DFPRE 4 Dust Collectors
COMMISSIONING
It is a requirement of the Supply of Machinery (Safety) Regulations 2008 to
provide adequate isolation and emergency stop facilities. Due to the varied
nature of site installations this cannot be provided by Donaldson but instead
is the responsibility of the customer.
Before putting the dust collector into service the following items should be checked.
Similar checks, as appropriate, should be made after any major overhaul.
Commissioning check list
Where applicable, ensure that the collector is securely bolted to the floor.
Ensure dust disposal system is correctly installed.
Ensure all ducting is complete, all detachable panels are in position and fixed
guards are secure.
When new filter elements are installed it is necessary to reduce the airflow
through the filter media by partially closing the slide gate.
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.
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).
