Cleaning the Membrane Filter during Operation
(as needed, or when the alarm beeps)
Block the intake / hose so that full vacuum is made in the machine.
Repeat the steps 1-3 approx. 2-3 times when cleaning.
The difference in pressure / the shock effect will clean the surface of the filter, when air is drawn through the valve
in order to equalize the negative pressure in the collection container and the hose, and will reject possible
deposits from the pre-filter and release collected media from the inside surface of the collection bag.
This method gives an effective cleaning of the pre-filter / membrane filter.
We recommend to always leave the machine for a few minutes before emptying it. The dust will fall to the bottom
of the collection bag, and the risk of swirling dust into the surroundings during the emptying is reduced.
If
–
by mistake
–
the machine has been used without collection bag, use PPE when emptying the machine.
NOTE: Do no
t ”tap” on the intake as this will swirl up the dust in the container and result in blocking of the
pre-
filter and damaging the collection bag.
1.
Block the intake / Block the
hose.
Take hold of the flap of the
shock valve.
2.
While the machine is blocked
and running, pull the flap of the
shock valve (do not tug the
valve).
3.
When the power grows bigger
than the influence from the
vacuum, the valve will
automatically open with a
“
puff
”
. Let go of the valve.
