The TDB and TDBC are table top, tilting, steam jacketed kettles with an electroni-
cally controlled, self-contained, electrically-heated steam supply and appropriate
controls, mounted on a sturdy base. Models are available in 20, 24, 40 and 48
quart capacity.
The body of the kettle is constructed of stainless steel, welded into one solid piece.
The kettle is furnished with a reinforced rim and a butterfly shaped pouring lip.
It has a steam jacket rated for a design pressure of 50 PSIG. Kettle finish is 180
emery grit on the inside and bright semi-deluxe on the outside. A tilt handle on
the TDB kettle and a hand wheel crank on the TDBC kettle allows the operator to
manually tilt the kettle body in a controlled manner. Pouring height accepts pans
up to four inches high on a table top.
A built-in steam generator, sized for the kettle capacity and heated by electric-
ity, delivers steam into the jacket. “Airless” operation of the steam jacket permits
uniform, efficient heating at temperatures as low as 150°F and as high as 295°F.
In addition to the operating control, the unit has a tilt cut-off switch, low water
cut-off, pressure relief valve, and high-limit pressure switch as safety features. A
heating indicator light, pressure gauge, and sight glass are provided for monitoring
kettle operation.
A single electrical connection is required for installation. The unit may be ordered
for use with 208/240 or 480 volt power. All 208/240 volt kettles are wired for 208

the product since only the tip of the core probe senses the product
temperature. Do this by inserting the core probe halfway into the product,
positioning the tip at the center of the food mass, avoiding any bones.
If placing into a semi-liquid or liquid product, occasionally stirring the
product will ensure an accurate core probe reading. Do not let the core
probe tip touch the edges, bottom or side of the unit.

3. To Transfer Product or Empty Kettle
a. TDB: The kettle is designed and manufactured to be tilted in a controlled
manner. Grasp the insulated plastic ball firmly. Maintain a firm grip on
handle when tilting, while keeping the kettle body in a tilted position and
slowly return the kettle body to an upright position. DO NOT release
handle when kettle is partly tilted. It will impact in either the upright or
fully tilted position and may cause burns.
b. TDBC w/ STD Control: The kettle is tilted using its crank tilt hand wheel.
Turning the crank clockwise tilts the kettle; counter-clockwise returns it to
an upright position. The kettle will remain in any cranked position.
Lift the rear of the lid first.
USE OF COMMON ACCESSORIES
1. Lift-Off Cover
As with stock pot cooking, an optional lift off cover can speed up the heating of
water and food products. A cover helps retain heat in the cooking vessel and
reduces the amount of heat and humidity released into the kitchen. Use of a
cover can reduce some product cook times and help maintain the temperature,
color and texture of products being held or simmered for extended periods.
Make sure the plastic ball handle is secure on the lift off cover before using.
ALWAYS use the plastic handle to place or remove cover from the kettle.
Wear protective oven mitts and a protective apron.
When putting the cover on the kettle, position it on top of kettle rim, with its flat
edge facing the pouring lip.
When removing cover:
a. Firmly grasp plastic handle
b. Lift rear edge (farthest from operator) 1- 2” (3-5 cm) to allow any steam
and water vapor to escape the cooking vessel. Wait 2-3 seconds.
c. Tilt cover to 45-60° angle and allow any hot condensate or product to roll
off cover back into kettle.
d. Remove cover, ensuring that any remaining hot condensate or product
does not drip on operator, floor or work surfaces.
e. Place cover on safe, flat, sanitary, out-of-the-way surface, or return to
kettle rim. Cover may also be placed in the optional holder for the cover as
shown in the photograph.
2. Basket Insert
An optional kettle basket insert can assist in cooking water-boiled products
including eggs, potatoes, vegetables, shell fish, pasta and rice.The nylon mesh
liner must be used when cooking product smaller than the mesh size of the
basket, which is approximately 1/4” (6 mm).This includes rice and small pasta
shapes. Tips for use:
a. Allow for the water displacement of the basket and product to be cooked.
This may mean only filling the kettle half full of water. Test the basket
and product displacement with the kettle OFF, and with cold water in the
kettle.
b. Load baskets on a level, stable work surface.
c. Lift loaded baskets with both hands. Get help from another person if the
basket is too heavy for safe handling.
d. Slowly lower product into kettle.
e. When removing baskets with cooked product, lift straight up, ensuring
basket bottoms clear the kettle rim and pouring lip. Wear protective oven
mitts and protective apron.
f. Allow hot water to fully drain from product before moving basket away
from the kettle. Do not rest baskets on kettle rim or pouring lip. If baskets
are too heavy for individual to lift and safely move, get help. Remove
product immediately from basket into another container, being sure to
avoid contact with hot product and hot basket or...
g. Place baskets with food on a stable, flat surface, inside a solid steamer or
bake pan,to catch any remaining hot water draining from product.

MAINTENANCE
WARNING: AVOID ANY EXPOSURE TO THE STEAM BLOWING OUT OF THE PRESSURE
RELIEF VALVE. SEVERE BURNS CAN RESULT ON EXPOSED SKIN. FAILURE
TO CHECK PRESSURE RELIEF VALVE OPERATION PERIODICALLY COULD
RESULT IN PERSONAL INJURY AND/OR DAMAGE TO EQUIPMENT.
CAUTION: KEEP GREASE AWAY FROM ELECTRICAL PARTS LOCATED NEAR THE
GEARS.
WARNING: TO AVOID INJURY, READ AND FOLLOW ALL PRECAUTIONS STATED ON THE
LABEL OF THE WATER TREATMENT COMPOUND.
WARNING: USE OF ANY REPLACEMENT PARTS OTHER THAN THOSE SUPPLIED BY
THE MANUFACTURER OR THEIR AUTHORIZED DISTRIBUTORS CAN CAUSE
INJURY TO THE OPERATOR AND DAMAGE TO THE EQUIPMENT AND WILL
VOID ALL WARRANTIES.
CAUTION: INSURE ELECTRICAL POWER IS REMOVED AND THE GAS IS TURNED OFF AT
THE SHUTOFF VALVE PRIOR TO PERFORMING ANY MAINTENANCE ON THIS
KETTLE.
WARNING: THIS KETTLE IS DESIGNED TO BE WATER RESISTANT. FAILURE TO FOLLOW
PROPER MAINTENANCE PROCEDURES MAY VOID THE WARRANTY.
The pressure gauge should show a vacuum of 20 to
30 inches when the kettle is cold
The open end of the pressure relief valve
elbow must face downward.
The pressure relief valve and fill plug are located directly
behind the pressure/vacuum gauge.
PERIODIC MAINTENANCE
NOTICE: Contact an authorized representative when repairs are required.
A Maintenance & Service Log is provided at the back of this manual. Each time
maintenance is performed on your kettle, enter the date on which the work was
done, what was done, and who did it. Keep this manual on file and available
for operators to use. Periodic inspection will minimize equipment down time and
increase the efficiency of operation. The following points should be checked:
JACKET VACUUM/REMOVING AIR FROM JACKET
Every day, while the kettle is cold, read the pressure/ vacuum gauge. A positive
reading or a negative reading between zero and 20” vacuum on the pressure/
vacuum gauge indicates excess air in the jacket. Air in the jacket slows kettle
heating and can prevent the kettle from reaching operating temperature. To
remove air:
To remove air:
1. Start the unit. (See “Operation” section).
2. Make sure the elbow on the outlet of the pressure relief valve is turned so
that escaping steam is directed down toward the floor. Be sure and follow the
instructions on the attached pressure relief valve tag.
3. When the pressure/vacuum gauge reaches a positive pressure reading of 5
PSI, release trapped air by lifting the pressure relief valve ring for about one
second. Repeat this step, then let the valve ring snap closed, so the valve will
seat properly and not leak.
PRESSURE RELIEF VALVE
At least twice a month, test the pressure relief valve. Test the valve with the kettle
operating at 15 PSI (105 kPa), by holding the test ring for at least five seconds.Then
release the ring and permit the valve to snap shut. If the ring does not activate, if
there is no discharge, or if the valve leaks, stop using the kettle immediately and
contact a authorized service representative.
GREASE / LUBRICATION
1. Hand Tilt Models
At least twice a year, grease the two trunnion bearings. The bearings are
located within the kettle support housing. Remove the access panels from
the support housing with a screwdriver to gain access to the grease fittings.
Use a lithium-based, multi-purpose grease. When the access panels are
removed, the mounting bolts for the trunnion bearings and tilt switch can also
be checked for tightness. When finished, reassemble access panels to support
housing.
2. Crank Tilt Models
The gear housing has been fitted for proper lubrication of moving parts.
Since the gears do not run in oil, periodic lubrication with grease is essential.
Frequency of lubrication depends on operating conditions, but should occur
at least once every six months. The use of a Number Two grade LGI lithium
grease is recommended. Add grease through the Zerk fittings on the gear
housing until grease flows out of the bearings around the trunnion shaft. Place
a liberal amount of grease on the gear to cover the arc that is in contact with
the worm gear.

9 OM-TDB (C,A,C2T™) & TDBC (C,A,C2T™) Domestic
JACKET FILLING
Every day, before you turn on the unit, make sure the water level is approximately
in the center of the water gauge glass. The jacket was filled at the factory with the
proper amount of treated water, and is airtight, but over time steam may be vented
and water lost.
From time to time, you may need to restore the water to its proper level. The
procedure for adding water follows.
1. If you are replacing water lost as steam, use distilled water. Do not use tap
water. If you are replacing treated water that was drained from the jacket,
prepare more treated water as directed below.
2. Allow the kettle to cool completely. Remove the pipe plug from the jacket fill
assembly. Pour in the distilled or treated water. Using a funnel will help you
in this process. Hold the pressure relief valve open while you pour, to let air
escape from the jacket. Continue adding water until the water level rises to the
center of the round sight glass.
3. Air that gets into the jacket during the filling operation must be removed,
because it will make heating less efficient. Follow the procedure in Jacket
Vacuum/Removing Air From Jacket above, to restore a negative pressure
reading.
WATER TREATMENT
1. Fill a mixing container with the amount of water required. Use only distilled
water.
Model Kettle Capacity Jacket Capacity
TDB/TDBC-20 20 qt (5 gal), 18.9 liter 7 quart, 6.6 liter
TDB/TDBC-24 24 qt (6 gal), 22.7 liter 7 quart, 6.6 liter
TDB/TDBC-40 40 qt (10 gal), 37.8 liter 9 quart, 8.5 liter
TDB/TDBC-48 48 qt (12 gal), 45.4 liter 9 quart, 8.5 liter
2. Hang a strip of pH test paper on the rim of the container, with about 1 inch of
the strip below the surface of the water.
3. Stir the water continuously, while you slowly add water treatment compound
until a color between indicating a pH of 10.5 and 11.5 is reached. (Shown on
the pH test kit chart.) Judge the pH by frequently comparing the test strip with
the color chart provided in the pH test kit. If there is a problem distinguishing
color, use a pH meter.
4. Use a measuring cup to add the compound so that you may record the exact
amount used.
5. The amount may be used again, if the same water sources and compound are
used in the future. However, it is best to check the pH each time treated water
is prepared.
SEQUENCE OF OPERATION
The following “action-reaction” outline is provided to help understand how the
kettle works.
When the operator starts up the kettle by turning the power switch to “ON” and
temperature dial from “OFF” to a desired setting, the control relay closes. This
lights up the heating indicator light and causes the contactors to close, allowing
power to flow to the heating elements.When the temperature of the steam jacket
reaches the value corresponding to the dial setting, the control relay opens. This
turns off the heating indicator light and causes the contactors to open, stopping
the power to the heaters. As soon as the control senses that the kettle is cooling
below the set point, the 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 PSI is generated in the jacket, the pressure
relief valve will open and relieve the excess pressure.
In the event that the jacket water level gets too low and the heating elements
overheat, the high limit control will open and shut off power to the elements until
the kettle cools. Setting the operating power switch to “OFF” shuts down all
control and heating circuits.
