Note: As the coupling is tightened, the diaphragms in the quick connect couplings will begin to be pierced. As that happens, there will be increased resistance to tightening the swivel nut.
4c. Continue tightening the swivel nut until it bottoms out or a very definite increase in resistance is felt (no threads should be showing). Do NOT overtighten.
5.Use a marker or pen to mark a line on the coupling nut and unit panel. Then tighten the coupling nut an additional
Note: The final 1/4 turn forces two shoulders on the swivel nut end into the beveled surface of the male end, resulting in a sealed
