Filter Operation & Start-Up Procedure Continued
Start-Up Procedure
1. Check plant air pressure in the filter air tank.
2. Check screw conveyors and airlocks (if furnished) for proper directions of rotation.
3. Controls should be wired in accordance with schematic diagram. Square and round model filters
are normally pre-wired, fully assembled and tested at the factory. Check all wiring connections to
assure proper bag cleaning sequence. The air tank pressure gauge should have a working range of
0-160 psig.
4. Set the controller “off” time adjustment to the minimum time by rotating the dial counterclockwise.
Allow the sequence controller to operate for 5 to 10 minutes to assure the mechanism has not been
damaged in shipment and to allow a short run-in time for the electronics.
5. Set the controller “off” time adjustment to a longer time span by rotating the dial
clockwise until you cannot turn the dial any further. With the “off” time adjustment at this setting,
check to insure that the relief valve relieves at no more than 125 psig. This provides pressure relief
safety for the air tank.
6. Set the controller “off” time adjustment to the desired time by turning the dial to the desired
setting.
7. If a venturi-jet blast valve does not fire on start-up, first check the output LED to confirm that
power is being sent to the solenoid on the venturi-jet blast valve.
Shut-Down Procedure
After the filter is placed into operation, a good practice to follow on shutdown is as follows:
1. Shut off the suction fan only.
2. Allow the reverse air cleaning, airlock and screw conveyor to operate for at least 15
minutes (a longer period of time is desirable if the operation will allow).
3. Then shut down the remainder of the system.
