- After installing switch, run a 15 amp AC ammeter in power supply
line. As alternate, run a 120-volt voltmeter across the center heating
element terminals
- Starting from a cold condition, run a normal autoclaving cycle
- Remove temperature control knob on front of machine and rotate
shaft to maximum position (turn clockwise)
- Current should be on when machine is at 270°F (27 PSI). If not,
turn adjustment screw in overheat thermostat switch counter-clockwise
to restore current. Safety valve should have released if
pressure goes to 35 PSI
CAUTION - DANGEROUS IF PRESSURE EXCEEDS 35 PSI
- At 270°F (27 PSI) turn screw clockwise until current is off (0 reading
on meter used in #1 above). Then carefully turn screw counterclockwise
until current starts up. Setting is now proper for switch if
autoclave was started cold
- The switch is now set and needs no further adjustment. Return to
the temperature control shaft (#3 above), turning it counter-clockwise
until it is set at 270°F (27 PSI). The knob can now be replaced
- See the service manual for adjusting instructions
