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 must
be handled with
caution in the vertical
position (maximum
offset from the
vertical : 15°).
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.

All the above limits, temperatures and speeds, are secured by parameters in the drive and
application controller softwares.
VZH028 - VZH065 compressors can be
powered by the dedicated variable speed
drive or third party drive.
When Danfoss drive is selected, check carefully
for compatibility between compressor model
and variable speed drive.
