21.1 General information, personnel qualification
• Maintenance
See chap. 21.2
• Simple troubleshooting
Chap. 21.3 describes troubleshooting by operating personnel. It does not require technical intervention
into the chamber, nor disassembly of chamber parts.
For personnel requirements please refer to chap. 1.1.
• Detailed troubleshooting
If errors cannot be identified with simple troubleshooting, further troubleshooting must be performed by
BINDER Service or by BINDER qualified service partners or technicians, in accordance with the de-
scription in the Service Manual.
For personnel requirements please refer to the Service Manual.
• Repair
Repair of the chamber can be performed by BINDER Service or by BINDER qualified service partners
or technicians, in accordance with the description in the Service Manual.
After maintenance, the chamber must be tested prior to resuming operation.
• Electrical testing
To prevent the risk of electrical shock from the electrical equipment of the chamber, an annual repeat
inspection as well as a test prior to initial startup and prior to resuming operation after maintenance or
repair, are required. This test must meet the requirements of the competent public authorities. We rec-
ommend testing under DIN VDE 0701-0702:2008 in accordance with the details in the Service Manu-
al.
For personnel requirements please refer to the Service Manual.
