Notes:
1.
Refrigerant system main PCB EEPROM is designated IC23 on the refrigerant system main PCBs (labeled 29 in Figure 4-2.2 in Part 4, 2.3 “Main PCBs for
Refrigerant System, Inverter Modules and Filter Boards”), designed IC13 on the refrigerant system main PCBs (labeled 19 in Figure 4-2.4 in Part 4, 2.2
“Main PCBs for Refrigerant System, Inverter Modules and Filter Boards”), designed IC23 on the refrigerant system main PCBs (labeled 26 in Figure 4-2.6 in
Part 4, 2.2 “Main PCBs for Refrigerant System, Inverter Modules and Filter Boards”).
