SAFETY INSTRUCTIONS
Symbols used
Danger Refers to an immediately impending danger. If the danger is not
avoided, it could result in death or severe (crippling) injury. Please
consult the manual where this symbol is displayed.
Warning Refers to a possibly dangerous situation. If it is not avoided, it could
result in death or severe injury. Please consult the manual where this
symbol is displayed.
Caution Refers to a possibly harmful situation. If it is not avoided, damage
could be caused to the product or to something in its environment.
Important Refers to handling tips and other particularly useful information.
This does not signify a dangerous or harmful situation.
Electrical safety
The AD range of extraction units are designed to meet the safety requirements of the
Low Voltage Directive 2006/95/EC (previously numbered 73/23/EEC) and UL61010-
1.
Warning During works with the pump/motor housing open, live, 230/115 volt
components are accessible. Make sure that rules and regulations
for work on live components are always observed.
Important To reduce the risk of fire, electric shock or injury:
1. Always isolate the system from the mains power supply before
removing the pump/motor panel.
2. Use only as described in the manual.
3. Connect to a properly grounded outlet.
Dangers to eyes, breathing and skin
Once used, the filters in the AD range of extraction units contain a mixture of
particulates, some of which may be sub micron size. When the used filters are
moved it may agitate some of this particulate, which could get into the breathing zone
and eyes of the operative. Additionally, depending on the materials being lasered, the
particulate may be an irritant to the skin.
Caution: When changing used filters always wear mask, safety glasses and gloves.
Please note the media in the gas filter fitted in this unit is capable of adsorbing a wide
range of organic compounds. However, it is the responsibility of the user to ensure it
is suitable for the particular application it is being used on.
This unit should not be used on processes with sparks of flammable materials or with explosive
dusts and gases, without implementation of additional precautions.

INSTALLATION
Introduction
When a component is laser marked an amount of the surface of the substance is
thermally decomposed, “burnt off”. This thermal decomposition comprises a mixture
of particulate and gaseous compounds. The heat energy causes the gases and
surrounding air to quickly expand moving away from the surface at high velocity
entraining any particulate with the gases. This is the fume.
There are two main reasons for capturing the fume:
1 Operational –if ignored the fume can settle on the laser optics causing
damage to the lens and impairing the quality of the marking.
2 Health and Safety –The particulate generated from most materials is sub
micron size which is a health hazard if inhaled and some materials give off
harmful gases which again operators need protecting from.
The AD range of units are suitable for extracting the fume from laser marking
applications, capturing it in the multistage filter system and returning the
associated clean air back into the workplace.
Fume Capture Methods
The fume is normally captured by one of three methods: a flexible arm and nozzle
close to the marking point, an enclosure around the marking area, or from the cabinet
the laser is housed in.
Arm and nozzle extraction
Fig. 1
For most applications, the product to be marked on a
conveyor will move past the stationary laser. The nozzle
should be positioned as close as possible to the marking
area on the side of the laser the product is moving towards.
(See fig. 1)
Hose Kit (see fig. 2)
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 end of the flexible
hose. Cut the flexible hose to suit the distance back to the extractor connection,
keeping it as short as practicable, then refit the connector and push onto the
extractor inlet.

6 Version 1 Oct 2009
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.
Fig. 2 Fig. 3
Enclosures
Extraction can be attached to an enclosure around the marking zone provided
the extraction point is situated within 50 -75mm of the marking point.
(See fig. 3)
Cabinets
(See fig. 4) Cabinets normally have a 75 or 100mm spigot for fume extraction.
For best performance use the same diameter hose as the spigot and reduce
at extractor if necessary. Keep the hose run as short as possible.
Extraction units should be sited in a well ventilated room.

Extractor Installation Procedure
Caution
If this equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
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 unit
from its packaging. The unit should be installed in a well ventilated room.
Caution
Due to the weight involved the extractor unit should only be lifted using suitable lifting
equipment and with regard to appropriate safety precautions. (See Appendix for
product weight details).
2. Ensure that a 0.5m space is available around any louvered areas of the unit to
ensure adequate air flow. Lock the two braked castors, if fitted.
Caution
Do not block or cover the cooling vents on the unit, as this severely restricts airflow
and may cause damage to the unit. (This may be located on the base of the unit).
Caution
Under no circumstances should the exhaust outlet/s be covered as this will restrict
the airflow and cause overheating.
3. Check filters are located in their correct position and carefully replace lid/close
door.
4. Connect the extraction ducting between the extractor inlet and the fume capture
device as detailed previously.
Optional Feature Considerations
5. If fitted, the following features need to be considered when installing the unit:

9 Version 1 Oct 2009
Important
If the AD unit has an exhaust air outlet spigot fitted, the exhausted air can be routed
outside of the building if required. It is important to keep any ducting used to do so to
a minimum, in order to reduce back pressure within the system.
Filter blocked/System failure signal
With this option the extraction unit will have been fitted with a pressure transducer to
monitor the condition of the filters and to indicate the extractor is running. In addition
to controlling the LED’s on the front of the unit, this signal is available via the green
and white cores of the control cable that exits the cabinet next to the power cable.
The signal is a “volt free” contact, i.e. a closed circuit will exist between the green and
white wires when the filter condition is good and the unit is running. This will change
to an open circuit on filter blockage or system failure. This feature should only be
used on control voltage circuits. The signal can be connected to the laser or
alternatively to operate a beacon, siren or warning device. Open circuit condition of
this circuit will not directly stop the extractor motor.
Remote stop/start
If this facility is installed it enables the extractor unit to be turned on and off by a
signal from the laser. The red and black cores of the control cable need to be
connected to a 5 –24v dc supply, which when applied will start the unit and when
switched off will stop the unit. However the mains power switch must be in the “on”
position for the signal to be effective. (Unless 0V stop/start option was specified when
ordered, for this connect the Red & Black cores together to start the extractor.)
Fig 6
Remote Stop/ Start Over-Ride
If fitted, remote operation can be overridden by using the override switch, which is
mounted inside the unit (see fig. 7).
Fig 7

10 Version 1 Oct 2009
Compressor
If the optional compressor is fitted, connect the compressed air line between the
laser and the extractor. Ensure that any water trap/ filter unit in use is situated
nearest to the laser (and not the extractor). The arrows (indicating air flow) on the
side of the water trap/filter should be pointing in the direction of the airflow (i.e. air
into the laser Unit).
Electrical supply connection
6. Check the integrity of the electrical power cable. Connect the power cable to an
isolated electrical supply. The mains socket outlet should be installed near the
equipment and be easily accessible. The cable run to the machine should be
arranged so as not to create a trip hazard.
Caution:
Check that the mains input at the isolated supply is the same as the voltage Supply
detail on the Serial Number label (115 - 230v 50/60Hz) before plugging the extractor
unit in.
General Safety Requirements
The mains socket outlet should be installed near the equipment and be easily
accessible.
Caution
Do not block or cover the cooling vents on the unit, as this severely restricts airflow
and may cause damage to the unit. (This may be located on the base of the unit).
Caution
This unit is over 18Kgs in weight and should only be lifted with suitable lifting
equipment.
Caution
If this equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
