consider the following:
• the technical spaces necessary for the machine and
system
• the place where the machine will be installed
• the transport of thermal carrier fluids and relevant
connections to the unit:
o water
o air
If these aspects are not evaluated carefully, they can affect
the performances and the working life of the unit.
FUNCTIONAL CLEARANCES
When placing the unit, please respect the functional
clearances indicated in DIMENSIONS section.
The functional spaces need to be observed because of the
following:

• to allow the performance of all maintenance operations
• to protect the authorized operators and exposed people
If more units are placed close to one another, the functional
spaces must be doubled.
