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.
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 fulfilled.
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, fittings, etc... unless all pressure has been relieved from the compressor.
The compressor must be handled with caution in the
vertical position (maximum offset from the vertical : 15°).
