c. Make sure the male fitting and female coupling are properly aligned, then start the connection by hand to ensure that it is not cross threaded.

d. Place a backup wrench on the back of the female coupling, then tighten the connection with a wrench until it is tight. At this point, the nut has covered most of the threads on the male fitting. CAUTION! Failure to use a backup wrench may result in damage to the line set and possible refrigerant leaks.

e. Mark a reference line on the female coupling and the remote condenser unit or icemaker panel. Using a backup wrench on the back of the female coupling, tighten the six-sided nut of the female coupling an additional 1/6 turn. See Fig. 8.
