Test the operation with the doors both open and closed. Point the nozzle away from
the door when it is tested, and only open the door enough to disengage the interlock switch.
The interlocks should stop the blasting when the doors are opened, and permit blasting
when the doors are closed.
NOTE: Negative pressure inside the cabinet may cause the doors to ex inward. Tests
should be performed with the exhauster on.
4.3.6 Pulse pressure
Adjust pulse pressure using the regulator mounted on the pulse manifold. Begin pulse
pressure setting at 4,5 bar.
When pulsing alone does not adequately clean the cartridge, increase pulse pressure
by 0,5 bar increments up to max. 6,0 bar. Increasing pulse pressure over 6,0 bar may cause
damaging of the cartridge lter.
If after pressure increasing, dust cakes on the cartridges and differential pressure
increase, adjust cycling of the pulses.
