WARNING
Before performing any service that involves electrical
connection or disconnection and/or exposure to
electrical components, always perform the Electrical
LOCKOUT/TAGOUT Procedure. Disconnect all circuits.
Failure to comply with this procedure can cause
property damage, injury or death.
The pump motor(s) must rotate in a clockwise direction

Pump Motor Rotation
This rotation was checked at the factory but must be
rechecked before putting the dishwasher into service.
Note: There may be more than one pump motor
depending on the model.
Fill/Rinse
Final Rinse water is used to fill the dishwasher’s wash
tank(s). The water supply must have a water temperature
of 180°-195° F with a dynamic flow pressure of 15 to 25
PSI at the dishwasher.
Note: If the dishwasher has been supplied with either a
machine mounted booster or a remote booster, the
water supply temperature must be 140° F minimum.
If the incoming water supply pressure is below the required
15 PSI, an optional pressure booster pump will be required.
If the incoming water supply pressure is greater than 25
PSI, a pressure reducing valve (optional) will be needed.
The unit requires 72 gal/hr of 140°F water.
Connect a ¾" pipe to the line strainer.
For a piping run greater than 20 ft, increase the pipe size
to insure proper flow pressure at the dishwasher.
