Pre-Charged Tubing Coupling Connections

September 2006 Page 17

Inspect couplings, wipe clean and lubricate

both parts with polyolester refrigerant oil.

Hand tighten to be sure threads are properly

engaged.

Use two wrenches and continue tightening the

couplings. As the diaphragms being to pierce,

the couplings will be harder to turn. Be sure

only the swivel nut is rotated.

Continue tightening until the swivel nut feels

like it is tight, then go to the next step. No

threads will be seen when the couplings are

tight.

After the swivel nut feels like it is tight, mark

the nut and the panel. Then tighten one

quarter turn more. That ensures that there is

a brass-to-brass joint inside the coupling.
