The compressor must only be used for its 
designed purpose(s) and within its scope of 
application (refer to «operating limits»). 
Consult  Application  guidelines  and  da-
tasheet available from cc.danfoss.com
 Under  all  circumstances,  the 
EN378 (or  other applicable local 
safety  regulation)  requirements 
must be fulfilled.
The  compressor  is  delivered  under 
nitrogen  gas  pressure  (between  0.3 
and  0.7  bar)  and  hence  cannot  be 
connected as is; refer to the «assem-
bly» section for further details.
The  compressor  must  be 
handled  with  caution  in  the 
vertical  position  (maximum 
offset from the vertical : 15°)
