Connecting the Servo Air for the Gas Sampling Valve

Connecting the Servo Air for the Gas Sampling
Valve
The connection of the servo air supply for the gas sampling valve is schematically
shown in Figure 4-6.
Use the following procedure to connect the servo air to the GC inlet manifold
when the GC is equipped with the gas sampling valve.
1. Make sure the air supply is turned off.
2. Connect the air line to the Servo air inlet with 1/8-in. Swagelok fittings.
NOTE If the GC has been furnished with a 2x1 mm tube, use the ferrule for 2x1mm/1/8-in
provided in the start-up kit.
WARNING! Pressure of the servo air supply line should be set to a maximum of 500 kPa (72 psi).
