6-3-3. How to obtain the equivalent piping length
1. PUHY-RP200YJM-B(-BS)
Equivalent length = (Actual piping length to the farthest indoor unit ) + (0.35 x number of bent on the piping) [m]
2. PUHY-RP250, 300YJM-B(-BS)
Equivalent length = (Actual piping length to the farthest indoor unit ) + (0.42 x number of bent on the piping) [m]
3. PUHY-RP350YJM-B(-BS)
Equivalent length = (Actual piping length to the farthest indoor unit ) + (0.47 x number of bent on the piping) [m]
4. PUHY-RP400, 450, 500, 550, 600, 650YSJM-B(-BS)
Equivalent length = (Actual piping length to the farthest indoor unit ) + (0.50 x number of bent on the piping) [m]
5. PUHY-RP700, 750, 800YSJM-B(-BS)
Equivalent length = (Actual piping length to the farthest indoor unit ) + (0.70 x number of bent on the piping) [m]
6. PUHY-RP850, 900YSJM-B(-BS)
Equivalent length = (Actual piping length to the farthest indoor unit ) + (0.80 x number of bent on the piping) [m]
