The Device Test is a user initiated test program to identify whether the LSU operates
satisfactorily or if it needs service. If the device is not in frequent use (i.e. less than once
a month), the Device Test should be performed both on a monthly basis and after each
Cleaning and Assembly process.
The program runs 4 different tests:
1. Occlusions - Blockages in the Suction System, including canister and tubing.
2. Vacuum efficacy - How much vacuum builds up in the Pump System within 3 seconds.
3. Maximum vacuum level - The maximum achievable vacuum level of the
LSU within 10 seconds.
4. Leakages - Air leakages in the Pump System, including canister and tubing.

Before Device Test Checklist:

• Ensure the LSU is correctly assembled and the Patient Suction Tubing is unwound.
• The Suction Catheter Adapter is removed from its holder (if applicable).
• Ensure the battery is not being charged (the device is not connected to
AC/DC power source).
Note
If you need to interrupt the test and revert to normal operation, turn the Operating Knob to
another position and then select the required setting.
