starting relay, and other parts.
5) Recover the refrigerant from the low side access valve.
6) Disconnect the discharge and suction pipes by using brazing equipment.
7) Remove the hexagon bolts securing the compressor.
8) To replace the removed parts, reverse the above procedure.
[b] CONDENSER AND DRIER
