9.5 Drain Valve Repair
There are two drain valves on the front of the autoclave. One drains the
mineral free water from the front section of the reservoir and the other
drains the vacuum pump water from the back section of the reservoir.
Caution!
Before starting, disconnect the instrument from the power source and
ensure that there is no pressure in the chamber or jacket.
Allow the autoclave to cool before removing outer covers.
9.5.1 Replacing the O rings
1. Open the manual drain cock on the front of the machine
and drain any water left in the reservoir
2. Continue turning the drain cock in a counterclockwise
direction. Some resistance will be felt, but eventually the
drain cock assembly will come out.
3. Replace the two O rings on the drain cock (see drawing).
4. Reinstall the drain cock in the drain valve body by
turning clockwise.
5. After a few turns press the large O ring (1) into the
recess on the drain valve body.
6. Continue turning clockwise until the drain cock is seated.
