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 data-
sheet 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 «assembly»
section for further details.
Under all circumstances, the
EN378 (or other applicable local safety
regulation) requirements must be
fullled.
The compressor must be handled
with caution in the vertical position
(maximum oset from the vertical :
15°)
