Coupling Instructions:
Initial Connections:
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
3.Position the fittings on the correct connections on the remote condenser
and ice machine.
●The 1/2 inch discharge line (Schrader valve end) goes to the remote condenser fitting marked “Discharge Line”
●The 3/8 inch liquid line (Schrader valve end) goes to the remote condenser fitting marked “Liquid Line”.
●The 1/2 inch discharge line goes to the ice machine fitting marked “Discharge Line”.
●The 3/8 inch liquid line goes to the ice machine fitting marked “Liquid Line”.
Final Connections:
4a. Begin by tightening the couplings together by hand. Continue to turn the swivel nuts by hand until it is certain that the threads are properly engaged.
4b. Using two wrenches, one to rotate the swivel nut and one to hold the tubing, tighten each coupling. It is CRITICAL that ONLY the NUT on the precharged tube be turned or
the diaphragms will be torn loose by the piercing knives and be loose in the refrigeration system causing severe operational problems.
Note: As the coupling is tightened, the diaphragms in the quick connect couplings will begin to be pierced. As that happens, there will be increased resistance to tightening the swivel nut.
4c. Continue tightening the swivel until it bottoms out or a very definite increase in resistance is felt (no threads should be showing). Do NOT over tighten.
5.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 the 1/4 turn is made.
6.After all connections are made, and after the king valve has been opened (do not open at this time) check the couplings for leaks.
