PRINCIPLES OF OPERATION
Air is drawn into the cupboard at the working aperture Abelow the hinged clear acrylic
front window, at a velocity high enough to ensure entrainment of any fumes/odours given
off by the processes carried out within the cupboard.
The fumes from within the cupboard are drawn either upwards as in the case of lighter
than air fumes B to the extract slot D, or drawn across the work surface to the secondary
extract slot Ecreated by the back baffle, as in the case of heavier than air
fumes/particulates* C.
The combination of extract slots Dand Eensure that all fumes/particulates* are carried
by the moving body of air to the pre-filter Fand main filter G to be absorbed before being
expelled by the exhaust fan Has clean air J
The fan H, which is mounted above the main filter exerts a negative pressure on the
internal space within the cupboard. This in turn pulls external air into the cabinet through
the working aperture Aand keeps a constant circulation of pre-filtered clean air passing
through the cupboard whilst ensuring that fumes/particulates* are trapped and adsorbed
by the main filter.
*dependent on main filter type fitted.

OPERATING INSTRUCTIONS
(ENSURE THE UNIT IS PLUGGED IN TO THE MAINS ELECTRICAL SUPPLY)
1. Before switching on the unit, check that the main filter is fitted (the filter
identification label will be visible through the filter viewing window on the upper
fascia panel.
2. Switch on at the mains socket and at the green ON/OFF switch on the cupboard
and allow it to run for approximately 10 minutes prior to use.
3. Always use appropriate PPE (personal protection equipment) when using the
Airone FC750 Fume Cupboard.
4. Assess the potential hazard of the intended procedure before commencing work.
The hazard level can be reduced by:
Working with a reduced height of sash opening.
Using reduced quantities of substances involved.
Lowering reaction rates where acceptable.
5. When working in the cupboard, ensure that the hinged acrylic front window is in
the closed position, in order to achieve containment at 0.4M/sec and always keep
closed when the fume cupboard is not in use.
6. If using Bunsen burners, place them at least 20cm from the front sash, sides or
rear baffle.
7. For access to the inside of the fume cupboard for loading apparatus or cleaning,
the hinged lower front acrylic panel, can be fully open and will be held in position
by the two black detent hinges.
NOTE
The hinges will only hold the lower front panel in
the fully open position, when opening make sure
that they click into the fully open position.

OPERATING INSTRUCTIONS
(CONTINUED)
8. Try to place everything required for your process inside the fume cupboard prior
to starting any operation. This will reduce the amount of arm movements into and
out of the fume cupboard and hence reduce possibility of breakout (fume escape).
9. Position apparatus inside the fume cupboard so that disturbance to airflow at the
sash opening is minimised.
10. After use follow the correct procedure for disposal of any residues and leave the
fume cupboard in a safe state for further use by others.
11. Before switching off the cabinet after use, allow it to run for a further 5 to 10 minutes
to make sure all hazardous vapours or gasses have cleared, and check that any
bottle are capped or stoppered and no material has been left on the necks or
pooled around the bases.
Good housekeeping is essential to prolong carbon filter life.
FILTER SATURATION ALARM
This unit is fitted with a filter saturation alarm:–
In normal operation, the arrows will be lit with green LEDs. If these turn red and the
audible alarm sounds, it will indicate that the filter is potentially saturated or a
breakthrough has occurred.

MAINTAINANCE AND PERFORMANCE MONITORING (CONTINUED):
INSTRUCTIONS FOR FACE VELOCITY MEASUREMENTS
(Record results on record form - page 15 )
PROCEDURE:
Imagine the face of the fume cupboard divided into nine
cells.
Stand as far as practicable from the fume cupboard with the
sensing head in the plane of the sash and take airflow
readings at approximately the centres of each of the nine
cells.
Record for each cell the approximate average reading over a period of at least ten
seconds, applying any corrections from the air flow meter calibration chart.
Look at the table and repeat any reading which seems to be very different from the
general pattern. Record the average of this and the previous reading.
CALCULATION:
Minimum face velocity -
Record which of a,b,c,d,e,f,g,h,i, is the smallest, i.e.: the minimum face velocity.
VARIATION:
Check for variation as follows :
Add together the values a,b,c,d,e,f,g,h,i and divide by 9 to get the average.
Find the biggest and smallest of a,b,c,d,e,f,g,h,i.
The upper percentage variation is the biggest minus the average, divided by the
average and multiplied by 100.
The lower percentage variation is the average minus the smallest, divided by the average
and multiplied by 100. Each of these should be below 30%.

MAINTAINANCE AND PERFORMANCE MONITORING (CONTINUED):
INSTRUCTIONS FOR FILTER SATURATION TESTING.
Regular filter checks and monitoring (once a week is recommended) to test quality of the
air breathed in by operators and filtration efficiency. Filter challenge tests can be carried
out during routine Service and Maintenance procedures once every 6 months as
described in the Operational Safety Log Book.
The recommended procedure for testing the efficiency of the system requires a GASTEC
Volumetric Detector Pump and Gastec Chemical Detector Tubes. Test the quality of air
by sampling at eye and mouth level at regular intervals once a week with Gastec tubes
calibrated for the particular compound in concentrations below its respective OEL
(Occupational Exposure Limit) MEL (Maximum Exposure Limit) or OES (Occupational
Exposure Standard (or MAK in Germany and/or TLV in the USA).
Please refer to the Chemical Listing, Adsorption Index and Gastec Detection Guide
published in our Operational Safety Log-Book.
CLEANING
The materials used to construct the Airone FC750 Fume Cupboard have been selected
to give maximum durability and a long life. It is beneficial however to regularly clean and
decontaminate the internal and external surfaces.
It is recommended that the cabinet is switched on during any cleaning procedure and that
suitable protective clothing (face-mask, gloves and safety glasses) is worn.
All surfaces should be cleaned with a mild detergent solution then finished off with a damp
cloth and wiped dry.
If required, the rear/upper baffles can be removed for cleaning. It is recommended that
two people undertake this operation.
Remove the upper screws from the rear baffle, then undo and remove the thumbscrews
supporting the front of the upper baffle and allow in it fold down flat against the rear baffle.
Carefully remove the remaining bottom two screws holding the rear baffle whilst
supporting it.

TROUBLESHOOTING
1. What if I can smell the vapours or gases being used in the procedure?
Filters have a high efficiency but, because the nose is very sensitive, the residual
gases passing through the filter may sometimes be smelt, even though their level
is not hazardous. If the gases are causing distress, the operation should be
finished and the degree of filter saturation monitored.
2. What if I can smell the vapours or gases being used in the procedure,
but I have checked the filter performance and it is satisfactory ?
Check siting of the cabinet to ensure that nothing is being allowed to escape out
through the sash. Fume containment is easily impaired by draughts from windows,
doors or fan heaters and air vents.
3. What if there is a release that the filters of the Airone FC750 cannot contain?
If the initial chemical hazard analysis or risk assessment (under COSHH) has been
carried out correctly resulting in correct selection of appropriate types of carbon
filters followed by weekly air sampling and filter monitoring checks this is unlikely
to occur. In case it does happen, due to accidental release of gas or vapour or an
unexpected spillage, then leave the fan running and evacuate the area. Subject to
the hazard assessment and local considerations, it may be that personnel with
breathing apparatus would have to return to open windows and ensure that all
hazardous vapours or gases had been dispersed.
It is recommended that replacement carbon filter/s are kept available at short
notice for such an event.
WARNING:
If a spill exceeds the capabilities of the Airone FC750, it is likely to exceed the capabilities
of carbon filtration facemasks. This means that only an air or oxygen cylinder based
breathing apparatus could provide adequate protection.
