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"

Outdoor unit model: PURY-EM300YNW-A
Main HBC controller 1 model: CMB-WM108V-AA

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
