Sea Frost DC 5000 installation instructions Reconnecting Pre-Swagedfittings

STEP 2

Before tightening the SWAGELOK nut, scribe the nut at the six o'clock position.

STEP 3

Now, while holding the fitting body steady with a backup wrench, tighten the nut 1 1/4 turns. Watch the scribe mark, make one complete revolution and continue to the 9

o'clock position. By scribing the nut at the 6 o'clock position as it appears to you, there will be no doubt as to the starting position. When tightened 1 1/4 turns to the 9 o'clock position, you can easily see that the fitting has been properly installed.

* SWAGELOK FITTINGS ARE TO BE TIGHTENED TO A TORQUE SPECIFICATION NOT INFINITE TIGHTNESS. BE SURE YOUR STARTING POINT IS WRENCH SNUG. A DISTORTED TUBE MIGHT GIVE A FALSE STARTING POINT.

*When making all connections, USE TWO WRENCHES. Don't allow the fittings to turn or twist when tightening.

*Be sure the fitting nut is not cross threaded! Cross threading will ruin the fitting. The fittings on the V/U cannot be replaced; as a result cross threading will ruin the V/U.

RECONNECTING PRE-SWAGED FITTINGS

Connections can be disconnected and re tightened many times.

When reconnecting, insert the tubing with pre-swaged ferrules into the fitting until the front ferrule seats in the fitting. Tighten the nut by hand to avoid cross threading. Rotate the nut about one-quarter turn with a wrench (or to original one-and-one-quarter tight position). Then snug slightly with the wrench.
