Safety Systems
The optional stand may be ordered in three configurations; a fixed 30”
working height, a manually adjustable 30” to 38” working height, and a
fixed 34” working height with attached casters.
A stainless steel one-piece work surface is standard. Optional armrests
ensure a comfortable working position for the user and minimize
blockage of airflow at the front grille.
Internal outlets, provided as the power source for accessories, are provided
standard in the following configuration:
1354, 1355, 1359, 1385: one duplex right side
1357, 1387: two duplex left and right side
1356, 1384, 1386: one single right side
1358, 1388, 1389: two single right and left side
Test hoses (aerosol challenge ports) are located under the work tray. The
supply plenum hose is located on the left and the exhaust plenum hose on
the right.
Note Do not remove the caps of the two test hoses to check for supply
and exhaust airflow. s
Negative pressure air system
A negative pressure air system combines with HEPA filters in the supply
and exhaust airflow for personal and product protection.
Personnel protection
Inflow air along the entire working opening at a constant high velocity
prevents leakage from the work opening of the chamber.
Exterior air pressure being higher than the internal air pressure creates
negative pressure, ensuring containment in case of cabinet leakage.
Product protection
Steady airflow within the air system ensures constant downflow, allow-
ing the HEPA filters to remove contaminants so that the samples are
always surrounded by ultra-pure air. Harmful particles are not carried
over the sample chamber (protection from cross-contamination).
HEPA filters
The downflow air within the chamber and the exhaust air are cleaned
by HEPA filters.

1300 Series A2 1-3Thermo Scientific
Section 1
Description
Safety lockout
To protect from UV radiation, the optional UV light will not turn on if
the front window is open. While the UV light is on, the front window is
closed and locked. The closed window blocks out the UV rays.
Airflow monitoring
Airflow monitoring determines the velocity of the airflow in the sample
chamber as well as the inflow velocity of air through the exhaust open-
ing. As soon as airflow velocities rise above or fall below a specified safety
value, an audible and a visual alarm is activated.
Window position monitoring
The position sensors detect the size of the front window opening and
indicate whether the window is open to the specified work position,
closed (energy saving) or in an unsafe intermediate position.
Thermo Performance Factor
The Thermo Performance Factor (PER) is a value that indicates the safe-
ty status of the cabinet. This value is calculated from data determined by
HEPA filter loading, airflow status and values captured during certifica-
tion. This data is entered into a parameter list of the control software
and interconnected. The result is indicated on the display by LEDs.
On certification by qualified personnel with a new HEPA filter, the per-
formance factor of the unit is indicated by green-green LEDs. As the
unit ages with use, the colors change. Red-red is unacceptable and the
unit should not be used. Any questions as to the safety of the unit
should be resolved before use.
Safety Systems
(continued)

The filter system consists of two HEPA filters for downflow (supply) and
exhaust air.
Room air is drawn into the sample chamber through the work position
window opening. The room air is drawn into the negative pressure drain
pan air duct, then
pulled into the air
plenum in the top
portion of the cabinet.
The room air is mixed
with recirculating
HEPA filtered air from
the chamber, and
filtered proportionally
by the downflow and
exhaust filters. The
filtered air is then
supplied as ultra-pure
air into the sample
chamber of the unit,
and exhausted as ultra-
pure air into the room
environment, or into
an external exhaust
system via an exhaust
transition.
Sectional paper catch grids are installed beneath the work tray in the air
duct between the inner and outer back wall of the unit. These grids
prevent large items such as paper towels and tissues from entering the
plenum where they may impair the function of the blowers or the filters.
The grids can be easily removed for cleaning.

Section 2 Installation
The operational safety and proper function of the unit depend on the
location where it is to be operated. The cabinet should be operated only in
the ambient conditions listed below.
• Up to 6562 ft. (2000m) above sea level.
• Power outlet accessible to authorized personnel only. Ideally, the outlet
should be installed above the bio-safety cabinet. The power cord is the
mains disconnect.
• Location capable of supporting the weight of the device and non-
flammable.
• If the factory-approved stand is not purchased, the holding device must
be rated for twice the cabinet weight.
• Adequate room height. For devices that are not connected to an
exhaust system, the distance between the exhaust air opening at the
device and the room ceiling must be at least 8 inches (200mm).
• Equipped with an appropriate ventilation system.
• Room temperature between 10°C and 40°C (50°F and 104°F).
• Relative humidity must not exceed 80%, up to 31°C and decreasing
linearly to 50% at 40°C.
• For indoor use only.
Room ventilation should preferably be a ventilation system that complies
with the national requirements for the application.
The inlet air and exhaust air openings of the room ventilation must be
located so that drafts do not impair the function of the bio-safety cabinet
air system.
When positioning the cabinet, make sure the counterweight on the back of
the unit can move freely. The minimal distance to the wall or adjacent
objects should be 3 inches (7.6cm)

The part numbers for the optional thimble exhaust connection are
1911316 for four foot, and 1911317 for six foot units.
The test conditions according to NSF 49/2004 were performed with the
standard version of the safety cabinet, without exhaust system accessories.
An available accessory for the bio-safety cabinet exhaust system is an
exhaust thimble connection for the connection to an on-site exhaust
system with blower.
The exhaust system components are installed to the exhaust opening on
top of the cabinet. The threaded inserts for the retaining screws are pre-
installed in the unit.
Installation on a 4 ft. model:
1. Turn the unit off and disconnect it from the power source.
2. Thoroughly clean the surfaces
around the exhaust opening and
of the accessory to be installed, to
ensure that they are free of debris.
3. Apply sealant onto the contact
surfaces.
4. Secure the accessory by tightening
the supplied retaining screws (M
