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.

Physical Checks
1.
Check that the PSI rating
on the valve matches
MAWP (maximum
allowable working
pressure) on the plate
welded to the kettle.
2.
Check that the Safety
Valve has a "UV" stamp.
3.
Check that the valve is
not damaged in any way.
If any of the above criteria
is not met, replace valve.

G/ CALIBRATING PROCEDURE
1.
Kettle must be empty when this procedure is executed.
2.
Insure the unit has a vacuum before you begin calibrating procedures. If unit
requires venting see REFERENCE SECTION (KETTLE VENTING
INSTRUCTIONS).
3.
Turn kettle ON and set temperature dial to 10 (Max.).
4.
Allow the unit to cycle twice (the green light must go on and off).
5.
Check temperature of the inner kettle surface with a digital surface thermometer.
For accurate readings move probe around bottom of kettle to locate the hottest
location.
6.
Temperature should be between 260° F and 265° F. Pressure gauge should read
between 20 - 28 PSI.
7.
Using a screw driver adjust temperature by turning the potentiometer on the
black box. Turn very little. Turn clockwise to INCREASES and counter-clockwise
to DECREASE temperature.
8.
Allow the unit to cycle twice.
9.
Re-check temperature.
