Coupling Instructions

The couplings on the ends of the pre-charged line sets are self-sealing when installed properly. Follow these instructions carefully.

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.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 1/2" 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 1/2" discharge line goes to the ice maker fitting marked “discharge line”.

•The 3/8" liquid line goes 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 receiver valve has been opened (do not open yet), check the couplings for leaks.
