Below the worktop is the carbon filter, pre-filter and fan and flexible hoses for
water andwasteservices.
The control panel is fitted on the top front panel.
A filter saturationpanel is availablewhich indicateswhen the filter needsto be changed'
An alarmwill soundfor low airflow or fan failure.
The fume cupboard is designed to keep noxious and dangerousfumes within the
cabinet and isolated from the operator. The contaminatedair is passed through a
carbonfilter to remove hazardousfumes,vapour or particles'
The carbonfilter is designedto absorbeffrciently at aface velocity of plus 0.3 m/secup

The sense of smell is very sensitive for certain chemicals, such as ammonia or

The worktop is dished to contain any spillage, and can be fitted with gas and water

To ensure maximum performance and operator safety the following points should be
followed:-
l.
Sashstopsshouldbe kept in the lockedpositionso thatthe sashopeningis kept at the
workingheightof 400mm. It shouldnot be operatedwith the sashin the fully opened
position.
2.
The extractionfan shouldbe turnedoffwhen not in use'

The front lip aerofoil cill shouldalwaysbe in position.
4.
The back baffle should haveno obstructionbehind the baffle, or blocking the lower slot
opening.
5.
Spring loadedadjustmentscrewsin the sashguide track can be turned in or out to vary
the grip of the guide on the sash. This allows the sashto slide freely, and also takesup
wear.
6.
Any chemicalsstoredin the fumecupboardshouldbe in coveredcontainersor capped
bottles.
7.
Equipmentused should be placedinsidethe working areabefore start-up,to prevent

I OPERATINGINSTRUCTIONS
SECTION7.0
7|
The fume cupboardmust only be operatedwith the correct filter installed.
72
To start the units, switch the power switch on. The fan will automatically run to give
0.5m/s.
7.3
Checkthe airflow and filter saturationon a regular basis.
74
The face velocity at the working aperture (and therefore containment of fumes) is at a
maximumwith the sashat 400mm from the worktop.
75
Bunsenburner or other heat source should not be placed too close (<1500mm) to the
sideor backpanels.
7 .6
AII-unitsare providedwith a G.R.P. spillagetray that hasgood chemicalresistance.
7.6
Filter blocks do not absorbcarbon monoxide or hydrogen. However, small quantities
(such as used in schools)will not presenta hazardbecauseof the large dilution factor
from the airflow through the fume cupboard, and retardation or the chemical in the
filter matrix
7.7
The fume cupboardsare designedto handlefumes and vapoursgiven off during normal
laboratoryprocedures.
7.9
Always keepa spareset of filters
7.10
High concbntrationsof fumes entering the filter block may temporaily reduce the
filtration efficiency. For this reason any major spillage within the fume cupboard
shouldbe clearedup quickly.
7.11
Following a major spillage, the main filters must be changed.After stabilisation,the
original filters can normally be re-used,provided saturationhas not beenreached.

The alarm is the red light at the front of the unit. In normal operation,the red
light will not
light up.
If the red indicator lamp starts to flash on intermittently or stays on, the pre-filter
is starting to
block with dust and an
reading should be taken at the apertureto determine if the

ntrrER TYPES& MONITORING I SECTION8.0
Pre-Filters
Filtrete pre-filter. This is a high performancepre-filter, designedto removeparticulates
from the airstream. The filter material is based on electrets,which are permanently
changeddielectrics. They remove particulatesfrom polluted air by strong electrostatic
forcesgeneratedby the fibres from which they are made.
The combinationof a strong electric charge and open structureprovides a filter with
high efficiency,low airflow resistanceand high loading capacity. Measuredeffrciency
figuresforparticles in the 0.5 - 2.O-micronrangeis+99Yo,with loadingcapacitiesup
to ll3g/msquared. Filtrete will remove fine particles,aerosols,mists, smokeand dust.
82
Main Filters
CA.SCHOOL Filter - The CA.SCHOOL filter has been specially formulated to
'A'
absorbthe normal range of chemical fumes generatedin Schoolsduring GCSE and
Level classes.
83
Monitoring
If the pre-filtersare blocked, the airflow will'be reducedat the fume cupboardaperture.
If the main filters are saturated,they will ceaseto removethe fumes effectively.
The Fume Cupboardsare fitted with:
1.
2.
3.
A low airflow alarm
A filter saturationdetector
An or/offpower switch
If an odour is noticed, it is sensibleto check the fume cupboard. However, it must be
rememberedthat the senseof smell is very sensitivefor somechemicals(e.g. ammonia
or hydrogen sulphide) and a slight smell does not mean that the exhaust levels of
chemicalhaveapproachedthe maximum acceptableconcentration.
84
Manual Monitorins
Manual mohitoring should be carriedout yearly to checkthe fume cupboardsystems.
Airflow Measurements
An anemometeris used to check the airflow (face velocity) at the working aperture,
with the lower panel down. A minimum of six readingsshould be taken acrossthe
working aperture.
