Prior to operational use switch on the extraction fan and make sure that the installation is
functioning properly.
7. Operational Use
Low displacement resistance of the suction trolley and easy manoeuvring with the extraction
arm provide a convenient use of the whole extraction system. By means of the shut-off dam-
per lever, adjust the volume flow of the extracted air, in a way that efficiently eliminates the
fume and dustiness, not causing excessive draft.
During the operational use, the position of the extraction arm and of the shut-off lever can be
changed several times adapting the system to the current needs of User.
Having completed the work close the shut-off damper (in the suction hood), as this will impro-
ve the suction capacity in the second extraction arm.
One suction duct provides operational space for simultaneous function of two extraction arms.
Adjustment of the brakes (in the arm joints), ought to be performed according to the individual
instructions of the subsequent extraction arms.
8. Troubleshooting Guide
