Dangers to eyes, breathing and skin
Once used, the filters within the AD Nano system may
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 used, the particulate may
be an irritant to the skin.
This unit should not be used on processes with sparks of
flammable materials or with explosive dusts and gases,
without implementation of additional precautions.
Caution: When changing used filters always wear a mask,
safety shoes, goggles and gloves.
Carbon selection
Please note that the media within the filter fitted in the AD
Nano 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.

Fire Risk Warning
In the very rare event that a burning ember or spark is drawn
into the fume extraction unit, it may be possible that the
filters will ignite.
Whilst any resultant fire would typically be retained within
the fume extraction unit, the damage to the extractor would
be significant.
It is therefore essential to minimise this risk by undertaking
an appropriate 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.
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.

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.

Connection to Power Supply
Please follow the above specification when selecting the
power supply outlet for the AD Nano system, ensure the
power supply is suitable before connecting the AD Nano
system.
Check the Integrity of the electrical power cable, if the
supply cord is damaged the extraction unit should not be
connected to the mains. The supply cord should only be
replaced by a BOFA engineer as an electrical safety test may
be required after replacement.
The AD Nano MUST be connected to a properly
earthed outlet.
If your AD Nano system was ordered with any optional
extras please read section 4.02 before the
power connection is made as additional
connections may be required before power is connected
to the extractor.

Installation
Optional added features
The AD Nano can be configured to suit customer
specification. These optional extras would be discussed,
arranged and installed prior to delivery.
(If unsure what features your 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.
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.
Filter Signal
When the filters become blocked or the system develops a
fault 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”
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.

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 finish 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.
Filter Information
A log of filter changes should be maintained by the user.
The filters require attention when the display shows the
configuration shown on the next page 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.
