Distribution Kit Model Remarks
If the sum of pipe length (b+c+d+e+f+g+p) is over 45m,(but not exceed : 90m)
Increase pipe size of b, c, d, e, f, g. (b, c, d, e, f, g : pipe 1 size up)

Required condition Example
*2) As an outdoor unit is located in a lower position than indoor unit, level difference is 40m.
