Operational & Maintenance Safety
When the temperature of the steam jacket reaches the value corresponding to
the dial setting, the thermostat switch opens. This turns off the heating indicator
light and causes the contactors to open, stopping the power to the heaters.
As soon as the thermostat senses that the kettle is cooling below the set
point, the thermostat switch closes, the heating indicator light comes on, the
contactors close, and the heaters come on again. On-off cycling continues,
keeping the kettle at the set temperature. This is why the heating indicator light
cycles on and off during normal operation. Every time the kettle is tilted, the tilt
cut-off switch interrupts the power supply to the heaters, so that the heating
elements will not operate while not submerged in the jacket water.
If steam pressure greater than 50 PSIG (3.5 Bar/345 kPa) is generated in the
jacket, the safety valve will open and relieve the excess pressure.
If the jacket water level gets too low before the heating elements overheat, the
high-limit control will open and shut off power to the elements until the kettle
cools.
Setting the operating thermostat dial to “O” shuts down the heating circuits.
Setting the power switch to the OFF position removes power from the control
circuits.
6. To Empty Kettle
TDB(C) KETTLES WITH CRANK TILT
To tilt the body of the kettle forward, turn the hand crank on the front of the
cabinet anti-clockwise. The body will stay in the position it holds when you stop
turning the handle. To return the body to the upright position, turn the crank
clockwise.
TDB(C) KETTLE WITH TILT HANDLE
The kettle is designed to be tilted in a controlled manner. Grasp the insulated
plastic ball firmly. Maintain a firm grip on the handle when tilting, while keeping
the kettle body in a tilted position, and when slowly returning the kettle body to
an upright position.
7. Power Failure
If the power to the unit fails do not attempt to operate the appliance until the
electricity supply is reestablished. When the power comes back on follow the
steps in “Initial Kettle Operational Readiness Check.”
WARNING
DO NOT STAND IN FRONT OF THE KETTLE
BODY WHEN TILTING IT. BE CAREFUL TO
KEEP HOT CONTENTS FROM SPILLING.
ENSURE PEOPLE ARE KEPT AWAY FROM
THE KETTLE WHEN EMPTYING THE KETTLE.
