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.

The data in this manual are not binding and they can be modified by the manufacturer without notice. Reproduction of this manual is strictly prohibited.

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.
