Start-up sequence

2. Check that the compressed air supply is maintained at the recommended
pressure.
3. Adjust the slide gate as described in commissioning.
4. Switch on controller.
Shut-down sequence
At the end of any period of operation it is most important that all residual
deposits are cleared from the filter cartridges, casing, and discharge hopper.
To achieve this, equipment should be shut down in the following order:
1. Stop fan only, leaving controller and compressed air supply switched on to allow
filter to be cleaned ‘off-line’.
To enable off-line cleaning, see controller manual.
2. After 10-15 minutes, switch off controller and the compressed air.
Where the dust being handled has self-heating properties, it is important to
remove any deposits in the dust container to reduce the risk of an explosion.
Adherence to the above procedure will ensure that the dust collector installation is
maintained at optimum efficiency.
