EDUS391004-N REFNET Pipe System
Installation of Outdoor Units 9
3. REFNET Pipe System
3.1 Layout Example
3.1.1 Heat Pump System
Use of the particular branch fitting appropriate to each individual unit type not only permits the pipes to be laid
with ease but also increases the reliability of the system as a whole.
Units can be added by connecting them directly to the REFNET header or REFNET joint. Further branches cannot be
included in the system below the REFNET header branch.
NOTES:
1. When the capacity ratio of the indoor system to the outdoor unit is more than 100% and when all the indoor units are in operation at
the same time, the rated capacity of each unit will be somewhat reduced.
2. Special purpose REFNET pipe components must be used for all the pipe work. For further details concerning choosing components,
see VRVIII REFNET and Piping Selection Rules.
3. The Daikin REFNET kits are supplied with insulation intended to fit over the main body of the REFNET joint after installation of the
REFNET kit is complete.
4. IMPORTANT: In applications where the REFNET kits are installed in an environment requiring fire-rated materials to be used, it is
necessary for the installer to obtain from a third party supplier and to utilize, for insulation, fire-rated materials that meet all
applicable building codes and other requirements. The factory-provided insulation that is supplied with the REFNET kit should be
discarded in a manner meeting all applicatble laws.
