4.6.4 Adjusting the Cooling/Coaxial, Valve, and Fluid Air Pressure
4.6.4.1 Manual Regulator Adjustment
1. Locate the Cooling/Coaxial, Valve, and Fluid Pressure Regulator adjustment knobs in the
front cabinet (Figure 4-6).
 For accurate pressure adjustment, lower the pressure below the desired level and then
increase to the desired pressure.
2. Rotate the adjustment knob counterclockwise until the gauge registers 0 psi.
3. Rotate the adjustment knob clockwise until the associated gauge registers the air pressure
value (psi or kPa) required by your dispensing application.
 NOTE Pressure settings depend on the fluid being dispensed and dispensing valve
being used. Refer to the applicable dispensing valve manual for additional
information.
4. Monitor the pressure gauge to make sure that pressure builds at a steady rate. A drop in air
pressure can indicate an air leak.
 If there is an air leak, identify the source, shut off the facility air, and fix the leak before
proceeding.
