Manual Indexing for Each Regeneration
The control valve may be manually indexed to each
regeneration position as follows:
1. Remove the control valve cover.
2. Press down on the top of the drive gear to disengage the
cam gear. (See Step 1 in Start-Up Rinsing Procedure
section.)
3. With the cam gear disengaged, rotate the cam gear
counterclockwise to the various positions, using the same
steps as the Start-Up Rinsing Procedure.
The control valve may also be operated in a fast mode for
testing the control. To activate the fast mode, follow Steps 1
and 2 above to disengage the cam gear. When the cam
gear is disengaged, it should be advanced slightly in a
counterclockwise direction.
The switch will then activate the motor to cause the cam gear
to advance through all the cycles in about 30 minutes. The
control will not recognize a fast mode as a regeneration.
Manual regenerations can be initiated only by pressing the
manual regeneration switch on the face of the control.
