To connect the system to the facility air supply:
CAUTION! Make sure that facility air pressure meets the requirements, see 9.2 Facility
Requirements. Higher pressures will damage the dispensing system.
1. Locate the facility quick-disconnect air hose.
2. Make sure each dispensing system main air regulator is closed. Verify facility air pressure is
at 0 psi.
3. Connect the facility air hose(s) to the quick-disconnect(s) on the main air regulator(s).
4. If not already connected, also connect the air hose(s) to the facility air supply (Figure 3-14).

3.14 Adjusting the Main Air Pressure
The main air inlet provides regulated air pressure to the dispensing system from your facility air source.
You can adjust the main air pressure with the main air regulator.
To adjust the main air pressure (Figure 3-16):
1. Verify that the facility air is connected to the main air pressure regulator inlet.
2. Locate the main air regulator at the rear of the dispensing system.
3. Rotate the main air regulator counterclockwise until the main air gauge registers zero (0).
4. Rotate the knob clockwise until the main air pressure gauge registers 621 to 689 kPa
(90 to 100 psi).
For accurate pressure adjustment, lower the pressure below the desired level and then
increase to the desired pressure.
5. If the main air pressure gauge fails to register pressure, verify that the dispensing system is
connected to the facility air source.
If there is an air leak, identify the source, shut off the
facility air, and fix the leak before
proceeding.
NOTE The regulator assembly is equipped with a relief valve to protect the system components.
Increasing the pressure above 655 kPa (95 psi) may trigger the relief valve. If so, reduce
the air pressure below 655 kPa (95 psi).
