If total refrigerant amount of system isover than 100 kg, the system has to be divided into smaller system, each less than 100 kg.note 2) Required conditionClassification Condition ExampleFirst branch joint ~Farthest Indoor unit45 m ≤ b, l+m, q ≤ 90 m: Size of the branch pipe (b,l, m, q) must be increased by 1 gradeMCUMCUMCUMCUnhml o pq rCondition of totallength of extendedpipea+(bx2) + c + d + e + f + g + h + I + j + k + l + m +n + o + p + q + r ≤ 500MCU ~ Each indoor unit c + d, c + e, c + f, g, h + I, h + j, h + k, n, o, p, r ≤ 45Difference between the distance of the outdoor unit to the farthest indoorunit and nearest indoor unit ≤ 45 (a+b+h+k) - (a+b+c+d) ≤ 45note 3) For indoor units to which no MCU is connected, be sure to set their options to “Cooling only indoor unit,” and thenconnect them to a low pressure gas pipe and a liquid pipe Be sure to combine the cooling only indoor units so thattheir total capacity becomes 50% or less of the total capacity of all indoor unitsnote 4) In case of connecting more than one indoor unit in one MCU Port, the below indoor units can not be combinedERV plus (AM✴✴✴FnKDE✴✴), OAP duct(AM✴✴✴✴nEPE✴✴), Hydro Unit HE(AM✴✴✴FnBD✴✴), Hydro UnitHT(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 can not be combined to more than oneRefrigerant pipe installation
