6.2 Automatic Water Filling
6.2.1 For new units 2340, 2540, 3545, 3850 & 3870
The proper amount of water for automatic filling in your new
Tuttnauer autoclave has been preset at the factory. 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.
1. Press STOP key repeatedly until the message “code
xxx” appears on the display.
2. Use the UP or DN arrow keys to change the code to
105, then press the STOP key
3. A
message will be displayed saying “Water in = xx sec”
4. Press UP or DN keys to increase or decrease water
inlet time.
5. Press the STOP key to enter new water inlet time into
memory.
6. If necessary press the STOP key again to bring up the
program display.
Note:
DO NOT attempt to automatically fill the chamber with the
DOOR open. Water will over flow out of the chamber.
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.
