Here is a simple test to determine if it is time to replace the Jet Air Valve On Your Tuttnauer Autoclave
- Refer To Table A Of The Tuttnauer Maintenance Guide and in a measuring cup, fill it with the amount of water indicated in the chart for your model , then pour the measured water into the chamber
- Bypass the FILL setting to manually run Sterilizer in STE Mode at 273 degrees F for 30 minutes for M units or 15 minutes for MK & Valueklave 1730MKV units.
After 30 minutes (or 15 minutes), shut off power, but leave MPV in STE Mode until chamber pressure is reduced to 0 psi and chamber has cooled (approx 15 minutes)
- Open Chamber Door, siphon water back into measuring cup, and measure the amount of water that was remaining in the chamber
- If remaining water is less than 50% of the original volume and no other leaks were detected, Replace Air Jet Valve (see replacement part chart below)
- If remaining water is greater than 50% and the pressure did not reach 28 PSI within the nominal times (See Table D Below), and no fault was found within the heating system, then replace the Air Jet Valve (see replacement part chart below)
