9.11 Replacing the water pump
The water pump supplies mineral - free water to the jacket of the
autoclave from the front compartment of the reservoir. This water is
used by the steam generator to produce steam for sterilization.
The pump is protected from running dry and burning out, by the float
switch mounted in the lower part of the front reservoir compartment.
Caution!
Before starting, disconnect the instrument from the power source
and ensure that there is no pressure in the autoclave’s chamber
and jacket.
1. Take off the autoclave cover (see para. 9.2 “Removing the
Autoclave’s Outer Covers”).
2. Disconnect the wires from the pump
3. Empty the water reservoir, by using the drain value on the front of
the autoclave.
4. Disconnect the piping from the pump.
5. Remove the pump from the rubber shock absorbers. (If the rubber
shock absorbers are damaged, replace them also).
6. Replace the damaged pump with a new pump.
7. Reconnect wiring and piping.
8. Turn on the autoclave and verify it operates correctly and none of
the connections are leaking
9. Reassemble the cover.
