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 

c o m p r e s s o r 
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.
