design Guideline Summary/Selecting Field-Supplied copper tubing
device Connection limitations
Single-zone systems consist of one outdoor unit and one indoor
unit. one of the most critical elements of a single zone system is
the refrigerant piping. Table 16 lists pipe length limits that must be
followed in the design of a Single Zone Art Cool Premier refrigerant
pipe system. Refer to Figure 16 for maximum length and elevation of
piping.
