INFORMATION

Also read the precautions and requirements in the

"2 General safety

precautions"

[

Also see

"7.1.4 Special requirements for R32 units"

[

71] for additional

requirements.

▪

Piping length:

See

"7.1.3 Installation site requirements of the indoor unit"

[

70].

▪

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.

▪

Flare connections:

Only use annealed material.
