Design compressor mounting
Compressors CH290 and 485 dedicated for parallel (versions AA and AB) mounting come delivered with rigid
mounting spacers for parallel mounting.
CH290 and CH485 used in single applications, are delivered with flexible grommets. The grommets must be
compressed until contact between the flat washer and the steel mounting sleeve is established. The grommets
attenuate to a great extent the transmission of compressor vibrations to the base frame.
The required bolt size for the CH290 and 485 compressors is HM8-55. This bolt must be tightened to a torque of 21
Nm.
