Priorclave Manual 27125322-EN Issue 2
through a standard cycle. When the process time has commenced check the reading shown by
the temperature display against that of the thermometer or recorder. Should there be a
disparity of readings in the order of that previously noted then it is likely that the
Temperature Controller is at fault and needs resetting.
If only negligible temperature disparity is apparent, however, and the steam pressure is still
varying from the expected value by the amount noted previously, then the pressure gauge is
probably faulty and in need of replacement.
The pressure gauge and control system fitted to Priorclaves are extremely reliable
instruments and as such are unlikely to produce false readings. Therefore it is more likely
that any deviation from the values given in the steam table is caused by incorrect air
purging etc.
Fitting a new Door Seal Gasket*
When it becomes necessary to replace the gasket, simply remove the old gasket by pulling it
out of the groove in the pressure door.
Using an abrasive pad clean out the groove and wipe away any residue with a cloth. Locate
the joint in the new gasket and press this part of the gasket firmly into the part of the groove
closest to the hinge, marked A on the diagram.
Find the opposite centre line of
the gasket and press firmly into
the point marked B on the
diagram, ensure that there is an
even amount of gasket each side
of points A and B. Press the
gasket into the points marked C,
again ensuring that there is an
even amount of gasket between
all 4 points.
Press the gasket into the four
points marked D. Finally press in
the remaining points taking care
not to cut the gasket on the
header ring. Once the gasket is
fully fitted smear the top surfaces
with high temperature silicone
grease if required, and smooth
out any lumps, applying pressure
in a circular motion around the
gasket.
With the new gasket properly fitted, locking the lid may at first be a little tight. Please note
however that the gasket will bed down considerably when the autoclave is first used.
Great care should be taken when fitting a door seal gasket as if this is carried out incorrectly
it can affect the door sealing and ease of operation. It is strongly recommended that this
work is carried out only by trained personnel.
