Page 35: Loading And Unloading The Device
Loading and Unloading the Device 6.4.1 Safety Protective equipment, clothes and other safety instructions should be implemented in accordance with local and national regulations and/or rules! For proper sterilization - Do not overload the chamber. Only autoclavable products shall be used; please refer to the material or instrument manufacturer's instructions for sterilization of unknown materials or instruments. -
Page 36: Preparation Before Sterilization
1. Clean instruments immediately after use to remove any residue. It is recommended that all instruments be ultrasonically cleaned using Tuttnauer's CLEAN AND SIMPLE enzymatic cleaning tablets or other suitable solution. 2. After cleaning, rinse instruments under tap water for 30 seconds and pat or air dry to remove residual minerals. - Page 37 18. Do not stack pouches. It is recommended that a pouch rack such as the Tuttnauer POUCH RACK be used to insure proper steam penetration and adequate drying. Surfaces that are hidden because the items are being stacked will not be exposed to the steam and will not be sterilized.
- Page 38 21. If spotting is detected on the instruments, the first step would be to use an ordinary eraser to remove the spot. If there is no pitting under the spot then the spot was only dirt. Dirt spots on an instrument may be an indication that the autoclave needs to be cleaned or that the instruments were not adequately cleaned or dried.

Page 39: Operating Instructions
OPERATING INSTRUCTIONS It is important to clean the hole of the air jet, as described in sec. 9.3 before starting operation of the autoclave for the first time. 1. Remove water reservoir cover. Pour distilled water into the reservoir, through the opening on top of the autoclave, until it reaches the base of the safety valve holder, approximately 0.7 gallons (3 liters). - Page 40 8.1 To obtain better drying results from the E and EK models, during the dry stage open the door partially (as described below) at an angle of approx. 20-25 degrees. The heaters will be on at a lower power level and water vapor and humidity will be evacuated from the chamber efficiently.

Page 43: Replacing The Air Filter (Models Ea, Eka)
Replacing the Air Filter (Models EA, EKA) To facilitate drying the instruments with the door of the chamber closed, models EA and EKA are equipped with an air compressor and HEPA filter (0.2µm). During the drying stage the compressor draws air through the HEPA filter and forces the circulation of that air through the heated chamber to remove moisture from the wrapped instruments. -
Page 44: Draining The Reservoir
Draining the Reservoir Caution Before starting, ensure that the electric cord is disconnected and there is no pressure in the autoclave. The drain valve is located on the front left side of the autoclave after the door is opened. The function of the drain valve is to drain the water reservoir. -
Page 45: Cleaning The Air Jet
Cleaning the Air Jet (Located in the water reservoir.) A dirty air jet is the number one cause of failed spore tests The elimination of air from the sterilization chamber during heat up is critical to the proper operation of the autoclave. Failure of the air removal system will be responsible for incomplete sterilization, indicator strips that do not turn, failed spore tests and aborted sterilization cycles. -
