32
The VRV 5-S uses R32 refrigerant which is rated as A2L and is mildly flammable. For
compliance with the requirements for enhanced tightness refrigerating systems
and IEC60335-2-40 the installer must take extra measures. For more information,
see "3.1 Instructions for equipment using R32
The indoor unit part of this VRV 5-S heat pump system can be used for heating/
cooling applications. The type of indoor unit which can be used depends on the
outdoor units series.
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.
