CHAPTER 1
GENERAL INFORMATION
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.

1.5 Performance data
The performance of the unit depends mainly on the flow rate and the temperature of chilled water (CHILLER) or heated
water (HEAT PUMP) and on the ambient temperature.
Performance values are defined at the time of the contract, refer to the offer data if necessary.
1.6 Noise
Data concerning noise levels are shown in the appendix to the manual.
1.7 How to interpret the alphanumeric string
ATTENTION
See the table concerning the alphanumeric string in the appendix.
The alphanumeric string is shown on the metal data plate on the cover page of this manual.
TECHNICAL PARAMETERS FOR HEAT PUMP SPACE HEATERS AND HEAT PUMP
COMBINATION HEATERS
Parameters shall be declared for medium-temperature application, except for low-temperature heat pumps.
For low temperature heat pumps, parameters shall be declared for low-temperature application.
Parameters shall be declared for average climate conditions.
This symbol shown alongside appears in some refrigerant circuit diagrams and electrical
diagrams. This symbol refers to the alphanumeric string reported in the manual. The upper
box (X) identifies the position of the string, the lower box (Y) identifies the assigned value.
The empty alphanumerical string is circled in the adjacent figure; each
position in the upper row is associated with an alphanumeric value in the
lower row (0, 1, 2, A, B, etc.) and each character is associated with a
specific feature of the unit.
