Set up the UV irradiator in the test chamber and connect it.
Close the front window
Switch
State
UV
Switch (keyswitch) = close front window & DOWN button: As soon as the
front window is lowered, an acoustic
alarm will indicate hazards associated with lowering the window. The red
indicator light shows that the window
is not in its proper position.
In the window's home position, the
red indicator light also shows that
there are now problems with the ventilation.
The irradiator cannot be turned on until the front window is completely closed.
Turn on the UV mode.

When using alcohol-based disinfectants, please note:
avoid EXPLOSION HAZARDS caused by alcohol vapors in the air. Use as little alcohol as possible. Follow all applicable federal, state, and local ordinances
(in Germany: ZH 1/598).
Only place clean, disinfected tools/aids in the test
chamber. Limit the tools/aids to a minimum, e.g., no
writing utensils, packaging, or similar materials.
If larger objects or aids are placed in the test chamber, the retention capability (personal protection) of
the safety cabinet may be impaired. Only set up
equipment towards the back of the work surface.
The uninterrupted airflow through the working openings of these safety cabinets and
the low-turbulence displacement flow (laminar flow) in the test chamber are decisive
factors for personal and product protection.
Avoid any negative influences on the airflow while
working in the test chamber.
These can be the result of:
- Rapid hand, arm, or body movements both in, as
well as in front of the test chamber.
Working Guidelines
Aside from the information previously provided in the
"Safety Information" section, please also not the following:
No work may be performed in the test chamber if optical or acoustic alarms are on.
The microbiological effectiveness and safety of the
unit depends to a great extent on the proper conduct
of the individuals working with the safety cabinet.
Follow all applicable federal, state, and local guidelines and the information in this handbook.
Only raise or lower the front window electrically. Manual lifting can result in problems with
the window mounting.
Turn the safety cabinet on at least 15 minutes prior to
starting work in order for the test chamber ventilation
to reach proper equilibrium.
The front window must be in its operating position to
ensure safe working conditions.
Always wear appropriate protective gear, e.g.,
gloves, face protector, and protective clothing. Remove all jewelry.
- Covering the air vents in the work panel.
- Large volume objects and equipment.
- Rapidly moving equipment with , e.g., stirrers, etc.
- Heat-generating equipment, e.g., Bunsen burners.
If Bunsen burners must be used, employ only safety models.
- Only employ equipment that generates heat if the
ventilation system is switched on.
Do not allow filter elements to be damaged by heat
sources - Contamination Hazard - .
Work interruptions:
If work at the safety cabinet is interrupted, make sure
that any contamination by materials released in the
safety cabinet is prevented.
Operate the safety cabinet in the standby mode, with
the glass window sealed.
Disinfect and clean the test chamber surfaces regularly.
Use only lint-free materials to wipe down test chamber surfaces. Always run the ventilator during all
disinfecting work. Recommended disinfecting agent:
