Note 1) When indoor unit is located at higher level than outdoor unit, allowable height dierence is 110m, (If the height dierence is over
40m, contact your local dealer for more information.) but when the indoor unit is located at lower level than outdoor unit, allowable
height dierence is 110m (If the height dierence is over 50m, need to decide whether to install PDM kit or not.)

Classication Condition Example
First branch
joint ~ Farthest
Indoor unit
45 m ≤ b+h+k, l+m+q, l+r ≤ 90 m : Size of the branch liquid and
low pressure gas pipes (b, l, m) must be increased by 1 grade.
Total length of
extended pipe
If the size of pipe (main pipe), between the rst branch joint
and the outdoor unit, is not increased by 1 grade, a+(b+l+m)
x2+c+d+e+f+g+h+i+j+k+n+o+p+q+r ≤ 1000 m
If the size of pipe (main pipe), between the rst branch joint
and the outdoor unit, is increased by 1 grade, (a+b+l+m)
x2+c+d+e+f+g+h+i+j+k+n+o+p+q+r ≤ 1000 m
MCU ~ Each
indoor unit
c+d, c+e, c+f, g, h+i, h+j, h+k, n, o, p, q, r ≤ 45 m
Dierence between the distance of the outdoor unit to the farthest indoor unit and
nearest indoor unit ≤ 45 (a+b+h+k) - (a+b+c+d) ≤ 45
Note 3) For indoor units to which no MCU is connected, be sure to set their options to “Cooling only indoor unit,” and then connect them to a
low pressure gas pipe and a liquid pipe. Be sure to combine the cooling only indoor units so that their total capacity becomes 50% or
less of the total capacity of all indoor units.
Note 4) In case of connecting more than one indoor unit in one MCU Port, the below indoor units cannot be combined. ERV plus
(AM
FNKDE), OAP duct(AMJNEPE), Hydro Unit HE(AMFNBD), Hydro Unit HT(AMFNBF), AHU kit
(MXD-KAN, MCM-DN)
Note 5) In case of connecting two MCU ports with Y-joint, the indoor units cannot be combined to more than one.
