Setup Leak Function on Heise Gauge
Introduction
The purpose of the leak isolation kit is to help find a leak in a sterilizer by isolating the chamber drain, steam to
chamber, and transducer piping. The leak isolation tool uses the sterilizer’s vacuum source to pull a vacuum on the leak
isolation test kit’s piping, the chamber drain piping, the steam to chamber piping, and the transducer piping. Using the
ball valves on the tool, the piping sections can be isolated to help determine the source of the leak.
NOTE: The leak isolation tool does not pinpoint the exact component that is causing the leak; it just shows which piping
assembly has a leak. If the leak is not in the chamber drain, steam to chamber, and transducer piping, then it will not
show up while using this tool.
Figure 1-1 shows the leak isolation kit connected to a sterilizer.

Wear proper PPE and follow LOTO procedure for the steam supply and all safety procedures.
1. Open door and insert safety pins.
2. Turn off the steam and electric to the sterilizer and use LOTO. Allow chamber to cool.
3. Install the correct Rubber Port Plug and washers onto the drain plug adapter shaft. Make sure the lock nut is
tightened all the way to the end of the threads, but do not over tighten.
4. Install the correct Rubber Port Plug and washers onto the Transducer plug adapter shaft. Make sure the lock nut
is tightened all the way to the end of the threads, but do not over tighten.

Analyzing the Results Obtained from Previous Tests
1. Compare the decays from the drain port, the transducer port, and the steam piping. If done properly, the piping
section with the largest decay is most likely the source of the leak.
2. Repair leak and repeat the test to verify that the leak is fixed.
3. After the leak has been repaired, air break the system, disconnect and remove all testing components, and
return the sterilizer normal operating condition.
NOTE: When the plug adapters are not in use, loosen the wingnut to take the pressure off the rubber plugs and to
prevent the rubber plugs from getting deformed.
