EN
FilterCart W3 filters out pollutants such as fumes and dust, class W3. Moreover it filters out welding fumes con-
taining CMR (Carcinogenic Mutagenic Reprotoxic) substances, e.g. generated by welding high alloyed steels or
welding consumables with more than 5 % (Cr, Ni).
The FilterCart W3 is only intended for indoor use and is designed for extraction and filtration of welding fumes,
class W3. The hood is provided with an efficient spotlight.
NOTE!
The FilterCart W3 does not have any connections for the channelling of exhaust air.
3.1 Overload protector
See Image 4 . The FilterCart W3 is equipped with an overload protector which means that the power will discon-
nect automatically if the fan motor is overloaded.
• C: Red light indicates disconnected power and released overload protector.
• D: Button for re-setting the overload protector.
3.2 Control panel indications
See Image 6 .
A When the mains plug is connected the light emission diodes indicate fixed light and an alarm signal sounds
for a short time.
B The light emitting diode indicates a blinking green light: The FilterCart W3 has been connected to the mains
(stand by).
C As the FilterCart W3 has been started the light emission diode indicates fixed green light. The fan is in oper-
ation.
D The FilterCart W3 is ready for use and after a while, the light-emitting diode indicates fixed green light.
After use for a certain time, the airflow will be reduced through the extraction arm and the pressure drop
will increase, which will result in having to change the filter cartridge.
E The light emitting diodes indicate fixed light: The pressure drop has increased. Pre-warning for changing the
filter cartridge.
F The light-emitting diodes indicate fixed light and after about 30 s an intermittent alarm signal starts.
Change the filter cartridge. If you want to finish the work in progress before the filter cartridge is changed,
the alarm signal can be stopped by pushing once on the start button. The alarm signal activates after about
10 minutes. Pushing twice on the start button makes a fan stop. As an alternative, the fan can be stopped
with the switch on the Fume Extractor hood.
G The light emitting diode indicates blinking red light = alarm memory. The FilterCart W3 has been stopped
after the alarm start (according to above), for example at work shifts. The filter cartridge has to be changed.
H The light emitting diode indicates fixed red light and an intermittent alarm signal starts. The overload pro-
tector has been released. Examine the reason and reset the overload protector by pushing the "Motor Pro-
tector Reset"- button.
