SETTING UP YOUR UNIT
CAMCORP dust collectors are shipped in various states of assembly depending on the
size and configuration of the unit. Before attempting to move the dust collector or any of
its sections, review both the certified general assembly drawing supplied with your unit
and the rigging and lifting guidelines included in this manual. Become familiar with the
size and number of sections to be assembled, the orientation of inlet(s), outlet(s), access
door(s), and fan as well as the number and location of lifting lugs.
Dust collectors of this type are manufactured from steel sheets and are quite flexible.
Therefore, even though care has been taken to maintain dimensional accuracy and
squareness, some difficulty should be anticipated, and temporary bracing in the field may
be required.
Rigging and Lifting Guidelines
1. Do not lift the dust collector by any attachments other than the lifting lugs
provided.
2. Use all of the lifting lugs provided on the dust collector, or a section of the
dust collector, when making a lift.
3. If the lifting lugs are located below the roof line of the dust collector or
below the top of the section of the dust collector, a vertical pull must be made
to avoid crushing the top of the unit. Use spreader beams to accomplish this
vertical pull.
4. Attach tag lines at several locations to be able to control the unit when lifted
and to prevent spinning or swinging.
5. The dust collector should be lifted and lowered at a slow, uniform rate and
not allowed to bounce or joggle since this can cause excessive impact
stresses at the lift points.
Doors and Flanges: Hold-downs on doors should only be hand tightened. Excessive
pressure can distort the door panel itself resulting in leakage. All bolts on flanges should
be tight. All holes in the dust collector must be plugged prior to start-up if not being
connected.

Platform Installation: The platform, ladder, handrail, and bracing are to be installed as
shown on the special platform detail provided. Use the part ID’s to locate the parts in the
proper location.
Explosion Vents (where applicable):
1. Figure 6 – The explosion vents are attached with a minimum of standard
steel fasteners for shipment. THESE MUST BE REMOVED and the
PVC Bolts installed that are included in the shipment. Extreme care should
be exercised when installing the PVC Bolts as they are very fragile. A
gasket is factory installed that will provide a seal between the vent panel
and the frame. DO NOT use silicone sealer or any other sealer or adhesive
at this joint as this will prevent the vent from operating properly.
2. The area around the vents should be clear of any personnel or obstructions
to prevent injury or damage.

Electrical: A 120-volt, 60-Hertz, 1-Amp circuit is required to operate the dust
collector’s Solid State Timer. A 230/460V 3-phase circuit is required to run the Pulse
Arm drive motor and the Cleaning Air PD (Positive Displacement) pump motor. Note:
The Adjustable Timer needs to be mounting were the Pressure Gauge on the PD Pump is
visible.

Gauges: Check the pressure differential gauge to make sure that the high-pressure tap is
connected below the tube sheet and the low-pressure tap is connected above the tube
sheet. Verify that the gauge have been zeroed prior to connection when it is in its
permanent mounting position.
Cleaning Air PD Pump: The PD Pump must be install at the base of the filter to
accommodate installation of the Air Supply line. Securely anchor in permanent location.
Required line size as follows:
Air Supply
Model: Pipe Diameter
HVP48 thru 112 1”
HVP 152 thru 256 1-1/2”
HVP 312 thru 504 2”
Auxiliary Equipment: All auxiliary equipment must be installed according to its
manufacturer’s specifications and interlocked with the entire system as needed. Direction
of rotation of each item must be checked prior to start-up of the entire system.

TOP LOAD BAG AND CAGE INSTALLATION
1. Inspect the cage for any signs of damage, warping, bent wires, or missing
welds.
2. Inspect the filter bag for any signs of mold, mildew, ripped seams, or holes.
3. Lower the closed end of the bag through the hole in the tube sheet.
4. With your hands, “kidney shape” the snap band bag top in order to fit and
align it within the tube sheet hole.
5. Fit the groove of the snap band to the I.D. of the tube sheet hole and allow it
to expand and audibly snap into place. If the band will not snap into place
initially, do not push on the “dimple” as doing this will permanently damage
the snap band. Instead, kidney shape the snap band from the opposite side of
the band. Then you can allow the band to expand and audibly snap into
place.
6. Check the fit of the snap band to the tube sheet. It should be even in height
above the tube sheet around the entire circumference, which will confirm to
the installer that the tube sheet is centered and well secured into the middle
groove of the snap band.
7. Lower the cage into the bag and press that cage top down into the bag’s snap
band I.D. When in position, the rolled flange of the cage top will rest on the
tube sheet and the bag and cage assembly will be rigidly mated. The O.D. of
the cage top provides a compression fit to the I.D. of the snap band.
8. Disconnect the drive chain to allow the pulse arm to rotate freely to access
the holes under the arm if necessary.
9. Replace access doors and tighten accordingly. You are ready to begin start-
up procedures if all other preceding tasks and hook-ups are completed.

START-UP CHECKLIST
1. Installation
Make sure the unit is secured to grade. The ladder(s) and platform(s) must be
tightened and set up according to OSHA requirements. Ducting and piping must
be secured and routed out of the way of traffic whenever possible to avoid injury.
Ducting must also be free of all debris including moisture.
2. Interior of the dirty air plenum
A. Make sure that the filter bag assemblies hang straight and the bottoms do not
touch each other or any part of the collector interior. If this occurs, the bags
will have holes worn in them wherever they contact and will require
replacement.
B. High-level alarms should be connected sufficiently below the air inlet(s) to
avoid a plugged up inlet or blinded off filter bags.
3. Clean air plenum
A. Properly install weights onto Weight Relief valve the end of the tank
assembly.
B. All bolts on the flanges must be in place and properly tighten.
C. Verify that the pulse arm drive is properly installed.
D. Note: Gear Reducers are shipped without oil. Reference attached Manual for
proper level.
4. Positive Displacement Pump
A. All supply air lines must be clean internally before connecting to blower.
B. Verify Inlet filter is properly installed.
C. Verify V-belt alignment and tension.
D. Note: PD pump is shipped without oil. Reference attached Manual for
proper level.
E. Verify proper rotation.

5. Exterior of dust collector
A. Access doors, inspection ports, and relief vents should seat effectively to
prevent leakage.
B. All bolts must be properly tightened.
C. Operate any equipment connected to the dust discharge of the dust collector.
Check the rotation of any motor driven equipment such as rotary airlocks,
horizontal unloading valves, live bottom bin activators, and screw conveyors.
Check slide gates and butterfly valves for binding.
6. Explosion relief panels – shear bolt style (where applicable)
A. Inspect for broken or missing bolts.

START-UP DUST CONTROL SYSTEMS
1. Fan or blower system
A. Start the fan or blower and check rotation.
B. Check dust pickup points for proper suction; balance airflow in individual
ducts.
C. Check for air leakage at all flanged connections.
2. Equipment start-up sequence
A. Start the pulse arm drive motor (direction of rotation is not critical).
B. Start the PD pump motor and check rotation.
C. Adjust timer Off-time by watching pressure gauge on PD pump. The
pressure in the tank should peak between 7-8 PSI. Increase or Decrease time
to obtain the correct pressure. Note: Verify the Weighted relief valve in the
clean air plenum is not activating – decrease Off-time if it is bleeding air.
D. Dust take away equipment such as rotary airlocks, screw conveyors,
horizontal unloading valves, live bottom bin activators, and pneumatic
conveying systems can now be started in their correct sequence.
E. Check that all access doors, hatches, ports, and other openings are closed and
latched or bolted.
F. The main exhaust fan can now be started and brought up to speed.
G. Start the dust laden air through the collector. The collector should be started
under partial load to allow the bags to become slowly and evenly coated with
dust particles.
On pneumatic conveying systems, watch the differential pressure gauge
closely for the first hour or so. If unstable, the collector discharge system
may be too small for the volume it is seeing. A quick fix is to reduce the
material feed until the discharge rate can be increased.
8-1

CLEAN AIR MANAGEMENT COMPANY, INC.
8224 Nieman Road iLenexa, Kansas 66214 Phone: [phone] Fax: [phone]
H. Observe the manometer or magnahelic differential pressure gauge reading.
As the new filter bags become coated with dust, the efficiency of the filtering
action increases, and the differential pressure across the filter bags will also
increase. Slowly bring the collector to full load and note the final pressure
drop across the filter bags. Never allow the pressure drop across the filter
bags to exceed 17” w.g. maximum or filter bags may collapse.
I. Check the main airflow with a Pitot tube, or equivalent measuring device, to
establish initial conditions. If the main airflow must be adjusted up or down
to suit the process, repeat step 2-H above.
