The sump sweep system uses a three-way valve to
divert solution from the wash chamber to a spray bar on
bottom of the sump chamber. The spray bar generates
a high-pressure spray pattern that agitates the sump
solution and suspends solid particles. The solution then
flows through the filtration system which removes the
solid particles (See Cleaning out the Sump).

Detergents And Additives

Manufacturer's detergents are the only detergents
approved for use with our automatic parts washers.
They are specially formulated with rust inhibitors and
anti-foaming agents to optimize performance and
minimize maintenance. The use of any other detergent
during the warranty period will void the warranty.
To monitor the approximate concentration of detergent
in the wash solution, periodically examine the wash
solution in the sump chamber for the following indica-
tors:
• Rust inside the machine: not enough
detergent
• Excessive foaming: not enough detergent
• Thick, white residue on parts after washing:
too much detergent.
To maintain proper concentration under typical condi-
tions, add detergent each month after cleaning the
sump chamber. Follow recommended detergent quanti-
ties. Use a pH kit to determine the proper amount of
detergent to use. If you need help interpreting test
results, contact customer service.
Rust Inhibitor Additive
Factory detergents protect the entire inside of your
machine against the degenerative effects of water
evaporation. A rust inhibitor additive actually evapo-

protects metal surfaces, even while your machine is
sitting idle. For more information, contact your distrib-
utor or call customer service.

Preparing The Machine For Use

Before you begin to wash parts, it is important that you
properly prepare the machine. Before you begin to use
the machine each day:
• check the water level and add water to the
sump tank if necessary;
• check sump water cleanliness and run skimmer
as-needed to clean sump water surface;
• heat the water to operating temperature;
• add detergent if necessary (see Detergents);
• verify that none of the spray nozzles are
clogged; and
• clean the debris screen.
