alignment with each other prior to starting the
threads of the female coupling nut onto the
male half. Thread by hand the first 3 rotations
of the union nut. If nut does not start by hand,
adjust position of the line set or if necessary
position of unit module.
3) Using a back-up wrench tighten the female
union nut until a definite increase in resistance
is felt. At this point most of threads will have
been covered by the nut. Ensure that the
female and male bodies during any portion of
the wrench installation do not rotate.
4) Make note of the location of the female nut to
the bulkhead. Using a marker or scribe to mark
a line lengthwise. Then finally tighten an
additional one wrench flat or 60
o
. This final
tightening is necessary to ensure a proper leak
proof seal between the couplings.
