Connecting the Copper pipes between the Indoor and Outdoor unit
The indoor and outdoor units are connected through welded copper pipes. Considering the effect of the
pipe diameter on the system pressure drop, the pipe diameter of the indoor unit and outdoor unit should
be determined by the specifications mentioned in the table under Listing 2.5. Alternatively, contact the
Vertiv support office to seek the help of the technician for gauging the length and diameter.
