INSTALLATION

Plumbing Connections

!CAUTION:

Plumbing connections must comply with local sanitary and plumbing codes.

Water Connections

1.Connect the hot water supply (60oC/ 140oF Min) to the 1/2" I.D. fill hose. The fill solenoid valve is equipped with a flow control that will accept water pressures from 172 kPa/25 psi to 665 kPa/95 psi.

2.Install a manual shut-off valve in the water supply line to accommodate servicing the machine. The shut-off valve should be the same size or larger than the supply line.

3.The fill solenoid valve is equipped with a built-in strainer to protect from particles in the water supply.

Drain Connections

1.All Models are supplied with a flexible 5/8" I.D. drain hose, which must be connected to a 1-1/2" drain using a wye (Y) fitting.

Detergent

1.Use a qualified detergent/chemical supplier for your detergent, rinse aid, and chemical sanitizer needs.

2.Your machine is supplied with a detergent dispensing pump that is internally wired and ready for use. Using a liquid detergent, 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.

3.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 and factory time settings.

NOTE:

A nonclorinated detergent is recommended for your dishwasher.

Rinse Aid

1.An optional rinse aid pump may be supplied for all models. Using a liquid rinse aid, insert the labeled Rinse Aid pickup tube into the rinse aid container.

Chemical Sanitizer

1.Model 501LT is supplied with an internally wired chemical sanitizer dispensing pump. Using a 5.25% or 8.4% sodium hypochlorite solution, insert the labeled Chemical Sanitizer pickup tube into the chemical sanitizer container.

2.Contact your chemical supplier for adjustment of the chemical sanitizer.
