Three service valve access ports are located on each side panel. When
installing service valves, remove the center of the port plugs at the
perforations.
The optional stand may be ordered in two configurations; a manually
adjustable from 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:

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 personnel 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,
allowing 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).

1300 Series A2 1-3Thermo Scientific
Section 1
Description
HEPA filters
The downflow air within the chamber and the exhaust air are cleaned by
HEPA filters.
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
should remain closed. The closed window blocks out the UV rays.
Opening the window will cause the UV light to turn off.
Digital Airflow Verification (DAVe)
Independent monitoring of inflow and downflow air velocities
guarantees that product and personnel protection remain
uncompromised. Airflow monitoring determines the velocity of the
airflow in the sample chamber as well as the inflow velocity of air
through the exhaust opening. 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.
SmartFlow Indicator
The SmartFlow Indicator provides assurance that the inflow is balanced
properly. SmartFlow monitors the advanced motor technology adjusting
airflows even as the filter resistances change due to loading or other
influences. The SmartFlow Indicator visually demonstrates the cabinet’s
ability to compensate to maintain personnel protection. Green indicators
show the fan and filters have power and capacity in reserve to respond to
additional demands. Yellow or red indicators show that while the cabinet
is providing personnel and product protection, maintenance should be
scheduled to restore the compensation reserve.
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.

The sample chamber is accessible through various positions of the front
window. The working position of the window is a 8 or 10 inch opening,
+0.25”, -0.75” (depending on model - check data label and first page of
this manual). For loading the chamber, the window opens fully. For
decontamination and energy saving, enter into Night-Set-Back mode by
closing the window. When the window is closed, the blower speed is
reduced, minimizing energy consumption and noise emittance without
compromising particulate containment inside the work chamber.
Note The working and loading window positions are indicated on the user
interface, as controlled by micro switches and displayed by status
indicators on the control panel. s

To place the window at the work position, move it to the area of the top
‘dimple’ (Figure 1-5) and watch for the GREEN sash position height
indicator to illuminate (Figure 1-6). If the window is moved from the the
work position, the sash height indicator will turn RED.
To place the window in the closed or reduced mode position, move it to
the area of the lower ‘dimple’ (Figure 1-7) and watch for the BLUE
reduced mode indicator to illuminate (Figure1-8). If the window is not
positioned correctly, or is moved from the closed position, the BLUE
indicator will be extinguished. When the BLUE reduced mode indicator
is not illuminated, the unit will not operate in reduced mode, and the
optional UV light will not function.

Description
The optional, factory-
installed UV light is
installed at the top of the
front section of the sample
chamber.
The operating time of the
UV light is preset for 1
hour. The UV disinfection
procedure can be started by
pressing the “UV” key on
the control panel with the
window in the closed
position. If the window is
opened, the procedure is
immediately cancelled.
Note To protect from UV radiation, the UV light can only be turned on
when the window is completely closed. s
The single piece work tray is provided with the cabinet. It is placed onto
the frame above the sample chamber drain pan. It can be removed by
lifting up, using the large holes in the work tray.
The working area for optimal product protection extends over the entire
width and depth of the work tray. The two optional armrests are
positioned in the center of the working area 8 inches (20 cm) from each
other. To attach the armrests, insert into the first perforated track of the
work tray.
Warning Work safety is assured only if the armrests are used correctly! s

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. (2000 m) above sea level.
• Power outlet accessible to authorized personnel only. Ideally, the outlet
should be installed above the biological 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 (200 mm).
• Equipped with an appropriate ventilation system.
• Room temperature between 10° and 40° (50°F and 104°F).
• Relative humidity must not exceed 80%, up to 31° and decreasing
linearly to 50% at 40° .
• 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 biological 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 (7.6 cm), unless upper wall brackets are used.

The part numbers for the optional thimble exhaust connection are
1911316 for three, four & five foot units, and 1911317 for six foot units.
The test conditions according to NSF/ANSI 49 were performed with the
standard version of the safety cabinet, without exhaust system accessories.
An available accessory for the biological safety cabinet exhaust system is an
exhaust thimble connection for an on-site exhaust system with blower.
According to NSF/ANSI Standard 49, an exhaust alarm is required with
this connection.
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 3, 4 and 5 ft. models:
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. Secure the accessory by tightening
the supplied retaining screws
(M5) wrench-tight.
4. Using the adjustment nuts on the
sliding panel, set the gap height
to an opening of 2 inches.
