Example 1)
Connectable indoor unit : ASUA9TLAV x 4 + AUUB18TLAV x 2 + ARUL9TLAV
Amount of "Units" : 1 x 4 + 1 x 2 + 1 x 1 = 7
Example 2)
Connectable indoor unit : ARUH72TLAV1 + AUUB18TLAV x 2 + ARUL9TLAV
Amount of "Units" : 3 x 1 + 1 x 2 + 1 x 1 = 6
Example 3)
Connectable indoor unit : ARUV12TLAV + AUUA9TLAV x 2 + ARUL9TLAV x 2 + UTP-RU01AH x 1
+ UTP-RU04BH x 1
Amount of "Units": 4 x 1 + 1 x 2 + 1 x 2 + 1 x 1 + 4 x 1 = 13
Select the power cable type and size in accordance with local regulations.
