3.1.1 Quick-release cover
The Börger MIP principle (Maintenance in Place) starts with the
quick-release cover (1). This cover enables easy access to the
interior of the casing and to all parts subject to wear in the Börger
machine. The pipes on the inlet and outlet can remain connected.
The quick-release cover can be removed after loosening the four
ring nuts (2), (see
Ä
Chapter 6.3.1 “Notes on repair work”
on page 123 and

Chapter 6.3.2 “Opening and closing the quick-
release cover” on page 125).
The Börger machine can be inspected, serviced and repaired
directly at its point of installation.
The supplementary operating manual in the Appendix contains a
description of other cover types, if these types have been supplied.
