Select the correct frequency using the frequency selector (13). 6. Turn on the mains switch (34). - The vacuum process will not begin until the milling unit is activated. 2.4 Electrically connecting the unit (see Fig. 3 on page 5 and Fig. 7 on page 10) 1. Connect the unit to mains (230V/50 or 60 Hz) using the mains cable included (socket (8)). 2.
/15 Thanks to the built-on power stabilizer, the preset input air volume is kept constant as the mains voltage changes (between 180 and 264 V). 3.3 Automatic turn-off and filter change indicator (see Fig. 6 on page 9). Note As soon as the filter bags (11) has been filled to the maximum permissible, an underpressure switch will actuate the automatic turn-off function, and the filter change indicator on the milling unit will be lit.
/15 Fig. 4: Removing the filter bag Caution The single-use filter bags must never be emptied and reused. Not only might this constitute a health hazard, but it would also impair the function of the unit. Caution Do not use pressurized air to remove any dust present in the filtration chamber (20). Do not allow any foreign matter to enter the air intake opening (26) because this might damage the vacuum motor. 5.

/15 3. Loosen the two nuts (28) and lift out the ledge (29) with the longitudinal holes. 4. Caution Remove the ultra-fine filter (31). No dust may be present on the sealing surfaces (24) or in the air intake chamber (32), as the dust may damage the vacuum motor (23). The air intake chamber (32) and sealing surfaces (24) must be cleaned by vacuuming. Do not use pressurized air. 5. Insert the cleaned or new ultra-fine filter (31). 6. Slide the ledge (29) onto the threaded pins from above. 7.
/15 5 Electrical protection The entire unit is electrically protected using two fine-wire fuses (main fuse) 6.3 A/T. The two fuses are located in the fuse drawer (40) inserted in the primary power socket housing (8) ist.
