ignite.
Whilst any resultant fire would typically be retained within the
fume extraction unit, the damage to the extractor could be
significant.
It is therefore essential to minimise the possibility of this occurring
by undertaking an appropriate Risk assessment to determine:-
a). Whether additional fire protection equipment should be
installed.
b). Appropriate maintenance procedures to prevent the risk of
build-up of debris which could potentially combust.
02

This unit should not be used on processes where sparks could
occur, with explosive dusts and gases, or with particulates which
can be pyrophoric (can spontaneously ignite), without
implementation of additional precautions
It is essential that nozzles or other extraction/ fume capture
devices and hoses/pipework are cleaned regularly to prevent the
build-up of potentially ignitable debris

Before Installation
Inner transit packaging removal & unit placement
Before installation, check the extraction unit for damage.
All packaging must be removed before the unit is connected
to the power supply.
Please read all instructions in this manual before using
this extractor.
1. Move the unit to the location where it is going to be
installed and remove the outer packaging. This unit
should be installed in a well-ventilated area.
2. Open the front door and remove the transit foam
from the centre of the unit.
Caution
Due to the weight of the extractor suitable lifting equipment
should be used and with regard to appropriate safety
precautions. (See Appendix for product weight details)
Ensure that 500 mm space is available around any vented
panels on the extractor to ensure adequate airflow.
3. With the unit in position lock the 2 front castors.
Caution
Do not block or cover the cooling vents on the unit,
as this severely restricts airflow and may cause
damage to the unit.
Caution
Under no circumstances should the exhaust
outlet/s be covered as this will restrict the airflow
and cause overheating.
4. Check the filters are located in their correct position
before closing the door and securing the door latches.

Installation
The iQ extraction unit has been designed to remove and
filter fume containing potentially hazardous particulate and
gases generated during manufacturing processes. Such
hazardous substances are captured within a multistage
filtration system after which the cleaned air is returned to
the workplace.
Fume Capture Methods
The fume is normally captured by 1 of 3 methods.
•Flexible arm/ Nozzle
•Enclosures
•Cabinets
General Guidelines for a successful installation
•Keep duct run length to a minimum
•Avoid sharp bends / turns in the ductwork
•Avoid multiple bends / turns in the ductwork
•Use a larger diameter duct where able
•Position the capture device as close as possible to
the marking point. (if used on high speed lines,
position the capture device slightly downstream)
Flexible Arm & Nozzle Extraction
The stay put arm should be mounted as close as possible to
the marking point using the horseshoe clips. Unscrew the
push fit connector from the other side of the flexible hose.
Cut the flexible hose to suit the distance back to the
extractor connection and push onto the extractor inlet.
Purge air should be kept to a minimum, where possible, to
prevent the fume being blown away from the nozzle.
High speed bottling lines may need bigger scoops or nozzles
both sides of the bottles because of the turbulence caused
by the speed of the bottles.
Moving products
For applications where the product to be marked is moving
past the stationary Process the capture nozzle should be
positioned as close as possible to the working area on the
side the product is moving towards.
Enclosures
The extraction hose and nozzle can be attached to the
enclosure surrounding the marking zone provided that the
extraction point is within 50-75mm of the marking point.
Cabinets
Cabinets normally have a 75mm 0r 100mm spigot for fume
extraction. For best performance use the same diameter
hose as the spigot and reduce at the extractor end if
necessary. Keep the hose run as short as possible.
Connection to extraction unit
All ductwork should be installed and connected to the
extraction unit before the iQ system is turned on.
Exhausting filtered air outside
If requested your iQ extraction unit will have been fitted
with an exhaust outlet spigot. This provides a connection
point for exhaust pipework to be fitted. It is important to
keep any ducting to a minimum, in order to reduce back
pressure within the system.

Optional added features
The extractor can be configured to suit customer
specification. These optional extras would be discussed,
arranged and installed prior to delivery.
(If unsure what features your iQ system is equipped with
please contact the seller with the unit serial number,
(Refer to section 2for location) who will be able to advise
what specification has been supplied.
Remote Stop/Start feature
Enables the extraction unit to be remotely turned On / Off
via an external signal.
This feature can be configured in 3 ways
•DC Voltage input –Range 12-24VDC
•Volt free input –Open / Closed contacts
•Override –Stop / Start feature switched off
Note: Care must be taken to ensure that the system is
correctly wired in order for the extraction unit to function
correctly.
DC Voltage input
This configuration requires the Black & Red cores of the
signal cable (Refer to section 1 for location) to be connected
to a known and tested DC power supply, in order to start the
extractor.
The operating voltage for this signal is between 12 &
24VDC. Only voltages within this range should be
connected. Voltages connected outside of this range may
cause irreversible damage to the internal control PCB.
Red cable = V+
Black cable = V-
When the extractor is provided with the correct DC voltage
the motor will start and maintain the set flow rate (Refer to
section 5for how to set the flow) when the DC voltage is
removed the motor will slow down and come to a stop.
The extractor will need to be turned on and be out of
standby mode (See section 5 for turning the extractor on) in
order for this feature to operate.
Volt free input
This configuration requires the Black & Red cores of the
signal cable (see section 1 for location) to be connected
together, in order to start the extractor. The cables should
be connected to a clean switching device.
When the 2 cables are connected together the motor will
start and maintain the set flow rate (see section 5for how to
set the flow)
when the 2 cables are disconnected the motor will slow
down and come to a stop.
The extractor will need to be turned on and be out of
standby mode (See section 5 for turning the extractor on) in
order for this feature to operate.
Override
Enables the extractor to operate fully with or without either
DC voltage input or the Volt free input.
The override feature can be toggled On / Off by a switch
mounted on the internal motor access panel (see below for
switch location)
Switch in “On” position
In this position the extractor will require a start signal (either
Voltage input or Volt free, depending on the requested
specification) to enable the motor within the extraction unit.
Switch in “Off” position
In this position the extractor motor will run without the
requirement for an external start signal. This feature is
useful for engineers carrying out works/ tests on the
extractor without the need for the laser / auxiliary signal
being present.
The power supply unit which is used to provide the 12-
24VDC start stop voltage signal must be protected by
double insulation from mains voltage.

Filter Blocked / System Fail Signal
With this option the iQ system will output a signal to alert
the user when the extractor has failed or when the filters are
blocked.
This feature will not directly stop the extractor from running
correctly, but if fitted this feature should be terminated
correctly before power is applied to the iQ system.
Connection specification
This signal is available via the Green and White cores of the
signal cable. The iQ system will provide a volt free Open /
Closed signal that can be connected to an external interface,
beacon or warning device following the specification below.
•Maximum input voltage: 24V AC
•Maximum current load: 3A @ AC
OR
•Maximum input voltage: 24V DC
•Maximum input load: 3A @ DC
Filter Signal Configurations
There are 3 ways this signal can be configured, as detailed
below.
•Combined signal (standard specification)
•Separated signal
•Reversed separated signal
Combined signal
With this configuration the Filter blocked & System fail
signals will be linked together to give a combined single
output.
When the filters become blocked or the iQ system develops
a fault (Refer to section 8 for Troubleshooting & Error
codes) the connection between the Green & White cables
will become “Open”
When the extraction system is running normally the
connection between the Green & White cables will become
“Closed”
Separated Signal
With this configuration the Filter blocked & System fail
signals will be separated to give 2 individual signals.
When the filters become blocked the connection between
the Green & White cables will become “Open”
If the iQ system develops a fault (Refer to section 8 for
Troubleshooting & Error codes) the connection between the
Blue & Yellow cables will become “Open”
When the extraction system is running normally the
connection between the (Green / White) & (Blue / Yellow)
cables will become “Closed”
Reversed Separated Signal
With this configuration the cable function will remain the
same as the Separated signal option, but the signal given
will be reversed.
For blocked filters the connection between the cable cores
will be “Closed”
For iQ system faults the connection between the cable cores
will be “Closed”
For system OK the connection between the cable cores will
be “Open”

Operation
#
Setting the desired Motor Speed
The iQ system features automatic flow control. This enables
the user to set the required airflow rate, then over time as
the filters begin to block the motor will automatically begin
to increase in speed to compensate for any loss in
performance caused by the added restriction of the partially
blocked filters.
The extractor and all pipe work must be fully
installed and connected before the airflow is set.
To set the airflow
(The motor speed can be set between 1-100%)
1. Press and hold the “Enter” (middle) button (Refer
to section 1 for button location) for 3 seconds, or
until all 3 button lights flash green.
2. Release the Enter button, the iQ system is now in
set mode. Press either the Up or Down button to
adjust the airflow accordingly.
Real time airflow is displayed on the LCD screen,
Refer to section 1 for Display information)
3. Once you have your desired airflow, leave the
controls, after around 10seconds the flashing
buttons will illuminate constantly to confirm the
airflow is stored.
The set airflow will now be maintained throughout the life
of the filters. When the extraction unit can no longer
maintain the set airflow an alarm will be given and the
display will indicate which filter should be changed.
For multi-arm systems, the iQ unit will automatically
increase/decrease the motor speed as extraction points are
installed or removed to maintain the same flow through
each extraction point.

Maintenance
#
Maintenance UK
It is a legal requirement, under regulation 9 of the COSHH
regulations that all local exhaust ventilation systems are
thoroughly examined and tested at least once every 14
months (typically carried out annually). The approved code
of practice recommends that a visual check should be
carried out at least once a week.
COSHH requires the annual inspection and testing to be
carried out by a competent person and specifies that
documentation results are recorded in a log.
Contact the seller for more information about inspection
and certification.
Maintenance General
User maintenance is limited to cleaning the unit and filter
replacement, only the manufacturers trained maintenance
technicians are authorised to carry out component testing
and replacement. Unauthorised work or the use of
unauthorised replacement filters may result in a potentially
dangerous situation and/or damage to the extractor unit
and will invalidate the manufacturer’s warranty.
Cleaning the unit
The stainless steel units should be cleaned with a
proprietary stainless steel cleaner, in accordance with the
manufacturer’s user instructions
The powder coat finished units can be cleaned with a damp
cloth and non-aggressive detergent, do not use an abrasive
cleaning product as this will damage the finish.
The cooling inlets and outlets should be cleaned once a year
to prevent build-up of dust and overheating of the unit.
Replacing Filters
The iQ system constantly monitors the condition of the
individual filters. As the filters block the LCD display will
show the relevant filter symbol filling up. (see section 1 for
LCD details) Each filter symbol fills up in 5% increments,
when the filter icon is filled that particular filter will need
replacing.
Pre Filter blocking Combined Filter Blocking
A log of the changes should be maintained by the user.
The filters require attention when the display shows the
filter blocked icon/ filter output signal (if fitted) or when the
extractor no longer removes fume efficiently.
It is recommended that a spare set of filters are kept on site
to avoid prolonged unit unavailability. Part numbers for
replacement filters can be found on the filters fitted in your
system.
To prevent overheating, units should not be run with a
blocked filter condition, or with dust obstruction of Inlets /
Outlets.
75% filter blocked indication
When the filters become 75% blocked the buttons on the
front of the extraction unit will turn from Green to Amber
and if fitted the iQ system will output a signal to indicate
this. At this time it is recommended spare filters are
available as a change may be needed shortly.

iQ Display System
#
iQ Display Features
The iQ display has the ability to display all the faults
associated with your extraction unit. The image below
shows an example of some of the fault icons that may
appear in the alarm window of the LCD display.
Visual Alarms on the iQ system
The iQ system can visually display a wide range of alarms on
its LCD panel. The visual displays, meanings and solutions
are detailed below. All alarms will trigger the system alarm
interface output signal and the inbuilt audible buzzer, if
fitted/ activated.
Over Temperature Alarm
If the iQ system detects an internal temperature greater
than 60oC then it will automatically shut down the extractor
to prevent damage to components within the extractor.
Once the internal temperature has dropped by 50C the
extraction unit will be able to restart.
To restart the extractor after an over temperature alarm the
unit needs to be placed in Standby mode then powered on
again.

iQ Display System
#
Heat Detection Shut off
The iQ system has an internally mounted thermal trip. That
detects the temperature in the filter compartment. If the
temperature rises above 55oC then the extraction unit will
automatically shut down the motor and display the symbol
below.
If this symbol is displayed the unit should be totally isolated
from the mains supply and the unit should be fully inspected
for evidence of the temperature rise. (Including inside the
Pre filter)
Once the unit is safe to turn back on and the internal
temperature has dropped below 50oC the thermal trip can
be reset. To do this follow the procedure below.
1. Isolate the supply from the extractor
2. Open the front door & remove the Combined Filter
3. Locate the circular cut out in the shelf, at the front
of the unit.
4. Inside the cut out there is a small red button that
can now be pressed back in.
5. Re-fit the Combined Filter, close the front door and
re connect the mains supply.
Gas Filter monitoring (VOC Sensing)
If the VOC (Volatile Organic Compound) sensing option has
been fitted to your iQ system then this will be constantly
monitoring the exhaust gas of the extraction unit.
If the VOC level in the exhaust exceeds the PPM (Parts per
million) level pre-set at BOFA then the Gas alarm will be
triggered and display the Gas icon as shown below.
Removing the Gas alarm warning
The VOC option is a perfect way to monitor how the carbon
section of the combined filter is performing. Once the
carbon within the filter is saturated the VOC sensor will
alarm. At this point the extractor should be isolated from
the mains and a new combined filter fitted. Once a new
filter is installed the alarm will clear.
Door Open Alarm (Special Request)
If a door open alarm was requested at the ordering stage the
extractor will have been fitted with a micro switch to detect
if the front door has been closed correctly. If the door has
not been closed correctly the ‘door open’ symbol will be
displayed.
Run Safe Feature
To ensure personnel protection and avoid damage to the
unit the iQ system will automatically shut down 5 seconds
after no combined filter is detected. If no combined filter is
fitted the motor will stop and the display will appear as
below.
To resolve this, isolate the extractor, fit the combined filter
(see section 6.02) and turn the extractor on.
