1. About this document

1.1. Use of the Operating and Installation Instruc-

tions

The Operating and Installation Instructions are part of the pump.



Forward the Operating and Installation Instructions to any

subsequent owners of the pump.

Customer-specific project pumps (pump models which begin with
"PL" or "PML") may differ from the Operating and Installation
Instructions.



In the case of project pumps, take note of any additionally

agreed specifications.

1.2. Symbols and markings
