(ATH 3-12 and ATH 4-128 shown below)
4. INSPECTION
4.1 Upon receipt of unit, the collector and any optional components must be checked for damage or potential loss incurred during shipping. Damage must be noted on the bill of lading and a claim filed with the carrier immediately. Clean Air Industries should be notified immediately upon receipt of unit, regarding any missing/lost items/components/parts. 5. THEORY OF OPERATION 5.1 The ATH dust collector is designed to enhance the air quality for plant personnel. During normal operation, air flows through the duct and into the collector plenum. An abrasive inlet is available as an option. Dirtied air moves between and into the cartridge filters, and subsequently towards the blower. A portion of the dust will collect on the surface of the cartridge media as the air passes through the filter media, and into the blower. The dust that collects on the cartridge media will periodically be dislodged by the reverse jet pulse cleaning system. This system is electronically controlled and is usually configured to monitor the differential pressure between across the filter media. When the differential pressure reaches the adjustable set point, a brief burst of compressed air will be released into the core of the cartridge filter to dislodge the dust from the filter surface. The dislodged dust gradually migrates towards the settling chamber for subsequent removal through the hopper.

6. FEATURES
6.1 Standard
6.1.1 FIRE RETARDANT CARTRIDGE FILTERS – The filters have been treated with a chemical to “retard” against chemical combustion; however, the cartridge filters are NOT “fire proof”, th at is, under certain the filters will combust.
6.1.2 METAL CONSTRUCTION – The unit is constructed of 7 and 11 gauge carbon steel. This fabrication technique results in a robust unit capable of withstanding the rigors of reverse jet cleaning.
6.1.3 REVERSE JET CLEANING – The unit is equipped with a compressed air manifold and 1" valves which upon activation by the pulse control box, opens the valve and delivers a short burst of air into the clean side of the filter. The temporary reverse flow of air dislodges accumulated dust on the filter which slowly migrates towards the settling chamber. 6.1.4 TURBO DIGITAL PULSE CONTROL – This electronic device constantly monitors the differential pressure across the cartridge filters and, when the programmable set point is met, automatically reverse pulse cleans the cartridge filters. The unit also offers a cycle down feature, whereby the filters are cleaned on shutdown. 6.2 Optional 6.2.1 AFH/AFS - After filter housings are available with either HEPA or Safety filters. HEPA filters are 99.97% efficient at specified flow/pressure rates and Safety filters are 95% efficient at specified flow/pressure rates.
6.2.2 DRUM LID KITS – Drum lid kits provide an "air tight" connection between the 14" opening on the hopper and 5, 10, 20, and 55 gallon drums.
6.2.3 FIRE SUPPRESSION – Fire suppression is available in a variety of technologies. Fire suppression systems should be installed by qualified individuals and in accordance with any local, state, or national codes/regulations/laws (if any). 6.2.4 HOPPER ACCESS DOOR – Hopper access doors provide an avenue for quick entry into the bottom of the collector. This option is most helpful when bridging of material is problematic or frequent access is necessary. 6.2.5 PNEUMATIC VALVE KIT - A pneumatic valve kit includes a pressure regulator, coalescing filter, and pressure gage. This kit helps insure that clean dry air is being supplied to the pulse valves at the proper air pressure. NOTE: The coalescing filter requires periodic maintenance/replacement (life span is a function of supplied air quality). 6.2.6 RUPTURE PANELS – Explosion/rupture panels are available for all units for combustible dusts with a Kst of less than 200 (8 bar Pmax). An Explosion Vent is designed to relieve rapid pressure build up, as is experienced from a deflagration within the dust collector. If your rupture panel should experience a burst, then contact your Clean Air Industries Distributor to order a replacement. 6.2.7 SLIDE GATE – The slide gate option allows for continuous operation when emptying the contents of 5-55 gallon drum dust containers.

6.2.8 SILENCER - Silencers are manufactured from 11 and 14 gauge carbon steel. The silencers are lined with a minimum of 3” of a sound damp ing material.
6.2.9 SMOKE DETECTION – Smoke detectors are available in a variety of models. Smoke detectors should be installed by qualified individuals and in accordance with any local, state, or national codes/regulations/laws (if any). 6.2.10 SPRINKLERS - Unless otherwise requested, the sprinklers discharge at 165 o F. Sprinklers must be connected to the plant’s main sprinkler system and in accordance with any local, state, or national codes/regulations/laws (if any).

7. INSTALLATION
7.1 Initial Considerations
7.1.1 The location of the unit(s) must be planned to maximize effective operation and simultaneously afford access for service/maintenance, while keeping safety considerations at the forefront. Explosions and fires in collection systems are possible; therefore, systems should be designed and placed with those two aspects in mind and in accordance with any local, state, or national fire/safety codes/regulations. Thought should also be given to electrical and compressed air sources, keeping in mind that the collector will need to be connected with electricity, compressed air, and fire detection/suppression systems (optional). Should additional questions arise or assistance is needed consult your Clean Air Industries distributor.
7.1.2 After the installation, access/clearance must be available to service the following
components:
1. Filters 2. Fan 3. Valves 4. Controls 5. Dust drums
7.2 Mechanical
NOTE : All of th e m echanical i nstallation m u st be p erformed b y a qualified in staller an d in ac cordance w ith loc al, state, an d n ational c odes/regulation s/laws ( i f an y). 7.2.1 The ATH series unit is a factory assembled dust/smoke collector. Placement/movement of the unit inside the factory/building is usually the major concern. Ensure you have enough room in front of the access doors and/or dust drawers for easy filter access as well as all around the unit for access in the event of maintenance or emergency.
7.2.2 After placement the collector should be secured to the floor using tapered anchor bolts (optional).

NOTE: Should questions arise concerning total weight, consult your Clean Air Industries Distributor or Clean Air Industries Factory. 7.3 Electrical NOTE : All of th e e lectrical installation m u st be p erformed by a qualified e lectrician an d in ac cordance w ith loc al , state, an d n ational codes/regulation s/laws ( i f an y). 7.3.1 The blower motors are typically configured to operate with 208-230/460 volt, 60 cycles, and 3 phase electrical power, unless specified otherwise with the equipment order. A magnetic motor starter with overload protection is necessary to properly energize (electrically) the unit. The voltage (and full load amps), for which the motor is configured, should be labeled on the electrical connection box. Electrical connections to the box (and wiring) must be sized and selected in accordance with local, state, and national codes.
7.3.2 Nominal Full Load Amperes are as follows:

7.3.3 Proper rotation for the blower should be noted on the blower housing. If the blower is running in reverse, the air volume will be approximately 50% of the designed air volume and excessive noise will be generated. Therefore, once the motor is wired, check motor rotation by energizing the blower motor for a brief instant (“JOG”). If direction is incorrect, then adjust by switching two (2) of the 3- phase connections on the output side. 7.3.4 If your unit is equipped with the “ Turbo Digital Pulse Control ” , then this feature will need to be connected to a 120 volt power source. Power consumption is less than 50 Watts. The pulse control unit also monitors filter differential pressure and will require pneumatic hoses to be connected. On the right side of the collector (if you are looking at the filter access doors) are 2 ports for connecting the hose. They should be labeled “HIGH” (" dirty " side - closest to the front of the collector) and “LOW” (" clean " side - closest to the rear of the collector). On the pulse control enclosure are 2 ports currently labeled “dirty” and “clean”. Inter - connect these ports with air tight tubing.

NOTE : Th e digi tal r ever se jet pul se controlle r wi th “Pul se o n Shu t down” featur e mu st b e wire d wi th a continuous 115 volt supply. The control must not be wired in parallel with the fan motor starter. (Exception is when using an Amtech combination motor starter with disconnect as this has a dedicated 115V transformer.)
7.4 Compressed Air
NOTE : The compressed a ir in stallation sh ould be p erformed b y a qualified in staller an d in ac cordance w ith loc al, state, an d n ational c odes/regulation s/laws ( i f an y). 7.4.1 Compressed air is used to clean the dust coated cartridge filters with a high pressure reverse jet pulse. A one inch diameter dedicated supply with a minimum of 80 PSI and a maximum of 100 PSI is recommended. An air regulator may be necessary to step down the supply air if the plant pressure is above the recommended rating. Failure to lower the inlet air pressure to the manifold will result in component damage. 7.4.2 The air supply line to the accumulator tank must include water, oil and particulate filtration. Water and especially oil in the compressed air will significantly reduce the effectiveness of the reverse jet pulse cleaning by contaminating the cartridge filters and causing excessive differential pressure across the filters, which results in greatly reduced air flow along with premature filter replacement. 7.4.3 A high pressure gage has been pre-installed to monitor air pressure at the manifold. Prior to the final connection of the air line to the collector manifold, the air line should be purged. This will help remove debris that could damage the valves and block the nozzles in the blow pipes. NOTE : Failure t o purge t he air li ne afte r an in itial in stallation, c ommonly o ccur s an d resul ts in d ecreased cleaning ac tion o f th e c ollector. NOTE: The compressed air so urce must be fr ee of o il ( and water ). Oi l ( and w ater ) will cau se premature fai lure of the cartridge fi lters.

7.5 Smoke Detection/Fire Suppression (OPTIONAL)
NOTE : All of th e smoke d etection/fire su ppression installation m u st be performed b y a qualified technician and in ac cordance w ith loc al, st ate, an d n ational c odes/regulation s/laws (i f any). 7.5.1 Smoke detection and fire suppression is an important aspect of the installation procedure. Fires are a common occurrence in dust collection systems and the comprehensive collection system should be designed for when a fire occurs, not if. Various systems are available for smoke detection and an even greater list of fire suppression technologies exist. Fire sprinkler systems for collectors MUST be properly connected. In most cases, this is the closest building’s fire sprinkler system. ALL smoke detection/fire suppression systems should be periodically inspected and maintained. 7.6 HEPA/SAFETY FILTERS (OPTIONAL)
7.6.1 Prior to attaching the HEPA/SAFETY housing to the exit end of the blower or silencer, apply silicon sealant to the mating flanges.
7.6.2 Insert and hand tighten the supplied bolts to secure the assembly.
7.6.3 After all bolts have been “hand tightened”, then “snug” the bolts. DO NOT OVER TIGHTEN!
7.6.4 The HEPA/SAFETY filter assembly is generally shipped with a protective cover. If so
supplied, remove the protective cover before energizing the system.
8. PRE-START UP 8.1 If not already verified in the electrical section, check rotation of fan by electrically energizing the system (turning the electrical power “ON” for a brief instant), and verify rotation. Rotation must be consistent with labeled direction on the blower.
8.2 It is suggested that new filters be properly pre-conditioned with pre-coat before start up. Please contact your Clean Air Industries Distributor for assistance.
8.3 Check the compressed air system for leaks. Confirm 80 PSI minimum air pressure (maximum 100 PSI).
Warning : Compressed air p ressure h igher t han 100 PSI can d amage t he fi lter s an d t he d u st collector’s structural integrity.
8.4 Check that the compression couplings of the pulse valves are tight.
8.5 Manually activate the reverse cleaning valves (from the Turbo pulse cleaning control). NOTE: The sound of a properly function valve is very loud (almost like a "shotgun").
8.6 Check each valve for leaks. NOTE: It is normal (and expected) for the bleed air port (on the pulse valve) to release a distinctive burst of air with each pulse.
8.7 Check the adequacy of air supply by assuring no less than 35% drop in pressure during pulse.

9. START UP
9.1 Apply compressed air to the manifold.
9.2 Energize (push the "START" button) the main blower.
9.3 Energize the Turbo Digital Pulse Control (reverse jet pulse control), if so equipped.
9.4 Energize other auxiliary equipment, as required.
9.5 COMMENTS REGARDING FILTER DIFFERENTIAL PRESSURE DURING OPERATION:
9.5.1 Depending on operating conditions, reaching equilibrium for filter differential pressure may vary from a few hours to several weeks. Low dust loading will normally develop 1-2 ” w.g., normal loading typically generates 2-5 ” w.g., and high loading varies from 5 - 10 ” w.g. 9.5.2 Low dust loading typically shows a steady level of differential pressure with very little fluctuations once equilibrium is reached. By contrast, heavy loading can produce significant “Ups and Downs” in operating differential pressure. 9.5.3 If your unit is equipped with the programmable pulse control, then it is usually necessary to gradually (over a period of weeks or months) raise the high and low set points to reflect the normal buildup on the filters. 10. SHUTDOWN 10.1 De-energize (push the "STOP" button) the blower motor. The digital reverse pulse cleaning systems are equipped with an “ Off Line Cleaning ” feature which activates the reverse jet pulse cleaning. This element will clean the filter cartridges while the unit is off line, for a preset number of pulses to each valve (usually 5). Once the cleaning cycle is complete the collector is ready to be energized when needed.
10.2 Secure power to the digital reverse pulse control.
10.3 Secure power to the lights, and other auxiliary equipment.
CAUTION: Of f l ine c leaning c an c au se pressure w ave s t o fe ed b ac k through system . Pr ecaution s m ay b e necessary to p reven t bac k dusting.
