2.9 Chemical Connections

2.9.1 General (All Models)

!! ATTENTION DISHWASHER OWNER !!

Your dishwasher is designed to work best with liquid commercial dishwashing chemicals. Detergents must be a commercial non-foaming liquid. Champion strongly recommends that

you contact a qualified chemical supplier to supply these products and to setup your machine for the first time.

Your machine was shipped with the chemical dispensing adjustments set at their minimum settings, because of variations in chemical products. As a result of these variations, Champion is not able to advise you on the proper dispenser settings for any particular product nor can we recommend one supplier over another. You may wish to consult your equipment dealer or your Champion authorized service agent for help in contacting a chemical supplier in your area.

NOTE:

Residential automatic dishwashing detergents and rinse aids found in most grocery stores are designed to work in machines with cycles of 15 minutes or longer. Your Champion dishwasher cycle is complete in less than 3 minutes.

Champion does not recommend the use of residential automatic detergents and rinse aid products. These products may accumulate in your machine and produce poor washing results.

CAUTION:

Never use residential non-automatic dishwashing detergents such as JOY™ or DAWN™, or any other liquid designed for the handwashing of wares, in your machine.

Extreme foaming inside your Champion dishwasher will cause operation problems.

2.9.1 General (All Models) Cont.

NOTE:

The detergent and rinse aid chemical dispensing pumps are optional equipment on Models UH-200B and UH-200 dishwashers. The pumps may have been specified when the dishwasher was ordered and installed at the factory.

The following instructions assume that your dishwasher was delivered to your installation site with the dispensing pumps installed and explains the procedures for placing the chemical dispensing system in service for the first time.

If optional pump(s) are not installed, Refer to Section 2.10, Installing Optional Chemical Pumps, to install the chemical pump(s) before proceeding with Section 2.9.2.
