Lexa PLUS | Instructions for Use | RIS-311 ENG Rev03 | 29/08/2022 | © W&H Sterilization Srl

Open the chamber door, extract the tray using the tray holder and take the test
pack. The test pack can be wet outside.

CAUTION!

Risk of burns. The test pack is very hot at the end of the cycle. Wear

appropriate PPE (e.g. gloves).

Remove the indicator sheet from the center of the test pack and check the change
in colour. See "Bowie and Dick test" on page 45

Note

: for interpreting the test result follow the instructions of the PCD manufacturer.

Vacuum test

CAUTION!

Follow local/national guidelines on the frequency of testing.

Notice

: If a drainage period of the Unwrapped cycle is still operating, wait the drainage to be finished and the sterilizer to be both cold and dry.

Otherwise, a false negative outcome could occur.

PURPOSE OF THE TEST

The test is used to validate the sterilizer performance in terms of:

efficiency of the vacuum pump

tightness of the pneumatic circuit

DESCRIPTION

It consists of a vacuum phase, followed by a stabilization period of 5 minutes and a testing period of 10 minutes. The internal pressure is
monitored during the testing period. The pressure rise must be less than 0.013 bar (0.19 psi).
