2. Prerequisites

Exhaust Requirements

Before deciding on a location, examine it carefully to ensure that it is compatible

with the cabinet’s exhaust duct. The area directly above the cabinet’s exhaust

port should be clear of structural elements, water and utility lines, or other fixed

obstructions. There should be enough clearance to allow for the passage of a

10" PVC or stainless steel duct. Avoid cabinet locations that require either an

elbow directly on top of the cabinet’s exhaust connection or an excessive

number of elbows to clear other items. For a further discussion of the cabinet’s

exhaust system requirements, please go to Chapter 3: Getting Started.

Electrical Requirements

The different Biosafety Cabinet models have the following electrical

requirements:

Model # Requirements

1310, 1311 115 VAC, 60 Hz, 12 Amps

1315, 1316, 1317, 1318 230 VAC, 50/60 Hz, 6 Amps

1360, 1361 115 VAC, 60 Hz, 12 Amps

1362, 1363, 1364, 1365 230 VAC, 50/60 Hz, 6 Amps

Note: A dedicated outlet with a circuit breaker should be located as close

as possible to the right rear side of the cabinet, at a height even with, or

higher than, the top of the bench or stand.

Table 2-1

Operating Instructions Safety Cabinet | 1300 Series B2

2. Prerequisites

Service Line Requirements

All utility service lines should be ¼ inch O.D., brass, copper, or stainless steel,

and equipped with an easily accessible shut-off valve. If the service line

pressure exceeds 100 PSI, it must be equipped with a pressure regulator to

reduce the line pressure. Consult local regulations for materials, pressures and

techniques regarding gas services.

Note: The use of flammable gases or solvents should be avoided in the

Biosafety Cabinet. Open flame in the cabinet will disrupt the laminar airflow in

the cabinet and may damage the HEPA filters. Flammable gases or solvents

may reach explosive concentrations in the cabinet or ductwork. If you feel that

the procedure requires the use of an open flame or flammable materials, contact

the institution’s safety office.

The use of air or gases under high pressure should be avoided as they may

seriously disrupt the airflow patterns in the cabinet.

3. Getting Started

Unpacking the Biosafety Cabinet

Carefully remove the outer carton and inspect the cabinet for damage that may

have occurred in transit. If the Biosafety Cabinet is damaged, notify the delivery

carrier immediately and retain the entire shipment intact for inspection by the

carrier.

Note: United States Interstate Commerce Commission rules require that claims

be filed with the delivery carrier within fifteen (15) days of delivery.

Do not return goods without the prior authorization of Thermo Fisher Scientific.

Unauthorized returns will not be accepted.

If the cabinet was damaged in transit, you must file a claim directly with the

freight carrier. Thermo Fisher Scientific is not responsible for shipping

damages.

Do not discard the carton or packing material for the Biosafety Cabinet until all

of the components have been checked, installed and tested.

The cabinet is secured to the pallet in two places on each side. To access the

nuts and bolts, remove the side panels by removing and keeping the two Phillips

screws on both panels. Swing the front of each panel away from the Cabinet,

and lift it straight up to remove the panel from the cabinet.

Moving the Cabinet

Move the cabinet, attached to its pallet, by using a floor jack, or a furniture dolly

underneath the unit. DO NOT move the cabinet by tilting it onto a hand truck.

Preparing the Biosafety Cabinet for Operation

Installation instructions for the cabinet are attached to the sash of the Biosafety

Cabinet. If these instructions are missing or unclear, contact Product Service at

1-888-213-1790.

Installing the Biosafety Cabinet on an Existing Work

Surface

Note: The Biosafety Cabinet is very top heavy. Use caution when lifting or

moving it.

When installing the Biosafety Cabinet onto an existing work surface or

benchtop, ensure that the structure can safely support the combined weight of

the cabinet and any related equipment. The work surface should be at least as

wide as the Cabinet and 31 inches (787 mm) deep to properly support the unit.

A hole or notch may be cut in the supporting surface in the right front corner to

accommodate the drain valve.

3. Getting Started

Installing the Biosafety Cabinet on a Base Stand

Thermo Scientific offers accessory Base Stands that effectively support the

weight of the cabinet. Stands for a B2 cabinet generally are not mobile, since it

is connected to an exhaust duct.

Telescoping Base Stands

Adjust the leg height before installing the cabinet on top of the stand. The height

can be set in 1-inch intervals between 27.5 to 34.5 inches (699 to 876 mm),

providing a Cabinet work surface height from 30.0 to 37.0 inches (762 to

940 mm). The Base Stands for each width Cabinet are listed in Table 3-1

below.

3. Getting Started

3. CAUTION: Only lift and support the cabinet at the stainless steel sides and

back. Damage will occur if lifted or supported on the front edge. Move the

base stand into its final location. Using a carpenter’s level, adjust each

leveling foot until the stand is level in both planes as shown in Figure 3-2.

You are now ready to lift the Biosafety Cabinet onto its stand.

Connecting the Biosafety Cabinet to Utility Service

Lines

The service lines (if any) should be connected to the tube fitting(s) on the

outside of the liner wall as shown in Figure 3-3. To install the tubing, follow

these steps:

1. Ensure that the tubing is ¼ inch O.D., soft metal, and that the end has been

completely deburred.

2. Route the tubing from the rear of the cabinet, ensuring that it will line up

with the slot in the back of the side panel. The slot is located from 8.75 to

11.25 inches (222 to 288 mm) from the bottom of the cabinet.

Note: Make sure that the tube routing will not contact any electrical wires. DO

NOT loop service line tubing within the side panels of the Cabinet.

3. Make sure that the nut on the tube fitting is loose, but do not remove it.

Look inside the fitting to make sure the tube ferrule is there.

4. Push the tube into the fitting until it is properly seated. The tube will go

approximately ¾ inch (19 mm) into the fitting.

Exhaust System Connections

The Total Exhaust Biosafety Cabinets are a “Type B2 cabinet,” meaning they

direct their HEPA filtered exhaust air out of the laboratory.

Note: The B2 Biosafety Cabinet is designed to be connected to an

appropriate exhaust system. Do not attempt to operate it when it is not

connected to an appropriate exhaust system.

THE EXHAUST CONNECTION IS A SEALED EXHAUST SYSTEM FROM THE

TOP OF THE CABINET TO THE REMOTE BLOWER. THE EXHAUST

SYSTEMS SHOULD BE DEDICATED TO A SINGLE CABINET. THE CABINET

IS EQUIPPED WITH AN EXHAUST FLOW ALARM, SUCH THAT AN ALARM

SOUNDS, AND THE CABINET BLOWER SHUTS OFF IN THE EVENT OF

INSUFFICIENT EXHAUST FLOW.

If your research involves the use of toxic compounds or volatile materials,

contact your facility’s safety officer or Thermo Fisher Scientific to ensure that

your cabinet and its exhaust system are compatible with the materials you will

be working with.

Figure 3-3

Operating Instructions Safety Cabinet | 1300 Series B2

3. Getting Started

Exhaust System Requirements

The cabinet exhaust stack is sized to accept 10-inch (254 mm) stainless steel

ductwork. The exhaust system’s blower should be sized to handle the sum of:

1) The pressure loss for the building’s exhaust system (duct work) when it

operates at the Cabinet’s flow rate.

2) PLUS The initial operating loss of the cabinet (1.0 inches (25 mm) of

water for the 1310 through 1318 Series B2 cabinets, OR 1.4 inches (36

mm) of water for the 1360 through 1365 Series B2 cabinets.

3) PLUS, In order to get the maximum possible life out of the cabinet’s

exhaust filter, the system should be able to draw an additional 2.0

inches (51 mm) of vacuum.

EXAMPLE

A 1310 Series Cabinet is being connected to an exhaust system that has a

calculated loss 0.5 inches of water when operating at the Cabinet’s required flow

rate of 810 CFM. What should the design capacity of the system be?

ANSWER 0.5” Exhaust system loss

+ 1.0” Initial Cabinet loss

+ 2.0” Reserve for maximum exhaust filter life

= 3.5” Vacuum total at maximum load

NOTE: The exhaust system should be fitted with a backdraft damper (part

#3858800) to prevent the reversing of airflow in the system.

Drain Valve Installation

In order to prevent damage during shipping, the drain valve assembly has not

been installed. It is not required, but if desired, the valve should be installed

after the Cabinet is in its final location.

To install the valve assembly, follow these steps:

Note: The work surface is heavy. Use caution when handling it.

1. Lift the work surface out of the Biosafety Cabinet by lifting on the knobs at

the front of the work surface. Steady the work surface while pulling it

straight out the front of the cabinet.

2. Using a putty knife, remove and discard the stainless steel cover that is

sealed over the drain mounting holes. Scrape out remaining sealant that is

around the holes.

3. Apply a light coating of silicone sealant (user supplied) to the mounting

surface of the drain assembly. Attach the drain assembly under the bottom

of the cabinet as shown in Figure 3-4. Wipe off any excess sealant from the

cabinet bottom. Ensure that the center drain hole is unobstructed.

4. Make sure the drain valve is in the closed position.

5. Reinstall the work surface.

6. Allow the silicone sealant to cure for at least eight hours before exposing it

to liquid.

Operating Instructions Safety Cabinet | 1300 Series B2

3. Getting Started

NOTE: If desired, the drain

valve assembly attaches to the

underside of the cabinet

bottom.

Apply a light coat of silicone

sealant to this surface of the

connector, aligning the three

holes in the connector with the

three holes in the Biosafety

Cabinet liner.

Initial Certification

Prior to use, a qualified certifier should certify all Biosafety Cabinets. Under

normal operating conditions, the Biosafety Cabinet should be recertified at least

annually and when relocated or serviced. The certifier should perform the

following tests, as recommended in ANSI/NSF International Standard Number

49 in effect when the cabinet was manufactured:

• Downflow Velocity Profile Test

• Inflow Velocity Test

• Airflow Smoke Patterns

• HEPA Filter Leak Test

Figure 3-4

3. Getting Started

• Site Installation Assessment Tests

• Vibration Test *

• Noise Level Test *

• Lighting Intensity Test *

*These tests are user comfort related tests and may be omitted at the

user’s or certifier’s discretion.

If you have any questions regarding certification agencies or need assistance in

locating one, contact Thermo Scientific at 1-888-213-1790.

NOTE!

4. Performance Features and Safety Precautions

All 1300 Series B2 Biosafety Cabinets operate using the following principles:

• Filtration and retention of particulates by High Efficiency Particulate Air

(HEPA) filter(s)

• Laminar airflow

• Directional airflow

The major components in a Biosafety Cabinet are:

• The HEPA or optional ULPA filter(s)

• The motor/blower to force air through the Cabinet

• Cabinet air intakes (grilles), ductwork and air balance controls

HEPA Filters

HEPA filters are disposable, dry-type particulate filters. The filter material or

media is typically made of borosilicate microfibers formed into a thin sheet, in a

process similar to the production of paper. This sheet is folded, or pleated to

increase its surface area. The pleats are held in place by aluminum diffusers or

by beads of glue that add rigidity to the media pack. The pack is then set into a

frame, and sealed as shown in Figure 4-1.

The HEPA filter manufacturer establishes the efficiency of the filter by

challenging it with an aerosol of known particle size. The number of particles

that penetrate the filter are quantified, and this establishes the efficiency of the

filter. Thus, the filters used in the Thermo Scientific 1300 Series B2 Cabinets are

at least 99.99% efficient in removing particles 0.3 micron.

Note: The HEPA filter media is very fragile. DO NOT touch the media. If you

think the media of a HEPA filter is damaged, DO NOT USE THE CABINET.

Have the HEPA filter integrity tested by a certifier before using the cabinet.

Note: HEPA Filters are only effective against particulate material. Gases will

pass through the filter.

ULPA Filters

ULPA filters have the same properties as the HEPA filters described above

except ULPA filters are rated at 99.999% efficient in removing particles 0.1-0.2

or 0.2-0.3 micron.
