6.2 Automatic Water Filling
6.2.1 For new units 2340, 2540, 3140, 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 overflow 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.
6.2.2 For units 1730 & any unit with serial number prior to 2003000
If it becomes necessary to adjust the automatic fill, follow these
steps:
1. Make sure the power is off.
2. The door should be open and the chamber empty of any water.
3. Make sure the Water Electrode is clean (see sec 9.10).
4. Press and hold the Water Inlet key (this is the button on the
keypad with the two arrows).
5. Turn the power on. When the program display screen appears,
release the Water Inlet key – wait one second and press it in
again.
6. Water will begin flowing into the chamber.
7. Monitor the water flow.
8. Hold the Water Inlet key until the water reaches the groove at
the front of the chamber.
9. Release the button – wait ten seconds – the unit is now
reprogrammed.
