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