Rubber/metal anti-vibration
isolator
Designed to reduce the vibration.
6.2.2 Spring Anti-Vibration Isolators
6.3 WATER PIPING CONNECTIONS
Figure 5
Unit water pipework must be installed in accordance with national and local regulation and codes.
Follow the recommendations below when designing the water piping circuit (refer to the diagrams included in this
manual).
- Piping should be connected to the unit with flexible joints, to avoid vibration transmission and allow for thermal
expansion (the same procedure should be adopted for the circulating pumps).
The following devices should be located on the piping system:
- Isolating/regulating valves, temperature gauges or thermometer pockets, pressure gauges or binder points
required for servicing operations.
- Serviceable mesh strainer, with a filtration level no larger than 1mm, located on the unit inlet to prevent debris
from entering the heat exchangers.
- Vent valves, to be installed in the upper parts of the circuit, for air bleeding.
- Expansion device with accessories for circuit pressurisation, water thermal expansion compensation and system
filling.
- Unload valve and if necessary drainage tank for circuit emptying during maintenance and seasonal stop.

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.
Standard spring antivibration
isolators
The isolator is fixed to the
unit's baseframe with a nut
and two bolts and washers.
Spring anti-vibration
isolators for heavy
loads
The load of the unit is
supported by the full
surface of the isolators. The
load is not exerted on the
bolt.
