5 About the system
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 mildly flammable, 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.
NOTICE
Do NOT use the system for other purposes. In order to avoid any quality
deterioration, do NOT use the unit for cooling precision instruments, food, plants,
animals, or works of art.
NOTICE
For future modifications or expansions of your system:
A full overview of allowable combinations (for future system extensions) is available
in technical engineering data and should be consulted. Contact your installer to
receive more information and professional advice.
CAUTION
This unit is equipped with electrically powered safety measures, such as a refrigerant
leak detector. In order to be effective, the unit must be electrically powered at all
times after installation, except for short service periods.
