device Connection limitations
A Single Zone Art Cool Premier Wall Mount system consists of one outdoor unit and one indoor unit.
one of the most critical elements of a Art Cool Premier Wall Mount system is the refrigerant piping. Table 11 below lists pipe length limits
that must be followed in the design of a Single Zone Wall Mount refrigerant pipe system:
