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.
