12. Autoclaving

This instrument is autoclavable at 121 °C (250 °F),
2 bar absolute (30 psi) with a holding time of at
least 15 minutes according to DIN EN 285. It is
up to the user to verify the effectiveness of the
sterilization.
1. Clean the instrument thoroughly
(see chapter 10).
2. Pull off the closure cap (10) and intake tube
(11).
Important!
Before the instrument is ready for
autoclaving, unlock the volume adjustment
lever, slide up to 20% of the nominal
volume and lock the volume adjustment
lever in this position. Then gently life the
piston in a slow and steady motion up.
3. Place the dispenser in this position together
with the closure cap and intake tube on a
towel into the autoclave. Avoid contact with
hot metallic surfaces.
Attention!
After autoclaving, allow the instrument
to slowly cool down to room temperature
(cooling time approx. 2 hours). Check all
parts for deformations, cracks and leaks.
