Bulk-bags and holders

Certain Ex products are equipped with bulk-bag holders for collecting material.
Other collection methods may be used if the system risk analysis finds them to
be safe.
NOTE! Always use
approved bulk bags.
Place a bulk bag on a pallet and position it under the bulk-bag holder. The
buckle on the bulk-bag holder secures the bulk bag opening to the holder, see
Figure 7(A).
Connect the bulk-bag corner straps to the chains on the bulk-bag holder. Adjust
the tension by moving the quick link up or down the chain, see Figure 7(B).
NOTE! Do not hang bulk bags by their corner straps. Straps are only intended
to keep the bag from collapsing. The weight of the collected dust/material must
be supported by the pallet, see Figure 7(C).
NOTE! Connect the upper and lower ground wires to the bag.

Earth control measurement

Check for proper earth connection after both main installation and regular
maintenance work. If a component, such as the top module for example, is
removed and refitted, earth connection must be verified.

Use

• Do not use vacuum cleaner to collect material that is caustic, hot, explosive,

• Make sure compressed air pressure is between 6 and 8 bar.
• Turn off vacuum cleaner if liquid, dust or foam escapes from it.

Vacuuming

1. Connect the compressed air hose to the ejector top.
