Self Cleaning Continuous Filter Chapter 3: Installation 27
Completing Mechanical Assembly
1. Connect duct work (as required) to the Self Cleaning Continuous Filter inlet and
outlet.
WARNING! Burning objects, such as lighted cigarettes, should not be put into the hood
or inlet ducting to the Self Cleaning Continuous Filter.
2. Connect discharge device to the hopper outlet.
Caution! The Self Cleaning Continuous Filter system is not intended for material
storage. Provision should be made for continuous hopper discharge while
maintaining the air seal.
3-5 Initial Start-up
WARNING! The crew chief or foreman should make a final inspection of the collector
internals and account for all personnel prior to activation of the
equipment.
Note: Failure to adhere to the following procedures could result in poor performance
of or damage to the Self Cleaning Continuous Filter unit or injury to
personnel.
Pre-Startup Checks
Auxiliary Equipment
1. Inspect all equipment before start-up to see that there are no foreign objects in
rotating equipment and that safety equipment is in place.
2. Start the fan, screw conveyor and/or airlock and inspect for proper rotation and that
all equipment runs smoothly. After making the necessary corrections, turn all this
equipment off.
Ductwork
See that all connections are tight and that all cleanout ports are closed. The ductwork must be
free of debris.
Starting the System
1. All doors and ports should be closed, with timer and auxiliary equipment off. Turn
on compressed air to collector and inspect the system for leaks. If air is leaking from
any blowpipe with the timer off, there may be a leak between its solenoid and
diaphragm valve. Inspect the ¼” O.D. tubing between the solenoids and diaphragm
valves to be certain that all connections are tight and there are no leaks. The tubing
must not be crimped. Shut off the compressed air supply.
2. Turn on the timer. The red “power on” indicator should light. Turn “OFF TIME”
and “ON TIME” knobs fully counterclockwise. The individual timing lights should
blink at 1.5 second intervals and the corresponding solenoid valves will be activated
(audible).
3. Turn on the air supply to the air header. All solenoid valves should be operating and
the exhaust air from each valve can be felt. Let the collector pulse for ten minutes to
clear all lines then set “OFF” time to between six to ten seconds with 85 psig air
supplied. Later this may be adjusted to suit your collection requirements based on
the dust loading.
