kPa/25 psi to 665 kPa/95 psi.
2. Install a manual shut-off valve with 3/4" garden hose connection in the water supply line
close to the machine to accommodate installation and servicing the machine. The shut-off
valve should be the same size or larger than the supply line.

water supply.
Drain Connections
1. All Models are supplied with a flexible 5/8" I.D. drain hose, which must be connected to a

Detergent/Chemicals
Use a qualified detergent/chemical supplier for your detergent, rinse aid, and chemical
sanitizer needs.
1. Your machine may be fitted with an optional liquid detergent dispensing pump. Insert the
labeled detergent pickup tube into the detergent container. The pickup tube has a strainer on
the end to prevent crystallized chemical from clogging the supply lines.
2. The cycle timer located in the main control cabinet is equipped with adjustable cams for the
chemical dispensing pump(s). The cams control the length of time that the pumps operate.
A qualified person may adjust the cam settings if necessary. Refer to the timer chart
diagram(s) at the end of the manual for timer cam locations. Factory time settings are only
approximate. Have your chemical supplier check the concentration and make the necessary
adjustments.
NOTE:
A nonchlorinated detergent is recommended for your dishwasher.
