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.

CLEANING

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

PRECAUTIONS

Before cleaning, shut off the kettle by turning the main power switch to “OFF,” and
shut off all electric power to the unit at a remote switch, such as the circuit breaker.

PROCEDURE

1. Clean food-contact surfaces as soon as possible after use. If the unit is in
continuous use, thoroughly clean and sanitize the interior and exterior at least
once every 12 hours.

2. Scrape and flush out food residues. Be careful not to scratch the kettle with
metal implements.

3. Prepare a hot solution of the detergent/cleaning compound as instructed
by the supplier. Clean the unit thoroughly. A cloth moistened with cleaning
solution can be used to clean controls, housings, and electrical conduits.

4. Rinse the kettle and draw-off valve parts thoroughly with hot water, then drain
completely.

5. As part of the daily cleaning program, clean soiled external and internal
surfaces. Remember to check the sides of the unit and control housing,
underside of cover, etc.

6. To remove burnt on foods, use a brush, sponge, cloth, plastic or rubber scraper,
or plastic wool with the cleaning solution. To reduce effort required in washing,
let the detergent solution sit in the kettle and soak into the residue. Do NOT use
abrasive materials or metal tools that might scratch the surface. Scratches
make the surface harder to clean and provide places for bacteria to grow.
Do NOT use steel wool, which may leave particles in the surface and cause
eventual corrosion and pitting.

7. The outside of the unit may be cleaned with a warm water (100°F or less)
spray. Do not use a high pressure spray.

8. The outside of the unit may be polished with a stainless steel cleaner such as
“Zepper” from Zep Manufacturing Co.

9. When equipment needs to be sanitized, use a solution equivalent to one that
supplies 200 parts per million available chlorine. Obtain advice on sanitizing
agents from your supplier of sanitizing products.

10. It is recommended that each piece of equipment be sanitized just before use.

11. Clean the kettle thoroughly. If there is difficulty removing mineral deposits or a
film left by hard water or food residues, then use a de-liming agent, following
manufacturer directions.

12. Rinse and drain the unit thoroughly before further use.

13. If cleaning problems persist, contact your cleaning product representative for
assistance. The supplier has a trained technical staff with laboratory facilities
to serve you.

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.

8 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.

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.

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.
