4.12 Response in case of warnings and error messages ________________________
The Vacuklav
®
23-B has safety features as well as an extensive checking and monitoring system which is
integrated into the computer control. These functions guarantee a maximum of possible reliability for the
sterilization process, and eliminate risks arising from the autoclave for the patient and the autoclave operator.
For example, the system continuously tests a number of autoclave functions (for example, the sensor systems for
pressure and temperature) after the power switch is turned on. The autoclave system also checks to make sure
that further conditions are met for successful program start: For example, that power and water are present in
sufficient quantity and quality. Start of the program is not possible if these conditions are not fulfilled.
After the initial test, and after the program starts, the system will monitor all parameters relevant for sterilization, as
well as additional limit values for the individual program phases. If these limit values are exceeded, the system will
display the respective error messages and will automatically interrupt the program.
In addition to instructions, warnings, and error messages on the display, the printer (if connected) will log out the
type of errors and faults, and the time of their occurrence.
If any of the above-stated messages appear, please read Section 7 of this manual for appropriate reactions. This
section also contains instructions concerning possible operator faults.
4.13 Operational
shutdowns
___________________________________________________
If the autoclave is not being used for a certain period of time (for example, overnight), leave its door slightly open
rather than closing it. This will spare the door gasket and will lengthen its service life (e.g., by preventing it from
sticking shut).
In case of longer inactive periods – such as vacations – shut off the supply of water from the water treatment
system.

Placing the autoclave out of operation / transport / putting the
autoclave back into service
If you wish to take the autoclave out of operation, or if you wish to transport it, please proceed as follows:
Pull out the power plug. Allow the autoclave to cool down.
Drain both chambers of the water supply tank (see Section 2.8). Or, if you have a direct connection to a water-
treatment system, shut off the supply of demineralized / distilled water from this system.
Disconnect the hoses on the rear of the autoclave if you are using a water-treatment system (external water
supply).
If you are transporting the autoclave with its tray racks and trays still inside, protect the surface of the door
window by inserting a layer of foam rubber or other suitable material (e.g., bubble wrap) between the door and
the sterilization chamber.
Important: To prevent transport damage, be sure to use the original packing of the autoclave. If there
is a danger of frost damage during transport, be sure to follow the steps provided in the special
service instructions.
To place the autoclave back into service after transport or repair, follow the instructions given in Sections 2
and 3 of this manual.
