ATTENTION:
- inform the user if the system contains
5 tCO
2
e or more of uorinated green-
house gases. In this case, a leak test must be
carried out once every 12 months, in com-
pliance with regulation No. 517/2014. is
job must be carried out by professionally
qualied technical personnel only. In the
situation considered above, the installer
(or authorised person in charge of the nal

ATTENTION:
- the compiled label must be applied
near the product load door (for ex-
ample on the inner side of the casing of the
stop valve).
- Make sure that the total refrigerant charge
does not exceed (A), the maximum refrig-
erant charge, which is calculated with the
following formula: Maximum refrigerant
charge (A) = refrigerant charge (B) + max-
imum additional refrigerant charge due to
extension of the piping (C).
- e following table summarises the refrig-
erant charge limits for each product.
