The following venting procedure should be followed when the Vacuum/Pressure Gauge needle is in the "VENT AIR" zone:

NOTE: Check for and eliminate leaks prior to venting (See Repairing Leaks in Steam Jacketed Kettle Fittings.

DANGER: PRESSURE RELIEF VALVE WILL EXHAUST HIGH TEMPERATURE STEAM. CONTACT WITH SKIN COULD RESULT IN SERIOUS BURNS. KEEP FACE,

HANDS AND BODY CLEAR OF DISCHARGE.

DANGER: WORKING ON MACHINES

WITH POWER COULD RESULT IN

SEVERE ELECTRICAL SHOCK.

LEAK TEST PROCEDURE:

1.

Heat kettle until unit cycles off.

2.

Shut off power to the kettle at the fused disconnect

 

switch.

3.

Spread Bubble Type Leak Detector over suspected

 

areas and watch closely for bubbles.

1.Turn kettle ON and set Temperature Control to 10 (Max.), heat the empty kettle until unit cycles off.

2.Vent kettle by pulling safety valve ring 8-10 times in short 2-3 second blasts with a 5 second interval between pulls.

4. Repair areas as required.

REPAIRING LEAKS IN STEAM JACKETED KETTLE FITTINGS

If unit will not hold a vacuum the most likely cause is a leak at one of the fittings.

Often, the easiest way to eliminate a leak is reseal the suspect areas.

NOTE: If unit cycles ON, stop venting and wait for kettle to cycle OFF before continuing.

3.Turn kettle OFF. Add cold water to kettle until its surface temperature is below 100°F. The pressure gauge needle should be in the green zone, indicating a vacuum in the kettle’s jacket.
