(12) Remove the four bolts holding the compressor down. (See Figure 12.)
The two bolts in the front are also holding down the metal sheets.
(13) Tilting the compressor will cause the refrigerant oil to leak. Seal the pipe where it was cut or removed at the brazed
section.
(14) After replacing the compressor, braze the pipes that were removed as they were.
In case of brazing the suction pipe, protect the surrounding components such as the control box, ACC, compressor cover,
and damper with a fire protection panel (e.g., recommended felt soaked in water), attach the supplied pipe,and perform
brazing. (See Figure 13.)
*Perform brazing, referring to "Notes on replacing refrigerant circuit components (check valve, four-way valve, solenoid
valve, and LEV)" in 8-13-3.
(15) The recommended tightening torque for the compressor fixing bolts is 3.0 N·m. Fasten the bolts using a torque wrench or
other tool that can apply the specified torque.
(16) Re-place the compressor covers in the reverse order as they were removed.
*Hold the TH15 wiring in place with the bands to keep the wiring from coming in contact with insulation 2. (See Figures 3
and 7.)
