7.3 Evaluation of Device Test ResultsAfter the test is completed, the Vacuum Indicator will automatically display the first result (blockage). Todisplay the other results press the TEST-Button once for each test. If you continue pressing the button afterthe 4th test result has been displayed, the earlier results will be repeated (Test 1,2,3,4,1,etc.). To exit thetest program, set the Operating Knob to another position.Test No. The programhas tested forBatteryindicator Test result indication Action if test failedTest 1 Blockage in theSuction System(includingcanister andtubing)LED #1 lit up Test Passed <100 mmHgFAIL100 mmHgPASSCheck possible blockages (e.g.twisted tubing, blocked filter,blocked filter in the liner) andrun the Device.Test again.If the High Efiiciency FiltrationKit is installed the pass limit is150mmHgTest 2 The vacuumbuild-upefficacy of thePump System(How muchvacuum is builtup within 3seconds)LED #2 lit up Test Passed >300 mmHgPASS300 mmHgFAILCheck Connectors, Tubes andCanister Lid for leakage* ordamage.Check exhaust outlet forocclusion and run the DeviceTest againTest 3 The maximumachievablevacuum levelof the LSU(reaches thislevel within 10seconds)LED #3 lit up Test Passed >500 mmHgPASS500 mmHgFAILCheck Connectors, Tubes andCanister Lid for leakage* ordamage.Check exhaust outlet forocclusion and run the DeviceTest againTest 4 Air leakagesin the PumpSystem(includingcanister andtubing)LED #4 lit up Test Passed >450 mmHgPASS450 mmHgFAILCheck Connectors, Tubes andCanister Lid for leakage* ordamage and run the DeviceTest again* If it is not obvious where the system is leaking; go step by step through the connections. Start by disconnectingthe Vacuum Tube at the Canister and run the Device Test (blocking the tube). Reconnect the tube anddisconnecting the patient tube, run device test (block the PATIENT inlet on the Canister). Continue with otherconnections until the leakage is identified.Note: If the LSU does not pass one or more of the steps in this test after suggested actions are taken, thedevice might need to be returned for service (see the Troubleshooting guide).English20
