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°).

1 – Introduction
These instructions pertain to the Danfoss scroll
compressors (hRM/hLM/hCM - hRP/hLP/hCP/
hhP - hRh/hLh/hLJ/hCJ) used for hVAC systems.
They provide necessary information regarding
safety and proper usage of this product.
2 – handling and storage
• handle the compressor with care. Use the dedicated
handles in the packaging. Use the compressor lifting
lug and use appropriate and safe lifting equipment.
• Store and transport the compressor in an
upright position.
• Store the compressor between -35°C and 70°C /
-31°F and 158°F.
• Don’t expose the compressor and the packaging
to rain or corrosive atmosphere.
3 – Safety measures before assembly
Never use the compressor in a flammable atmosphere.
• Mount the compressor on a horizontal flat
surface with less than 7° slope.
• Verify that the power supply corresponds to the
compressor motor characteristics (see nameplate).
• When installing a compressor model hRP/hLP/
hCP/hhP -hRh/hLh/hLJ/hCJ, use equipment
specifically reserved for hFC refrigerants which
was never used for CFC or hCFC refrigerants.
• Use clean and dehydrated refrigeration-grade
copper tubes and silver alloy brazing material.
• Use clean and dehydrated system components.
• The piping connected to the compressor must be
flexible in 3 dimensions to dampen vibrations.
• The compressor must always be mounted with the
rubber grommets supplied with the compressor.
4 – Assembly
• Slowly release the nitrogen holding charge
through discharge and suction ports.

When hRM compressors are used with R417A, the factory
charged oil must be replaced by PVE oil 320hV (120Z5034).
