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

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.

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.
