The purpose of calibration is to ensure the accuracy of the airflow display and alarm (if present). This involves
measuring airflow with reference instrumentation and establishing reference between airflow sensor(s) on the
enclosureto the standard reference. alibration should only be carried out by trained personnel. This section
presents a brief overview of the calibration menu function. For more information, refer to test report.

Chapter 3 – Basic Enclosure Operation
3.1 Starting and Shutting Down the Enclosure
3.1.1 Turning on the Enclosure
1. Turn on the fan by pressing the FAN button. Input the Fan PIN if asked (if PIN ≠ 0000). This will start
the warm up procedure (default: 3 minutes). All buttons are diabled during warm up period.
2. The enclosureis ready for work.
3.1.2 Turning off the Enclosure
1. Turn off the fan by pressing the FAN button. Input the Fan PIN if asked (if PIN ≠ 0000). This will start
the post purge procedure (default: 0 minute). All buttons are disabled during post purge period.
3.2 Working in the Enclosure
•Surface-decontaminate the work area before and after using the enclosure.
•Allow the enclosureto purge any contaminant by allowing the blower to operate at least 3 minutes
before and after using the enclosure.
•Minimize room activity (personnel movements, closing and opening of doors, etc.) since these
external airflow disturbances may adversely affect the enclosure’sinternal airflow, thereby possibly
impairing the containment capabilities of the enclosure.
•While working in the enclosure, move your hands slowly and in a controlled manner.
•PW1 uses alarms to indicate that the condition inside the enclosure is not safe for the operator, so
check the L D display to understand the cause of these alarms.
3.3 Stopwatch and Experiment Timer
•The stopwatch function can be started by pressing the UP button while the sash is closed. Pressing UP
button again while the stopwatch function will stop and resume the timer. Pressing DOWN button will
leave the stopwatch function and reset the timer. The timer in the stopwatch function is counting up
and shown using the HH:MM:SS format.
•The experiment timer can be started by pressing the DOWN button while the sash is closed. Pressing
DOWN button while the experiment timer function is working will stop and resume the timer.
Pressing the UP button will leave the experiment timer function and reset the timer. The timer in the
experiment timer function is counting down and shown using the HH:MM:SS format. Operator can
use the SETTINGS | EXP TIMER menu (refer to section 2.2.1.4) to set the experiment timer.
3.3 Working Ergonomics
On most occasions, you would most likely be operating the enclosurein sitting rather than standing posture.
There are some obvious advantages of the sitting posture:
•The physiological energy cost and fatigue involved in sitting are relatively less
•Sitting posture provides the body with a stable support
However, sitting position has some drawbacks too:
•The working area available is fairly limited
•There is a potential risk of being constrained in the same posture for a long time
•Sitting posture is one of the most stressful postures for one’s back

8
Therefore you should pay careful attention to the following guidelines in order to achieve comfortable and
healthy working conditions:
•Always ensure that your legs have enough legroom.
•Keep your lower back comfortably supported by your chair. Adjust the chair or use a pillow behind
your back whenever necessary.
•You should place your feet flat on the floor or on a footrest. Don’t dangle your feet and compress
your thighs.
•You should keep varying your sitting position throughout the day at regular intervals so that you are
never in the same posture for too long.
•Observe the following precautions with respect to your eyes:
oGive your eyes frequent breaks. Periodically look away from the work area and focus at a
distant point.
oKeep your glasses clean.
•Arrange the items/apparatus frequently used in your work in such a way that you can minimize the
physical strain involved in handling them.
•Exercise regularly
The enclosure’snoise emission has been tested and found to be in compliance with EN 12469, ISO 4871 and
NSF/ANSI 49 which is important to ensure health and comfort for the operator.
Ergonomics accessories available with Esco include:
•Armrest padding
•Lab chair
•Footrest
Please contact your local distributor or Esco for more information.
