Warranty of Machines: Champion warrants all new machines of its manufacture bearing the name "Champion" and

In the event that Champion elects to repair, the labor and work to be performed in connection with the warranty shall be done during regular working hours by a Champion authorized service technician. Defective parts become the property of Champion. Use of replacement parts not authorized by Champion will relieve Champion of all further liability in connection with its warranty.

tampering, improper installation, or failure to follow maintenance and operation procedures.

j. Wear on Pulper cutter blocks, pulse vanes, and auger brush.

Examples of the defects not covered by warranty include, but are not limited to: (1) Damage to the exterior or interior ﬁnish as a result of the above, (2) Use with utility service other than that designated on the rating plate, (3) Improper connection to utility service, (4) Inadequate or excessive water pressure, (5) Corrosion from chemicals dispensed in excess of recommended concentrations, (6) Failure of electrical components due to connection of chemical dispensing equipment installed by others, (7) Leaks or damage resulting from such leaks caused by the installer, including those at machine table connections or by connection of chemical dispensing equipment installed by others, (8) Failure to comply with local building codes, (9) Damage caused by labor dispute.

Warranty of Parts: Champion warrants all new machine parts produced or authorized by Champion to be free from defects in material and workmanship for a period of 90 days from date of invoice. If any defect in material and workmanship is found to exist within the warranty period Champion will replace the defective part without charge.

DISCLAIMER OF WARRANTIES AND LIMITATIONS OF LIABILITY. CHAMPION'S WARRANTY IS ONLY TO THE EXTENT REFLECTED ABOVE.

2. A 1/2" or larger main incoming supply line must be installed to the dishwasher.

3. A 1/2" or larger shut-off valve should be installed in the main water supply, as close to the dishwasher as possible for servicing.

FOR UH130: The UH130 has a built-in ﬂow control. The ﬂowing incoming hot water supply

pressure must be between 25-95 psi. The hot water supply must provide a minimum of 180°F/82°C, measured at the dishwasher.

FOR UH130B: The UH130B has a built-in ﬂow control. The ﬂowing incoming hot water supply pressure must be between 25-95 psi. The hot water supply must provide a minimum of 140°F/60°C, measured at the dishwasher for 40°F/22°C rise booster or 110°F/43°C for 70°F/39°C rise booster.

4. FOR UH230: The hot water supply must provide a minimum of 180°F/82°C, measured at the

dishwasher. A pressure regulating valve, PRV, (supplied), must be installed after the shut-off service valve if the incoming ﬂow pressure exceeds 20-22 psi.

FOR UH230B: The hot water supply must provide a minimum of 140°F/60°C, measured at the dishwasher for 40°F/22°C rise booster or 110°F/43°C for 70°F/39°C rise booster.

A pressure regulating valve, PRV, (supplied), must be installed after the shut-off service valve if the incoming ﬂow pressure exceeds 20-22 psi.

5. A water hardness of 3 grains/gal (US) [5.3 mg/L] or less is recommended. Excessively hard water will negatively impact wash results.

Drain Connections - UH130, UH130B, UH230, UH230B

! VERY IMPORTANT !

Do not connect the drain hose to a disposer. The dishwasher will not drain correctly.

Refer to the photo below.

1. All models are equipped with a 6 ft.. 5/8" I.D. drain hose. The maximum drain height connection must not exceed 3 ft.[1 m] and must be vented to prevent the wash tank from siphoning.

2. The drain hose is located at the rear of the dishwasher, and is secured to the rear of the machine by two clamps to maintain an anti-siphoning loop in the drain hose.

3. A 3/4" hose barb ﬁtting is strapped to the drain hose prior to shipment. The service part number for the hose barb is P/N 0512321.

4. Additional plumbing parts must be supplied by the plumbing installer.

5. The maximum drain ﬂow is 15 US gpm/12.4 imp gpm/60 lpm.
