Do not throw away any of the accessories until installation is completed.

Be sure to read this manual before installation and follow the instructions carefully when performing installation.

For installation of the outdoor units, refer to the installation manual of the outdoor unit.

The installation of refrigerant pipes between outdoor and indoor units needs to be arranged by refnet joints and refnet headers, and is to be purchased separately.

For combination of outdoor units follow Engineering Data.

The quantity and selection procedure for use of joints with an angle of 90° only apply to front or bottom connection installations.

For lower front connection installations, the quantity and selection procedure are different. Please refer to the dedicated instructions.

Joints for pipes with the same diameter are only needed for bottom connection installations. See dedicated instructions for quantities and specifications.

■

■

Use piping with temper grade in function of the pipe diameter as listed in the table below.

The pipe thickness of the refrigerant piping must comply with relevant local and national regulations.

The minimum pipe thickness for R410A piping must be in accordance with the table below (for design pressure of 4.0 MPa (40 bar)).
