Procedure
Change the Purge Time to zero
Change the Vacuum Time to 15 minutes
Once the cycle has progressed into the third PreVac, remove the fuses from the steam to jacket and the steam to chamber relays
When the cycle progresses to the Heat Chamber phase, first remove the fuse from the drain relay and then remove the fuse from the vacuum system relay
After 20 minutes of the cycle being in Heat Chamber, it will go into steam to chamber retarded
Install all the fuses that were removed and advance the cycle
Compare the pressure at the point were the cycle went to Heat Chamber and the point where the cycle went into Alarm. See if there was any vacuum lost
If there was more than .7 inches lost, there is a leak somewhere that needs to be fixed
Possible Sources of Air Leaks
The leak could be from:
- Check valve
- Solenoid valve
- Leaking gasket
- Loose fitting in the plumbing
Once the leak has been found, fix the problem and re-run the vacuum leak test
