pneumatic) regulators option is installed. See
4.6.4.2 Electronic Pressure Control Utility for instructions on
using the E/P option.

4.6.2 Adjusting the Main Air Pressure
1. Verify that the facility air is connected to the main air pressure regulator inlet (Figure 4-4).
 For accurate pressure adjustment, lower the pressure below the desired level and then
increase to the desired pressure.
2. Rotate the knob on the main air pressure regulator counterclockwise until the main air
pressure gauge registers 0 psi.
3. Rotate the knob clockwise until the main air pressure gauge registers 90 to 100 psi
(621 to 689 kPa).
4. If the main air pressure gauge fails to register pressure, verify that the dispensing system is
connected to the facility air source.
5. Monitor the main air 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.
