Compatibility with the piping of current installations where R22 or R407C are used.
The new IVX Premium and IVX Standard are compatible with those installations that have been operating with R22 or
R407C. This allows installing the IVX Premium/Standard Outdoor Units, which operate with R410A, without having to
change piping installation, even when the thickness is less than the R410A piping specications.
This option is easily congured through the DSW2, by setting pin 4 ON. With this setting, the control system adjusts the
pressure in order to avoid damage to the existing pipe for R22, in case that its thickness is less than the R410A piping
specications. Otherwise, no settings are necessary (factory setting DSW2 pin 4 OFF)
Before applying this option, it is important to have special care with preliminary operations that need to be performed on
the installation (cleaning pipes, changing lters, vacuum, etc.) and restrictions (pipe lengths, etc.).
It is important not to disregard the previous operations and the established restrictions; otherwise, serious damage can be
caused to the equipment and installation.
