AUTOCLEAN UNIT OPERATION
When wired as shown above, the AUTOCLEAN control will sense operation of the air cleaner fan motor.
When the motor is turned ON, the AUTOCLEAN patiently waits for when the motor is turned OFF. When
OFF occurs, the AUTOCLEAN will wait for a time to clean. This time is adjustable from 0 to approximately
10 minutes. Single cartridge units are not adjustable.
The AUTOCLEAN will then cause the Vibra-Pulse

cleaning system to clean each of the filter stations,
pausing for approximately 30 seconds to 10 minutes between filters to allow the air supply to refresh. The
amount of time each filter is cleaned is determined by the CLEAN TIME control which is adjustable from 0 to
60 seconds. Refer to the primary Owners Manual for recommendations on CLEAN TIME duration, or start
with an initial setting of 15 seconds. Once the complete sequence has been followed, the control waits for
motor startup to occur again. Restarting the motor during a cleaning cycle stops cleaning operation and resets
the controller for the motor off.
NOTE: The AUTOCLEAN will clean through when power is first applied unless the fan is started.
To increase the OFF TIME, adjust the timer potentiometer clockwise. Refer to Figure 9. Full counter
clockwise is 5 seconds, the halfway position is approximately 5 minutes and full clockwise is 10 minutes. The
ON TIME duration potentiometer setting process is the same as described for the OFF TIME, except the
range is 2 seconds to 60 seconds.

** On Dust Drawer models, the collected dust MUST be removed from the unit after each
completed cleaning cycle to ensure that it is not re-captured on the filter. When collecting explosion
hazardous materials, removal of collected dust may be a Code requirement.
