Maintenance

8.1

Collector bin

WARNING!
Always use an approved breathing mask when replacing the dust sack.
Empty the collector bin regularly and before it becomes 2/3 full, fig. 9. If the
bin is too full it increases the load on the filters. Replace the plastic sack with a
new one (no holes) and re-connect the connection hose, see figure 10.
NOTE! Check that the connection hose is intact and not blocked.
The plastic sack is held in position in the bin by feeding negative pressure to
the outside of the sack via the hose that runs from the bottom of the bin to
the dust collector.
8.2

Changing the filter

WARNING!
Always use an approved breathing mask when changing the filter.
8.2.1

Filter package

The following filter packages are available for LPAK, see fig 14 position A - D:
(A) Filter package, PP. Replacing the entire filter package is recommended.
When only changing the socks, the filter ring should also be replaced.
(B) Filter package, cartridge
(C) Filter package, CF
(D) Filter package, sack
Change the whole filter package after about 5,000 hours of operation or a
maximum of 3 years. If welding fumes are filtered these figures should be
reduced to 3,000 hours and 2 years.
NOTE! The changing interval of the filter is dependant of the material the unit
handle. If uncertainties arise of changing intervals, contact the distributor or
Nederman.
1. Remove the top cover and the dust extractor's cover.
2. Figure 11 shows how the filter package with filter socks are removed.
3. Place the old filter package in a large plastic sack, figure 12, or wrap in
plastic foil. Avoid dust spreading.

suction capacity depreciates, placement see figure 1 position 4. Carefully lift
out the filter, place it in a plastic sack and seal the bag with care.
