FRCC.EI.002.A1.02 © Danfoss Commercial Compressors 04/08
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
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 «as-
sembly»
section for further details.
Under all circumstances, the
EN378 (or other applicable local safety
regulation) requirements must be
fulfilled.
The compressor must be handled
with caution in the vertical posi-
tion (maximum offset from the
vertical : 15°)
