The total weight of the unit, obtained summing up the weight of the unit in the chosen constructive configuration with the weight of
the selected accessories, is referred to the transport weight.
The weight of the accessories not present in the table reported above is negligible for the estimate of the total weight of the unit.

Reference conditions
Performances referred to units with V3 constructive configuration (3 dampers version) operating in cooling mode at NOMINAL conditions A35A27
with STANDARD air flow rate and available static head.
The sound power level is obtained starting from the data declared by the manufacturer of the fans.
