Extension Cord; Manual Control; Suction Control; Automatic Mode - Renfert Vortex compact 3L Mode D'emploi

3.4.1 e
xtension cord
Only use an extension cord that at least complies
with or exceeds OEM specifications. Check that the
cord has the correct minimum cross section:
Cord length
< 16 A
up to 20 m 1.5 mm²
(AWG 14)
20 to 50 m 2.5 mm²
(AWG 12)

3.5 Manual control

• Switch extractor on and off on main switch (3, Fig. 2)

auto

3.6 Suction control

• Suction power is adjusted by turning the main
switch (3, Fig. 2).
Suction power adjustment allows you to accurately
adapt the suction power to different extraction chal-
lenges in both Manual and Auto mode.

3.7 Automatic mode

The electrical dust generator (electrical appliance)
turns the extractor on or off. Intended use includes
that electrical appliances connected to the extractor
must be certified for dusty environments.
Observe the maximum tolerable power
input of the electrical appliance to be con-
nected: See section „Technical Data".
Before setting the selector to „auto" check
that the connected electrical appliance is
turned off.
• Turn off extractor.
• Turn off electrical appliance.
• Connect suction hose to both electrical appliance
and extractor.
• Plug electrical appliance into power socket on the
extractor (Fig. 13).
• Switch the extractor to Automatic mode on the main
switch (3, Fig. 2), switch position „auto".
• Turn on electrical appliance.
• The extractor will start as you turn on the connected
electrical appliance.
When you turn off the electrical appliance,
the extractor will trail off for a couple of
seconds to ensure that any dust in the hose
is completely blown into the dust retainer.

3.8 Cleaning the fine filter „Free-
Filter-System"
When suction begins to be less powerful:
• Set selector to „I" (maximum power).
• Put hand over nozzle or hose outlet (Fig. 14).
• Press „Free-Filter-System" button three times
(Fig. 14).
This will generate an airflow which blows off dust
that may have settled on the slats of the Fine particle
filter.
In doing so, the dust from the inside surface will also
fall from the dustbag or cloth filter.

3.9 Extraction methods

Efficient cleaning can be reached by combining some
general guidelines with your own experience from
your specialist field of application.
Here is some general information.
3.9.1 t
o extract dry suBstances
When extracting dry materials it is essential to use a
dustbag or a cloth filter together with a disposal bag
at all times (see section „Accessories").
This will provide a simple and hygienic means of
disposing of the extracted material.
Extracting liquids will leave a wet fine particle filter
behind. A wet fine particle filter will readily clog up if
dry substances are extracted afterwards. Before you
start extracting dry substances you should therefore
wash and dry the fine particle filter or replace it with a
dry one.
3.9.2 t
o extract liquids
Always remove the dust bag/disposal bag before you
start extracting liquids.
We recommend using a separate fine particle filter.
Immediately interrupt the work in progress
and empty the dust retainer when you no-
tice that foam is beginning to form.
After extracting liquids take off the top of the extractor
housing and keep separate to allow the fine particle
filter to dry.

4. Cleaning / Servicing

Switch the device off and remove the plug
from the power supply before cleaning or
servicing.
The device must be checked at least once a year by
the manufacturer or a trained person.
The filter system must be examined for damage and
to ensure it is leak proof.

4.1 Check seals

Whilst changing the dustbag, the disposal bag or
the fine filter, always check the condition of the dust
retainer edge and seal in the extractor's top section.
A dirty or damaged dust retainer rim or seal
will reduce the suction power.
