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 on page #27).

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.

1.Remove guard bracket from pressure relief valve/gauge assembly.

2.Set On-Off Switch/Temperature Control to to "10 " (Max.), heat the empty kettle until unit cycles off.

3.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.

4.Set On-Off Switch/Temperature Control to to "0" (Max.). 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.

Remove,clean threads, apply teflon thread sealant

and reinstall.

2.Pressure Relief Valve

A/ Inspect for signs of leaks. Replace if required.
