Important principles - read before installation and use
The unit consists of four modules which are connected
together with tension bands:
Upper part (bilde til venstre under)
The top module houses the fan and shaker motor, as
well as the discharge nozzle. The fan is activated man-
ually (pos. “MAN” on the electrical cabinet) or by oper-
ating ap valves and dampers with a microswitch (pos.
“Remote” on the electrical cabinet). After use, the shak-
ing motor is activated automatically and the dust falls
from the lter and into the waste bag. Immediately after
the discharge nozzle (ø125 mm) you should increase
the dimension to Ø200/250 mm and install a sound trap.

4
Second top part (picture in the middle above)
Here is the suspension ring for lter and lter. The top
two modules cannot be rotated relative to each other.
Inlet module (picture on the right above)
This is rotatable, and the inlet can be rotated so that
the inlet pipe is placed appropriately. This module also
houses the adjustable and capacitive sensor (see image
below). This sensor is placed and adjusted (adjustment
screw on top) if the sensitivity is too great.
Bottom module
Here are the waste bag and trolley (on the left below).
Check that the door is properly closed, please tighten
the locks (on the right below). False air can contribute to
a pressure di󰀨erence and that the bag is pushed up in
front of the capacitive sensor (sensor so that an alarm
(steady red light) is triggered. practice and environmen-
tal toxins fall into the waste bag in the lower part. The
unit is controlled by electrical panel ZE-WE-5, 5. The
panel in a convenient place near the unit.

5
We recommend the use of high-vacuum pipes and
damper/ap valves with microswitches.
We recommend using high vacuum tubes and parts to
avoid leaks. The unit is a high-pressure unit within the
eld of chip extraction, and spiro pipes are not accept-
able solutions. Long seam pipes with tension bands can
also lead to leaks. We also recommend that dampers
for machine connections, and ap valves for vacuuming,
be installed with microswitches for start and stop. In this
way, it is ensured that the damper is closed after use,
and that the unit is only in operation when required.
Machines are equipped with various connection pieces,
and adaptation to the processing machine must be ex-
pected.

6
Preferably place the damper at operating height, on
the same side as the processing machine’s on and o󰀨
switch.
Start and stop from valves and dampers
We recommend that you use a two-conductor cable,
lampet type cable (brown and blue, double insulated) 2
x 0.75 mm2. On the e-panel, the conductors are con-
nected to terminal blocks 9 and 13 (top right). Units af-
ter 2018, check the form for terminal block for start/stop
from dampers and ap valves (7 and 11).In the event of
a short circuit, the unit must start.
6 Installation and start
The WE-5,5 / D chip extractor is designed for use in a
closed room. It should be placed stably on an even oor
surface. It is important to have access to air for air circu-
lation and cooling, and that the user has enough space
to change the lter and waste bag. Woodworking ma-
chines are connected with a high-vacuum pipe, damper
and exible hose to the machine’s outlet. Flexible hose
is connected to the pipe network with a sliding damper.
When the sliding damper is pulled out, a signal is giv-
en from the corresponding microswitch on the damper
to the control unit, and the unit starts. When you have
nished using the woodworking machine, the damper is
pushed back and the unit stops.
The electrical panel should be installed in an easily ac-
cessible and convenient place for the user and it must
be connected 3 x 230 or 3 x 400V, 50 Hz.

7
A silencer (900/1200 mm – Ø200/250) and a spiro for
the outdoors are recommended on the return (Ø200/250
mm recommended). Electrical work must be carried out
by certied personnel in accordance with current regu-
lations.
See also chapter 5.
Before starting, check the following:
- Correct supply voltage and grounding
- Correct connection of phases on the motor, correctly
set motor protection, correctly secured main course
- Check the physical direction of rotation of the fan. If the
impeller has the wrong direction of rotation, the suction
is poor.
- Check motor protection settings, are these set slightly
above the rated current on motors?
- Check that all microswitches are correctly connected
on the panel
- Correct attachment of the bag lter and the waste bag
- Doors closed and tightened (“false” air can cause the
bag to be sucked up and sound the alarm)
- KCapacitive sensor must be adjusted correctly. The ad-
justment screw for sensitivity is under the black cover
screw.
- Test the device by setting the black switch to the
“Local” position
- Filter cleaner takes approx. 20 seconds after stopping
- Put the black switch in “Remote” and test start and stop
from dampers/valves/micro switches
7 Use, application and alarms
Connection of the main switch, the unit in stand-by
Turn the red switch to the “ON” position
- The yellow lamp (-H1) lights up.
Start of fan/extraction - test run
Turn the black control switch to the “Local” position to
start the test. The fan starts, indicated by a lit white sig-
nal lamp. Then set the black switch to the “Remote” po-
sition.
Operation/remote control of the unit
For automatic operation of the unit, set the red switch
to “On” and the black switch to “Remote”. The unit must
now be started and stopped when sliding dampers and
ap valves are used. Micro switches must be connected.
Disconnection of Aggregate:
To stop the unit, set the red switch (-S2) to position
“OFF” and then
turn the switch (-S1) to the “OFF” position.
Full-bag alarm (steady red light):
When the waste bag is full, or the capacitive sensor de-
tects something in front (for example a waste bag), the
red lamp (- H3) “ALARM” lights up. The fan is stopped,
the bag must be emptied or the obstruction must be re-
moved, the alarm can be reset and the system starts
again.
For emptying the bag; Open the bottom door, pull out the
trolley with the waste bag to change the bag.
Clean any capacitive sensor.
Replace the waste bag with a new one, place the trolley
into the unit, lift the bag into place with the weight arms
of the trolley, close the door properly.
NB! Clean properly if there are chips around the door/
gasket. False air will cause the bag to be sucked up and
trigger the alarm again!
Under normal conditions, the shaking motor starts and
shakes the lter for approx. 20 seconds each time the
unit is stopped. The shaking removes ne dust from the
bag lter and gives a longer lter life.
Error - motor protection tripped (ashing red light)
In the event of a fault on the motor protection switch
(-Q1) or (-Q2), the lamp (-H3) “ALARM” ashes. The fan
then switches o󰀨 automatically. Check the switch and
electrical connections, then start the fan by pressing the
(-S3) “RESET” button.
Examples of incorrect use and incorrect operating
areas:
a. Dust and gases beyond temperatures -20°C to 40°C.
b. Extraction of explosive dust and gases
c. Extraction of aggressive, damp or sticky media
d. Extraction of gas, smoke or dust below 10 microns
e. Extraction from hot processes (metal grinding)
Possible consequences of incorrect use:
- Clogged lters
- Damage to bearings and axles
- Corrosion damage
- Imbalance on fan, impeller
- Vibrations and damage to the shaker motor
- Deformations and fatigue fractures
- Damage due to friction
- Sparks and ignition sources can cause ignition
8 Problem solving
Always switch o󰀨 the power before working on the unit,
motor, electrics, impeller etc.
Extraction disappears while the fan is running.
Clogging in the suction channel, at a branch etc. Must be
opened and cleaned
Fan stops
Check motor, impeller, supply, fuse. Contact an elec-
trician. Regarding fan motor must be checked by the
manufacturer/specialist. Check any alarms (full bag or
engine protection)
Vibrations
Check the impeller for dirt or damage. Check engine for
bearing noise.

8
Engine overheating
Check for damage to the engine. Check cause.
Bad suction - incorrect direction of rotation of fan
Check the direction of rotation of the impeller (both direc-
tions of rotation will create suction). Exchange phases in
case of wrong direction of rotation.
Check for tight lter, channel network and damper/suc-
tion to processing machine.
Bag lter and waste bag
Replace bag lter and pressure equalization lter ap-
prox. once per year or when it is dense.
Change the waste bag when the bag is full. This is re-
vealed by inspection and visual inspection, or when the
full-bag alarm gives a signal. The sensitivity of the full-
bag sensor is adjustable, see the top of the sensor, un-
der the plastic screw there is a small brass screw that
can be adjusted as needed.
Make sure that the waste bag is placed properly in the
holder and that the holder is placed against the packing
before the door to the waste bag is closed.
Use only waste bags made of thick-walled paper.
If the bag is sucked into the lter unit, this indicates that
air is leaking in at the bottom door, and that this must
either be cleaned or tightened for better sealing.
Red warning light is lit/ashing - see chapter
9 Maintenance
Daily inspections include visual observations and func-
tion observations. Errors must be reported to mainte-
nance personnel.
Weekly/monthly inspection includes replacement, in-
spection of bag and lter, as well as cleaning of the unit
inside.
Parts that are replaced if necessary:
Waste bags, 240 L, are exchanged for equivalent paper
waste bags, plastic bags must not be used. These will
be absorbed at low pressure di󰀨erences.
Parts that are inspected and recommended to be re-
placed annually:
Parts that are inspected and recommended to be re-
placed annually:

16 Simple system description of chip ex-
traction WE-5.5 (5.5 kW)
The WE units have been developed for chip and chip ex-
traction in ductwork rooms and smaller carpentry work-
shops with a focus on the following parameters:
• Point extraction, closed system
• Vacuuming of benches and oors
• Ease of use and suitable automation
• Area-e󰀩cient and easy installation
• Simple maintenance
Point extraction, closed system
The unit produces up to 1,800 m3/h in free-blowing
mode, and normally has the capacity for 1-2 machines
in simultaneous operation. This of course depends on
the design of the pipe network and the total pressure
drop in the system. By leading the exhaust air out of the
room, you also avoid the return of odours, gases and
micro-particles, i.e. a closed system.
Vacuuming of benches and oors
The maximum static pressure turnover in the aggre-
gates is approx. 8,000 Pa. This is su󰀩cient to provide a
satisfactory vacuuming e󰀨ect, and is an appropriate way
of removing dust. The dust is removed at the rst touch
and the stirring up of ne particles, as when sweeping, is
avoided. Hand tools can also be connected to the vacu-
um cleaner outlet.
Ease of use and suitable automation
The units are supplied with
• automatic lter cleaning to avoid a clogged lter and
reduced suction volumes. After each shutdown, the l-
ter is cleaned automatically.
• capacitive sensor for notication of full bag. When the
waste bag is full, the unit stops, the bag must be re-
placed and the signal must be acknowledged before
re-starting the system (standard). Sensitivity is adjust-
ed after the system has been put into use and the dust
is known.
• start and stop using micro switches on machine
connections (dampers) and vacuum cleaner outlets
(ap valves). Micro switches short-circuit a 24 V circuit
and start the unit (standard).
• other automation on request.
Area-e󰀩cient and easy installation
The unit is delivered complete, with a free-hanging auto-
matic cabinet, is around ø800 mm, and has a rotatable
inlet module. This contributes to exible placement in
relation to where the pipe is placed. Usual locations for
the unit are in the ducting room or material warehouse.
Easy maintenance
The unit is an all-in-one unit. The waste bag is changed
when the bag is full alarm. The lter is normally changed
once per year. Fan is directly driven. The system is in-
spected once per year. Regular inspection for noises,
changes in suction volume or mechanical breakage.
Itek o󰀨ers complete service agreements with inspection
and parts replacement.
17 Usage poster – hung up in the storage
room
The WE units are intended for chip and chip extraction in
slough rooms and smaller carpentry workshops:
• Point extraction, closed system
• Vacuuming of benches and oors
• Ease of use and suitable automation
• Area-e󰀩cient and easy installation
• Simple maintenance
• Automatic on/o󰀨 when using ap valves/dampers
• DO NOT USE for emery wheels, cautery pens or any
thing else that can create sparks.
Point extraction, closed system
The unit produces up to 1,800 m3/h in free-blowing
mode, and normally has the capacity for 1-2 machines
in simultaneous operation. This of course depends on
the design of the pipe network and the total pressure
drop in the system. By leading the exhaust air out of the
room, you also avoid the return of odours, gases and mi-
cro-particles. The lter is cleaned with a shaking motor
after use.
Settings on electrical control box
• Red main switch for power on and o󰀨
• Black switch “Local” for test and manual operation
• Black “Remote” switch for daily operation and
operation from ap valves and dampers
• Shaking motor cleans the lter after each use.
Vacuuming of benches and oors
• Open ap valves, connect associated hoses. The unit
starts automatically and runs until you disconnect the
vacuum cleaner hose from the ap valve.
Chip extraction from machines
• Flexible hoses mounted on sliding dampers are
connected to the outlet of the woodworking machine.
The chip extractor/aggregate is started by opening/
pulling out the sliding damper. The sliding damper is
opened before the processing machine (saw, planer,
etc.) is started, and closed after the processing ma-
chine has stopped. If chips build up in the hoses, shake
the hoses while the unit is running to remove chips.
Regular inspection
• Dust is removed from dampers, ap valves and
aggregate.
• Dust is removed from the waste bag’s chamber and
door. The door MUST be closed.
• In the event of an alarm, check the operating instruc-
tions
• The bag is changed if necessary. Use the right card-
board bag.

15
• Check that the bottom door is tight and free of dust,
otherwise the bag will be sucked into the lter and give
an alarm.
• Filters are changed at least once a year
• Steady red alarm light means that the bag is full, or that
the bag is being sucked up
• Flashing red light means that a motor protection has
tripped
Read operating instructions!
NB! Fan and other moving parts can cause personal in-
jury if they are touched during operation! Only autho-
rized personnel must open the top hatch on the unit.
