IV. Operating Your Vent-Box
4.1 Control System
Basic Control Panel (Standard)
The basic control panel is standard and includes an On/Off switch and Filter Blockage alarm. If the indicator
lamp starts to ash intermittently or stays illuminated, the lters are beginning to become blocked and airow
may be reduced to unsafe levels. Check airow and/or replace lters as needed. Alarm may be reset and tested.
FSA Control Panel (Optional)
The optional FSA controller offers limited detection of low concentrations of hydrocarbon, some gases and
organic acids. Audio and visual alarms alert users if lter saturation reaches preset thresholds. An Hour Counter
with preset alarm intervals for pre-lter and main lter change out and Low Airow alarm are also included.

12 \ USER OPERATION MANUAL: Vent-Box
4.2 Vent-Box Operating Procedure
• The Vent-Box should only be operated with the correct lter installed for the application. Refer to Filter Information
– page 19 for further information. The Vent-Box must not be used for laboratory work in which chemicals of different
types are used that do not match the lter type or that the primary chemicals or their byproducts are not known.
The Vent-Box should not be used for different chemical processes where chemicals from the different processes
could react in the lter.
• To start the system, apply power to the system and switch on the green power On/Off switch. The lights
and fan will automatically turn on.
• Check the airow and the lter condition of the Vent-Box on a regular basis. This is covered in
Maintenance - page 14.
• Please note, lter blocks do not absorb carbon monoxide or hydrogen. Small quantities will not cause hazards
because of the large dilution factor from the amount of air passing through the unit and the retardation of the
chemical in the lter matrix.
• Air Science products have been designed to handle fumes and vapors given off during everyday laboratory pro-
cedures. These will be at the parts per million (PPM) level in the air stream entering the lter block. It is not recom-
mended that large quantities of solvents or acids be used or boiled off in the unit.
• In the event of a large spillage in the Vent-Box, the amount of fumes entering the lter block may temporarily
reduce the efciency of the lter. For this reason, any major spillage must be cleared up immediately, preferably
using spillage absorption granules rather than paper, which may aggravate the evaporation of toxic fumes from the
spillage area.
• Following a major spillage, the lters must be changed, as the heat of wetting may reduce the efciency of the lter.
After a period of stabilization, the old lters may be reused, providing they have not reached the saturation level.
• The electrical equipment in the Vent-Box such as the lights and controls are not in the dirty air stream of the system.
The system should not be used in a ammable room atmosphere. Special modied units can be provided for use in
these areas. Contact Air Science for further information on these applications.
• Operators should avoid sudden movements within the Vent-Box, such as rapid opening or closing of the sash
window, as this may cause temporary reversal of the airow.
• Operators should maintain the normal safety equipment and procedures for working with hazardous chemicals.
WARNING!
»Vent-Box should not be used in a ammable room atmosphere.
»Do not use a gas ame (Bunsen burners) whenever possible, as it interferes with airow.
»Do not change the original blower speed of the unit unless the change is required by a decrease in measured
air velocity. Adjustment should be made only by a qualied technician. Do not operate the Vent-Box if fan
fails to run.
»Minimize arm movement. Move arms in and out of the unit slowly to avoid disrupting airow.
»Use absorbent pads on the work surface where appropriate to minimize splatter and aerosol generation
in case of spillage.
»Keep lids/covers on all containers, dishes or sample plates.
»The operators should maintain the normal safety equipment and procedures for dealing with hazardous
chemicals.

V. Monitoring
5.1 General
The purpose of the monitoring program is to ensure consistent reliability from the system. This is achieved by
checking the following:
»If the pre-lters become blocked, the velocity of the unit will begin to fall and will eventually cause the
lter blockage alarm to illuminate.
»Manual checking of the main lters by the use of a Gastec™or Draeger™ test kit will conrm the condition
of the lters.
5.2 Manual Monitoring
Manual monitoring should be carried out at least once every year, as this will ensure the monitoring systems
are all within calibration and performing correctly.
Manual Filter Testing
The condition of the lter is to be checked using a Gastec or Draeger test kit. Boiling off a suitable chemical
normally used in the Vent-Box or a controlled release should challenge the lter. Examples can include alco-
hols, toluene and trichloroethylene.
For testing acid lters (acid adsorbing), or multi combination layered lters incorporating an acid layer, use
sulphur dioxide gas (SO2) at 2 bubbles per second through water.
The readings should be below your Country’s Occupational Exposure Limit (see Filter Information – page19).
The results are to be recorded on a service sheet or system log sheet.
If a signicant amount of chemical is noted at the exhaust of the system, the main lters should be changed.

VI. Maintenance
6.1 General
In some countries it is mandatory to maintain written records of checks, tests and repairs carried out on safety
equipment. These records must be kept for 5 years. A full list of Occupational Exposure Limits should be
obtained from your safety ofcer.
Regular preventative maintenance on the Vent-Box will reduce the possibility of hazard to the operator and
ensure reliable performance.
WARNING! Before attempting inspection and repairs to the Vent-Box, please ensure the power to
the system has been removed and that the power lead has been removed. It should also be noted that
these units are sometimes used to contain and protect users of the Vent-Box from hazardous or harmful
substances. Before commencing this schedule, it is important to ensure the unit is safe to work on.
6.2 General Cleaning
Wipe down the unit with only soapy water.
6.3 Pre-Filters
Check condition and replace if required.
6.4 Changing Out Filters
WARNING! Ensure persons removing lters are made aware of any potential hazards and that they are
provided with any necessary protective clothing and equipment.
Hazards associated with the removal and disposal of used lters will depend on the application of the Vent-
Box. If an activated carbon lter is used with hydrocarbon solvents, the lter will retain the solvents without
loss, and can be removed in the laboratory. The used lter should be sealed in to a plastic bag prior to dis-
posal, preferably by incineration.
If the lter has contained any dangerous materials such as asbestos dust or radioactive chemicals, operator
protection is advised, including the use of a respirator. The used lters may require disposal by a specialist
company.
NOTE: CONSULT YOUR SAFETY OFFICER OR INDUSTRIAL HYGIENIST BEFORE REMOVING OR
DISPOSING ANY FILTERS.
