Where possible, use the two-point suspension system
to lift the compressor.
Fig. 1: Standard: Lifting the compressor, two-point suspension: Ex-
ample HS.85
Fig. 2: Option: Lifting the compressor, single-point suspension: Ex-
ample HS.95

4.2 Installing the compressor

Install/mount the compressor horizontally. Take suit-
able measures if the compressor is operated under ex-
treme conditions (e.g. aggressive atmosphere, low out-
side temperatures, etc.). Consultation with BITZER is
recommended.
4.2.1

Vibration dampers

Solid mounting is possible. However, to reduce struc-
ture-borne noise, it is recommended using vibration
SB-110-3
dampers that have been especially tuned-in to the com-
pressors (option).
NOTICE
!
!
Do not mount the compressor solidly on the
heat exchanger!
Risk of damage to the heat exchanger (fatigue
fractures).
Mounting the vibration dampers
Screws (see figure 3, page 7) are sufficiently
tightened when the upper rubber disc shows first signs
of deformation.
