FRCC.EI.002.A3.02 © Danfoss Commercial Compressors 05/14
The compressor must only be used
for its designed purpose(s) and within
its scope of application (refer to «ope-
rating limits»).
Consult Application guidelines and da-
tasheet available from cc.danfoss.com
The compressor is delivered under
nitrogen gas pressure (between
0.3 and 0.7 bar) and hence can-
not be connected as is; refer to
the «assembly» section for further
details.
Under all circumstances, the
EN378 (or other applicable local
safety regulation) requirements
must be fullled.
The compressor must be han-
dled with caution in the vertical
