<Example>
Outdoor unit model: EP300
Total capacity of connected indoor units: 361
* Refer to the pipe connection examples in section 9-4 for the pipes marked with the letters below.
A: ø12.7; 40 m
B: ø9.52; 10 m
C: ø9.52; 15 m
D: ø9.52; 10 m
a: ø9.52; 10 m
b: ø9.52; 5 m
c: ø6.35; 10 m
d: ø6.35; 10 m
e: ø9.52; 10 m
The total length of each liquid piping is as follows:
ø12.7 total length: 40 (A)
ø9.52 total length: 10 (B) + 15 (C) + 10 (D) + 10 (a) + 5 (b) + 10 (e) = 60
ø6.35 total length: 10 (c) + 10 (d) = 20
Therefore, when the piping length from the outdoor unit to the farthest indoor unit is longer than 30.5 m (100 ft),
Amount of additional charge = (40 × 0.11) + (60 × 0.054) + (20 × 0.021) + 0 + 3.5
= 11.6 kg (Fractions are rounded up.)
