Introduction
These refrigeration compressors are intended for incor-
poration into refrigeration systems in accordance with
the 2006/42/EC Machinery Directive. They may only be
put into operation if they have been installed in the refri-
geration systems according to these Mounting/Operat-
ing Instructions and if the overall system complies with
the applicable legal provisions (applied standards: see
declaration of incorporation).
The compressors have been built in accordance with
state-of-the-art methods and current regulations. Partic-
ular importance was placed on user safety.
These Operating Instructions must be kept available
near the refrigeration system during the whole lifetime
of the compressor.
