18 General Information
6.3 A sense of responsibility
High COPs
It has become essential for air conditioning manufacturers to develop systems that provide high
energy savings. We at Daikin have made great efforts in this field, and the newly-developed VRVIII
delivers highly efficient performance, contributing to high energy savings.
Compliant with the RoHS Directive*
We have been making efforts to facilitate the transition to using RoHS Directive*-compliant
materials for system parts.
Less chances of refrigerant leakage
Conventionally, shutoff valve connections are flanged or flared. In the VRVIII system, the connections for all
outdoor units are brazed, meaning less chance of refrigerant leakage.
We have reached a new level of
efficiency, thanks to the new
advanced features such as the heat
exchanger, the grille and the dual DC
fans.

* RoHS Directive
The RoHS (Restriction of Hazardous Substances (in electrical and electronic equipment)) Directive is an environmental
directive enacted to regulate the use of designated chemical substances (lead, cadmium, hexavalent chromium, mercury,
polybrominated biphenyls and polybrominated diphenylether) in electrical equipment. All household products subject to
this Directive and sold in Europe from July 1, 2006 are legally bound to comply with the RoHS Directive.
Double backup operation in compressors and units
If one of the multiple compressors in
a single outdoor unit system
malfunctions, the other compressors
take over emergency operation.

If one of the unit in a multiple
outdoor system malfunctions, the
other outdoor units provide
emergency operation

until
repairs can be made.
*1. Possible only with single outdoor unit systems that are equipped with two or more compressors. Local setting of the outdoor unit is necessary.
*2. For systems composed of two or more outdoor units
If one compressor
malfunctions...
Emergency operation occurs. *1 Emergency operation occurs. *2
If one outdoor unit
malfunctions...
Emergency operation
can be easily started
by remote control of
the indoor unit.
