nuts for three pipes, finally tightening them one by
one to connect the pipes.
Use two wrenches for the final tightening of flare
nuts so as not to damage the pipes (figs. 3 & 4).
2-3. Tightening torque for lock nut and flare nut is
based on following.
Discharge pipe: 122N・m (1244.1kgf・cm)
Suction pipe: 122N・m (1244.1kgf・cm)
Injection pipe: 54.9N・m (559.8kgf・cm)
2-4. Apply silicon to cover each lock nut after
tightening.
10mm or more
