Coupling Instructions

The couplings on the ends of the pre-charged line
sets are self-sealing when installed properly.
Follow these instructions carefully.
Initial Connections
1. Remove the protector caps and plugs. Wipe the
seats and threaded surfaces with a clean cloth to
remove any possible foreign matter.
2. Lubricate the inside of the couplings, especially
the O-rings, with refrigerant oil.
3. Position the fittings on the correct connections
on the condenser and ice machine.
•
The larger tube connects to the remote
condenser fitting marked "discharge line".
•
The smaller tube connects to the remote
condenser fitting marked "liquid line".
•
The other end of the larger tube connects to
the ice maker fitting marked "discharge line".
•
The other end of the smaller tube connects
to the ice maker fitting marked "liquid line".
Final Connections:
4a. Begin by tightening the couplings together by
hand until it is certain that the threads are properly
engaged.
4b. Then using two wrenches tighten the coupling
until it bottoms out or a definite increase in
resistance is felt.
It is important that ONLY the nut on the
pre-charged tube be turned, or the diaphragms will

be torn out by the piercing knives and they will be
loose in the refrigeration system. Note: As the
couplings are tightened, the diaphragms in the
quick connect couplings will begin to be pierced. As
that happens, there will be some resistance to
tightening the swivel nut.
4c. Continue tightening the swivel nut until it
bottoms out or a very definite increase in
resistance is felt (no threads should be showing).
5. Use a marker or pen to mark a line on the
coupling nut and unit panel. Then tighten the
coupling nut an additional one-quarter turn. The
line will show the amount that the nut turns. Do
NOT over tighten.
6. After all connections have been made, and after
the king valve has been opened (do not open yet),
check the couplings for leaks.
