A 3 Operation
When EWL products are operated for
the first time and for every operation
thereafter, it is essential to note the points
mentioned in the section «
A 1.3 Safety
measures
» !
Put central extraction system into operation.
Switch on supplementary control at mains
switch @.
ithout external signal transmitter and
without external sealed keypad
(automatic mode)
When the dust-generating consumer is put
into operation, the suction path is opened.
When the consumer shuts down, the suction
path is closed after a set after-running time.
ith external signal transmitter and
without external sealed keypad
When the signal transmitter is actuated (e.g.
with the foot switch , the suction path is
opened. At the end of the actuation of the
signal transmitter (switch , the suction path
closes after expiry of an after-running time
set on the ABSORmatic plus. The switch-
on state of the dust-generating consumer
has no effect on the suction path.
ith external sealed keypad on the
workstation
” Automatic / Continous
Automatic mode: When the dust-gene-
rating consumer is put into operation,
the suction path is opened. When the
consumer shuts down, the suction path
is closed after a set after-running time.
Continuous operation: The suction
path is opened regardless of the dust-
generating consumer.
ith external sealed keypad and exter-
nal signal transmitter
” Signal transmitter / Continous
When the signal transmitter is actuated
(e.g. with the foot switch , the suction
path is opened. At the end of the
actuation of the signal transmitter
(switch , the suction path closes after
expiry of an after-running time set on
the ABSORmatic plus. The switch-on
state of the dust-generating consumer
has no effect on the suction path.
Continuous operation: The suction
path is opened regardless of the dust-
generating consumer and of the external
signal transmitter.

A 4 Maintenance
■
Repair and maintenance work on the
electrical part of the unit may be performed
only by qualified specialists or trained
persons who have been made aware of the
safety regulations. For maintenance work,
disconnect the mains plug or isolate the
unit completely from the mains supply,
thus cutting off power to the unit.
The supplementary control and the suction
path diverter require no special maintenance.
At regular intervals, check the connections
of the suction hoses and compressed air lines
for leaks.
A 5 Malfunctions
Repair and maintenance work on the
electrical part of the unit may be
performed only by specialists or persons
who have been trained in the factory and
have been made aware of the safety
regulations. Before opening housing parts,
disconnect the mains plug or isolate the
unit completely from the mains supply,
thus cutting off power to the unit.
C• Owing to soiled protective filter £,
insufficient vacuum or no vacuum in the
compressed air lines #
R• Clean or replace protective filter £.
C• Compressed air line fi kinket
R• Check compressed air line and if
necessary replace.
C• Insufficient inlet air pressure via the
supplementary control.
R• Check air pressure on manometer ”
and if necessary set to 0.8 bar on adjusting
wheel @. Check inlet air pressure to
supplementary control.
C• Rubber membranes of suction path
switching systems or suction path diverter
faulty.
R• Replace suction path switching systems
or suction path diverter (see replacement
parts
F=Fault C= Cause R= Rectification
F• Suction path switching system or
suction path diverter does not close £

The installation is performed in two
steps:
B 3 Installation of the single suction path
switching system (or optionally of the four-
fold suction path diverter and connection of
the suction hoses.
B 4 Installation of the supplementary
control.
Connection of the individual components.
B 3 Installation of the suction path swit-
ching system
Installation location
The single suction path switching system @
is installed between the dust collection point
and suction line of the central extraction
system.
Use screw socket ” (optional if necessary.
Installation of the suction path diver-
ter (optional
Installation location
Install the suction path diverter under the
bench on a technician's workstation.
The mobility of the Bunsen burner
tubes must not be restricted by the
installation of the suction path diverter and
the suction hoses.
Install the mounting bracket in a suitable
place under the bench as shown.
Connect Ø50 mm suction hose to the inlet
of the suction path diverter and lay to the
connection of the central extraction system.
Cut the suction hose to the required length
and connect. If necessary, use screw sockets
(optional .
Connect Ø50 mm suction hoses to the
outlets of the suction path diverter and lay to
the dust collection point.
Cut suction hoses to the required length and
connect to the dust collection points.
If necessary, reduce Ø50 mm suction hose
to Ø42 mm.
Hang suction path diverter on mounting
bracket.
