IDENTIFICATION The unit can be identified through: - - Rating plate It bears the technical and performance data of the equipment. Should this plate be damaged or mislaid, ask your local Technical Support Service for a duplicate. Tampering with the rating plate, removing it or whatever else does not allow a sure identification of the product hinder any installation or maintenance interventions.
The manufacture is not held responsible for the non-observance of the instructions contained in this manual, for the consequences of any unexpected operation or for any translations from which wrong interpretations may arise. This appliance must be installed in accordance with the applicable national and local regulations and must be only used in a sufficiently ventilated environment.
The units are divided into two families: They use a scroll-type rotating compressor, mounted on antivibration supports inside an adequate compartment, and – HEAT PUMPS, BESST series: some available with single- electronically-controlled variable-speed helical fans, which phase power supply, others with three-phase power ensure...
