VRV 5 heat pump
4P739915-1C – 2024.10
CAUTION
Do NOT touch the heat exchanger fins.
These fins are sharp and could result
in cutting injuries.
4 About the system
The VRV 5 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 "2.1Instructions for
equipment using R32 refrigerant"[46].
The indoor unit part of this VRV 5 heat pump system can be used for
heating/cooling applications. The type of indoor unit which can be
used depends on the outdoor unit series.
WARNING
▪ Do NOT modify, disassemble, remove, reinstall or
repair the unit yourself as incorrect dismantling or
installation may cause an electrical 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.
WARNING
The unit is equipped with a refrigerant leak detection
system for safety.
To be effective, the unit MUST be electrically powered at
all times after installation, except for short service periods.
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.
NOTICE
It is NOT allowed to cool technical rooms like server rooms
and data centres, where year-round cooling is required.
