Coupling Instructions
The couplings on the ends of the
These steps must be performed by an EPA Certified Type II or higher technician.
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.Thoroughly lubricate the threads,
Clean and Lubricate Couplings
3.Position the fittings on the correct connections on the condenser and ice machine.
The 12“ discharge line (schrader valve end) goes to the remote condenser fitting marked “discharge line”.
The 3 8“ liquid line (schrader valve end) goes to the remote condenser fitting marked “liquid line”.
The “ discharge line goes to the ice maker fitting marked “discharge line”.
The “ liquid line goes to the ice maker fitting marked “liquid line”.
Note: The system charge is contained in the receiver tank of the ice machine. Only “holding" charges are present in the
Final Connections:
4a. Begin to tighten 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 in place, tighten each coupling.
Tighten Swivel Nut
It is CRITICAL that ONLY the NUT on the
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 nut until it bottoms out or a very definite increase in resistance is felt (no threads should be showing). Do NOT overtighten.
5.Use a marker or pen to mark a line on the coupling nut and unit panel. Then tighten the coupling nut an additional

6.After all connections have been made, and after the liquid line valve has been opened (do not open yet), check the couplings for leaks.
