12 Compressor 1. Removing the malfunctioning compressor
replacement
1) Collect the refrigerant gas with the recovery
equipment.
2) Remove the front panels, upper panel,
discharge cabinets, side panels, reactor box,
and Inverter assembly. [Step.1, Step.2, Step.3,
Step.4, and Step.5]
3) Remove the screws the inverter fixing plate
(back), heat exchanger, and remove the
inverter fixing plate (back).
(M4×10, 3) (Fig. 12-1)
4) Remove the screws the partition plate and
inverter fixing plate (lower), and remove the
inverter fixing plate (lower).
(M4×10, 3) (Fig. 12-2)
5) Remove the screws the packed valve and ball
valve from the valve fixing plate.
(hexagonal screws: M5×16, each 2) (Fig. 12-4)
6) Remove the screws the partition plate (lower)
and valve fixing plate.
(M4×10, 2) (Fig. 12-3)
7) Remove the sound-insulation mat (outside,
inside).
8) Remove the screws the partition plate (lower),
bottom plate, and heat exchanger (lower), and
remove the partition plate (lower).

9) Remove the TD sensor and binding band the
discharge pipe. (Fig. 12-6)
10) Brazing the discharge and suction pipes

to remove the soldering. (Fig. 12-7)
CAUTION
Be careful when brazing the soldering with
the burner to remove the pipes. Oil remaining
in the pipes may generate fire when the
soldering melts.
11) Pull up the discharge and suction pipes.
