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
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 «assem-
bly»
section for further details.
The compressor must be
handled with caution in the
vertical position (maximum
offset from the vertical : 15°)
