Step Component
12 Compressor 12) Burn the connection parts of the SV4 pipe, oil
replacement balance pipe (suction pipe side) and discharge
(continued) pipe with the burner, and remove. (3 positions)
(Fig. 12-8)
CAUTION
• Be careful when brazing by the burner to
remove the pipes. Oil remaining in the pipes
may generate fire when the brazing melts.
• Apply protection to painted surfaces on the
compressor and accumulator to prevent
burning when brazing.
13) Cut the oil balance pipe (compressor side) at the
instructed position. (Fig. 12-9)
CAUTION
Burning the brazed areas of the oil balance pipe
assembly with the burner before cutting the compressor
oil balance pipe may cause a fire. (Fig. 12-9)
14) Burn the brazed areas of the oil balance pipe with
the burner, and remove. (1 position) (Fig. 12-10)
15) Burn the suction pipe (compressor side,
accumlator side) and discharge pipe (compressor
side) with the burner and remove its from
compressor. (Fig. 12-11)
* The SV3 connection piping is connected to the
suction pipe, so when removing the suction
pipe pay careful attention not to deform theSV3
connection piping. (Fig. 12-12)
16) Remove the compressor bolts fixing the
compressor to the bottom plate.
