▪

Piping material:

Phosphoric acid deoxidised seamless copper.

▪

Piping connections:

Only flare and brazed connections are allowed. The indoor

and outdoor units have flare connections. Connect both ends without brazing. If
brazing should be needed, take the guidelines in the installer reference guide
into account.
