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 datasheet
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 «assembly»
section for
further details.
The compressor must be
handled with caution in the
vertical position (maximum
offset from the vertical : 15°)
Installation and servicing of the compressor by qualified personnel only. Follow these instructions and sound refrigeration engineering
practice relating to installation, commissioning, maintenance and service.
A

B
: Serial number
C
: Refrigerant
D
: Supply voltage, Starting current & Maximum
operating current
E
