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 serve technician can be
requested by either calling your dealer or Tuttnauer USA.
9.1.1 Daily
Clean 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 models replace the air filter, every 6 months, or as
needed (see sec. 9.2).
3. Replace the door gasket every 12 months, or as needed
(see sec. 9.5).
4. Once every six months clean the fan grid with compressed
air from the inside outward.
5. Clean strainer once a month as per sec. 9.8. Cleaning
frequency may be reduced according to previous
maintenance.
