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.
