Setting the Filter Life Gauge
During initial or annual certification of the biosafety cabinet, and after the HEPA filters
are changed, the Filter Life Gauge may need to be reset. There are three options to
choose from when resetting the Filter Life Gauge. Below are the three options, and an
explanation on which to select.
1.
New Filter
– Select this option when the HEPA filters are new. This occurs
during initial certification of a new biosafety cabinet, or after new HEPA filters are
installed and the biosafety cabinet’s Inflow and Downflow have been verified by a
trained and qualified certifier.
2.
Same Filter
– Select this option when passing through this screen in the
Calibration submenu to reach the sensor calibrations, or when the blower
speed(s) have been adjusted slightly (but the HEPA filters have not been
replaced) during an annual certification.
3.
Set Filter Life
– This option is seldom selected. It may be used to set the Filter
Life Gauge to a specific percentage, for example, after the display circuit board is
replaced, and the settings from the previous display board need to be
programmed into the new display board.
To access the Filter Life Gauge screen(s), follow the steps in
Adjusting the Blower
Speed
previously shown in this section, until on the
Blower Speed
screen. Then follow
these instructions:
