Std. Outlet A B B B Inlets Figure 2 1.4 The Millennium - A Description The standard Millennium collector comes in 14 basic sizes. The size variations are composed of combinations of either 96 bag or 144 bag modules, with one to five modules per unit. The Millennium will use 5 1 4 " diameter bags in a 7" x 7" spacing pattern. Bag lengths of 8, 10, 12, and 14 ft. are available. Standard module combinations are listed below. The 96 bag modules are indicated as “96” and the 144 bag modules as “144”.

Pulse Pipe Clean Air Plenum Solenoid Valve Air Hose Diaphragm Pulse Valve Figure 3 tank/pulse pipe assembly. Each pulse valve serves twelve bags. Pulse pipes are 1 1 2 ", schedule 40 pipe and have a quick disconnect coupling and a pinned end. Standard collectors are primed and finish painted on the exterior with high solids alkyd enamel. Interior surfaces have a prime coat. High temperature collectors have one coat of zinc rich primer. Special paint coatings are available as an option.

Bolt Hole The access ladder assembly is complete with a safety cage and mounting brackets. Bolt (or weld) the ladder to the collector housing, as shown in the installation drawing. The ladder assembly has mounting brackets which attach to the housing and to the hopper/housing flange. Ladder mounting brackets may be bolted (or field welded) to the collector. 3.6 Electrical Controls and Wiring Sealant Bead Housing or Hopper Flange Figure 4 5.

CAUTION: To avoid permanent damage to the solid state control: 1. DO NOT connect 120V to the “PS” terminals. 2. DO NOT connect 120V to any of the “Output” terminals. 3. DO NOT connect an “Output” terminal to ground. The fuse on the panel does not protect from a direct short. Power should be supplied to the solid state timer board across terminals L1 and L2 as shown on the connection diagram. When the power is energized, the “Power On” light should illuminate.

For Initial Installation or Service Tube Sheet 1. Open roof doors for access to bags (see Section 3.9). Pulse Hole See Step 2a 2. Remove pulse pipes as follows: a. Loosen the bulkhead coupling to allow the pipe to slide out. b. Remove hairpin from the opposite end of the pipe. c. Lift the pulse pipe assembly to clear support pin and slide the pulse pipe away from the supply pipe until it has disengaged. Lift and remove. Pulse Pipe Support 3. If performing service: a. Remove cage/venturi assembly.

4.0 Initial Startup Instructions 4.1 Preparation for Startup 1. Check the compressed air lines to ensure they are properly connected to the manifold. Turn on the compressed air supply and adjust the pressure to 80 to 100 psig. BEFORE PULSING, CONDENSATE BLEED VALVES SHOULD BE FULLY OPENED TO PURGE AIR LINES AND MANIFOLDS OF DIRT AND WATER. GOOD PRACTICE DICTATES THAT ALL PIPING BE BLOWN DOWN TO REMOVE ANY SCALE, RUST OR OTHER DEBRIS PRIOR TO PULSING THE UNIT.

the dust on the outside surface of the individual filter bags. The cleaned air leaves the filter bags and discharges into the plenum at the top of the collector, where it is then exhausted through the outlet. The filter bags are periodically cleaned by bursts of compressed air that are directed down the inside of the bags. A venturi located in the top of the bag cage induces additional air to the inside of the bags being cleaned.

7.2 Visible Discharge 1. Improperly Installed or Damaged Bags Check for holes or tears in bags. Replace damaged bags. Reseal bags as necessary. 2. Insufficient Dust Cake The unit could be pulsing too often, resulting in over cleaning. Verify the pressure drop is at least 2" w.g. Increase the pulse interval until the unit is operating stably at 2" pressure drop minimum. CAUTION: Do not adjust the pulse duration without consulting an AAF representative. 7.3 Insufficient Hood Control 1.
