Installation
1.
Select either the 6 mm (¼ in.) or 12 mm (½ in.) fitting as appropriate.
2.
Insert the tube adapter into the tube fitting. Make sure the tube adapter rests firmly on the shoulder of the tube
fitting body and the nut is finger tight.
3.
Mark the nut at the 6:00 position.
4.
While holding the fitting body steady, tighten the tube nut 1 ¼ turns to the 9:00 position.
5.
Use a gap inspection gauge, placing it between the nut and the body. If the gauge enters the gap, additional
tightening is required.
Refer to Swagelok’s manufacturer instructions.

Enclosure purge outlet
For systems with the optional sample system enclosure purge,
1.
For systems with an enclosure, open the enclosure door.
2.
Set the pressure gauge (1) to 69 to 103 kPa (10 to 14.9 psi).
3.
Set the flow rate to 1 liter per minute and run the purge for at least 4 minutes for safety, and until the moisture
reading is below an acceptable error level.
4.
Change the sample supply (2) valve to flow gas.
5.
Position the validation/sample gas to open.
6.
Set the pressure gauge (1) to setpoint.
Do not exceed 172 kPa (25 psig) setting on the pressure gauge.
Do not exceed 345 kPa (50 psi) from the pressure reducing station.
For CRN systems: Do not exceed 103 Kpa (14.9 psi) setting on the pressure gauge.
