Section 1 – Safety Recommendations

Because this unit may be under pressure or vacuum do not attempt to open any device, doors or panels while fans or blowers are running. The unit has air hoses and valves with a maximum recommended operating pressure of 100 psig. To eliminate the danger of bursting care must be taken to insure maximum desired pressure is not exceeded.
Before servicing any portion of the compressed air system the air supply must be shut off and any pressure relieved.
If your unit is equipped with a discharge auger or an airlock assure that chain guards are installed before start-up and servicing is attempted only after electrical power is locked out.
While servicing the filter it is very important that there are no open flames, welding or grinding sparks. Dust laden air could be highly explosive and extreme care must be taken. Most filter bags will burn if exposed to sparks, welding or open flames.
Before entering any dust collector:
Run cleaning mechanism 20 minutes with the fan off to clean filter bags.
Completely discharge dust solids from hopper, if applicable.
Shut off compressed air supply and relieve pressure in the compressed air
manifold.
Lock out all electrical power on all equipment especially rotating equipment.
On toxic operation, purge collector housing and install a blank in the inlet duct.
Install catwalks and safety cables as required.
Secure access doors in an open position or remove doors.
Use the buddy system.
Wear a respirator or appropriate breathing equipment.
Use common sense.
Follow all current OSHA regulations relative to Lockout / Tag-Out and Confined Space Entry and any other applicable regulations when servicing your equipment.

Section 2 - Receiving

Receiving the Equipment

Prior to accepting the shipment(s) care must be taken to inspect all equipment received both for proper count and for damage. Any and all irregularities must be noted on the carrier’s copy of the shipping receipt to assist in settling any claims for damage or shortages. All equipment is shipped FOB point of origin whether on a prepaid or collect freight basis.
ANY CLAIM FOR DAMAGE IN TRANSIT OR SHORTAGES MUST BE BROUGHT AGAINST THE CARRIER BY THE PURCHASER.
Once your claim has been filed with the carrier, contact CAMCORP to notify us of the problem(s). We will then advise the appropriate repair procedure or recommend it be returned to our factory, depending on the extent of the damage.

Inspection of the Equipment

Housing, Compressed Air Header and Timer Assembly: Particular attention should be paid to the sheet metal housing of your collector. The unit should be inspected for dents, cracks or rips. A dented housing may seriously affect the structural integrity of the unit. The compressed air header and timer assembly are very delicate pieces of the unit and must be checked carefully for any signs of impact, warpage or loose fittings. If any of these signs are present note them on the shipping receipt and notify CAMCORP immediately. The entire unit should be checked against the certified drawings for correctness. CAMCORP should be notified immediately if there are any discrepancies. No corrections may be made without the expressed written consent of CAMCORP.
Components: A count should be made of all pieces received and this should be verified against the carrier’s manifest. Boxes should be inspected for rough handling, which may have resulted in hidden damage.

Section 3 - Installation

Setting Up Your Unit

CAMCORP dust collectors are shipped either in one piece, fully assembled, or in two or more sections depending on the unit size and weight. Before attempting to move the dust collector or any of its sections review both the certified general assembly drawing supplied from CAMCORP 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 compressed air header(s), as well as the number and location of lifting lugs.
Dust collectors of this type are manufactured from steel sheets or plate 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.
The following sequential procedure will help to minimize any assembly difficulties:
STEP 1: Set up the supporting steel for the dust collector level and square. Precision at this point will greatly help facilitate erection and bolt hole alignment of the dust collector sections to follow.
STEP 2: Place the hopper with its girth channel on the supporting steel work. Check for squareness, and for bolthole alignment between the hopper flange and the girth channel. Apply the appropriate RTV silicone caulk around the periphery of the hopper flange with one bead on each side of the boltholes.
STEP 3: Lift the dirty air plenum, with the tube sheet, into place. DO NOT LOWER THE PLENUM ONTO THE HOPPER FLANGE UNTIL ALIGNMENT IS ACCOMPLISHED. The silicone caulk makes horizontal movement very difficult once a load is applied. With the plenum suspended over the hopper ½” to 1”, begin bolt hole alignment starting at the center of the plenum and working toward the ends by using tapered drift pins. If the wall(s) has flexed out of square it will be necessary to pry or pull it back into alignment. Depending on the size of the unit and the degree of difficulty hydraulic jacks and come-alongs may be required. When the mating holes are properly aligned, finish lowering the plenum. Install the remaining bolts, washers, and nuts and torque to the appropriate specifications.

Setting Up Your Unit (continued)

Step 4: Check the top of the dirty air plenum for squareness and bolthole alignment between the dirty air plenum and the tube sheet. Make sure that the silicone caulk has been applied between the top flange of the dirty air plenum and the underside of the tube sheet flange. Next, apply the caulk around the periphery of the topside of the tube sheet flange one bead to each side of the boltholes.
STEP 5: Lift the clean air plenum into place and assemble in the same fashion as in STEP 3. Again, do not lower the clean air plenum completely until preliminary alignment is accomplished. Start drift pin alignment at the center of the plenum on the compressed air header side since the header makes access to the flange more limited. When alignment is complete install the remaining bolts, washers, and nuts and torque to the appropriate specifications.
All CAMCORP dust collectors are provided with lifting lugs for ease in handling of the units during field erection and installation. The number and location of these lifting lugs will vary depending on the model, size, and weight of the dust collector. Before attempting to rig and lift your dust collector review the certified general assembly drawing supplied from CAMCORP to verify the number and location of lifting lugs as well as visually checking this information on the actual unit. Large units are frequently shipped in several sections so check the lifting lugs provided on each section. If these cannot be used or there is some question about lifting lug location consult the engineering staff at CAMCORP for proper location since proper care must be taken to prevent damage to housing or its components.
Rigging and Lifting Guidelines
Do not lift the dust collector by any attachments other than the lifting lugs provided.
Use all of the lifting lugs provided on the dust collector or a section of the dust collector when making a lift.
If the lifting lugs are located below the roofline 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.

Setting Up Your Unit (continued)

Attach tag lines at several locations to help in controlling the unit when lifted and to prevent spinning or swinging.
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.
Compressed Air Manifold: Typically, CAMCORP ships the compressed air manifold installed complete with diaphragm valves and solenoid enclosure(s), except when units are over legal shipping width with them in place.
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 ports in the dust collector not being used must be plugged prior to start-up.
Electrical: A 120 volt 60 Hertz circuit is required to operate the dust collector’s pulse-jet cleaning system (unless a different voltage for components was requested). This timer must be wired according to the wiring diagrams and be provided with a circuit that is free from transient currents. The timer has a feature called “Demand Pulse” that allows the output terminals to be energized and de-energized by the high and low set points of a differential pressure switch such as a Dwyer Photohelic Series 3000. The “Demand Pulse” terminals are marked “Pressure Switch”. Do not over fuse.
The NCC pulse timer boards have adjustable pulse duration and interval (time between valves firing) settings. Before applying power to the timer always check these settings according to the table below. Since there are many variances in operations and conditions these are presented only as initial start-up guidelines. If you experience problems in cleaning of the filter bags, please contact CAMCORP.

TIMER BOARD ADJUSTMENTS

(Recommended at start-up)
VALVE SIZE PULSE DURATION INTERVAL
¾” .10 to .12 seconds 20 to 25 seconds 1” .10 to .12 seconds 20 to 25 seconds 1-½” .06 to .08 seconds 20 to 25 seconds

Setting Up Your Unit (continued)

The firing sequence of the diaphragm valves on the dust collector should be set so that no two adjacent rows of bags fire in succession to insure maximum cleaning and life of the filter media. This can only be achieved when wiring the pulse timer board to the solenoid valves. If you are experiencing a high-pressure drop across the filter bags in your dust collector the pulse interval should be reduced.
Apply electrical power to the timer and make sure that it is cycling completely through all rows of the unit. In some cases the timer panel may have more “positions” than required in which case the position selector cable needs to be attached to the proper numerical value corresponding to the number of diaphragm valves on the unit.
If your dust collector was shipped via common carrier rather than a contract hauler there is a possibility that the solenoid enclosure was not shipped installed on the unit. If this is the case, there is a mounting plate welded on the housing or the air header with the bolt pattern of the enclosure already drilled. Bolt the enclosure and install the nylon (or copper) tubing with the fittings provided making sure that the solenoids are connected to their corresponding diaphragm valve.
Valves and Piping: After the unit has been installed the diaphragm valves should be checked to make sure that the port marked “IN” is assembled to the compressed air manifold. The “IN” connection of the solenoid valve is connected to the diaphragm valve by means of ¼” nylon or ¼” copper refrigeration tubing. Each nut on the compression fittings should be checked for tightness before the compressed air manifold is pressurized. In most cases a slip fit fitting has been used. The integrity of the nylon tubing inside each fitting should be checked by pulling gently on each tube. If the tube pulls out, simply push it back into the fitting until it will not go any further. The solenoids are shipped with a plastic plug in the discharge side of the valve. These plugs must be removed for proper operation.
Gauges: The differential pressure gauge, mounting bracket, fittings and tubing are usually shipped loose in a box with the dust collector. When installing these make sure that the high-pressure port of the gauge is connected below the tube sheet and the low-pressure port is connected above the tube sheet on the dust collector. There are pipe couplings welded on the side of the dust collector for these connections. After the differential pressure gauge is permanently mounted the gauge needs to be zeroed prior to connecting the tubing to the gauge.

Bag and Cage Installation

Installation of Bag and Cage Assembly – Bottom Loader

Inspect the filter bag cages for any signs of damage, warping, bent wires or missing welds. Inspect the filter bags for any signs of mold, mildew, ripped seams or holes.
Be sure the wire cage has a bottom pan. Slip the filter bag over the cage, centering the seam 1-½” or 2” on either side of the split at the top of the cage roll band. Seam must be straight (not corkscrewed). Make sure that the filter bag bottom is tight against the cage bottom pan.
Pull the bag up and over the full length of the cage and fold the entire extra length over and down inside the top of the cage. Smooth out any filter bag folds inside the top of the cage.
Slip the assembled filter bag and cage over the outside of the bag cup (mounted on the tube sheet) making sure to mate the male groove of the cage roll band top to the female groove of the bag cup.
If you try to move the assembly up and down you will be able to tell if the grooves are properly aligned.
Install the worm gear bag clamp on the assembly and tighten around the bag and cage at the point just above the groove on the cage. The clamp head should be located in the best position for ease in tightening.
Tighten the clamp until secure. You should not be able to rotate the bag­cage assembly by hand if it is tighten properly.
Close the access door and tighten accordingly. You are ready to begin start-up procedures if all other preceding tasks and connections are completed.
It is recommended to double check the tightness of the bag and cage assembly approximately one month after the initial start-up.

Bag and Cage Installation (continued)
Installation of Bag and Cage Assembly – Top Loader
Inspect the cages for any signs of damage, warping, bent wires or missing welds. Inspect the filter bags for any signs of mold, mildew, ripped seams or holes.
Remove the blowpipes inside the clean air plenum by loosening the bulkhead fitting on the air header end of the blowpipe and then slide the pipe out of the bulkhead fitting. Some CAMCORP dust collectors use a retaining clip on the opposite end of the blowpipe and it must be removed before removal of the blowpipe is possible.
Lower the closed end of the bag through the hole in the tube sheet and carefully feed the bag in. Assure that the bag doesn’t scrap against the sides of the tube sheet hole. Excessive scraping can damage filter bags with special coatings or finishes.
With your hands, “kidney shape” the snap band bag top in order to fit and align it within the tube sheet hole. 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 dimple. Then you can allow the band to expand and audibly snap into place.
Check the fit of the snap band in the tube sheet hole. It should be even in height above the tube sheet around the entire circumference, which will confirm to the installer that the filter bag is centered and well secured in the tube sheet.
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.
Replace the blowpipes in the opposite order stated above. Make sure that the orifices in the blowpipes are properly oriented to blow straight down the center of the bag and cage assembly before tightening the bulkhead fitting.
Replace access doors and tighten accordingly. You are ready to begin start-up procedures if all other preceding tasks and hook-ups are completed.
