11.2 Handling
The unit must be transported flat and must not sustain any shocks.
11.3 Installation
The unit is normally installed close to the machine being cooled, as indicated on these installation plans.
During the installation, allow for a free space of about 0.5m around the refrigeration unit. This distance
must be 1m in front of the exhaust fan. With these precautions, both ventilation and maintenance access
will be made easier.

chine being cooled can be made with pipes with a cross-section diameter at least equal to that indicated
in the technical characteristics.
See section “9.1.2 Technical specifications” on page 71.
