The dismantlement method of the electrical box spear part.
There are two type of electrical box,old and divide version.
PCB board has two modes
：
mode1
：
PCB board is a complete block,and in the electicial box of the same box with the
transformer; (Fig.19)
model 2
：
PCB board divide into 2 blocks
，
the main PCB board is in the electrical box ( Fig.22) ,the other
power PCB board is in the left of the compressor
’
s box with the transformer. ( Fig.21)
