application (refer to «operating limits»). 
Consult Application guidelines 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 «assembly»

 

section for 

further details.

The compressor must be 
handled with caution in the 
vertical position (maximum 
offset from the vertical : 15°)

Installation and servicing of the compressor by 
qualified personnel only. Follow these instructions and 
sound refrigeration engineering practice relating to 

installation, commissioning, maintenance and service.
