Connecting to the nitrogen gas supply
Required materials
•
Chemical-resistant, powder-free gloves
•
Sharp knife
•
Wrench
•
6-mm PTFE tubing (included in the installation kit)
•
6-mm stud
•
Nitrogen regulator
To connect the nitrogen gas supply:
1.
Use the sharp knife to cut a length of 6-mm PTFE tubing long enough to connect the rear of
the instrument to the nitrogen regulator.
2.
Connect one end of the 6-mm PTFE tubing to the nitrogen inlet port on the rear of the
instrument (see
3.
Attach the nitrogen regulator to the nitrogen supply.
4.
Install the 6-mm stud into the regulator outlet.
5.
Connect the free end of the long piece of 6-mm PTFE tubing to the 6-mm stud.
Requirement:
The nitrogen must be dry and oil-free, with a purity of at least 95%. Regulate
the supply at 600 to 690 kPa (6.0 to 6.9 bar, 87 to 100 psi).
Requirement:
Wear clean, chemical-resistant, powder-free gloves when connecting the
nitrogen gas supply.
Notice:
To avoid gas leaks, use the sharp knife to cut the PTFE tubing squarely (that is,
perpendicular to its horizontal axis).
