INFORMATION

The units described in this manual may be referred to below as “WATER CHILLERS”.
This manual is addressed to personnel responsible for installing, using and servicing the unit.
The units were constructed using components made by premium quality manufacturers and the entire design, production and 
control process was carried out in compliance with standard ISO 9001.
In the majority of applications the liquid in the user circuit is water so henceforth the term “WATER” will be utilised, even if 
the liquid in the user service is different (for example mixtures of water and ethylene or propylene glycol).
Hereinafter the expression “PRESSURE” is used to indicate relative pressure.
The following symbols are to be found on the decals affixed to the unit and also in the dimensional drawings and refrigerant 
circuit diagrams. The meaning of each symbol is indicated below:

1 . 1

H o w   t o   i n t e r p r e t   t h e   m o d e l

ATTENTION

 

 This manual, which is addressed to users, installers, and service personnel, supplies all the technical information

required to install and work with the unit and to perform the routine maintenance operations required to maximise its
working life.
Use only genuine parts when carrying out routine maintenance or repairs.
Requests for SPARE PARTS and any INFORMATION concerning the unit must be made to your dealer or nearest service
centre, specifying the MODEL and SERIAL NUMBER shown on the unit’s dataplate and on the last page of this manual.
