Disposal Of Filter Bags; Appliance Plug With Automatic Switch-On/Off Function For Electronic Tool / Dust Generator; Volume Flow Display; Operation - Mafell S 25 M Originalbetriebsanleitung

4.5 Disposal of filter bags

Pull the filter bag carefully and without sudden
movements out of the filter bracket. Dispose of it in an
impervious bag in compliance with the valid
regulations for the disposal of such wastes.
4.6 Appliance plug with automatic switch-on/off
function for electronic tool / dust generator
The dust extractor is equipped with a socket outlet 4
(fig. 1) and automatic switch on/off function for
electrical tools.
To ensure that the entire dust is still vacuumed after
switch off and while the electrical tool is coasting
down, the electronic system only switches off the
vacuum cleaner approx. 3-5 seconds after the
electrical tool is switched off.

4.7 Volume flow display

When used as an industrial vacuum cleaner:
The fixed value of the volume flow display 3 (fig. 1) is
set such that when the average air speed in the hose
system drops below 20 m/s, the control display 3
blinks as indication that the filter bag or the container
is full.
When used as a deduster:
The monitoring unit of the minimum volume flow must
be set to the diameter of the hose that is to be used
for extraction (see table in section 1,2).
The minimum volume flow is
monitored at the deduster by
measuring the vacuum in front of
the fan. The operator can easily
adapt the monitoring unit to the
respective dust generator without
the need of tools.

Operation

Danger
The dust extractor is not suitable
for extracting dusts that are
hazardous to health.

5.1 Switching on and off

Switch positions for IV operation (industrial
vacuum cleaner) (fig. 1)
0 = Off
I = On (manual operation)
The volume flow display is switched over to
a fixed value which causes the signal lamp
to blink if the air speed drops below 20 m/s.
A = Stand-by mode for automatic switch on/off
function (dust extractor is switched on and
off by the electrical tool).
Switch positions for DED operation (deduster) Fig.
1
RA = Device designs with the equipment "RA"
can be operated as described under "A",
but in this case the vibrator is put into
operation for approx. 7 seconds for
automatic filter cleaning when the volume
flow display lights up and automatically
switches off afterwards.
The dust extractor S 25 M / S 25 L is equipped with
an electronic suction force regulator.The turning knob
2 can be used to adapt the suction power to the
material to be vacuumed.
The socket outlet 4 is provided for the connection of
an electrical tool (A/RA mode).
Danger
The electrical tool must be
switched off when it is connected.
When the power plug is plugged in,
the socket outlet is always live,
irrespective of the switch position.
In switch position "0", the socket
outlet can be used as extension
cord (e.g. for lamp).
Connected load: Dust extractor and
connected device max. 16 A.
To avoid excessive start-up peaks, the dust extractor
is equipped with a starting current limit (soft start).
