2
intervals. Follow the applicable legislation.
Formula to calculate the greenhouse gas emissions:
GWP value of the refrigerant × Total refrigerant charge [in
kg] / 1000
Please contact your installer for more information.

When asking your dealer for an intervention, always state:
▪ The complete model name of the unit.
▪ The manufacturing number (stated on the nameplate of the unit).
▪ The installation date.
▪ The symptoms or malfunction, and details of the defect.
WARNING
▪ Do not modify, disassemble, remove, reinstall or repair
the unit yourself as incorrect dismantling or installation
may cause an electric shock or fire. Contact your
dealer.
▪ In case of accidental refrigerant leaks, make sure there
are no naked flames. The refrigerant itself is entirely
safe, non-toxic and non-combustible, but it will
generate toxic gas when it accidentally leaks into a
room where combustible air from fan heaters, gas
cookers, etc. is present. Always have qualified service
personnel confirm that the point of leakage has been
repaired or corrected before resuming operation.
