OPERATOR'S MANUAL BIOPROtect II JR Vent to ... - Baker Company

III - PROPER CABINET USE
The BIOPROtect II Jr. is designed for continuous operation. The Baker Company recommends
continuous operation to keep the interior work space clean and free of unwanted particles. If the blower is
not running, the workspace of the cabinet will become contaminated with room air. If the cabinet’s use is not
understood or the cabinet is operated incorrectly, it will not provide an adequate protective barrier.
It would be helpful for operators to learn about the capabilities and limitations of the cabinet by reading
some of the available literature. The Eagleson Institute offers several videotapes and an interactive CD which
illustrate proper operation techniques for biological safety cabinets.
A biological safety cabinet is a valuable supplement to good sterile technique, but is not a replacement for
it. All activities that are to be performed in your cabinet should first be approved by a competent
professional, such as an industrial hygienist or safety officer. This will ensure the cabinet is appropriate for
the work it will be required to do. A competent professional should monitor the cabinet and its operating
personnel at regular intervals to see that it is being used correctly.
Operator Controls:
The operator controls and indicators are arranged on the front panel of the unit.
Blower On / Off Switch –
This push button is a maintained action switch that controls the power to the cabinet blower. Pressing
and releasing the push button from the UP/OFF position will change the switch to the DOWN/ON
position. The cabinet blower will start. The GREEN indicator in the push button will illuminate. Pressing
and releasing the push button from the DOWN/ON position will change the switch to the UP/OFF
position.
Caution: The cabinet audible alarm is disabled when the Blower switch is in the OFF position
Light On / Off Switch –
This pushbutton is a maintained action switch that controls the power to the cabinet fluorescent lights.
Pressing and releasing the pushbutton from the UP/OFF position will change the switch to the
DOWN/ON position. The cabinet lights will illuminate. The GREEN indicator in the pushbutton will
illuminate. Pressing and releasing the pushbutton from the DOWN/ON position will change the switch to
the UP/OFF position.
Mute switch -
This pushbutton is a momentary action switch that temporarily mutes the audible alarm. A timer
module inside the canopy controls the length of time that the alarm is muted. This is set at 5 minutes as a
factory default but can be changed to 1 second to 100 hours. It may be desirable to increase this setting
when cabinet decontamination is being performed. The YELLOW indicator in the pushbutton will
illuminate while the alarm mute function is active. Should the alarm condition be remedied before the
mute ‘times-out’ the timer will be reset and the mute indicator will not be illuminated.
Left Side & Right Side Outlet On / Off –
A separate 10 amp breaker switch is supplied for the remote switching of power to the right and left
outlet receptacle located inside the BIOPROtect II JR. The breaker switches will ‘trip’ if the total
electrical load on the circuit exceeds 10 amps.
