These units are designed to cool or heat a liquid (WATER in the majority of applications).
The term “WATER” is used for the sake of simplicity to identify the liquid to be cooled, even if the liquid involved is not
water (for example mixtures of water and ethylene or propylene glycol).
The liquid to be cooled must be compatible with the materials used.
This analysis must be carried out when installing the unit.
ATTENTION
Requests for spare parts and any information must be addressed to the local dealer or service centre, specifying
the MODEL and SERIAL NUMBER shown on the unit's nameplate and on the last page of this manual.
