1. Detachment (P.C. board)
1) Following to work of Detachment of (1).
WARNING
Do not disassemble the inverter for a minute after the
power is turned off since there is a risk of electric shock.
*1. Ensure to bundle
again with a
commercially
available cord
clamp.
*2. Ensure to fix the
clamp filter
where it was
removed when
reassembling
the inverter.
2) Remove a screw fixing inverter box and inverter
cover (Upper side).
3) Loosen a screw fixing inverter box and inverter
cover (Lower side).
4) Cut the cable-tie A1 bundling the fan motor lead
wires, compressor case thermostat lead wires, 4-
way valve coil lead wires and reactor lead wires.
(one position)
