- Page 23 Message is displayed, if during a normal heat up stage the system determines that there is insufficient water in the chamber to complete the cycle. This determination is made by the combined input of two sensors, the Water Electrode and the Safety Thermostat. Also, if a power failure occurs during the heat or sterilization stage after the power returns, the system will check the Water Electrode to see if there is sufficient water in the chamber in order to resume the cycle.

Page 27: Printer (Optional)
PRINTER (Optional) The printer is an optional device. If the autoclave is not equipped with a printer, paragraph 5 is not applicable. Printer Operation The autoclave is equipped with a character printer that prints a detailed history of each cycle performed by the instrument (for the record or for subsequent consideration). - Page 28 PRINTER OUTPUT DESCRIPTION Autoclave No: 01 Number of the autoclave with respect to other units in the same location. Load number: 0005 Load number. Useful to determine when to clean the chamber. (Upon reaching 255, this number is reset to 0). Operator :___________ To be filled in manually by operator.

However, if in routine operation there is inadequate water in the chamber, the operator can adjust the level with the automatic built-in system by doing the following: Press STOP key repeatedly until the message “code xxx”... -
Page 32: Lifting And Carrying
Warning: If it becomes necessary to RESET the software program, it will be essential to repeat all steps listed above. This will ensure that the correct amount of water enters the chamber for operation. VERY IMPORTANT – Due to the fact that the water lines are empty when the unit is shipped, air may become trapped in the lines. -
Page 33: Filling The Water Reservoir
Filling the Water Reservoir Remove the 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). Use water-having characteristics as per table in sec 2.11 Caution: Under no circumstance should water be filled above the safety valve holder. -
Page 34: 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 35 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 36 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 37: Operating Instructions
OPERATING INSTRUCTIONS It is important to clean the hole of the air jet, as described in sec. 9.4 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 38 9. At the end of the cycle a buzzer rings for approximately 5 seconds, the START light switches OFF. The air outlet valve is opened to prevent formation of a vacuum. In the event of a program failure, the exhaust valve is opened to release pressure from the chamber and a continuous buzz will sound for 5 seconds followed by an interrupted buzz of 7 seconds.

Page 41: Replacing The Air Filter
Replacing the Air Filter To facilitate drying the instruments with the door of the chamber closed, the autoclave is equipped with an air compressor and HEPA filter (0.2 m). 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 42: 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 43: 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. -
Page 44: Replacing The Door Gasket
Replacing the Door Gasket Pull off the gasket from the door groove. Install the new gasket as described in drawings 1, 2 and 3 above. Caution! This gasket is designed with a trapezoidal cross section. The gasket should be placed with the widest side towards the door. -
Page 45: Checking The Safety Valve
Checking the Safety Valve (Located in the water reservoir) In order to prevent the safety valve from becoming blocked, it is necessary to allow the steam pressure to escape through the valve. This procedure should be done every month as follows: 1. -
Page 46: Replacing The Fuse
Replacing the Fuse Caution Make sure that the electrical power cord is disconnected! Use a screwdriver to unlock the fuse holder cover by turning it counterclockwise ¼ turn, and pull it out. Insert a new fuse into the holder and turn the cover clockwise until locked. -
Page 47: Cleaning Water Outlet Strainer
Cleaning Water Outlet Strainer Caution! Before proceeding, make sure that the electric cord is disconnected and there is no pressure or water in the chamber. Warnings 1. The strainer’s cover is HOT Do not touch the strainer’s cap, mounted on the exhaust line, during and shortly after operation. -
Page 48: Cleaning Tabletop Autoclaves With Chamber Brite
