OPERATING CHARACTERISTICS
The unit can initiate a backwash cycle by PD or Periodic time or both, and manually. When a
backwash initiates, the FM-4P moves out of filtering mode, and individually washes each tank. The
systems pressure differential drops when cycle is complete, and the tanks are deemed clean. If the
pressure does not drop, troubleshooting of the filter system itself should be performed, starting with
solenoid and valve maintenance. Additional troubleshooting resources can be sought out on the tech
support page on the web at: www.alextronix.com

Ÿ
Solenoids defective or become defective when heated for long periods.
Ÿ
