Menu 42: Detergent Dose
(default = 2 seconds)
0 to 19 seconds
This setting defines how long the detergent pump runs (in seconds) for each dose. Any value from 0 to 19 seconds may be
used.
Press the Scroll key to change the value of the blinking digit. Press the Next key to move to the next digit. Press the
Enter key at any time to accept the number displayed as the new setting for the Detergent Initial Charge.
NOTE: This menu is where the detergent dose time is set in seconds. But how often the detergent dose occurs depends on
the detergent dose interval set in Menu 43. The available dose intervals are every rack, every second rack, or every third rack.
Menu 43: Detergent Dose Interval
(default = 1 rack)
1, 2 or 3 racks
This setting determines when a detergent dose occurs in probeless mode, either every rack (1), every other rack (2) or every

number displayed as the new setting for the Detergent Dose Interval.
How a "rack" is counted depends on the setting in Menu 22 for Machine Type; Door Machine or Conveyor.
Door Dishwashers: A rack is counted each time a wash cycle completes, using the rinse signal activation as the trigger.
The Detergent Dose Interval will determine when detergent is dosed; every wash cycle, every other wash cycle, or every third
wash cycle.
For example, if the Detergent Dose Interval is set to 3 racks, the programmed Detergent Dose will occur every third wash
cycle.
Conveyor Dishwashers: A rack is counted each time the rinse signal activation time becomes equal to the "Rack Time in
Rinse" (set in Menu 25). The Detergent Dose Interval will determine when detergent is dosed.
For example, if the Rack Time in Rinse is set for 20 seconds and the Detergent Dose Interval is set to 3 racks, the
programmed Detergent Dose will occur after every 60 seconds of rinse signal.
Menu 44: Rinse Pump Speed
0.0 to 59.5 Revolutions Per Minute (RPM)
NOTE: This setting only effects the dispenser operation when the optional Rinse Pump is installed.
Rather than setting how long the rinse pump runs for each wash cycle, you control how much rinse agent is added by
adjusting the rinse pump speed. Press the Scroll key to change the value of the blinking digit. Press the Next key to move to
the next digit. Press the Enter key at any time to accept the number displayed as the new setting for the Rinse Pump Speed.
NOTE: Adjust the rinse pump speed to dose an appropriate amount of product needed for good results on wares. To
determine this adjustment, note the amount of rinse product per unit of water (check the dish machine specifications for rinse
water flow rate per minute) or observe the sheeting action of the product on wares. With the standard rinse pump tube, in
new condition, the EvoWash detergent pump will dispense approximately 0.5 ml per revolution.
Testing: When the Rinse Pump Speed value is being displayed, you can press and hold the Next key with the Enter key to
have the rinse pump run at the displayed speed setting.
