Perform the following procedure to check function of the Impingement Air Valve and Flowmeters.
To check function of Impingement Air Valve and Flowmeters:
1. Locate the Impingement Air Valve and Flowmeters in the front cabinet of the dispensing
system (
Figure 4-9).
2. Open the Impingement Air Valve by turning the handle counterclockwise so that it is parallel
with the airline. Listen for leaks.
! If there is an air leak, identify the source, shut off the air valve, and fix the leak before
proceeding.
3. While monitoring the readouts on the Flowmeters, turn the Flowmeter Adjustment Knobs
counterclockwise until maximum airflow is achieved.
! The flow indicators should show an increase in airflow.
4. While monitoring the readouts on the Flowmeters, turn the Flowmeter Adjustment Knobs
clockwise to lessen the flow.
! The flow indicators should show a decrease in airflow.
5. Restore maximum airflow and open the dispensing system hood. Verify air is coming out of
the holes in the impingement heaters at each conveyor station.
! If air is not flowing out of the heater, check the pneumatic connections.
