Operation
Turning extraction unit On
Press the main isolation switch to the “On” position (Refer
to section 1 for switch location) by depressing the ‘I’ side of
the switch.
Setting the desired airflow
The extraction unit features manual flow control. This
enables the user to set the required airflow rate. Over time
as the filters begin to block the user should manually
increase the motor speed to ensure the correct flow is
maintained 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
Press the Up arrow button to increase airflow and press the
down arrow button to decrease airflow. The level of airflow
is indicated by the vertical row of six blue LEDs to the right
of the mains isolation switch. As the airflow increases, more
blue LEDs light up and the opposite for decreasing the
airflow.

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 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.

Maintenance
Filter Replacement
Refer to section 2 02 for PPE requirements.
During use, the system will alert the user when its filter
needs replacing. When the filter needs to be changed, the
LED to the right of the bell symbol will flash red.
To remove and replace the filter follow the procedure
detailed below.
1. Isolate the electrical supply to the extractor
2. Undo the four clips on the sides of the unit and
remove the lid using the two handles on the top of
the lid.
3. Using the two strap handles on the sides of the
filter, lift the filter out of the unit. Once removed it is
recommend that the used filters are bagged and
sealed.
4. Lower the new filter into position.
Replace the lid, and fasten the four clips.
VOC option
The unit also has an option for a VOC (Volatile Organic
Compound) alarm option installed, the extractor will
monitor and detect the level of VOC particles in the air. If
the VOC level rises above a pre-set level then the LED to the
right of the bell symbol will flash red. This requires the
replacement of the filter.
Note: The filter MUST be fitted when the extractor is in
use.

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 1for location) to be connected
to a known and tested DC power supply, in order to start the
extractor. The signal needs to be connected to a double
insulated DC power supply.
The operating voltage for this signal is 24VDC. Only this
voltage should be connected. Voltages connected outside of
this range may cause irreversible damage to the relay.
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 (See section 5for
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.
Filter Blocked / System Fail Signal
With this option the extraction 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 extraction system.
Connection specification
This signal is available via the Green and White cores of the
signal cable. The 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.
The signal needs to be connected to a double insulated DC
power supply.
•Maximum input voltage: 24V AC
•Maximum current load: 3A @ AC
OR
•Maximum input voltage: 24V DC
•Maximum input load: 3A @ DC
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”

Replacement Parts
Consumable Spares
The extraction system contains a combined filter. These
should be replaced when instructed to do so by the 3D
PrintPro4 system (see section 6for replacing the filters)
