Label the refrigerant piping (injection and suc-
tion pipes) as well as the associated electrical
control lines of each interior unit with a letter.
Only connect the lines to their associated con-
nections.
NOTICE!
Always pay attention to the affiliation of the
electrical lines and refrigerant piping! The con-
nections of the individual circuits must not be
mixed up. Mixing up the assignment of control
lines and refrigerant piping can have fatal con-
sequences (compressor damage)!
Commissioning of the individual circuits must
be carried out successively.
