Procedure
8. Remove electric box assy
1. Remove the grounding wire screw on the
electric box assy and then remove the
grounding wire.
2. Disconnect the wiring terminals of reactor,
compressor, high and low pressure
switch, compressor overload protector,
temperature sensor, outdoor fan motor
and 4-way valve. (See fig 2) Note: keep
pressing the circlip when disconnecting
the wiring terminal of reactor; keep
pressing the retainer when disconnecting
other wiring terminals.
3. Remove the wire inside the wiring groove.
9. Remove blade, motor, motor support,
reactor
1. Remove nuts fixing axial flow blade with
wrench, and then remove the axial flow
blade.
2. Remove 2 screws connecting motor
support and chassis, loosen damper block
and then remove the motor support.
3. Remove 4 screws fixing motor,and then
remove the motor
4. Remove 4 screws fixing reactor sub-assy
and motor support, and then remove the
reactor sub-assy.
10. Remove 4-way valve
Unsolder the spot weld between 4-way valve
and vapour liquid separator, compressor cut-
off valve sub-assy and condenser, and then
remove the 4-way valve.
Note: When unsoldering the spot weld, wrap
the 4-way valve with wet cloth completely
to avoid damage to valve due to high
temperature.
