How To Adjust The Vernitron Autoclave Temperature Regulator



The Vernitron Autoclave Sterilizer has been factory set at sea level, to obtain a maximum temperature of 272°F. The maximum temperature will decrease approximately 1°F per 1000 feet increase in elevation above sea level.

The maximum temperature can be adjusted as follows:
  1. With the sterilizer operating at maximum temperature (regulator knob turned counter clockwise) loosen set screw in temperature regulator knob, using a 5/64 Allen key. Remove knob from temperature regulator shaft by pullingknob straight out.
  2. Using a straight screw driver, rotate the temperature regulator shaft counter clockwise until the HEAT ON indicator lights. When the HEAT ON indicator goes out, observe the maximum temperature.

    If the maximum temperature is below 272°F, rotate the temperature regulator shaft counter clockwise as above. Continue this procedure until the maximum temperature (the point at which the HEAT ON light just goes out) is 272°F.

    The minimum temperature (the point at which the HEAT ON light just comes on) will be approximately 270°F. The maximum temperature of the sterilizer is now properly set.
  3. Replace the temperature regulator knob with the white indicator pointing up in the 12 o'clock position. Tighten set screw.
