belt will begin to move.
3.Place an object on the conveyor belt.
When an object on the belt enters the tunnel at the load end of the machine it breaks the
electric eye beam.
- The prewash, wash, and power rinse pumps run.
- The E2 pump DOES NOT run at this time.
4.The Final Rinse Timer controls the operation of the E2 1/4HP pump.
- As an object on the conveyor nears the EconoRinse section the Final Rinse Timer times out.
- The EconoRinse pump will run. The final rinse will operate as well.
5.The EconoRinse pump will stop at the same time as the final rinse. In addition,
- If the conveyor shut-off shelf is moved to the OFF position, the E2 pump will stop.
When the shut-off shelf is returned to the ON position, the E2 pump will run until the
final rinse stops.
6.If the Electric Eye Bypass Switch located inside the main control cabinet is placed in the
Manual position, the E2 pump will run constantly along with the other pumps whenever
the Green start button is operated.
