Section 3 - Installation ( !, +0! 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.
( !, +0! 3 + 24 Step 4: Platform and ladder, if applicable, can now be attached. Torque the fasteners 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.
( !, +0! 3 + 24 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. Flanges: All bolts on flanges should be tight. All ports in the dust collector not being used must be plugged prior to start-up.
( !, +0! 3 + 24 The firing sequence of the diaphragm valves on the dust collector should be set so that no two adjacent rows of cartridges fire in succession (if possible) 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. Apply electrical power to the smart timer and make sure that it is cycling completely through all rows of the unit. This will only happen when the smart timer is put into manual mode.
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. 3-5 CAMCORP, INC. Phone: 913-831-0740 Fax: 913-831-9271 www.camcorpinc.
• • • Open the access door on the dust collector. Depending on the size of your dust collector, there are a number of rails or carriage assemblies attached to the bottom of the tube sheet for the filter cartridges to be support from. The handle levers for each rail should be pushed forward, which lowers them and allows the filter cartridges to be either installed or removed. 3-6 CAMCORP, INC. Phone: 913-831-0740 Fax: 913-831-9271 www.camcorpinc.
• • • • The filter cartridges have a metal mounting flange around the top of them. If the dust collector requires over bags, they should be installed before installing the filter cartridges into the dust collector. Pick-up the filter cartridge(s) and slide the metal pan over the top of the lowered rails of the carriage assembly. Be careful not to damage the filter media when handling them. Push the cartridges toward the back of the dust collector as far as possible. 3-7 CAMCORP, INC.
• • • After the filter cartridge(s) are all slid in, grab both lever arms and pull forward. Be careful again to not damage the filter media. The levers will raise the filter cartridge(s), making them seal against the tube sheet. Reverse this procedure to uninstall the cartridges. 3-8 CAMCORP, INC.

Section 6- Troubleshooting 0 +95 .) ( ) %+. 55 0 Excessive Pressure Drop Across Filter Cartridges The differential pressure gauge or manometer on your dust collector should read 6” w.g. or less. Higher readings and/or steadily increasing readings are an indication that the main airflow through the dust collector may be restricted and a potential process problem such as poor suction at duct pickup points may exist. In extreme cases (over 17” w.g.) filter cartridges will be damaged.

Section 7 – Routine Maintenance Inspection Frequency will vary as widely as there are operating conditions. general proceed as follows: In Daily – Check unit differential pressure. Weekly – Check pulse timer board and solenoid valves for function. This usually is only listening to verify uniform time in intervals between blasts. Monthly – Lubricate fan, rotary valve and screw conveyor. Check seals on latter two for dust loss.
Section 8 – Appendix Dust Collection Terms & Definitions Air-to-Cloth Ratio – Ratio of the volume of gas filtered (in ACFM) to the amount of filter media (in square feet). Cartridge Blinding – A condition where dust particles become embedded in the fabric over time and are not removed by the cleaning mechanism. This results in an increased pressure drop across the filter cartridge media. Bleed Through – Small particles of dust that are able to migrate through the filter cartridges.
Pressure Drop – Another term for differential pressure or the drop in pressure between two measured points. Re-Entrainment – The re-depositing of dust on the filter media after it has been cleaned off. This can be caused by turbulence in the hopper (or dirty air plenum) or by excessive airflow through the dust collector. Solenoid Valve – In the case of a dust collector, a solenoid valve is used to open and close a diaphragm valve.
