Operation

7.1

Hygiene preparations for the sample chamber

The sample chamber surfaces and the accessories required for the work
process must be disinfected and cleaned in accordance with the hygiene
guidelines set forth for the application.
7.2

Preparing the sample chamber

Installing the accessories:
1. Lower the front window completely.
2. Open the front cover or move the front window into the maximum opening
position.
3. Position the accessories in the working area of the workplate.
4. Close the front cover.
5. Move the front window to its working position and wait until the airflow has
stabilized.
6. Then place samples into the chamber.
7. To interrupt the work process or for extensive experiment cycles without
manual interference, switch the device to standby mode. When the working
opening is completely closed, the safety cabinet is sealed aerosol-tight.

Response to failure messages

Failure messages are displayed in form of text/number combinations with a code
between ER 1 and ER 5 (see chapter 6.1.6). If one of these codes is displayed,
contact the Technical Service immediately.
To isolate the cause of the failure, the operating personnel must perform only
the following tests and measures:
• Check to see if the exhaust air opening on top of the cabinet is blocked.
• Ensure that the on-site exhaust air system is activated.
• Close doors and windows in the laboratory to prevent drafts.
• Switch off devices in the vicinity of the safety cabinet that cause air
turbulence or emit excessive heat.
• Open flames in the sample chamber may impair airflow conditions.

CAUTION – Operational safety!
The personal and material protection is ensured
only if the airflow system of the device is
working properly.
If the alarm system issues failure messages
when the front window is in the working
position, stop all applications that may release
harmful aerosols!
NOTE – Application of cystostatic agents
For the application of cystostatic agents, the
lowered single-part working plate must be
used. Application of cystostatic agents.
