1. INTRODUCTION
Dear Consumers!
Company ALFA IN a. s. thanks you for buying our filtration equipment and
believe that you will be satisfied with our machine.
FILTER UNI 2.2 is intended for the local exhausting of pollutants generated
during welding. The filter can be equipped with one or two suction arms.
Air pollutants generated during welding are fed to a three-part filter set, where
mechanical particles are trapped. At devices equipped with fourth filtration stage
with activated carbon are also trapped gaseous pollutants. Thereafter,
the cleaned air is discharged back to the work area by means of a fan.
FILTERS UNI 2.2 meet the requirements of the CE brand and are manufactured
in the EU.
We reserve the law of adjustments and changes in case of printing errors,
change of technical parameters, accessories etc. without previous notice.
These changes may not be reflected in the manuals for use in paper or electronic
form.

5. GETTING STARTED
ARM ASSEMBLY
Depending on the model, the FILTER UNI is equipped with one or two suction
arms.
Screw the suction arm tightly by means of the enclosed screws through the holes
in the flange to the holes in the top cover.
GETTING STARTED
1. Switch on the machine with the mains plug. The mains connection must
correspond to the technical parameters of the respective hood type in this
manual.
2. Turn the machine on by rotating the ON/OFF switch V1 to the position ON
and then long pressing the ON button (pos. V6) on the control panel, the
ON button lights up.
3. If the LED V2 – DIRTY FILTER on the control panel lights up, it is
necessary to clean or replace the filters.

according to the specifications shown on the V3 display.
5. Adjust the suction arm so that the suction nozzle will be placed from the
side 30 – 50 cm above the welding point.
6. After finishing the work, turn the machine off by means of the long pressing
the OFF button (pos. V5) – the OFF button lights up, then rotate the
ON/OFF switch V1 to the position OFF – the OFF button goes out.

MACHINE SPECIFIC FUNCTIONS
Hour meter
Stores the count of hours the machine has been ON, with a 10 minutes resolution
(the count displayed is in hours). The count of hours is saved automatically every
10 minutes, so if the machine loses electric power the maximum operating time
lost in the ON state is 10 minutes. When an alarm occurs the hour meter is saved
immediately, so in case of loss of power supply immediately after an alarm
nothing goes lost.
Alarms / warnings
Alarms and warnings are generated in the event of an anomaly only with the
machine ON. To restore them it is necessary to turn the machine off, enter the
service menu - reset alarms and enter the appropriate password. After the
restoration if anomaly conditions persist alarms / warnings will be generated
again when the machine is turned ON. Alarms not restored are re-activated in
case of disconnection and subsequent connection of the power supply. Below is
the list of alarms as they appear on the display V3:
 W01 – DIRTY FILTER: dirty filter warning (threshold defined by the DIRTY
parameter FILT. EDGE of the factory menu, which can be disabled, only
for the machines with analogic pressure switch or 600 h)
 W02 – EXHAUST FILTER: warning of exhausted filter (threshold defined
by the parameter EXHAUST F. EDGE of the factory menu or by the digital
pressure switch if enabled)
6. MAINTENANCE
FILTERS REPLACEMENT
The service life of the filters and the replacement intervals vary according to the
different applications of the extractor. If the filter is clogged, the LED V2 – DIRTY
FILTER on the control panel lights up.
Filters compartment door A, B, C must be unlocked. First pull the filter frame C
(bottom). The other two filters can then be removed more easily.
