4 Fitting the Fume Extractor hood

The Fume Extractor arm is already fitted. The hood

must be fitted according to 

Figure 2

. Adjust the links

so that the hood easily can be positioned.

X: Cable with loop.

5 Wiring diagram

See 

Figure 3

.

• M1: Fan motor, 0.75 kW.
• A1: Circuit card.
• T1: Transformer, 24 V secondary.
• K1: Relay, fan.
• F1: Overload protector relay.
• E1: Spotlight, 20 W, 24 V.
• H1: Alarm signal, 2.9 kHz.
• H2: Alarm signal, 2.9 kHz.

6 Initial operation

See 

Figure 4

.

1 Ensure the FilterCart W3 has not been damaged

during transport.

2 Check that the mains voltage is the same as on the

sign plate.

3 Connect the connection cable with plug to the

mains. The light emission diodes at B indicate

fixed light and an alarm signal sounds for a short

time. The light diode at C indicates blinking green

light (stand by).

4 Start the FilterCart W3 with the switch A or as an

alternative with the switch on the hood of the ex-

tractor arm.
The light emission at C indicates fixed green light:

The fan operates.

6.1 Overload protector

See 

Figure 4

. The FilterCart W3 is equipped with an

overload protector which means that the power will

disconnect automatically if the fan motor is over-

loaded.
• C: Red light emission light indicates: disconnected

power and released overload protector.

• D: Button for re-setting the overload protector.

 is only intended for in-

door use and is designed for extraction and filtration

of welding fumes, class W3. The hood of the extrac-

tion arm is to be positioned as close to the pollution

source as possible, see 

Figure 5

, item A. The hood is

provided with an efficient spotlight. The F

is to be moved from behind according to item B and

with the wheels unlocked. The extraction arm is to be

positioned with the wheels locked according to item C.

8 The control board indications

See 

Figure 6

.

1 When the mains plug is connected the light emis-

sion diodes indicate fixed light and an alarm signal

sounds a short time.

2 The light emission diode indicates blinking green

light: The FilterCart W3 has been connected to the

mains (stand by).

3 As the FilterCart W3 has been started the light

emission diode indicates fixed green light. The fan

is in operation.

4 The FilterCart W3 is ready for use and after a

while, the light emission diode indicates fixed

green light. After use for a certain time, the air-

flow will be reduced through the extraction arm

and the pressure drop will increase, which will res-

ult in having to change the filter cartridge.

5 The light emission diodes indicate fixed light: The

pressure drop has increased. Pre-warning for

changing the filter cartridge.

6 The light emission diodes indicate fixed light

and after about 30s an intermittent alarm signal

starts. Change the filter cartridge. If you want to

finish the work in progress before the filter cart-

ridge is changed, the alarm signal can be stopped

by pushing once on the start button. The alarm

signal activates after about 10 minutes. Push-

ing 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.

7 The light emission 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.

8 The light emission diode indicates fixed red light

and an intermittent alarm signal starts. The over-

load protector has been released. Examine the

reason and reset the overload protector by push-

ing the “Motor Protector Reset”- button.

9 Changing the filter cartridge

See 

Figure 7

. The filter cartridge is disposable and is

to be thrown away after use. The life span of the filter

cartridge varies greatly depending on how the Filter-

Cart W3 is used and how much and what type of pol-

lutants are collected.
Regularly check the light-emitting diodes on the pres-

sure drop symbol on the control board to know when

to change the filter cartridge, see 

Chapter 8 The con-

trol board indications

. Always check that the hoses for

the extraction arm and the fan inlet are undamaged

before it is decided to replace the filter cartridge.
