NOTE! The service intervals in this chapter are based on the unit being professionally
maintained.
The collecting bin should be emptied before the plastic sack is 2/3 full. The option FBA
(Filter and Bin Alarm) gives an alarm at this level. Before emptying, with the vacuum unit
still running, manual filter cleaning should be released a couple of times by depressing the
button "Manual function" on AFC-B / AFC-RF. Then stop the vacuum unit and remove the
bin, Figure 14, and put in a new sack. Do not forget to re-attach the pressure equalisation
hose, Figure 15. Otherwise the plastic sack will burst due to atmospheric air rushing in
underneath the sack when the vacuum unit starts up again. Check the dust quantity
frequently during the first weeks of operation to establish suitable intervals between
emptyings. The interval can vary from once a day to once a month.
Check regularly, when emptying the dust bin, that there are no large amounts of dust on
the outside of the filter socks. This is done from below, when the bin has been removed.
Rags, paper or fluffy material that may have snagged on the socks should be removed by
hand.
WARNING!
A protective mask, goggles and gloves are to be used when emptying the dust bin, when
changing filters or whenever exposure to dust may occur.
The filter socks should be replaced after 6,000 to 8,000 hours of operation. Large amounts
of welding fumes or oil mist can make more frequent changes necessary. The Nederman
High Vacuum Starter is fitted with a service hour meter for recording service hours.
Replacement of filters should be registered on the installation service card.
Individual replacement of filter socks is possible but replacing the whole filter package
including filter holder and locking rings is recommended. The job takes less time and causes
less spreading of dust. The job is facilitated if the dust collector is placed so that it can be
tilted, see Figure 16. (Not all models can be tilted.)
NOTE! If filter socks are replaced individually their plastic locking rings must also be
replaced.
Figure 17, items A–C, show how the rubber sealing rings and the steel retainer rings should
be assembled. When a used sealing ring is re-fitted it does no longer have the open shape
shown in Figure 17, item A, but the ring is more closed. A screw driver may be used to
bring the edge of the module between the rubber lips giving the end result, after the steel
ring has been fitted, shown in Figure 17, item C. Correct assembly is essential for the dust
collector to maintain its strength and to stay leak-free.
