If a pump fails to detect a downstream occlusion, the device should be removed from
service and repaired. Perform the following steps at room temperature to ensure proper
operation of the downstream occlusion sensor.
1. Load and prime an administration set.
2. Start the pump at a rate of 125 ml/hr and run for 1 minute.
3. Fold and pinch the tubing just below the pump.
The "HI PRSS" message for HIGH PRESSURE should appear on the display, the
audible alarm should sound and the pump should stop.
