CALIBRATING PROCEDURE

1.Insure the unit has a vacuum before you begin calibrating procedures. If unit requires venting refer to Kettle Venting Instructions on page 18 of this manual.

2.Turn kettle ON and set temperature dial to 10 (Max.).

3.Allow the unit to cycle twice.

4.Check temperature of the inner kettle surface with a digital surface thermometer.

5.Temperature should be between 260° F and 265° F.

6.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.

7.Allow the unit to cycle twice.

8.Check temperature of the inner kettle surface with a digital surface thermometer.

9.Repeat steps 4 through 8 until unit is calibrated.

PRESSURE RELIEF VALVE PERIODIC TESTING PROCEDURE

WARNING: IMPROPER REFILLING OF

KETTLE JACKET WILL RESULT IN IRREVERSIBLE DAMAGE TO UNIT.

Most insurance agencies require periodic testing of pressure relief valves used on pressure vessels. This procedure will allow you to safely and quickly test your kettle's pressure relief valve. We recommend this test be performed twice a year.

NOTE: The following instruction is intended for use by qualified service personnel.

WARNING: Kettle surface will be hot and steam will be released during testing. Take necessary precautions including the use of gloves and eye protection to prevent personal injury.

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.With the kettle empty, turn unit ON and set temperature control to 10 (Max.). Allow the kettle to heat until the unit cycles off.

3.Switch unit OFF and disconnect main power at fused disconnect switch.

4.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.

5.Replace guard bracket from pressure relief valve/gauge assembly.

If valve appears to be sticking replace pressure relief valve.

If foreign material is discharged then drain kettle and replace pressure relief valve.

See Reservoir Fill Procedure (page 18) for full instructions on the correct method for refilling kettle jacket.

WARNING: Improper refilling of kettle jacket will result in irreversible damage to unit.

NOTE: Rust inhibitor is purchased locally. Read directions and do not exceed manufacturer's recommendation (excessive rust inhibitor can also cause solidification).
