CHAPTER 4. OPERATION
PLEASE CHECK CHAPTER 3 FIRST (if not done already)
Remark:
At the end of a cycle, the unit emits two different acoustic signals:
1) Acoustic signal for DRYING PHASE is a row of beeps in short succession.
2) Acoustic signal for COMPLETION is a continuous beep of 40 seconds.
When the drying buzzer sounds, open door slightly in order to achieve a perfect drying result.
CAUTION
1. BEFORE OPENING THE DOOR ENSURE THAT the pressure gauge shows “zero”.
2. ALLOW THE UNIT TO COOL OFF FOR a minimum of AT LEAST 20 MINUTES in between
cycles.

CHAPTER 4 OPERATION
1. Open the door and put the products to be sterilized on the trays or sterilization box, or
spring holder, etc. Then, push the power switch ON.
We recommend to put sterilization indicator stripes with the products to get an
additional confirmation of a good sterilization result.
2. Close the door and turn the door handle 90° to latch the door completely.
3. Set-up the programs as your protocol requires, i.e.
•121°C （1.2 bar) or 135°C（2.2 bar)
•WRAPPED or UNWRAPPED /DRY or UN-DRY
Please refer to APPENDIX A for more information on programs.
Reminder:
When choosing the “LIQUID” program, no other parameters can be set, this is a
fixed program for liquid sterilization use only.
•Sterilization temperature: 121°C
（
1.2 bar)
•Sterilization time: 40 minutes
•No Dry and Exhaust function in this program.
4. Push the START key, then the autoclave will start working and run the set program
automatically.
5. The autoclave will sound an acoustic alarm once the sterilization cycle is complete. Make
sure that the green light indicator above COMPLETE is illuminated. If not, the
sterilization cycle has failed and needs to be repeated.

CHAPTER 5. REMINDERS, WARNINGS & CAUTION
1. USE DEDICATED POWER ONLY. See technical data sheet
2. Please check the pressure gauge prior to opening the chamber door.
Don’t open the door if gauge indicates more than “ZERO” If you have a
vacuum indication, please use the Vacuum release key to equalize pressure
before attempting to open the door. This will prevent damaging the door
gasket.
3. USE ONLY DISTILLED WATER. Warranty is voided when other liquids such
as tap water are used.
4. When locking the door for operation, the door handle must be turned completely
to the stopping point.
5. Warning, during operation the top portion of the housing might be hot.
6. We recommend the use of biological indicator strips as a check for sterility. These
strips may also be kept as a record of sterilization.
7. In the event of an emergency or maintenance, please turn-off the main power
switch and disconnect the unit from power supply immediately.
8. Do not fill the water tank over its capacity, check indicators min/max
9. When the ADD WATER indicator light is on, the chamber is being supplied with
water. Please don’t confuse this with the low water indication.
10.If the “DOOR” Indicator light is on, the door has not been closed completely.
11.If the “LOW WATER” indicator light is on, the water level in the water reservoir
needs to be checked, please proceed as follows:

Page 18 of 25
CHAPTER 5. WARNING & CAUTION
a) If the level in the water reservoir is not sufficient, please add water. In order to prevent
overflow of the water reservoir, please consider the water amount already in the
chamber which will be pressed back into the reservoir after sterilization.
b) If the water level is OK then either the chamber level- or the reservoir level-sensor
might be dirty or has a contact problem. Please clean the surface of either sensor and
try again. If the indicator light is still on, please call our technical support to
troubleshoot.
13. If the !DANGER (OVER HEAT / PRESSURE ) indicator light is on, there is a
problem with the heater or pressure or both. The autoclave will shut down immediately. In
addition please pull out power plug and call technical support to check your unit.
14. Always keep chamber -collar and -gasket clean to prevent steam leaking from the unit
and jeopardizing the sterilization process.
15. Don’t forget to ensure that the sterilization stripes show SUCCESS after sterilization.
16. Reminder:.In order to assure a long life time of your SterilElite, read and make sure you
follow the check-list in CHAPTER 8. MAINTENANCE REQUIREMENTS.
