9 MAINTENANCE INSTRUCTIONS
9.1 Preventive and Scheduled Maintenance
The maintenance operations described in this chapter need to be followed,
as indicated, to keep the device in good working condition.
The instructions that follow can easily be carried out by the office
personnel and do not require a service technician.
Should the need arise, technical assistance or a service technician can be
requested by either calling your dealer or Tuttnauer USA.
9.1.1 Daily
1. Clean the door gasket with a mild detergent, water and a soft
cloth or sponge. The gasket should be clean and smooth.
9.1.2 Weekly
1. ONCE PER WEEK , clean the air jet. To ensure that the
temperature inside the chamber rises properly it is necessary
to keep the air jet clean. A dirty air jet will prevent indicator
strips from changing color and cause spore tests to fail. See
sec. 9.4.
2. Clean the water sensor in the rear of the chamber with a damp
cloth or sponge. Cleaning the dirt off the sides of the sensor is
more important that the tip (see sec 9.10).
3. Once per week clean and descale the chamber, copper tubes
and the reservoir using
Chamber Brite (see sec. 9.9).
4. Take out the tray holder and trays. Clean the tray holder and
trays with detergent or a non-abrasive stainless steel cleaner
and water, using a cloth or sponge. Rinse the tray holder and
trays immediately with water to avoid staining the metal.
Caution
Do not use steel wool, steel brush or bleach as this can
damage the chamber and trays!
5. Put a few drops of oil on the 2 door pins and door tightening
bolt.
6. Clean the outer parts of the autoclave with a soft cloth.
9.1.3 Periodically
1. Once every month clean and check the safety valve.
2. On EA and EKA models replace the air filter every 6 months,
or as needed (see sec. 9.2).

frequency may be reduced according to previous maintenance.
