FOR THE INSTALLER: Precharged Lines
COUPLING INSTRUCTIONS
CAUTION
The couplings on the sets of precharged lines are
self sealing when installed properly. Carefully
follow the instructions:
1. Remove the protector caps and plugs. Wipe the
seats and threaded surfaces with a clean cloth to
be certain that no foreign matter remains on them.
2. Lubricate the inside of the couplings, especially
the O-Rings with refrigerant oil.
Connect the 3/8 inch liquid line (schrader valve
end) to the remote condenser fitting marked
"liquid line".
Connect the other end of the liquid line to the
ice maker fitting marked "liquid line."
Connect the 1/2 inch discharge line (schrader
valve end) to the remote condenser fitting
marked "discharge line".
Connect the other end of the liquid line to the
ice maker fitting marked "discharge line".
3. Begin tightening the couplings together by
hand, then using two wrenches (it is important that
ONLY the nut on the precharged lines be turned,
the other parts of the couplings must NOT be
allowed to turn or the process will tear out the
diaphragms and they will be loose in the
refrigeration system) tighten the coupling until it
bottoms out or a definite increase in resistance is
felt.

4. Using a marker or pen, mark a line lengthwise
from the coupling union nut to the bulkhead. Then
tighten the coupling and additional 1/4 turn. As the
nut turns, the line will show when 1/4 turn is made.
5. After all connections are made, and after the
king valve has been opened, check the couplings
for leaks.
