SECTION 1
DESCRIPTION OF THE CABINET
The Ductaire pro range of filtration fume cabinets are designed to provide operator
and environmental protection. The cabinet provides an inflow of air >0.5m/sec
through the working aperture to provide operator protection and when installed and
operated correctly are compliant to BS14175.
The Ductaire Pro fume cabinet working chamber is manufactured from fully welded
industrial quality copolymer polypropylene, complete with an integral spillage
containment area. The fully adjustable sliding vertical sash allows excellent access
to the large work area and fully isolated lighting ensures the area is well lit and easy
to work in. The cabinets are able to be specified with optional items such as power
sockets and water/gas services.
They can be supplied on a supply only basis or complete with full installation and/or
validation to BS7258 Part 4.
The system employed for airflow control is the Variable air volume (VAV) principle.
This maintains a constant containment velocity into the cabinet across the sash
aperture irrespective of the sash operating position.
The cabinet is able to be supplied with a variable speed fan controller for single fan
per unit situations or when connected into an existing communal duct system, a
variable duct damper is employed.

SECTION 2
INSTALLATION
The cabinet installation should only be carried out by suitably qualified persons.
•The cabinet should be sited in a draught free position and in accordance with
guidelines laid out in BS14175.
•The cabinet should be connected to a suitable fan/duct system with electrical
connections made to fan speed controller/duct damper as appropriate.
•Connect the cabinet to a 13A outlet socket.
•Optional Aux power sockets are provided with separate power plugs.
•Optional services (water/gas etc.) are supplied with connections located inside
the removable side panel. Remote valves are located on the same side as the
respective services where fitted and are clearly marked.
•As standard, the system relies on Variable air volume. A 0-10v terminal is
provided for connection to a VAV fan inverter drive or servo driven variable duct
damper valve. Electrical connections are located under the access cover behind
the front cover.
TESTING / COMMISSIONING
A test certificate will be supplied for conformity to CE marking, and electrical test.
The airflow should be checked using a vane anemometer and the results recorded.
THE CABINET MUST BE TESTED EVERY 14 MONTHS TO COMPLY WITH
C.O.S.H.H REGULATIONS.

SECTION 3
GENERAL OPERATION
The main on/off switch is located on the right-hand side near the top of the cabinet.
When first turned on the LCD control panel will be displayed providing operator
information relating to cabinet use.
CONTROL SYSTEM
The cabinet is controlled and monitored by a microprocessor with an LCD touch
screen. The touch screen provides the operator with general information about the
cabinet and displays the current face velocity and status. Control of light level, fan
on/off and other operating settings are all accessed via a menu system. To ensure
containment is always maintained and for increased energy efficiency, a constant
velocity, variable air volume (VAV) system is employed. This varies the volume of air
passing through the cabinet to maintain a constant face velocity regardless of the
sash position. The control system is factory set to maintain the following parameters:
Normal velocity: 0.55m/sec. (Velocity measured at the aperture)
Low velocity: 0.35m/sec.
Low airflow alarm: 0.30m/sec.
These settings can be changed by a Monmouth engineer. Please contact Monmouth
Scientific for further advice.
START-UP
When first turned on the screen below is displayed providing system status.
Additional cabinet information can be displayed by pressing the key.

7
FACE VELOCITY
The microprocessor controls the fan speed to maintain a constant face velocity
across the sash irrespective of its position. The value will fluctuate slightly during
normal operation, this is normal and is an indication that the fan is operating normally
and is under control. By default, the units displayed are set to M/Sec. If preferred the
units displayed can be changed to ft/min. in the Supervisor Settings (see page 11).

SETTINGS
Pressing the key on the main screen enters the Set-Up menu access screen.
The supervisor access code is supplied with the cabinet and allows access to
change operating preferences.
The engineer access code is reserved for service personnel to carry out
maintenance procedures.
The key returns to the normal display screen.

9
SUPERVISOR SETTINGS
When the correct Supervisor code is entered the screen below is displayed allowing
for various options to be configured.
Face Velocity Display - Select preferred velocity units.
Audible Alarm - Turns the audible low airflow alarm on/off.
Keypad Sounds - Turns the audible key beeps on/off.
Set Time - Displays a time / date setup screen, use the +/- keys to set the correct
date and time.
Pressing the key returns to the previous screen.

10
INFORMATION SCREEN
Pressing the key on the main screen will display the information screen below.
Service information is reset by a Monmouth engineer during a service visit. When a
service becomes due a warning screen will be displayed momentarily on start-up
during the preceding month.

SECTION 5
MAINTENANCE
The cabinet should be isolated from the electricity supply before carrying out
any maintenance procedures.
CLEANING
Proprietary glass cleaner can be used on the sash glazing.
All other surfaces should be cleaned with warm soapy water, and rinsed with fresh
water to remove residues using a soft cloth or sponge.
FUSES
The main fuses are located in the mains inlet socket on the top of the cabinet.
Always replace fuses with the correct type and rating.
LIGHTING
The high efficiency, low voltage LED light tubes are fitted to the inside of the front
cover. They should provide many years of service without requiring replacement.
Spare tubes are available from Monmouth Scientific.
For parts or service information please contact Monmouth Scientific.
ENIGINEER MENU
Pressing the key on the main screen enters the Setup menu access screen.

12
Enter the engineer access code to enter the Engineer Settings menu.
The Calibration key navigates to a further screen where all calibration options are
accessed.

13
AIRFLOW DISPLAY
This is a two stage procedure to calibrate the airflow display to the actual airflow. A
calibrated, rotating vane anemometer should be used. Follow the on screen
instructions.
The back key returns to the calibration menu without changing any settings.

14
AIRFLOW ALARM SETPOINT
The alarm point should normally be set to 0.35m/sec but may be changed if required.
The alarm point should not be set too close to the target airflow to avoid unwanted
alarms. The back key stores the set point and returns to the calibration menu.
MAIN AIRFLOW TARGET
Main Airflow Target is the face velocity the cabinet is trying to maintain. This should
normally be set to 0.50m/sec. but may be changed if required. The back key stores
the set point and returns to the calibration menu.
LOW FAN SPEED TARGET

15
Low Fan Speed Target airflow is the face velocity the cabinet is trying to maintain
while in low fan speed mode. This should normally be set to 0.35m/sec. but may be
changed if required. The back key stores the set point and returns to the calibration
menu.
SCREEN CALIBRATION
This should only be used if the touch screen requires calibration. This is usually
indicated by touch sensitive areas of the screen not lining up with the buttons. Follow
the on-screen instructions to carry out screen calibration.

16
LOG SERVICE VISIT
The date of last service and service due date (displayed on the information screen)
are updated using this screen. Selecting the service interval and pressing the Yes
key stores this information and returns to the service settings menu. The back key
returns to the calibration menu without updating the information.
