1. Exchange the catalyst cartridge in the chamber with a reactivated one.
2. Remove and empty the condensate collection container as needed.
3. Change the anaerobic monitoring strip at least once per 24 hours, or as often as necessary
so that the strip in the workspace chamber remains moist.
4. Check that the pass box gaskets are properly seated.
5. Check the cuffs on the sleeve assemblies for holes, tears, and other signs of wear that may
compromise integrity. Replace if necessary.
6. Check the incubator temperature to ensure the set point is correct.
7. Record the gas cylinder reading(s).
8. Change or reactivate the carbon volatile compounds scrubber media, if installed. Please
see the Activated Carbon Scrubber and Rejuvenation Cycle on page 55 in the
Operation section.
9. Check the water level in the manometer. While the chamber is operating under its normal
overpressure of 0.5 inches, the water level should be even with the lower of the two
reference rings.
10. Clean and disinfect the workspace chamber in accordance with your laboratory or
production protocols, or regulatory requirements.

ONSUMPTION
A sealed and undisturbed BACTRON workstation will typically go for more than 30 minutes
between gas injections into the workspace chamber. When injecting, the Chamber Gas light will
illuminate, accompanied by a pair of audible clicks from the chamber gas solenoid opening and
closing. Pass box cycles, entering or exiting the arm ports, and working within the workspace
chamber will temporarily increase the frequency of gas injections.
The manometer water column should be depressed by approximately 0.5 inches (1 cm) under
normal operating conditions.
Injections taking place every thirty minutes or less in an undisturbed unit may indicate a small leak.
Injections every 10
– 30 seconds are indicative of a large leak.
