4-16 Operation
Gauges and Regulators
The C-721 has four types of gauges and regulators:
• Main Air
• Fluid
• Valve
• Conveyor
WARNING! Before you reach inside the dispensing system front doors, you must fully
understand the related Dispenser Status indicators, which have the same
meanings as the Beacon color indications in Table 3-3.
The fluid and valve regulator controls are black knobs extending down from the roof of the dispensing
area. To reach them you must open the front doors. The Main Air and Conveyor regulator controls are
located at the rear of the system (Figure 4-4). See detailed adjustment instructions following descriptions
of the gauge and the regulator.
