Outdoor Unit PCBs
There are three types of main PCB: one for the 4kW to 8kW single phase models, one for the 10kW to 16kW single phase
models and one for the 12kW to 16kW three phase models. In addition to the main PCB, all models have an inverter
module and the three phase models also have a filter board.
The locations of each PCB in the outdoor unit electric control boxes are shown in Figures 4-1.1 to 4-1.6 in Part 4, 1.1
“Outdoor Unit Electric Control Box Layout”.
