Outdoor Unit Repair Procedures
2. Removing Electrical Component Box and Duct
(1) Remove the electrical component box
cover (remove 6 screws). (Fig. 3)
• When closing the cover after the repair work,
set the upper fringe of the cover should come
to align inside the electrical component box.
(Fig. 3A)
(2) Remove power and control wires from termi-
nals.
(3) Remove internal wires with extended connec-
tors on the outdoor control PCB.
(Solenoid valves, thermistors, crankcase
heaters and others)
(4) Disconnect power lines connected to the sec-
ondary terminals of the magnetic contactor for
the compressor.
(5) Remove the electrical component box
(remove 2 screws). (Fig. 4)
Be sure to release the locking mechanism
before disconnecting each connector.
(6) Remove the center duct. (Fig. 5)
• The center duct is fitted into the upper and lower
ducts, and held in place by the electrical component
box, an arrangement that makes possible indepen-
dent removal of the center duct.
CAUTION
Be sure to turn off the power before removing the electrical component box. Then check that the power LED (D53)
on the control PCB of the outdoor unit is not lit.
