The UV disinfection time is preset. However, this setting can be changed,
if required.
1. Turn the unit on and move the window to the work position.
2. Press and hold the UV key until the preset time is displayed.
3. To increase the time, press the internal power supply key. Each time
the key is pressed, the time increases by 30 minutes.
4. To reduce the time, press the sample chamber light key. Each time the
key is pressed, reduces the time by 30 minutes.
5. To save the value, press the UV key. The display shows the operating
hours again.
Note The UV disinfection time is adjustable from 0:00 (disabled) to 24:00
s
hours.
NSF/ANSI 49, Annex G recommends a microbiological space
decontamination when maintenance work, filter changes, and performance
tests require access to any contaminated portion of the cabinet and before
the BSC is moved to another location. A microbiological space
decontamination may also be required by the BSC owner or user before
certification or as a part of their work procedures. NSF/ANSI 49 provides
recommended procedures for microbiological space decontamination using
formaldehyde and chlorine dioxide. NSF/ANSI 49 also recognizes that
alternative methods including the use of vaporized hydrogen peroxide are
sometimes validated and approved by BSC owners and users. The
appropriate method and procedure should be reviewed and approved by
interested parties including the BSC user, institution biological safety
officer, and BSC certification and service personnel as appropriate.
Warning Decontamination with formaldehyde and chlorine dioxide must
be performed in accordance with the specifications of NSF/ANSI 49,
Annex G. As this procedure has considerable risks, it must only be
performed by specially trained and authorized service personnel! Before
Decontamination with chlorine dioxide, the BSC must be sealed at the
exhaust opening and front opening to eliminate exposure to chlorine
dioxide, of the power supplies, PCBs and other components under the
front canopy as they are susceptible to damage from the process .
Thermo Fisher Scientific has developed validated procedures for the
decontamination of the Thermo Scientific 1300 Series A2 using the Steris
VHP (Vaporized Hydrogen Peroxide) system. These procedures are
available on request.
