2 Outdoor Unit Main PCB
2.1 Types
There are four main PCB types for V5 X outdoor units. 8/10/12HP units share a main PCB type, 14/16HP share a main PCB
type, 18HP has a unique main PCB type, and 20/22HP share a main PCB type. The type label is affixed to the main PCB.
When changing a main PCB, be sure to use the right type of main PCB. Refer to Table 5-2.1.

Notes:
1. The 20/22HP main PCB can also be used on 8/10/12HP units. The only difference is that the 20/22HP main PCB has two inverter modules whilst the
8/10/12HP main PCB has one inverter module. If a 20/22HP main PCB is used on an 8/10/12HP unit, the unit will run normally but LED6 will flash and LED7
will be continuously on.
