2.2 Dust classes
Dust removing machines are tested according to DIN EN 60335-2-
69 and divided into dust classes.
Vacuum cleaners of dust class L are suitable for vacuuming dry,
non-flammable, hazardous dusts with a maximum allowable
concentration (MAC) of > 1 mg/m³.
Vacuum cleaners of class M are suitable for vacuuming dry,
non-flammable dusts, non-flammable liquids, wood dust and
hazardous dusts with a MAC of ≥ 0.1 mg/m³.
Vacuum cleaners of class H are suitable for vacuuming dry,
non-flammable dusts, carcinogenic and pathogenic particles as well
as non-flammable liquids, wood dusts and hazardous dusts with all
concentration levels.
2.3 Intended use
The pre-separator is intended for vacuuming large quantities of
dust. It separates a large part of the matter from the suction stream
before it reaches the vacuum cleaner.
The hose connection is suitable for ISP, ISC and uClean series as
well as for many devices of other manufacturers.
The pre-separator is suitable for vacuuming
- dust of dust class L
- coarse dirt up to 20 mm particle size
Use only antistatic devices/accessories (earthing, protective earth
conductor must be given).
This machine is intended for commercial use, for example for use
in hotels, schools, hospitals, factories, shops, offices and rental
properties.
Proper use also includes:
- Read and understand safety instructions
- Observe operating instructions
- Observe inspection and maintenance conditions
- Observe all national safety regulations

2.4 Reasonably foreseeable use (misuse)
DO NOT VACUUM the following materials:
- dusts of dust classes M and H
- flammable or explosive solvents, including liquids such as
petrol, oil, alcohol, thinners
- substances impregnated with solvent
- aggressive materials (e. g. acid, alkaline solutions)
- chemically reactive materials, which lead to the generation of
heat, acids/bases, gases, etc. (e. g. reactive two-component
materials, aluminium and water).
- explosive dusts
- materials (shavings) hotter than 60 °C
- dust which contains asbestos
Any application other than those described in chapter 2.3 is not
permitted. This includes in particular:
- Vacuuming the materials excluded above
- Using the vacuum cleaner in potentially explosive environments
- Carrying the vacuum cleaner by the pre-separator
- Non-compliance with the operating instructions
- Use by unsuitable persons (under 18 years of age, persons
under the influence of drugs)
- Insufficient or improper maintenance and servicing
- Use of unsuitable consumable materials
The consequences of these reasonably foreseeable applications
may include:
- Fire or explosion of the vacuum cleaner and pre-separator, with
consequent risk to the operator due to burns or flying parts,
inhalation of potentially toxic substances
- When vacuuming asbestos, danger to the operator or other
persons in the vicinity through inhalation of harmful substances.
