IInnttrroodduuccttiioonn
Congratulations on the purchase of a Labconco Paramount
Enclosure, commonly called a ductless fume hood. Unlike traditional fume
hoods, the Paramount Ductless Enclosure is considered green as it conserves
energy because it requires no ducting. The Paramount Ductless Enclosure
is a self-contained work station that protects the operator from specified
vapors and/or particulates released in the work area, through the use of
carbon filters and/or HEPA filters. Typical organic solvents, formaldehyde,
acid gases, ammonia, amines, particulates, and powders are contained inside
the enclosure to protect the operator and then filtered. Purified air is drawn
from the filters and returned to the room. Vapors are adsorbed on activated
carbon filters or impregnated carbon filters and particulates/powders are
filtered by the HEPA filter.
Each Paramount Ductless Enclosure includes the Safety-First™ Vapor
Sensor that detects filter saturation and alerts the operator to replace the
filters. The early warning provided by the Safety-First Vapor Sensor
provides the user ample time (5-10% remaining filter life) to complete work
in process before changing the filters. The Safety-First Vapor Sensor
includes a primary and secondary sensor for redundant monitoring and the
sensor detects typical organic solvents, smoke particulates, ammonia gases,
formaldehyde gases, and hydrogen sulfide gases. The Paramount Ductless
Enclosure is the result of Labconco’s years of experience in the design and
manufacture of fume hoods and ductless hoods.
The Paramount Ductless Enclosure offers many unique features to enhance
safety, performance, and ergonomics. Safety is illustrated with the SafetyFirst Vapor Sensor. Performance and Safety are illustrated with validated
containment and patented aerodynamic features (U.S. Patent No. 6,461,233).
Ergonomics is illustrated with the patented inclined design (U.S. Patent No.
D538,941). To take full advantage of all features, please acquaint yourself
with this manual and keep it handy for future reference. If you are unfamiliar
with how ductless enclosures operate, please review Chapter 4: Performance
Features and Safety Precautions, before you begin working.

Before you install the Paramount Ductless Enclosure, you need to prepare
your site for installation. A dedicated source of electrical power should be
located near the installation site to power the ductless enclosure and other
apparatus. Additionally, the enclosure should be strategically placed in the
lab to provide efficient workflow.
Carefully read this chapter to learn the requirements for your installation site:
• The support and stability requirements.
• The location and air current requirements.
• The exhaust and blower requirements.
• The electrical power requirements.
• Space requirements.
Refer to Appendix B: Dimensions for complete enclosure dimensions.
Refer to Appendix C: Specifications for complete enclosure electrical and
environmental conditions, specifications and requirements.
Support and Stability Requirements
At a minimum, the supporting structure usually consists of a base cabinet or
stand and a chemically resistant work surface. Please consider the following:
• Work surfaces should be of a thick rigid material that remains stable.
• A bench that is rigidly mounted to the floor or fixed to the wall may
be appropriate.
• Tubular stands or mobile benches with locking casters may be
appropriate.

Chapter 2: Prerequisites
Location and Air Current Requirements
The Paramount Ductless Enclosures have been designed to contain hazards
by negating typical cross drafts and turbulence within the opening. However,
it is recommended that the enclosure be placed in an area to avoid:
• High traffic areas where walking might cause an air disturbance or be a
nuisance.
• Overhead or wall HVAC diffusers, fans, radiators or other lab equipment
producing air currents.
• Near doorways or windows that may be opened.
Exhaust and Blower Requirements
The Paramount Ductless Enclosure uses a green, 95% energy efficient,
electronically-commutated motorized (ECM) impeller to draw room air past
the operator and through the enclosure (see Appendix D for power usage by
model). This contaminated air is passed through filters and exhausted out the
top of the enclosure. The filtered exhaust air is normally recirculated into the
laboratory or may be exhausted outside with the addition of the Canopy
Exhaust Connection and remote blower listed in Chapter 7. Contact
Labconco for blower sizing assistance for exhausting to the outside.
Electrical connections are covered in Chapter 2 for this configuration.
Data for the enclosure’s exhaust volume, noise pressure and face velocity are
listed on the next page in chart form for each Paramount Ductless Enclosure
model at face velocities of 60, 80, and 100 fpm. All models are shipped to
operate at 75-80 fpm, but can be reset by the Safety Officer or certification
technician through a password protected menu.
Important Note: If the enclosure is connected directly to a house exhaust system,
an adjustable damper (or valve) must be installed to control the airflow properly.
This is equally important when a house exhaust system is controlling multiple
ductless enclosures. See Chapter 7 for information on accessories.

Chapter 2: Prerequisites
Electrical Requirements
Standard duplex electrical receptacles should be nearby for connecting the
Paramount Ductless Enclosure and other equipment. The enclosures include iris
pass-through ports to allow electrical cords through the back of the enclosure
without leaving a large hole for contaminants to escape. (See Appendix C for
amperage.)
There is no provision for controlling a remote blower for exhausting air from the
Paramount Ductless Enclosure. If remote blower control is required, a qualified
electrician may connect a wall-mounted power outlet switch receptacle nearby so
that the switch controls both the remote blower and the outlet. The power cord
for the Paramount is then plugged into this outlet.
Space Requirements
The dimensions for the different models are shown in the chart in Chapter 2 and
detailed in Appendix B: Dimensions. To convert inches to millimeters, multiply
by 25.4.

Chapter 3: Getting Started
Unpacking the Enclosure
We recommend that you do not remove the enclosure from its shipping
container until it is ready to be placed into its final location. Move the unit
by placing a flat, low dolly under the shipping skid, or by using a floor jack.
Carefully remove the shrink-wrap or carton on the enclosure and inspect it
for damage that may have occurred in transit. If damaged, notify the delivery
carrier immediately and retain the entire shipment intact for inspection by the
carrier.
Note: The United States Interstate Commerce Commission rules require that
claims be filed with the delivery carrier within fifteen (15) days of delivery.
Note: Do not return goods without the prior authorization of Labconco.
Unauthorized returns will not be accepted.
Note: If the enclosure was damaged in transit, you must file a claim directly
with the freight carrier. Labconco Corporation and its dealers are not
responsible for shipping damages.
Do not discard the packing material until you have checked all of the
components and tested the enclosure.
Do not move the enclosure by tilting it onto a hand truck.
Set Up the Ductless Enclosure on a Supporting
Structure and Work Surface
When installing the enclosure onto a chemical-resistant work surface or
benchtop, ensure that the structure can safely support the combined weight of
the enclosure and any related equipment. See Chapter 7: Accessorizing the
Paramount Ductless Enclosure for appropriate work surfaces, stands,
and cabinets. The work surface should be at least as wide as the enclosure
to properly support it. The front of the enclosure should be aligned within
0.3" of the front of the work surface as shown in Figure 3-1. Mounting holes
are provided in the Labconco accessory work surfaces to secure the
enclosure. RTV Silicone sealant can be applied to seal the work surface to
the enclosure.
Work Surface Specifications
The work surface should be smooth, rigid, and durable. The surface should
be non-porous and resistant to the powders, solvents and chemicals used in
conjunction with the Paramount Ductless Enclosure.

Product Service 1-800-522-7658
Chapter 3: Getting Started
Work Surface and Enclosure Installation
1. Level the base cabinets and the work surface. Work surface should be
placed flush with the front of the stand or base cabinet as shown in
Figure 3-1.
2. Identify and position the work surface ensuring the mounting holes
will align with the four screw locations on the base of the enclosure.
(Rear mounting holes are located close to the rear edge.)
3. Secure the work surface to the base cabinet with a structural adhesive
or silicone sealant.
4. Before moving the enclosure, insert the supplied mounting screws in
the four holes. Allow a minimum of 1/8" clearance under the head of
the screw for positioning the enclosure. For the stainless work
surfaces, use a #10-24 x 3/8" hex washer head screw (Labconco part
number 1885806).
5. Place the enclosure on the work surface and slide the rear flange and
front air foil flanges under the mounting screw heads.
6. Tighten the four screws to complete the installation.
7. If desired, apply RTV silicone to seal the work surface and enclosure.

Chapter 3: Getting Started
Install Carbon Filters and/or HEPA Filters
Refer to Figure 3-2 for a view of the filter loading compartment with the
front panel removed. The Paramount Ductless Enclosure ships without
filters that must be ordered separately. It is highly recommended that
an extra set of new filters be on hand on a continuous basis.
To remove the front panel, use a Phillips screwdriver to loosen the two
screws holding the front panel in position; slide the front panel forward and
then up to remove. The filter loading compartment is hinged and supported
by gas spring cylinders. Lift the handle up and remove the cardboard
packing. The cardboard packing will be replaced with filters that always
stack two high.
The Paramount Ductless Enclosure has seven different filter types identified
below:
6938100 HEPA Filter, 15" x 18" x 1.5", 99.99% efficient particulate on 0.3 micron
6938200 Activated Carbon Filter, Organic Vapor 7.5 lbs.
6938201 Impregnated Carbon Filter Acid-Sulfur 10 lbs.
6938202 Impregnated Carbon Filter, Ammonia-Amine 11 lbs.
6938203 Impregnated Carbon Filter, Formaldehyde-Formalin 10 lbs.
6938204 Mixed Bed Carbon Filter, Org. Vap., Acid-Sul., Ammon, Form (25% Mix) 10 lbs.
6938205 Impregnated Carbon Filter, Radioisotope 10 lbs.
All impregnated Carbon Filters, specific chemical treated, have an organic
vapor capacity of 25%. Mixed Bed Carbon Filters have an organic vapor
capacity of 50%. For example, the Impregnated Acid Filter has 25% of 10
pounds or 2.5 pounds of organic vapor capacity. Thus, a common application
using solvents with acids would require one Activated Carbon Filter for
organic vapors and one Impregnated Acid Filter for acid vapors.
Any combination of two filter types may be used. Filters are always loaded
with the gasket side up. If placing the Paramount Ductless Enclosure in a
clean room, always place the HEPA filter above the carbon filter to eliminate
any trace carbon particles from entering the clean room. Load the stacked
filters into the individual filter compartments. The Paramount model sizes,
filter compartments, and number of filters are listed below for installation
convenience.

Filter Installation
Connect the Electrical Supply
Simply connect the 115V power cord supplied to the IEC electrical supply
plug on the back of the enclosure. For 230V, the same procedure applies
except it is shipped without a plug. Install the appropriate plug for your
electrical specifications per local codes. (See Appendix C for amperage.)
Set Filter Life and Filter Check Timers
Once the filters are installed and electrical power is connected, it is necessary
to set the Filter Life Timers in the Filter Setup menus described in Chapter 5:
Using the Ductless Enclosure. Consult the separate Paramount Chemical
Guide, Appendix E: Estimated Filter Life Calculation, and/or Labconco

Chapter 3: Getting Started
Initial Safety-First™ Vapor Sensor Warm Up Period
The Safety-First™ Vapor Sensor includes a 5V, 0.28W integrated heater and
any detectable gas that accumulates during shipment must be driven off the
organic sensor over an initial 10-30 minute warm up period with the blower
activated. Refer to the Diagnostic Program Screen for Organic Sensor on
page 32 in Chapter 5 to view the display of the millivolt levels of the Vapor
Sensor. With new filters installed, the Organic Sensor should read between
1300-1500 millivolts after the initial 10-30 minute warm up period with the
blower running. All filters should be changed upon completion of work once
the Organic Sensor sees an increase of 400-500 millivolts with the display
indicating “Replace Filters.”
Reset or Change the Airflow Face Velocity
(If Necessary)
The face velocity for the Paramount Ductless Enclosure has been preset at the
factory between 75-80 fpm. Important Note: Transport, altitude, and
temperature differences may require a reset of the “Calibration” of the
“Pressure Sensor” as outlined in Chapter 5: Using the Ductless Enclosure.
When “Calibration” of the “Pressure Sensor” is reset, it is best to try the
previously calibrated values of motor speed and airflow face velocity and
then confirm the average face velocity through the enclosure sash opening.
Adjust the motor speed and airflow face velocity as necessary after
confirmation. Average face velocity measurements are made using a
calibrated thermal anemometer and taking an average across the sash opening
at 5" directly below the sash handle.
Additionally, the same “Calibration” menu in Chapter 5 should be used to
change the face velocity to another value. For most applications, 75-80 fpm
is ideal. However, there are some requirements for 100 fpm. Furthermore,
the face velocity alarm has been preset at the factory at 60 fpm. If needed,
follow the “Calibration” menu for the “Airflow Alarm” in Chapter 5 and
adjust the alarm value between 10-20 fpm below the actual face velocity.
The Paramount Ductless Enclosure has been set up to accept the SmartFlow™ feedback system. The Smart-Flow feature adjusts the motor speed
automatically for filter pressure drop, barometric pressure, and room
temperature, and maintains constant airflow velocity at the calibrated value.
Note: At altitudes above or below 900 feet, the Paramount must be
recalibrated to account for significant pressure changes that will have an
effect on face velocity. Face velocity measurements are always made using a
calibrated thermal anemometer and taking an average across the sash
opening. Follow the “Calibration” menu for “Pressure Sensor” as outlined in
Chapter 5: Using the Ductless Enclosure for recalibration of face velocity.
Product Service 1-800-522-7658

Chapter 3: Getting Started
Validate the Enclosure
To determine the actual face velocity at the sash opening, airflow velocity
readings are taken. Each Paramount Ductless Enclosure has been preset at
75-80 fpm. The “average face velocity” is achieved by taking readings
across the enclosure with the readings 6" from the ends and evenly spaced
every 12". Readings are measured at 5" directly below the upper sash handle.
Refer to Chapter 2 for proper airflow volumes for your particular model.
The Paramount Ductless Enclosures have been tested at Labconco’s airflow test
facility per ASHRAE 110-1995. All enclosures achieve an “as manufactured
rating” of less than 0.05 part per million (ppm) at 4 liters per minute (lpm); AM
<0.05 (Consult Labconco for individual ratings). For particulate powder
validation, Labconco had containment testing performed to validate the
enclosures for naproxen sodium powders. The Paramount Ductless Enclosures
demonstrated excellent containment when used by an operator using excellent
technique and good containment when used by an operator using marginal
technique. While no enclosure can compensate for improper technique, these
tests confirm that the Paramount Ductless Enclosures provide a safe working
environment. For copies of these validation reports, contact Labconco at 800821-5525 or 816-333-8811.
Seal the Enclosure to the Work Surface
When the enclosure has been set in place, it can be sealed at the work surface
to prevent spilled materials from collecting under the walls. A bead of
silicone sealant is recommended to seal the enclosure to the work surface.
Connecting to the Exhaust System (If Applicable)
WARNING: The weight of the exhaust ductwork system must be
supported independently of the enclosure superstructure or damage may
occur.
The exhaust system should be installed by a qualified HVAC contractor.
Normal operations with the Paramount Ductless Enclosure are exhausted into
the room and the accessory Canopy Exhaust Connection is not required. The
Canopy Exhaust Connection aids in the further removal of chemicals beyond
the filters or applications where a higher degree of powder and particulate
removal is required. However, if desired, the Canopy Exhaust Connection
(see Chapter 7) accessory has been designed to accept 6" diameter ductwork.
Review Chapter 2 for exhaust prerequisites and review Chapter 7 for ordering
blower exhaust equipment. Consult Labconco should you require help sizing
your blower for the exhaust volume and system static pressure loss. To
ensure compatibility, the selected exhaust duct material should match the
enclosure, procedures and chemical applications.

Chapter 4: Performance Features and Safety Precautions
High Performance Containment
The Paramount Ductless Enclosures use patented technology to direct air into
and through the contaminated air chamber (U.S. Patent 6,461,233). The
containment enhancing and aerodynamic designs of the lower CleanSweep™ Air Foil, upper sash foil, side air foils, upper dilution air supply,
and zoned rear perforated baffle all work in concert to produce horizontal
airflow patterns that significantly reduce chemical concentrations through the
work area (illustrated in Figure 4-2). The unique lower air foil shape and
Clean-Sweep™ openings sweep the work surface and create a constant
protective barrier from contaminants. The radiused upper sash foil includes
an open air passage directly atop the sash foil into the enclosure chamber and
directs chemical concentrations away from the sash opening. The side entry
air foils allow turbulence-free air to enter the enclosure from the sides and
allow clean air to sweep the interior walls. The upper dilution air supply
provides by-pass air from above the work surface to constantly bathe the
inside of the sash and upper chamber with clean air to reduce chemical
concentrations. The zoned rear perforated baffle directs horizontal laminar
air streams to the three zones to minimize the potential for air to roll forward
preventing contaminants from moving toward the sash opening.

Chapter 4: Performance Features and Safety Precautions
Safety-First™ Vapor Sensor
The Safety-First™ Vapor Sensor detects filter saturation in the exhaust to
alert the operator to replace the filters. The early warning provided by the
Safety-First Vapor Sensor provides the user ample time (5-10% remaining
filter life) to complete work in process before replacing the filters. The early
warning signals with an intermittent beep and the LCD display message alerts
the user to replace filters. The final warning signals with a constant alarm
and the LCD display message alerts the user to replace filters. The SafetyFirst Vapor Sensor includes a primary and secondary backup sensor for
redundant monitoring. Both sensors detect typical organic vapor solvents,
smoke particulates, ammonia gases, formaldehyde gases and hydrogen
sulfide gases. The Safety-First Vapor Sensor has an optimal detection range
of 1-10 ppm. Typical concentrations tested by Labconco for chemicals in
separate chemical families are listed in order of sensor sensitivity as follows:

Smart-Flow™ Airflow Monitor
The Smart-Flow™ Airflow Monitor continuously monitors airflow and
displays face velocity. An audible/visual alarm alerts the user to low airflow
conditions. The Smart-Flow Airflow Monitor enables the motor speed to
automatically adjust for conditions such as temperature, barometric pressure,
and filter loading and maintain constant programmed airflow speed. The
Smart-Flow feedback maintains constant airflow speed through the use of
constant velocity pressure measurement accomplished with a pitot tube and
pressure sensor mounted on the control board. Transport, altitude, and
temperature differences require the airflow re-calibration steps as outlined in
Chapter 5 and 6. Use the “Calibration” menu in Chapter 5 to reset the
“Pressure Sensor” values for “motor speed” and “airflow face velocity.”
Quiet, Energy-Efficient ECM Impeller
The electronically commutated motorized (ECM) impeller is 95% energy
efficient providing “green” energy savings (See Appendix D). Because of
the high efficiency, the impeller runs extremely quiet for the comparative
amount of airflow volume. All Paramounts run at or below 62 dbA at 80 fpm
and most Paramounts run at or below 59 dbA at 80 fpm. By design, the ECM
impeller is located after the filters assuring an intrinsically safe design where
all contaminated air is filtered effectively. See Chapter 2: Prerequisites for
complete airflow exhaust volume, noise pressure, and face velocities of 60,
80 and 100 fpm. The ECM impeller has a programmable blower timer
should you desire additional “green” energy savings.
Audible/Visual Alarms
The audible/visual alarms remind the operator to check the filters with
sampling tubes or replace the filter. Filter replacement alarms occur in
audible/visual modes for both filter saturation activated by the Safety-First
Vapor Sensor or the final filter elapsed time. A low airflow alarm occurs
when the face velocity drops below programmed levels.
Large Control Panel LCD Display
The large (3" x 1.5") LCD message center provides continuous status reports
for each filter, displays airflow speed, and displays alarm messages for both
filters and airflow. The touchpad can be programmed for filter types, filter
check times, and filter replacement times. Audible/visual alert time messages
appear after the specified number of hours has elapsed. The audible/visual
alarm reminds the operator to check the filters with sampling tubes or replace
the filters. Filter replacement audible/visual alarms occur for both the SafetyFirst Vapor Sensor and final filter elapsed time.

Chapter 4: Performance Features and Safety Precautions
Ergonomic Sloped Front
The ergonomic slope provides maximum visibility and comfort, reduces
glare, thereby minimizing operator fatigue. The space saving design (U.S.
Patent No. D538,941) increases effective laboratory work space, because the
impeller and filters are all self-contained within the enclosure and a separate
filtered blower unit is not required.
Convenient Filter Replacement
The Paramount filter compartment was designed to make filter replacement
convenient and easy. The gas spring assisted clamping mechanism opens
effortlessly and applies uniform pressure across the entire top surface of the
filters for leak-proof, one-step filter replacement from the front of the
enclosure.
Durable Construction
Unlike comparable plastic or acrylic ductless fume hoods and enclosures, the
Paramount Ductless Enclosure is manufactured with durable tempered safety
glass and dry powder epoxy-coated aluminum and steel. The sides and sash
are made from tempered safety glass that will not easily discolor or craze like
plastic. The frame is made from dry powder epoxy-coated aluminum and
steel providing further strength and corrosion resistance to solvents and acids.
Fluorescent Light with Electronic Ballast
The fluorescent light is located above the work area, out of contact with
contaminated air and easy to service. All Paramounts have a fluorescent light
and energy saving light timer with electronic ballast. The light timer is a
programmable feature should you desire additional “green” energy savings.
Utility Iris Ports
All Paramounts have two utility iris ports that allow electrical cords and data
cords to pass through the back of the enclosure without leaving a large hole
for contaminants to escape. The enclosure ships with both solid plugs and
iris ports for your convenience.

Product Service 1-800-522-7658
Chapter 4: Performance Features and Safety Precautions
Maximum Visibility
Visibility is maximized on all units with at least 270 degree visibility from
both sides and the front pivoting sash. Some 3' and 4' models have 360
degree visibility which is especially useful in classroom demonstrations. See
Chapter 2: Prerequisites for model differences and model numbers.
Simple Electrical Connection
All 100-115V Paramounts are pre-wired with circuit breaker and IEC
electrical power cord that is simply plugged into a nearby electrical
receptacle. 230V units are shipped without a plug. Install the appropriate
plug for your electrical specification per local codes. All the impeller, light,
and airflow monitor wiring is internal and no electrical wiring connections
are needed. Paramounts are available in two voltages, 100-115V, 50/60 Hz
and 230V, 50/60 Hz. See Chapter 2: Prerequisites for model numbers.
Safety Precautions
1. Although the enclosure has been engineered to maintain optimum
operator safety, caution should always be used while working. Prior
to using the enclosure, check to make sure that the exhaust blower is
operating and that air is entering the enclosure at its specified face
velocity. The airflow monitor will alert the user to a problem with
airflow.
2. Use good housekeeping in the enclosure at all times. Clean up spills
immediately. Periodically clean enclosure interior.
3. Do not overload the work surface with apparatus or work material.
The safe operation of the enclosure is based upon having proper
airflow through the structure. Do not place large objects directly on
the work surface. Instead, elevate the object 3/4" on blocks to allow a
flow of air under the object and into the rear baffle exhaust slots.
Ensure blocks are level and secured in place.
4. Blocking large portions of the rear baffle will change the airflow
pattern in the enclosure causing turbulence. (Do not store containers
or supplies against the rear baffle, as this will affect airflow).
5. Always work with your hands as far back into the enclosure as
possible. Keep all powders, chemicals and apparatus inside the lower
air foil of the enclosure.
6. Do not work in this enclosure without the blower running and a face
velocity of 60-100 fpm.
7. Perchloric acid use in this enclosure is prohibited.
8. High-level radioisotope materials are prohibited in this enclosure.
Consult your Safety Officer.
Product Service 1-800-522-7658
21
Chapter 4: Performance Features and Safety Precautions
9. Avoid cross drafts and limit traffic in front of the enclosure. Air
disturbances created may draw contaminants out of the enclosure.
10. A qualified certification technician should test the enclosure before it
is initially used. The enclosure should be validated whenever it is
relocated.
11. The use of safety goggles, protective clothing, gloves and any other
personal protective equipment recommended by your safety officer
should be used.
12. The sash must remain in the down position while using the enclosure.
13. Proper performance of the enclosure depends largely upon its location
and the operator’s work habits. Consult the references in Appendix D.
14. The enclosure should be recertified whenever it is serviced or at least
annually thereafter.
15. Use of an open flame must be avoided in the Paramount. Open
flames may disrupt the airflow patterns in the cabinet and cause a fire
hazard with volatile chemicals and solvents.
16. Handle new and used filters with care during installation and removal.
Refer to Installation Instructions in this manual for proper handling of
filters.
17. Saturated carbon filters and HEPA filters are to be disposed of as
hazardous waste. The user is responsible for recording the chemicals
adsorbed or removed by the filters and disposing of them properly.
18. Use in areas where only trained users have access to the enclosure.
Any new users must be trained and should also read this User’s
Manual.
19. Do not use the Paramount in a poorly ventilated area. If the
Paramount is to be used in a confined space, make sure the space is
well ventilated and the concentration of toxic contaminants cannot
accumulate greater than the exposure limit/TWA.
20. The warning properties (i.e., odor, taste) of the volatile organic
compounds or other material being used in the enclosure must be
adequate to provide an early indication that the carbon filter may be
saturated. In other words, it is best when the odor threshold is less
than the exposure limit/TWA.
21. Highly toxic vapors, unknown reaction, hazardous particulate, or
processes generating high levels of contaminants are not intended for
use in the Paramount.
22. Labconco Filter labels are color coded to match NIOSH respirator
types. Only chemicals which can be safely adsorbed/treated with the
specific carbon based filters installed or removed by HEPA filters are
appropriate for use in this enclosure.
22
Product Service 1-800-522-7658
Chapter 4: Performance Features and Safety Precautions
23. Use the smallest possible quantity of chemical(s) within the enclosure
and never exceed the amount which can be effectively adsorbed by
the filters before breakthrough.
24. Leave the blower on for at least one minute after work in the
enclosure has been completed.
25. If a chemical is spilled on the work surface DO NOT switch off the
blower until all traces of the chemical has been removed.
26. Make sure filters are installed prior to each use. Remove the front
panel to install the filters.
27. If the blower fails during use, chemical processes should cease and
the area should be vacated and ventilated before servicing the blower.
28. Always refer to the Paramount Chemical Guide and/or the NIOSH
Pocket Guide to Chemical Hazards before proceeding. For additional
help with filter and chemical selection, contact Labconco at 800-8215525 or 816-333-8811.
29. The surface of the HEPA filter is fragile and should not be touched.
Care must be taken to avoid puncturing the HEPA filter during
installation or normal operation. If you suspect that a HEPA filter has
been damaged DO NOT use the enclosure; contact a local
certification agency or Labconco. Reference Chapter 6 for the HEPA
filter certification procedure.
30. The HEPA filter in the enclosure will gradually accumulate airborne
particulate matter from the room and from work performed in the
enclosure. The rate of accumulation will depend upon the cleanliness
of the room air, the amount of time the enclosure is operating and the
nature of work being done in the enclosure.
31. Ensure that the ductless enclosure is connected to an electrical service
in accordance with local and national electrical codes. Failure to do
so may create a fire or electrical hazard. Do not remove or service
any electrical components without first disconnecting the enclosure
from electrical service.
32. Tag the enclosure with appropriate warning, if any filters have been
removed for service.

Chapter 4: Performance Features and Safety Precautions
Misapplications that Could Result in a
Hazardous Situation
There is one scenario where the Paramount’s misapplication could be a part
of a hazardous condition. That situation is where;
1. the Inlet Concentration is greater than the exposure limit/TWA,
2. the filter becomes saturated,
3. the user continues to operate,
4. and the ventilation of the room is insufficient to dilute the exhaust of
the Paramount to below the exposure limit/TWA for the chemical.
Important Note: When the inlet concentration is greater than the exposure
limit/TWA, extra measures must be taken to monitor the number of air room
exchanges. A well designed room with proper air exchanges will properly
dilute the exhaust from the Paramount by a multiplier of 25%.

If a Check Airflow Activates
The most common causes of a check airflow alarm are:
• Blockage of the inlet perforated baffle or exhaust outlet.
• Loading or blockage of the filters resulting in low airflow.
• Motorized impeller failure or faulty electrical connector to the impeller.
Note: If the alarm sounds during use, immediately take appropriate action to
prevent contamination to you and other personnel in the area.
Resetting the Airflow Alert System
The Check Airflow Alarm automatically resets to normal operation and
displays the face velocity once the face velocity has increased and stabilized.
Working In the Paramount Ductless Enclosure
Planning
• Thoroughly understand procedures and equipment required before
beginning work.
• Arrange for minimal disruptions, such as room traffic or entry into the
room while the cabinet is in use.
Start-up
• Turn on blower and observe face velocity.
• Turn on the fluorescent light.
• Allow the enclosure to operate unobstructed for 1 minute.
• Wear a long sleeved lab coat with knit cuffs and over-the-cuff rubber
gloves. Use protective eyewear. Wear a protective mask if appropriate.
Loading Materials and Equipment
• Only load the materials required for the procedure. Do not overload
the enclosure.
• Do not obstruct the enclosure’s perforated baffle.
• Large objects should not be placed close together.
• Always operate with the sash in the closed position.

Product Service 1-800-522-7658
Chapter 5: Using The Ductless Enclosure
Work Techniques
• Keep all materials a minimum of 4 inches (100 mm) from the inside
of the lower air foil, and perform all contaminated operations as far to
the rear of the work area as possible.
• Segregate all clean and contaminated materials in the work area.
• Arrange materials to minimize the movement of contaminated
materials into clean areas.
• Keep all discarded contaminated material to the rear of the work area.
• Avoid moving materials or the operator's hands and arms through the
front access opening during use.
• Avoid the use of an open flame.
• Avoid using techniques or procedures that disrupt the airflow patterns
of the enclosure.
Final Purging
• Upon completion of work, the enclosure should be allowed to operate
for two to three minutes undisturbed, to purge airborne contaminants
from the work area.
Unloading Materials and Equipment
• Objects in contact with contaminated material should be surface
decontaminated before removal from the enclosure.
• All open trays or containers should be covered before being removed
from the enclosure.
Wipe-Down
• Wipe down the interior surfaces of the enclosure with suitable

Product Service 1-800-522-7658
Chapter 6: Maintaining the Ductless Enclosure
Quarterly (or more often as required)
• Note the airflow velocity on the display. Determine the actual airflow
face velocity through the sash opening of the enclosure where the
average reading should be at the specified velocity. (Use calibrated
thermal anemometer or other approved apparatus).
• The enclosure’s perforated baffle should be checked for any blockage
to ensure that the enclosure is maintaining proper airflow.
• Replace carbon filters when chemical breakthrough is indicated by
organic sensor, odor, time, detector tube, or for some chemicals,
analytical instrumentation. See “Install Carbon Filters” section of this
manual in Chapter 3.
• While the enclosure is filled with a contaminant, test filter condition
on carbon filters using the appropriate gas detector tube at intervals
of 20% of the total estimated time. The exception to the 20%
recommendation is formaldehyde or any carcinogen or suspected
carcinogen. These hazardous chemicals must be checked at a
minimum of every 10% of the total estimated time. Gas detector
tubes for the specific chemicals that are being used in the enclosure
can be obtained from your laboratory supply dealer.
• All weekly activities.
Annually
• Replace fluorescent lamps, if necessary.
• Replace HEPA filters if the face velocity drops below the
recommended speed for your facility as the airflow alarm alerts you.
• Have the enclosure validated by a qualified certification technician.
See Certification and Recertification in Chapter 6.
• All quarterly activities.
Determination of When to Replace Carbon Filters
The carbon filters MUST be replaced when any one of the following four
conditions are met:
1. The Safety-First Vapor Sensor indicates chemical breakthrough with an
audible alarm and the display reads “Replace Filters.”
2. The Filter Life timer has expired as programmed for typical usage.
3. Chemical odor in the work area is detectable, or the concentration of the
chemical in the work area is greater than the exposure limit/TWA.
4. Gas detector tubes change color when sampling the ductless enclosure
outlet (exhaust), indicating breakthrough.
Product Service 1-800-522-7658
39
Chapter 6: Maintaining the Ductless Enclosure
There are five means of determining when its time to change the carbon
filters (not shown in the order of preference).
Odor - A person’s sensitivity to odor, tolerance of odor and their comfort
level under odoriferous conditions vary with the individual. Odor is an
indicator that chemicals are passing through the carbon filter. Additionally,
several points need to be understood:
• Odor can be used as a prompt to sample the exhaust to confirm
breakthrough.
• Organic chemicals approved for use in the ductless hood usually have
odors that are detectable before reaching the time weighted exposure
limits.
Safety-First Vapor Sensor - The organic sensor detects filter saturation
from exhaust gas concentration to alert the operator to replace filters. The
electronic sensor will signal when the concentration is under 5 ppm for most
chemicals with a range of 0.1-30 ppm. The early warning provided by the
Safety-First Vapor Sensor provides the user ample time (5-10% remaining
filter life) to complete work in process before replacing the filters. The vapor
sensor includes a primary and backup sensor for redundant monitoring and
both sensors detect typical organic solvents, smoke particulates, ammonia
gases, formaldehyde gases, and hydrogen sulfide gases; the vapor sensor does
not detect mineral acid gases such as hydrochloric acid, nitric acid, or sulfuric
acid. Consult the table in Chapter 4 for a partial listing of tested chemicals in
order of sensitivity as the sensitivity differs for each chemical; most tested
chemicals have a sensitivity alert concentration below 5 ppm as provided in
the table in Chapter 4.
Safety Note: The use of the organic sensor is not recommended for the
determination of filter saturation when the exposure limit/TWA for the
chemical is under 5 ppm. Other detection methods must be implemented
unless testing is performed by the end user and the known exhaust
concentration is below the acceptable exposure limit/TWA.
Detection Tubes - Color change indicators can be used to measure the
concentration of the chemical at the exit side of the carbon filter, between
filters, or in the outlet exhaust. A kit including syringe pump and flexible
tubing can be purchased as an accessory from Labconco (Catalog #
6924900). Labconco Customer Service Representatives are supplied with
detector tube catalog numbers, as well as telephone numbers to direct you to
where to purchase these items.
For organic, mineral acid, formaldehyde and ammonia, chemical specific
detector tubes should be purchased when installing fresh filters. Each kit
contains instructions on how many strokes of the syringe are required to
obtain the stated sensitivity. The sampling syringe is connected to the
ductless enclosure exhaust. The hose from the sampling syringe inlet can be
40
Product Service 1-800-522-7658
Chapter 6: Maintaining the Ductless Enclosure
inserted between the stacked filters to sample the lower filter or inserted
through the holes in the blower exhaust cover to sample both filters. Connect
the syringe to the detector tube while the system is running and pull the air
through the tube with the syringe. Each stroke of the syringe represents a
100-ml sample and corresponds to the number of strokes necessary to give
the indicated color changes. Due to the wide variety of organics and varying
exposure limit/TWA’s, it is recommended that specific detector tubes be
purchased directly from Sensidyne, Dräger or your laboratory supply dealer.
Alternate detector pumps can also be purchased from your laboratory supply
dealers.
The vast majority of detector tubes available start measuring at the exposure
limit/TWA and the concentration value measured is not important. When a
user observes any color change in the tube, they should replace the filter
immediately. If no detector tube for your specific chemical is available, other
means of detection must be used.
Time - For applications that have very consistent inlet concentrations and
operating time, “Time” can be used to anticipate saturation or exposure
limit/TWA levels based on prior experience. However, this does not replace
the need for sampling. Consult Labconco Specialist for an estimate of carbon
filter life based on chemical usage. Refer to Chapter 3 on how to “Set the
Filter Life and Filter Check Timers.” Detector tubes, or analytical
instrumentation should always be used to determine concentrations in the
carbon filter. It is recommended that the carbon filters be checked with
detector tubes or other means at intervals of 20% of the total estimated filter
life. The exception to the 20% recommendation is formaldehyde and any
carcinogen or suspected carcinogen. These more hazardous chemicals must
be checked at least every 10% of the total estimated time.
Analytical Instrumentation - This is the most accurate means of measuring
concentrations of any chemical. It is the method of choice when no detector
tubes are available or the tubes are not sensitive enough to measure at the
exposure limit/TWA concentration for the chemical. This method is also to
be used to determine saturation when the chemical concentration is below the
measurement range of detector tubes. One relatively low cost method of
analytical instrumentation includes the use of a PID (photoionization
detector) that measures gas concentrations and is available from RAE
Systems or PID Analyzers, LLC.
Determination of When to Replace HEPA Filters
The HEPA filters in ductless enclosures gradually accumulate airborne
particulate matter and powders from the enclosure and room. The rate of
accumulation will depend upon the cleanliness of the room air, the amount of
time the enclosure is operating, and the nature of work being done in the
enclosure. Replace HEPA filters if the face velocity drops below the
recommended velocity. Replace HEPA filters if it fails the HEPA Filter Leak
Test in Chapter 6.

HEPA Filter Leak Test
Purpose
After installing the new HEPA filter, the HEPA filter can be leak checked.
This test is performed to determine the integrity of the HEPA filter, the filter
housing, and the filter mounting frames. Leak testing is to be done by a
qualified technician with calibrated equipment. Leak check testing is
performed as a downstream average above the perforated exhaust cover
above the motorized impeller. The filter passes the leak test at .01% or
better. Reference Leak Testing and Photometer scanning from the Institute
of Environmental Services (IES-RP-CC001.3)

Change the Airflow Face Velocity (If Necessary)
The Paramount has been tested and shipped at a face velocity of 75-80 fpm.
If necessary, refer to the instructions in Chapter 3 to change the face velocity.
Refer to the “Calibration” menus in Chapter 5 that refer to the “Pressure
Sensor” and “Airflow Alarm.” The “Calibration” menus require a password
to protect the ductless enclosure integrity and the password can only be
obtained from Labconco Product Service for certifier use. The “Airflow
Alarm” should be set at 10-20 fpm below the normal operating face velocity
and it was tested and shipped at 60 fpm.
Initial Certification
The ductless enclosure has been certified at the factory for an inflow velocity
of 75-80 fpm. The ductless enclosure should be certified for the proper
inflow velocity required by your Safety Officer. Transport, altitude, or
temperature differences may require the “Calibration” of the “Pressure
Sensor” to be reset as outlined in Chapter 5: Using the Ductless Enclosure.
If a HEPA filter is used, it is a conservative recommendation to perform the
HEPA Filter Leak Test should there be any damage to the media caused
during transport.
Re-Certification
Under normal operating conditions, the enclosure should be recertified at
least annually if serviced. The certifier should perform the following tests.
• Airflow Velocity Test. If necessary, reset the Airflow Face Velocity and
Motor Speed per the “Calibration” of the “Pressure Sensor” menu listed
in Chapter 5.
• HEPA Filter Leak Test, if installed.
In addition, the following test should also be performed at the user’s
discretion:
• Smoke Test to determine proper airflow patterns.

The following examples are useful for estimating filter life so the Filter Life
Timers can be set properly.
Organic Vapor Carbon Filter Life
Consult the separate Paramount Chemical Guide and/or Labconco Specialist
to determine the filter capacity for your chemical. For example, assume you
are working with 10 ppm acetone in a 3' Paramount loaded with the required
four filters. Acetone has a specific gravity SPGR = 0.79 with a molecular
weight MW = 58.1. A 3' Paramount at 80 fpm uses 175 CFM or 4956 LPM.
The evaporation rate in ml/min can be solved by the following equation:
PPM = (SPGR/MW) * (24400000/Airflow (LPM)) * Evap. Rate (ml/min).
For 10 ppm acetone or 90 ml lost per week during 2 hours use per day, the
equations are solved below:
There are 30 pounds of activated carbon in a 3' Paramount which equals
13,500 g. Thus, the carbon Filter Life Time is calculated for acetone with a
2% filter capacity at (13,500 g/0.12 g/min) / (1 hour/60 min) * 2% capacity =
38 hours. The Final Life Timer should be set for 40 hours, rounded up from
38 hours. The Check Life Timer should be set for 20-25% intervals or every
10 hours and the carbon filters can be validated every 10 hours to verify safe
filter use.
Other chemicals such as ethyl acetate at 9% filter capacity and toluene at
20% filter capacity have much longer filter lives. For example, ethyl acetate
at 10 ppm used in the 3' Paramount will have a Filter Life of 120 hours.
Furthermore, toluene at 10 ppm used in the 3' Paramount will have a Filter
Life of 240 hours. These three chemicals are summarized in the table that
follows to show the Filter Life ranges and you should consult the Labconco
Specialist and/or Paramount Chemical Guide for further information on other
chemicals.

• 10 = (0.79/58.1) * (24400000/4956) * Evap. Rate (ml/min)
• Evap. Rate = 0.15 ml/min = 90 ml/week * 1 week /10 hours use *
10 hours/600 minutes
• Evap. Rate in (g/min) = 0.15 ml/min * 0.79 g/ml = 0.12 g/min

If the inlet concentration is decreased to 1 ppm, then the estimated filter life
will be increased by an average factor of 5. Likewise, if the inlet
concentration is increased to 25 ppm, then the estimated filter life will be
decreased by an average factor of 2. Experience with routine use will
establish a predictable filter life that is representative of your specific
chemical work.
Impregnated Carbon Filter Life
To estimate impregnated carbon filter life for acids, formaldehyde-formalin,
and ammonia, use the following chart below. The values in the chart below
are expressed in weight (grams) and volume (milliliters) which can be used to
estimate Filter Life from a known usage.
For example, you estimate that 37% hydrochloric acid is being used at 500
ml per week and want to know how to program the Filter Life timer for a 3'
Paramount. A 3' Paramount uses 40 pounds of impregnated carbon at 17%
estimated life before saturation. 17% of 40 pounds is equivalent to 3060
grams of available carbon. There are 424 g/L of hydrochloric acid in a 37%
solution. Thus, there are 3060 grams/424 g per L or 7.2 Liters (7200 ml) of
hydrochloric acid before saturation. Assuming there are 10 hours of use per
week at 500 ml per week, the expected Final Life is programmed at 140
hours and the Check Life is programmed at 40 hours and it comes from the
following calculation:
(7200 ml/500 ml/week) * 10 hours/week = 144 hours, rounded to 140 hours

Ductless enclosures require filtration efficiency testing to validate performance.
Independent testing, conducted by a consultant and the University of Kansas,
concluded the tested filtration efficiency for acetone, ethanol, isopropyl alcohol,
toluene and hydrochloric acid was excellent. Filtration capacity is defined as a
percentage of the chemical mass adsorbed compared to the total carbon filter weight.
Utilizing analytical instrumentation, the organic vapor filter and acid vapor filter were
both independently tested for filtration efficiency. The solvents and acids listed below
were evaporated at both low and high evaporation rates. Low evaporation rates are
typical in ductless enclosures in order to maximize useful carbon filter life. Both
ethanol and acetone were specifically tested at low evaporation rates of 14ppm and
22ppm, respectively, to simulate real laboratory conditions of chemicals with low
filter capacities. High evaporation rates of 100-462ppm were used for most of the
organic solvents and mineral acid to accelerate the testing process of chemicals with
higher filtration capacity and determine filter saturation and chemical breakthrough.
The testing was designed to assess the filtration efficiency of the filters. As suggested
by carbon manufacturers, carbon filters usually have a 30 percent to 40 percent
filtration capacity of theoretical values for organic chemicals with higher carbon
affinity. The test results show a filtration efficiency of 33-39 percent for chemicals
with higher affinity for organic vapor carbon and directly in line with the 30-40
percent as suggested by carbon manufacturers. Since ethanol has very low filter
capacity, it is not alarming that the filtration efficiency is 17-19 percent; the test
results prove the practical matter of using low quantities of ethanol or any other
chemical with very lower filter capacity. The mineral acid filtration efficiency of
hydrochloric acid approached 83 percent of theoretical value and is attributed to the
chemisorption process of the treated acid filters. To conclude, the filtration efficiency
test data and charts indicate the ductless enclosure filtration was in line with carbon
manufacturer expectations and will provide a safe working environment for
controlled environments.
