General
information

About this manual

Caution appears at appropriate
places in this instruction manual.
Your personal safety and the proper
operation of this machine require
that you follow them carefully.
The constructor assumes no liability
for installations or servicing
performed by unqualified personnel.

About the unit

These RAU units are assembled,
pressure tested, dehydrated, charged
and run tested before shipment. The
information contained in this manual
applies to units designated.

Refrigerant

The refrigerant provided by the
constructor meets all the
requirements of our units. When
using recycled or reprocessed

necessary to have a precise analysis
made by a specialized laboratory. If
this condition is not respected, the
