II . Unpacking Your Cabinet

This chapter aims to provide relevant information on how to handle the cabinet properly upon receipt. Failure to
follow these instructions may damage the cabinet. We strongly advise you to read this chapter carefully before
proceeding further.

2.1 Step-By-Step Procedure

1. Inspecting the Crate, Pallet, Boxes.

» Upon receipt of your new cabinet, inspect all cartons. If there is any visible damage to the exterior please

refer to Damaged Freight Claim Information on our website.

2. Moving the Pallet.

» The pallet is designed to protect our cabinet from any foreseeable circumstances. However, excessive

impact onto the boxes or pallet may also damage the cabinet. Prevent any direct impact or hitting to the
pallet when moving.

» When lifting the pallet, always ensure that the floor jack or mechanical lift truck has fully entered under

the pallet in order to achieve stability. Failure to do so will increase the risk of the pallet falling off the
floor jack or mechanical lift truck during handling. Please use a suitable extension bar when necessary.

3. Opening the Boxes.

» If you did not receive one or more of the parts listed on the packing checklist, or if any of the items are

damaged, please refer to the Damaged Freight Claim Information on our website.

6 \ USER OPERATION MANUAL: Cole-Parmer Basic Ductless Fume Hood Series

4. Removing the Packaging Material.

» The cabinet is protected by extruded polystyrene foam, cardboard and/or shrink-wrap.
» If you find any damage during this stage of unpacking please refer to the Damaged Freight Claim Information

on our website.

» We recommend leaving the cabinet secured with straps to the pallet until the cabinet is located in its

approximate final position to facilitate ease and safety in handling.

Note: Choosing the best location for your cabinet in order to achieve optimum operating performance
is determined by a number of factors. Please refer to the next chapter for some guidelines.

5. Moving the Cabinet.

» When lifting the pallet with the cabinet, always ensure that the floor jack or mechanical lift truck has fully

entered under the pallet. This is to increase the stability of the cabinet and reduce the risk of the cabinet
falling down. Please use a suitable extension bar when necessary. During the moving of the cabinet,
ensure there is enough distance between the supports of the pallet and the ground. Dragging the pallet
against the ground will damage the pallet and possibly your new cabinet.

» When removing cabinet from pallet or placing cabinet onto pallet, use at least two people.

6. Removing the Strapping.

» Remove the strapping by cutting it at a safe position to prevent any scratching the surface of your new

cabinet.

» Do not discard the packaging material for your cabinet until you have checked all of the components, installed

and tested the unit.

III . Installing Your Cabinet

3.1 Choosing a Suitable Location

Location impacts the nature and extent of external airflow disturbances, which may affect performance of the
cabinet when it is exposed to these disturbances.

When installing the cabinet, it should be located as far away as possible from sources of airflow disturbance and
in an orientation which optimally shields the airflow of the cabinet from all external airflow disturbances. Please
note that the cabinet should not be placed close to another cabinet.

Please follow these guidelines when choosing a suitable location for your cabinet:

• The location must be far away from:

» Personnel traffic flows.
» Air vents (in and out).
» Doors and windows.
» Any other sources of disruptive air currents or air drafts.

• If drafts or other disruptive air currents exceed the face velocity of the filter, the potential exists for

contaminated air to enter the work zone of the cabinet.

• A minimum distance of 50 cm (20 in.) to the top of the ceiling is recommended for blower changing
purposes.

• A clearance of 183 cm (6 ft) in front of the cabinet is strongly advised in order to maintain proper airflow.

3.5 Performance Validation / Certification

After installation and prior to use, cabinet performance must be validated and certified to factory standards. The
following tests should be performed:

Airflow Velocity
The testing methods and equipment required are specified on the test report. It is recommended that these tests

be performed only by a qualified technician who is familiar with the methods and procedures for certifying these
types of cabinets.

3.6 Importance of Performance Validation / Certification

An airflow velocity value that falls below the value specified inside the test report will not provide adequate
operator protection.

18 \ USER OPERATION MANUAL: Cole-Parmer Basic Ductless Fume Hood Series

4.2 Cabinet Operating Procedure

• The fume hood should only be operated with the correct filter installed for the application. Refer to

Filter Information - page 27 for further information. The ductless fume cabinet must not be used for laboratory

work in which chemicals of different types are used that do not match the filter type or that the primary chemicals
and their byproducts are not known. The ductless fume cabinet should not be used for different chemical
processes where chemicals from the different processes could react in the filter.

• 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 airflow and the filter condition of the cabinet on a regular basis. This is covered in Maintenance -

page 21.

• Please note, filter 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 cabinet and the retardation of the
chemical in the filter matrix.

• Cole-Parmer fume hoods have been designed to handle fumes and vapors given off during everyday
laboratory procedures. These will be at the parts per million (PPM) level in the air stream entering the filter
block. It is not recommended that large quantities of solvents or acids be used or boiled off in the cabinet.

• In the event of a large spillage in the cabinet, the amount of fumes entering the filter block may temporarily
reduce the efficiency of the filter. 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 filters must be changed, as the heat of wetting may reduce the efficiency of the
filter. After a period of stabilization, the old filters may be reused, providing they have not reached the
saturation level.

• The electrical equipment in the cabinet such as the lights and controls are not in the dirty air stream of the
system. The system should not be used in a flammable room atmosphere. Special modified cabinets can be
provided for use in these areas. Contact Cole-Parmer for further information on these applications.

• Operators should avoid sudden movements within the fume cabinet, such as rapid opening or closing of the
sash window, as this may cause temporary reversal of the airflow.

• The operators should maintain the normal safety equipment and procedures for dealing with hazardous chemicals.

WARNING!

» Do not use a gas flame (Bunsen burners) whenever possible, as it interferes with airflow.
» Do not change the original blower speed of the cabinet unless the change is required by a decrease in

measured air velocity. Adjustment should be made only by a qualified technician. Do not operate the cabinet

if fan fails to run.
» Minimize arm movement. Move arms in and out of the cabinet slowly to avoid disrupting cabinet airflow.
» 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.

19 \ USER OPERATION MANUAL: Cole-Parmer Basic Ductless Fume Hood Series

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-filters become blocked, the velocity of the cabinet will begin to fall and will eventually cause the

airflow alarm to illuminate.
» Manual checking of the main filters by the use of a Gastec™ or Draeger™ test kit will confirm the condition of

the filters.

5.2 Manual Monitoring

Manual monitoring of the cabinet should be carried out at least once per year, as this will ensure the monitoring
systems are all within calibration and performing correctly.

Airflow Measurements

The inflow velocity of the hood should be checked with the sash at the correct operating height using an
anemometer such as a hot wire, vane anemometer or propeller type. Depending on the size of the cabinet, a
series of readings are to be taken at the front opening; these are to be recorded on a service sheet or system
log sheet.

Manual Filter Testing

The condition of the filter is to be checked using a Gastec or Draeger test kit. Boiling off a suitable chemical
normally used in the cabinet or a controlled release should challenge the filter. Examples can include alcohols,
toluene and trichloroethylene.

For testing acid filters (acid adsorbing) or multi combination layered filters incorporating an acid layer, use sulfur
dioxide gas (SO2) at 2 bubbles per second through water.

The readings should be below your Country’s Occupational Exposure Limit (see Filter Information - page 27).

The results are to be recorded on a service sheet or system log sheet.
If a significant amount of chemical is noted at the exhaust of the system, the main filters should be changed.

20 \ USER OPERATION MANUAL: Cole-Parmer Basic Ductless Fume Hood Series

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 officer.

Regular preventative maintenance on the cabinet will reduce the possibility of hazard to the operator and ensure
reliable performance from the cabinet.

WARNING! Before attempting inspection and repairs to the cabinet, please ensure main power to
the system has been removed and that the power lead has been removed. It should also be noted that

fume cabinets are sometimes used to contain and protect users of the cabinet from hazardous
or harmful substances. Before commencing this schedule it is important to ensure the cabinet 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 Lights

Ensure that the light diffuser is clean before switching the system on. Check that the light is in working condition.

6.5 Airflow

Check and record the inflow air velocity at the working aperture as follows: Using a calibrated hot wire or vane
anemometer or similar approved airflow meter, take a minimum of 5 readings across the fume cabinet aperture as
shown below. Calculate the average airflow, which should be greater than 0.5 m/sec or 100 fpm +/- 10%.

The readings should be recorded on the service sheet or system log.

21 \ USER OPERATION MANUAL: Cole-Parmer Basic Ductless Fume Hood Series

6.6 Calibration Instructions

Testing the Low Airflow Alarm

» Ensure the fitted pre-filters are new. Switch on the cabinet; the red/amber neon should not be

illuminated.
» Switch the unit off. Block the pre-filter using paper or cardboard to permit airflow of <0.3 m/sec or 60 fpm.
» Switch the unit on. The red/amber neon should illuminate. If not, the calibration should be reset.

Calibration

The low airflow alarm operates using a differential pressure switch to detect a “high vacuum” situation when the
pre-filter is blocked or blocking up. The pressure switch is calibrated and tested prior to leaving our factory and
under normal circumstances will not require any adjustment.

» With the cabinet running and the pre-filter blocked as described above, locate the grey pressure switch

through the hole in the right hand sidewall. Adjustment is made by turning the small screw in the end of the

switch. (See Photograph #16 - page 14).
» Adjust the screw to make the alarm show. You may have to repeat these steps to ensure an accurate

setting has been achieved.
» Remove the blockage and restart the machine. The red/amber neon should not be illuminated.

22 \ USER OPERATION MANUAL: Cole-Parmer Basic Ductless Fume Hood Series

6.7 Changing Out Filters

WARNING! Ensure persons removing filters 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 filters will depend on the application of the hood. If
an activated carbon filter is used with hydrocarbon solvents, the filter will retain the solvents without loss, and
can be removed in the laboratory. The used filter should be sealed into a plastic bag prior to disposal,
preferably by incineration.

If the filter has contained any dangerous materials such as asbestos dust or radioactive chemicals,
operator protection is advised, including the use of a respirator. The used filters may require disposal by
a specialist company.

NOTE: CONSULT YOUR SAFETY OFFICER OR INDUSTRIAL HYGIENIST BEFORE REMOVING OR
DISPOSING ANY FILTERS.

Pre-Filters

The pre-filter is located below the main filter. Remove the perforated pre-filter tray. Remove the old pre-filter and
place it into a bag. Seal for disposal. Refit the new filter and refit the pre-filter tray.

Main Carbon / HEPA Filter
