Visual and Operational Checks
Check for any visual alarms on top of cabinet
Record Differential Pressure (dp) from magnehelic gauge
Meter name
Unit
Is the Differential Pressure within the nominal operating range of 0.6kpa to 1.1kpa?
Inspect and record Hopper Temperatures
Inspect and Ensure Hopper heating element is working correctly
Check inside walls of hopper is clean, and there is no build up.

Inspect and record No. 1 Plummer block bearing Temperature
Meter name
Unit
Inspect and record No. 2 Plummer block bearing Temperature
Meter name
Unit
Inspect and record Electric motor Temperature
Meter name
Unit
Grease bearings on fan bearing blocks, check level in lubricator if fitted.
(Electrician only) Check condition of main control panel wiring, and components.
Trigger the pulse valves are controlled to fire when DP reaches the high set point, and turn off when DP reaches low set point. To trigger the firing, move the upper set point (red) needle on the magnehelic down to below the black needle, after pulse firing is proven, move the set point needle back to its original position.
Compressed Air System
Record compressed air pressure
Meter name
Unit
Check compressed air system for leaks and organize repair if required
Check compressed air filter trap and drain water if required
22. Inspect Compressed Air dryer to ensure system is working correctly.
Drum and Material Handling
Check drums for moisture and level, replace if required
