When properly adjusted, the valve permits maximum release of steam
pressure without causing violent agitation of the liquid.
Use care with the dial glass, when adjusting the jacket pressure gauge.
The dial glass is not fastened to the rim. When the rim is unscrewed,
the dial glass could drop out.
Remove the right side panel for access to the valve if the sterilizer has a
Close the valve finger tight, then open 1/4 turn.
(3) Adjust the valve so that it takes 10 to 15 minutes in the exhaust phase of
a liquids cycle to empty the chamber. Make the adjustment with an empty chamber.
(4) If sediment restricts the flow of steam through the valve, clean the valve
and readjust it.
c. Adjust the Jacket Pressure Gauge. Adjust the jacket pressure gauge if the
gauge does not read zero when there is no jacket pressure (unit is off and cool). Refer
to figure 1-18.
Figure 1-18. Jacket pressure gauge.
(1) Remove the top panel for access to the jacket gauge. The gauge is
located on the piping above the sterilizer body.
(2) Remove the dial glass by unscrewing the rim from the gauge case. Use
a strip of rubber to remove the dial glass to avoid hand pressure binding the rim.
