Qualification Testing
Your sterilizer should be tested after sterilizer installation, malfunctions,
relocation, major repairs, and after sterilization process failure.
Qualification testing should be performed prior to placing the sterilizer in
service. If multiple cycle types are used, e.g. “Pouches” and “Packs” each
cycle type should be qualified. Qualification testing should include at least
one Biological Indicator (BI) (sometimes referred to as Spore Tests) and one
Chemical Indicator (CI). The test pack should be placed on the bottom tray
near the chamber door and performed with items routinely processed and
considered to be the most difficult to sterilize. Additional items should be
placed in the chamber along with the Biological Indicator and Chemical
Indicator so that chamber is fully loaded (don’t exceed the maximum capacities
listed in the tables under Guidelines for Loading” in this manual). Three
consecutive test runs for each cycle type tested, with negative results from
the BIs, and the appropriate readings from all physical monitors and chemical
indicators demonstrating complete sterilization, provide verification that the
sterilizer has been properly installed (or reinstalled after relocation) or
repaired to the manufacturer’s specifications and that it will function
effectively in the facility in which it is installed. All items processed
during qualification testing should be quarantined until the results of the
biological testing are available.

cycle type tested, with negative results from the BIs, and the appropriate
readings from all physical monitors and chemical indicators demonstrating
complete sterilization, provide verification that the sterilizer has been
properly installed (or reinstalled after relocation) or repaired to the
anufacturer’s specifications and that it will function effectively in the
facility in which it is installed. All items processed during qualification
testing should be quarantined until the results of the biological testing are
available.
Close drain valve.
Ensure that the drain valve is in the Closed position.
Before Operating the QuickClean
A) Clean unit and wipe out tank. “Clean by wiping with a damp soapy cloth and
rinse.”
B) Pour water into the bath so that it reaches the liquid level sensor, but do
not exceed the maximum fill level. Follow cleaning agent’s recommendations on
water temperature. Cleaning efficacy can only be guaranteed if the water
temperature is at least 70 F.
C) Add the required dose of cleaning agent. Follow cleaning agent and
instrument manufacturers’ recommendations for acceptable cleaners and
concentrations.
To accommodate for tank size round up the amount of cleaning agent to the
nearest 1 oz/gal, 10 ml/l or 10 gram/l.
D) Turn on the machine via the switch at the rear of the unit, just above the
power cord. The switch will then illuminate.
E) Run a Degas Cycle.
Connecting the power cord.
A) Plug the power cord into the main power connection located on the back of
your unit
B) Ensure your QuickClean ultrasonic bath is plugged into a 115 VAC fully
grounded outlet.
Degas Cycle
Degas
- Degas cycle will allow optimal ultrasonic activity by removing gases present in ordinary tap water.
- The time needed to degas the liquid will vary depending on the amount of gas present in the liquid and the quantity of water in the tank.
- A degas period of 5 to 10 minutes is recommended.
- During the degas cycle you will see bubbles of gas forming on the inside of the ultrasonic bath and slowly rising to the surface, when you no longer see these bubbles come to the surface you can end your degas cycle.
Running a Degas Cycle.
A) When the unit is powered on, when you change the solution or when the
liquid has fallen below the water level sensor you will receive the option to
degas your ultrasonic.
B) Prior to starting the degas cycle, remove all instruments and make sure the
unit is filled with liquid and the required dose of cleaning solution.
C) Place the lid on the ultrasonic unit.
D) Select the upper < YES to start the degas cycle. The screen below will
display
E) Once all the bubbles have come to the surface your degas cycle is complete.
F) Press the↵ left arrow SKIP to end the degas cycle. Your degas cycle will
NOT automatically stop when degassing has completed
Test Cycle
Run a test cycle by performing a “Foil” test to ensure that your system is
running properly.
Perform the “Foil” Test
Purpose: Used to determine the efficiency of an Ultrasonic Cleaner.
- Quarterly testing of the ultrasonic cleaner to assure that it is operating properly is recommended.
- Testing should also be performed whenever deterioration in the cleaner performance is suspected.
- This foil test is relatively easy to perform and will provide a permanent record for the future comparative evaluation of the ultrasonic cleaners performance.
Note: The foil test instructions can be found in your User Guide.
