coupling bodies seat or seal or a denite
resistance is felt.
Step 5
Using a marker, mark a line lengthwise
from the coupling union nut to the bulk-
head. Then tighten an additional one (1)
wrench at (60°); the misalignment of the
line will show the amount the coupling
has been tightened. This nal rotation is
necessary to insure the formation of a
leakproof joint.
Note: The O-ring is only an intermedi-
ate seal during the initial connection of a
precharged unit/line set combination. The
O-ring is only used for sealing between
the time the diaphragm is pierced and the
nal metal-to-metal seal is made.
The nal leak-proof seal is a metal-to-met-
al connection made between the male and
female coupling bodies.
Step 1
Upon disconnection, remove O-ring.
Step 2
If O-ring is missing from groove, insure
O-ring is not lodged inside coupling
halves and reconnect without O-ring.
Step 3
Carefully wipe coupling seats and thread-
ed surfaces with a clean cloth, to prevent
the inclusion of dirt or any foreign mate-
rial in the system.
Step 4
Lubricate male half diaphragm with
system-compatible refrigerant oil. Thread
coupling halves together by hand to
insure proper mating of threads. Use
proper size wrenches (on coupling body
hex and on union nut) and tighten until
