Indoor units
❋ When the equivalent length between an outdoor unit and the farthest indoor unit exceeds 90m (295'), upgrade the low
pressure pipe of the main pipe one step.
❋ Note 1) When indoor unit is located at higher level than outdoor unit, allowable height difference is 40m(131ft), but
when the indoor unit is located at lower level than outdoor unit, allowable height difference is 50m(164ft).
Y-joint connection
The distance between the outdoor unit and the farthest indoor unit ≤ 150m (492')
Actual
Ex) 8 indoor units
Length
a+b+c+d+e+f+g+p≤ 150m (492')
Equivalent
The distance between an outdoor unit and the farthest indoor unit ≤ 175m (574')
length
Main pipe The main pipe(a) from the outdoor unit to the first Y-joint should be less than 110m
length (361').
Total
The sum of the total length of pipes should be less then 300m (984').
