Set the remaining cushioning rubber beneath the new compressor leg at the locations shown in the figure 28.
Remove the bolts which are temporarily fastening the 2 pieces of cushioning rubber, and anchor the 3 com-
pressor legs using the bolts, washers, and rubber washers.
Insert the pre-shaped tube assembly at the 3 brazing locations indicated.
Connect the 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.
Perform copper brazing at the 3 brazing locations.
In the same way as during removal, pay particular attention to protection of the oil
equalizing tube connector parts shown in the figure 28.
An O-ring is mounted inside the oil equalizer tube connector parts. It must be pro-
tected and do not lose it.
Follow the instructions in “6. Checking for Leakage After Repair” and check for leaks at the outdoor unit
where the compressor was replaced.
Re-install all components that were removed. Re-install the electrical component box in the same position as
