(5) Place the remaining cushioning rubber onto the new compressor.
(6) Anchor the 3 compressor legs using the bolts, washers, and rubber washers.
(7) Remove the flare nut from the new compressor, and connect the tube-with-flare-nut.
(8) Shape the tubes and insert them at the 2 brazing locations.
(9) Connect a manifold gauge to the high- and low-pressure outlet ports at the outdoor unit where the compres-
sor was replaced. Connect the manifold gauge to a nitrogen cylinder and perform nitrogen gas replacement.
(10) Perform copper brazing at the 2 brazing locations.
(11) Follow the instructions in "5. Checking for Leakage After Repair" and check for leaks at the outdoor unit where

Removal
(1) Connect the manifold gauge to the high- and low-pressure outlet ports at the outdoor unit where the compressor
will be replaced. Connect the manifold gauge to a nitrogen cylinder and perform nitrogen gas replacement.
(2) Remove the panels and the corresponding parts from the outdoor unit where the compressor will be replaced.
(3) Remove the cap and acoustic material that surrounds the compressor.
At this time, also check for leaks at the flare nut connection on the tube-with-flare-nut.
Insert the material from this
position. It is easier to attach it.
Be sure to check for looseness of the power terminal connection at the compressor
terminal plate, and to check by pulling vertically on the connections. If the terminals
become disconnected easily, replace the wiring Assy.
