If a multilingual fluorinated greenhouse gases label is delivered with the unit (see
accessories), peel off the applicable language and stick it on top of
a

NOTICE
Applicable legislation on
fluorinated greenhouse gases
requires that the refrigerant
charge of the unit is indicated both in weight and CO
2
equivalent.
Formula to calculate the quantity in CO
2
equivalent tonnes:
GWP value of the
refrigerant × total refrigerant charge [in kg] / 1000
Use the GWP value mentioned on the refrigerant charge label.

Fix the label on the inside of the outdoor unit. There is a dedicated place for it
on the wiring diagram label.
8.5 Preparing water piping
8.5.1 Water circuit requirements
INFORMATION

DIN 4726. The diffusion of oxygen into the piping can lead to excessive corrosion.
▪
Connecting piping – Legislation.
Make all piping connections in accordance with
the applicable legislation and the instructions in the "Installation" chapter,
respecting the water inlet and outlet.
▪
Connecting piping – Force.
Do NOT use excessive force when connecting the
