2 Clave 23+ Instruction Manual v1.4
Thank you for choosing our steam sterilizer.
Prior to operating this device, please read the instruction manual carefully and follow all
installation instructions.
Regular maintenance:
If this symbol appears on the screen when the device is powered on or if it shows E88
on the sterilization report, please contact your dealer or local service company for a maintenance
service. This device requires regular maintenance. A symbol or error code E88 will be
displayed after 1 year of use or after a certain number of cycles, whichever comes first. This is
programmed into the maintenance screen.
The Clave 23+ is the same as a Clave 23 except it has a built in compressor that speeds up the
drying process. It also has a bacteria filter that requires replacement approximately every 3
months.
Use only distilled water with this device.
Do not re-use the used water from this machine.
Power on the unit with the door open. This will allow the unit to get a initial zero pressure
reading. The machine may not start a cycle and only beep when the start button is pressed if it
has a non-zero pressure reading on powering up.

4. Installation
* Ensure that the sterilizer is installed with 10cm (4”) ventilation space on all sides of the
sterilizer and 20cm (8”) on the top. The clearance required to open the door is 40cm (16”).
* The sterilizer should be placed on a level work table.
* Do not cover or block the door or any ventilation areas on the sterilizer.
* Do not install the sterilizer near a sink or in a location where it is likely to be splashed with
water.
* Do not install the sterilizer near a heat source.
5. Operation
5.1 Setup
5.1.1 Open the door and remove all of the inner contents.
5.1.2 Connect the power cord to an outlet of the appropriate voltage.
5.1.3 Power on. The switch is located on the right side of the cover. After turning on the
machine, the LCD screen will turn on and show the door position, water level, working
program, date, time, etc.
Distilled water tank requires water.
Used water tank is full.
Printer is disconnected if it is blinking.
Door locked.
Notice: Before using the sterilizer or when the low water level icon blinks, fill the
distilled water tank with distilled water.
The LCD screen will go into sleep mode if a button has not been touched for some time.
You can exit the sleep mode on the screen by touching any button.

8 Clave 23+ Instruction Manual v1.4
5.1.4 Filling the distilled water tank
Open the cover and fill the tank with distilled water. When you hear the beep signal, it
means that the water level has reached the maximum level. The icon will be
displayed. Please stop filling immediately.
The water level should not exceed this port.
5.2 Preparation of Sterilization Materials
For the most effective sterilization and to preserve the instrument and tools, please follow
the suggestions below:
* Arrange the instruments of different materials on different trays or with at least 3cm of
space between them.
* Always insert a sterilization paper or cloth between the tray and instrument to avoid
direct contact between the different materials.
* Arrange the containers (glasses, cups, test-tubes, etc) on one side or in an inverted
position to avoid water pooling.
* Don’t stack the trays one above the other or put them in direct contact with the walls of
the sterilization chamber.
* Always use the instrument tray handle.
* Wrap the instruments one by one or, if more tools have to be set in the same bag, verify
that these are made of the same material.
* Don’t use metallic clips, pins, or other similar things as this jeopardizes the
maintenance of the sterilizer.
* Don’t overload the trays over the stated limit (see Appendix 2).

circuit and overheating of the main transformer winding.
Action: Interruption of the power to the transformer. Contact a service person.
3. Safety valve: Protection against possible sterilization over pressure.
Action: Releases steam and restores pressure inside the chamber to a safe level.
4. Safety micro-switch for the door status: Informs the user if the door is incorrectly closed.
Action: Signal indicates that the door is not closed properly.
5. Thermal switch on chamber heating elements. Protection against possible overheating of
the chamber.
