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.
