4.2 ANTI-VIBRATION ISOLATORS (option)
It is recommended that the unit is installed on rubber or spring anti-vibration mountings, supplied as an option, to
reduce vibrations transmitted to the building structure. It is advisable to use rubber isolators for units installed in
the basement, or ground floors in contact with the earth, and spring isolators for units installed on intermediate
floors.
The anti-vibration isolators must be installed before the unit is positioned.
Ensure that during lifting the unit is firmly secured with straps.
4.2.1 Rubber Anti-Vibration Isolators
Rubber isolators are made of an upper metallic bell with a fixing screw to the base-frame of the unit. The isolator
is fixed at the foundation via 2 holes on the flange. On the flange there is a number (45, 60, 70 ShA) which
identifies the hardness of the rubber isolator. The dimensional drawing, enclosed in the machine, shows the unit
footprint with the position and weight of each isolator.

4.2.2 Spring Anti-Vibration Isolators
Anti-Vibration Isolators with cylindrical springs are recommended to reduce any mechanical and sound vibration.
Each isolator has a code which identifies the maximum permitted load.
When installing spring Anti-Vibration Isolators, it is compulsory to carefully follow all recommendations and assembly
instructions. The dimensional drawing, enclosed in the machine, shows the footprint with the position and weight
of each isolator.

The isolator is fixed to the
unit's baseframe with a nut
and two bolts and washers.

The load of the unit is
supported by the full
surface of the isolators. The
load is not exerted on the
bolt.
