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.
To put the cover on the kettle, position it
with its flat edge facing the pouring lip.
CAUTION
DO NOT TILT KETTLE BODY WITH COVER
OR BASKET INSERT IN PLACE. COVER
MAY SLIDE OFF, CAUSING INJURY TO
OPERATOR.
Lift the rear edge of the cover first.
10
Page 11
OM-TDB/C
2. Optional Basket Insert
A kettle basket insert can assist in cooking
water-boiled products ( eggs, potatoes,
vegetables, shellfish, pasta and rice). The
nylon mesh liner must be used when
cooking products smaller than the basket
mesh size, (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. 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.

to flow to heating elements. 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

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 thermostat dial to “OFF” shuts down
all control and heating circuits.

Maintenance
NOTICE: Contact Groen or an authorized Groen Service Agent when repairs are required.
1. Periodic Maintenance
A Maintenance & Service Log is provided at
the back of this manual with the warranty
information. Each time maintenance is
performed on your Groen 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. Check the following points:
a. Check the pressure/vacuum gauge
every day. The gauge should show a
vacuum of 20 to 30 inches, when the
kettle is cold. If it does not, see “Jacket
Vacuum” Paragraph 2, below.
seconds. Then release the lever and let
the valve snap shut. If the lever does
not activate, or there is no evidence of
discharge, or the valve leaks,
immediately discontinue use of the
kettle and contact a qualified Groen
service representative.
WARNING
WHEN TESTING, AVOID ANY EXPOSURE
TO THE STEAM BLOWING OUT OF THE
SAFETY VALVE. DIRECT CONTACT COULD
RESULT IN SEVERE BURNS.
DISCONNECT ELECTRICAL POWER FROM
THE KETTLE BEFORE ATTEMPTING TO
GREASE THE TRUNNION BEARINGS.
2. Jacket Vacuum
When the kettle is cold, a positive pressure
reading or a reading around zero on the
pressure/vacuum gauge indicates the
presence of air in the jacket. Air in the
jacket slows down the heating of the kettle.
The pressure gauge should show a vacuum
of 20 to 30 inches when the kettle is cold.
b. Also check the jacket water level on a
daily basis. It should be above mid
point of round sight glass. If the level is
low, see “Jacket Filling and Water
Treatment,” Paragraph 3, below.
c. Ensure that electrical wiring is securely
connected and in good condition.
d. Keep the inside of the support housing
clean.
e. Test the safety valve at least twice each
month. Test the valve with the kettle
operating at 15 psi (105 kPa), by
holding the test lever for at least 5
To remove air:
a. Start the unit. (Be sure there is water or
product in the kettle when heating).
b. When the pressure/vacuum gauge
reaches a positive pressure reading of
five PSI, release the trapped air and
steam by pulling up on the safety valve
ring for about a second. Let the pull ring
snap back into the closed position.
Repeat this step immediately after the
gauge again reads five PSI.
3. Jacket Filling and Water Treatment
The jacket was charged at the factory with
the proper amount of treated water. You
may need to restore the water to its proper
level, either because water was lost as
steam during venting or because treated
water was lost by draining.
12
Page 13
IMPORTANT
PRESSURE GAUGE MUST READ LESS
THAN 0 PSIG BEFORE YOU FILL JACKET
WITH WATER.
To fill jacket with water:
a. If you are replacing water lost as steam,
use distilled water. If you are replacing
treated water drained from the jacket,
prepare more treated water as directed
in step 4, “Water Treatment Procedure”.
b. Remove fill plug with open-end wrench
or crescent wrench.
c. Open shutoff valve (turn handle 90E on
gate valve).
OM-TDB/C
d. Use a funnel and add water to jacket.
e. Check water level in jacket, by viewing
water level sight glass.
f. Continue to add water until the water
level sight glass is 3/4 full.
g. Close gate valve, and install fill plug.
h. Follow procedure under “Jacket

4. Water Treatment Procedure
WARNING
TO AVOID INJURY, READ AND FOLLOW
ALL PRECAUTIONS STATED ON THE
LABEL OF THE WATER TREATMENT
COMPOUND.
(1) Fill the mixing container with the Model Kettle Jacket
measured amount of water required.
(See the table at right). Distilled water is
recommended.
(5) Record the exact amounts of water and
treatment compound used. These
amounts may be used again, if the
same sources of water and compound
are employed to refill the jacket in the
future. However, it is advisable to check
the pH every time treated water is
prepared.
Capacity Capacity
TDB/C-20 20 quarts 4 quarts
TDB/C-40 40 quarts 5 quarts
(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) Measure the water treatment compound
you will be using. (One way to do this is
to add the compound from a measuring
cup.)
(4) Stir the water continuously, while you
slowly add water treatment compound,
until the water reaches a pH between
10.5 and 11.5. Judge the pH by
frequently comparing the color of the
test strip with the color chart provided in
the pH test kit. Color blind people
mixing the treated water solution must
use an electro-analytical instrument to
measure the pH level or have a person
that is not color blind read the test strip
color level.

leave particles in the surface and
cause eventual corrosion and pitting.
g. The outside of the unit may be
polished with a stainless steel cleaner
such as “Zepper” from Zep
Manufacturing Co.
h.h. 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. Following the
supplier’s instructions, apply the agent
after the unit has been cleaned and
drained. Rinse off the sanitizer
thoroughly.
j. If there is difficulty removing mineral
deposits or a film left by hard water or
food residues, clean the kettle
thoroughly and then use a deliming
agent, like Groen Delimer/Descaler
(Part Number 114800) or Lime-Away
from Ecolab, in accordance with the
manufacturer’s directions. Rinse and
drain the unit before further use.
k. If cleaning problems persist, contact
your cleaning product representative
for assistance. The supplier has a
trained technical staff with laboratory
facilities to serve you.
