11.9  Compressor sound level

Note: Tested in Rated condition of EN12900

11.10  SOUND GENERATION IN REFRIGERATION SYSTEM

Noise and vibrations coming from system or service may come from these sources:

•  sound radiation – extend by air
•  mechanical vibrations – extended along the parts of the unit and 

structure

•  gas pulsation – distributed by cooling medium (refrigerant)

The replacement of a compressor is an onerous task and requires an accurate diagnosis of the system 
before deciding to proceed with it.

Improper procedures to remove the failed compressor and install a new one, may 
cause injury to person, release of refrigerants and oil to the environment, fire and 
damages to propriety.

When repairing a refrigeration system, replacing a compressor and installing a new 
ones, follow all applicable international regulation and standards (like EN 378-4 or 
similar), and the local ones, as well as the safety warnings and recommendations 
indicated in these installation instructions. 

The compressor replacement must be carried out in properly ventilated ambient. 
Disconnect the system from the electrical power.
