5.3 Vibration dampers
For active and passive isolation of vibrations and
reducing noise transmission, Alfa Laval strongly
recommends the installation of vibration damp-
ers. Installation of vibration dampers must be
carried out before positioning the unit. Vibration
dampers are to be positioned between the unit
feet and the mounting base with the supplied
M10 screws.

5.4 Expansion joints
Alfa Laval recommends the installation of expan-
sion joints on both inlet and outlet connections.
Expansion joints are elastic elements which, if
properly installed, absorb the thermal expan-
sions of the tubing. Expansion joints are also
helpful in order to reduce vibrations in the piping.

Picture shows an installation example using
threaded bar, nut, grower washer, washer and
locknut (not supplied).
This way vibration dampers can be used to
make the cooler level adjusting the locknut. This
is particularly useful with long units or irregular
basement.
