Installation and servicing of the compressor by qualied personnel only. Follow these
instructions and sound refrigeration engineering practice relating to installation,
commissioning, maintenance and service.
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
Never operate
compressor without
terminal box cover in
place and secured.
Under all circumstances, the
EN378 (or other applicable local
safety regulation) requirements
must be fullled.
Wear protective goggles and
work gloves.
The compressor is delivered under nitrogen gas pressure
(between 0.3 and 0.4 bar / 4 and 6 psi). Do not disassemble
bolts, plugs, ttings, etc... unless all pressure has been
relieved from the compressor.
The compressor must be handled
with caution in the vertical
position (maximum oset from
the vertical : 15°).
