DFPRE Large Dust Collectors
This way the dust will not penetrate the media and can be cleaned off as
described above. After the elements are conditioned the slide gate can be
placed back to its original position (STAGE 2 and 3).
Ensure collectors are suitably earthed.
Ensure electrical power is available.
Check fan motor for correct rotation and that the full load current is not exceeded.
(Refer to the fan rotation label located on the fan mounting plate inside the
clean air chamber).
Keep clear of inlet opening/rotating impeller whilst performing rotation
check.
To reverse rotation (single phase power supply):
Follow manufacturer’s instructions on the motor nameplate.
To reverse rotation (three phase power supply):
Turn electrical power OFF at source and switch any two phase wires on either
the motor junction box or the controller input terminals.
Ensure access panel seals are intact, then close and secure the panels.
Ensure the compressed air manifold has sufficient protection for overpressure.
Start the compressor and check that the air supply is maintained at the
recommended pressure.
Switch on the controller.
When Delta P cleaning is selected, then the cleaning system will not
operate until the differential pressure rises above a set value of 80 daPa.
If any of the above check boxes are not ticked, then the reasons why should be
investigated. (Refer to fault location table in ‘Maintenance’ section).
Ensure unit properly connected to earth using the brass screw
provided, to prevent any static build-up. (Located next to symbol
shown).
