Pressure Relief Valve Periodic Testing Procedure
1. With the kettle empty, set On-Off Switch/Temperature Control to "10"
(Max.). Allow the kettle to heat until the unit cycles off.
2. Switch On-Off Switch/Temperature Control to "0" (Off) and disconnect main
power at fused disconnect switch.
3. Stand to the side of the pressure relief valve discharge tube and pull
valve open for a maximum of one second. Repeat test three to four
times. Each time the mechanism should move freely and be
accompanied by a rapid escape of steam.
If valve appears to be sticking replace pressure relief valve.
If foreign material is discharged then drain kettle and replace pressure
relief valve.
