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.

NOTE: FOR MODEL UL-100 ONLY

The UL-100 model is a low temperature dishwasher utilizing a chemical sanitizing final rinse. Use a sodium hypochlorite (Chlorine) based sanitizer at a minimum concentration of 50 PPM in the final rinse. Use chlorine test papers to verify and monitor the 50 PPM chlorine level. (Consult local authority in Canada for proper concentration).

Some metals, including silver, aluminum, and pewter, are attacked by sodium hypochlorite (chlorine sanitizer). Avoid washing these metals in a UL-100 model dishwasher.
