• Apply silicon sealant to the top portion of the AutoVent collector (where the top outlet panel/HEPA/SAFETY afterfilter assembly attaches). • Place the top outlet panel/HEPA/SAFETY afterfilter assembly on top of the main unit (align the bolt holes). • Insert and hand tighten the supplied bolts to secure the assembly. • After all bolts have been “hand tightened”, then “snug” the bolts. DO NOT OVER TIGHTEN!
8. PRE-START UP
8.1 If not already verified in the electrical section, check rotation of fan by tur ning “ON” for a brief instant (JOG) and verifying rotation. Rotation must be clockwise when viewed “OVER THE MOTOR” from the discharge side. If the rotation is correct, start the motor.
8.2 Check the compressed air system for leaks. Confirm 90 PSI minimum air pressure (maximum 100 PSI).
Warning: Compressed air pressure higher than 100 PSI can damage the filters and the dust collector’s structural integrity.
8.3 Check that the compression couplings of the pulse valves are tight.
8.4 Manually activate (if so equipped) the reverse cleaning valves.
8.5 Check each valve for leaks. NOTE: It is normal for the bleed air port to release a burst of air at each pulse.
8.6 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) for the main blower.
9.3 Energize the Turbo Digital Pulse Control (reverse jet pulse control).
9.4 Energize the 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 2- 3” w.g., normal loading typically generates 3-6 ” w.g., and high loading varies from 6 - 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 s ignificant “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.
