Table 4 Refrigerant pipe requirements
When installing multiple indoor units with a single outdoor unit, ensure that the
length of the refrigerant pipe and the drop height between the indoor and outdoor
units meet the requirements illustrated in the following diagram (indoor units
may be located above or below the outdoor unit as long as they meet these height
diff erence requirements):
