5 Applications and techniques
5.1 Techniques If used correctly, additional ac-
cessories, suction nozzles and
suction hoses can enhance the
cleaning action and reduce the
cleaning effort. Effective cleaning is achieved if
you follow just a few guidelines
in combination with your own
practical experience in special
fields.
Here are some basic tips.
5.1.1 Picking up dry
substances
CAUTION:
Do not pick up flammable
substances.
The suction hose diameter must
suit the position of the switch in
order to pick up dry, nonflam-
mable dust with maximum room
concentration values.
There must always be a safety
filter bag in the tank before dry
substances with maximum room
concentration values are picked
up. See section 9.5 “Accesso-
ries” for ordering number.
To pick up harmless dust we
recommend the use of a waste
bag. See section 9.5 “Accesso-
ries” for ordering number. Dis-
posal of the picked up material
is then simple and hygienic.
After picking up liquids, the filter
element is wet. A damp filter el-
ement clogs more quickly when
dry substances are picked up.
For this reason the filter element
should be washed and dried or
replaced by a dry element be-
fore dry substances are picked
up.
5.1.2 Picking up liquids CAUTION:
Do not pick up flammable
substances.
Before liquids are picked up, al-
ways remove the filter bag/waste
bag and check that the float (IVB
3-H) or the water level limit (IVB
5-H/7-H) works properly. (See
section 7.2.3 and 7.2.4 “Replac-
ing the filter element“.)
The use of a separate filter ele-
ment or filter screen is recom-
mended.
If foam appears, stop work im-
mediately and empty the tank.
To reduce the amount of foam,
use foam killer Nilfisk-Advance
Foam Stop (see section 9.5
„Optional Accessories“ for order
number).
