10 About the system
The indoor unit part of VRV IV-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.
NOTICE
Do not use the air conditioner 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.
INFORMATION
▪ Combination of VRV DX and RA DX indoor units is not
allowed.
▪ Combination of RA DX and AHU indoor units is not
allowed.
▪ Combination of RA DX and aircurtain indoor units is not
allowed.
