CAM 6: Cam 6 is an adjustable can and controls the detergent pump.
FUNCTION: The detergent pump cam works off the normally closed contacts of cam 6. This requires the switch arm to be held
open by the cam and allowed to drop into the notch to operate the pump. The time that the detergent pump will remain energized
must be determined in the field to suit the chemical used and water conditions.
SETTINGS: The left side of cam 6 must be set to drop in past the starting point of the wash pump cam. The adjustment for deter-
gent volume must be made with the right side of the cam. To increase the volume, the notch should be increased or to decrease
the amount of detergent the notch should be closed slightly in increments until the correct level is reached.
CAM 7: Cam 7 is an adjustable cam and controls the rinse aid pump.
FUNCTION: The rinse aid pump cam works off the normally closed contacts of cam 7. This requires the switch arm to be held
open by the cam and allowed to drop into the notch to operate the pump. The time that the rinse aid pump will remain energized

SETTINGS: The left side of cam 7 must be set to drop in past the starting point of the fill cam and after the drain solenoid has
closed. The adjustment for rinse aid volume must be made with the right side of the cam. To increase the volume the notch should
be increased or to decrease the amount of detergent the notch should be closed slightly in increments until the correct level is
reached.
