Introduction
These refrigeration compressors are intended for incor-
poration into refrigeration systems in accordance with
the EU Machinery Directive 2006/42/EC. They may
only be put into operation if they have been installed
into the refrigeration systems according to these
mounting/operating instructions and if the overall sys-
tem complies with the applicable legal provisions. Ap-
plied standards, see ac-001-*.pdf at www.bitzer.de.
The compressors have been built in accordance with
state-of-the-art methods and current regulations. Partic-
ular importance has been placed on user safety.
These operating instructions must be kept available
near the refrigeration system during the whole lifetime
of the compressor.
