Therefore, when the piping length from the outdoor unit to the farthest HBC controller is shorter than 10 m (32
ft),
Amount of additional charge = (41 × 0.09) + 2.8 × 2
(2) Units "ft" and "oz"
<Formula>
・When the piping length from the outdoor unit to the farthest HBC controller is 10 m (32 ft) or shorter
Amount of additional
=
charge (oz)

<Example>
Outdoor unit model: PURY-EM300YNW-A
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 section 9-4 for the pipes marked with the letters below.
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 follows:
ø5/8 total length: 59 (A
ø5/8 total length: 16 (A
Therefore, when the piping length from the outdoor unit to the farthest HBC controller is shorter than 10 m (32
ft),
Amount of additional charge = (133 × 0.98) + 99 × 2
