applicable legislation. Contact your installer for more information.
NOTICE
Applicable legislation on fluorinated greenhouse gases requires that the refrigerant
charge of the unit is indicated both in weight and CO
Formula to calculate the quantity in CO
refrigerant × total refrigerant charge [in kg] / 1000
Contact your installer for more information.
WARNING
The maximum indoor capacity index which can be connected to a BS unit port is
determined based on the smallest room served by that port.
In case the system serves the lowest underground floor of a building, there is an
extra limit to the maximum allowable total refrigerant amount. This maximum
refrigerant amount is determined based on the area of the smallest room on the
lowest underground floor.
See "16 Special requirements for R32

NOTICE
The refrigerant charge of the system must be less than 63.8 kg. This means that in
case the calculated total refrigerant charge is equal to or more than 63.8 kg you must
divide your multiple outdoor system into smaller independent systems, each
containing less than 63.8 kg refrigerant charge. For factory charge, refer to the unit
name plate.
