material into the dust collector, coating the newly installed filters faster than what normal operation would produce. AT MINIMUM, enough precoat material should be applied to the filters until the differential pressure, across the filters, increases by 0.5” w.g. This value can be exceeded to the user’s satisfaction. Once the appropriate differential pressure value is reached, the “Constant Feed” valve should be turned OFF. The feeder will now run in standard operation. Differential pressure, across the cartridge filters in the collector, can be monitored with a pulse controller, or a magnehelic gauge, if so equipped.
7.0 STARTUP/SHUTDOWN
7.1 Ensure that all mechanical/electrical connections have been made.
7.2 Ensure that precoat material is in the unit.
7.3 Ensure blower on the dust collector is operating!
7.4 Turn the PCF feeder switch to "HAND" (manual). If your unit is properly wired for automatic operation, then the switch can be turned to “AUTO”.
7.5 To power down the feeder, turn the switch to "OFF", and power down the blower on the dust collector.
8.0 MAINTENANCE
8.1 The Amtech PCF series feeders should provide years of trouble-free service. However, if you should experience an issue with your feeder, please contact your Amtech distributor.
8.2 Feeders will require periodical refills of precoat material. The frequency of these refills will be a function of your choice for cycle time.
