<Example>
Outdoor unit model: PURY-EM300YNW-A1
Main HBC controller 1 model: CMB-WM108V-AA
Main HBC controller 2 model: CMB-WM108V-AA
Sub HBC controller model: CMB-WM108V-AB
* Refer to the pipe connection examples in Fig.2.4.2 (P.2).
A : ø5/8; 59 ft
1
A : ø5/8; 16 ft
2
A : ø5/8; 32 ft
3
B: ø5/8; 26 ft
The total length of the high-pressure piping and liquid piping in each case is as fol-
lows:
ø5/8 total length: 59 (A )
1
ø5/8 total length: 16 (A ) + 32 (A ) + 26 (B) = 74

Therefore, when the piping length from the outdoor unit to the farthest HBC con-
troller is longer than 10 m (32 ft),
Amount of additional charge = (133 × 0.57) + 99 × 2
= 327.1 oz (Fractions are rounded up.)
