Operating and
Installation Instructions
Read and observe these Operating and
Installation Instructions!
For pumps with a drive motor: be sure to
also read and observe the drive motor's
Operating and Installation Instructions,
which must be considered part of the
pump's Operating and Installation Instruc-
tions.
Due to separate certification of the me-
chanical (pump) and electric (drive motor)
parts, the device has two rating plates.
Each rating plate describes only the part
of the device to which it is applied.
An additional letter prefixing the NF model
code is a country-specific designation,
with no technical relevance.
