Figure D–6: 6-mm stud
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 650 to 750 kPa (6.5 to 7.5 bar, 94 to 109 psi).
D.4 Connecting the source exhaust line
Required tools and materials
• Chemical-resistant, powder-free gloves
• PTFE tube cutter
• 12-mm PTFE tubing (included in the installation kit)
Warning:
To prevent exposure to biologically hazardous, toxic, or corrosive LC solvents, the
source exhaust line supplied with the system must be either fed into a ducted laboratory fume
hood or connected to a laboratory exhaust system. The source exhaust line must be vented in
such a way that the pressure at the outlet never exceeds atmospheric pressure to ensure the
correct functioning of the API source pressure monitoring system.
Warning:
To avoid the buildup of hazardous gases, do not place the nitrogen exhaust
trap bottle in an enclosed cabinet.
Notice:
The instrument requires two separate exhaust systems: one for nitrogen, the
other for the backing pump. Vent them to atmosphere through separate exhaust lines.
Oil mist can seriously damage the instrument if the nitrogen exhaust line connects with
the backing pump exhaust line. Your warranty does not cover damage caused by
routing exhaust lines incorrectly.
Notice:
To avoid gas leaks, use the tube cutter to cut the PTFE tubing squarely.
To connect the source exhaust line:
1. Position the exhaust trap bottle in an accessible area below the instrument.
