2.1 Intended use
Vacuum medium The wet separator can be used for vacuuming up dry, wet, hot,
smouldering and explosive media which may be either fine or
coarse, and for feeding back filtered air into the working area.
The wet separator is classified according to the dust classes
specified in IEC / EN 60335-2-69 and may be used to vacuum up
only dusts within the respective workplace limit values for the dust
concerned. See page 13.
To comply with the terms of the intended use, the following
measures must be complied with:
The definition of intended use given here includes reading this
instruction manual and following the instructions given in the
manual, in particular the safety precautions.
Safety devices must be serviced regularly and their correct
operation to the required safety standards checked at least
once a year.
The wet separator may only be used in industrial areas.
The wet separator may be operated only above ground.
The wet separator may be used exclusively within the
performance limits listed in section “Technical Data” on
page 27.
All inspection and maintenance operations must be performed
at the specified intervals.
The safety data sheets for the media being vacuumed up must
be complied with.

2.2 Improper use
No changes, attachments or conversions that may influence
safety may be made to the wet separator. This also applies to
installing and adjusting safety equipment and valves.
The wet separator must not be located in areas that may have
a potentially explosive atmosphere.
The stickers that are affixed may not be removed.
Damaged or illegible stickers must be replaced.
The wet separator must not be used to supply air to containers
or extract air from them.
The wet separator may be used at full vacuum only for short
periods. Longer operation at full vacuum may lead to damage
to the vacuum pump.
The wet separator must not be operated without the sealing
liquid / swirl filter / moisture separator / filter cartridges.
The wet separator must not be used to vacuum up any liquids.
The wet separator must not be operated with blocked vacuum
hoses.
The vacuuming up of objects of dust classes M and H is
permissible only if a flow velocity of at least 20 m/s is
maintained in the vacuum hose.
Never use any spare parts other than those on the Ruwac
spare parts list.
If combustible materials or reactive materials are vacuumed
up, the wet separator may be operated only when it is
equipped with effective potential equalisation and electrically
conductive vacuum accessories.
The vacuum hose of the wet separator must not be laid or
wound around the shoulder(s) or the upper part of the body.
Bodily contact with the vacuum hose must be kept to a
minimum. The vacuum hose may be guided with the hands.
