Equipment Description
The Groen DEES is a floor-mounted, tilting,
steam jacketed kettle with a thermostatically
controlled, self-contained, electrically-heated
steam supply and appropriate controls, mounted
on a sturdy base.
The body of the DEES 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 working pressures up to 50 PSI. Kettle
finish is 180 emery grit on the inside and bright
semi-deluxe on the outside.
The kettle can be tilted with a hand crank to pour
out its contents. Stainless steel panels enclose
the controls and the base. Four stainless steel,
tubular legs support the unit. Bullet feet on each
of the legs can be adjusted to level the kettle.
DEES/T units include a two inch tangent draw off
valve.
A built-in steam generator, sized for the kettle
capacity and heated by electricity, 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
298°F. In addition to the adjustable thermostat
for operating control, the unit has a tilt cut-off
switch, low water cut-off, safety valve, and highlimit 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, 400 or 480 volt power. All kettles are

Use Of Common Accessories
1. Lift-Off or Counterbalanced Cover
As with stock pot cooking, an optional cover
can speed up the heating of water and food
products. A cover helps retain heat and
reduces the heat and humidity released into
the kitchen. Using a cover can reduce some
product cook times and help maintain the
temperature, color and texture of products
being held or simmered for longer periods.
Be sure the handle is secure on the lift-off
cover before using. ALWAYS use the handle
to place or remove cover from the kettle.
Wear protective oven mitts and a protective
apron.
When putting a lift-off cover on the kettle,
position it on top of kettle rim, with its flat
edge facing the pouring lip.
WARNING
AVOID ALL DIRECT CONTACT WITH HOT
SURFACES. DIRECT SKIN CONTACT
COULD RESULT IN SEVERE BURNS.
AVOID ALL DIRECT CONTACT WITH HOT
FOOD OR WATER IN THE KETTLE.
DIRECT CONTACT COULD RESULT IN
SEVERE BURNS.
When removing the lift-off cover:
a) Firmly grasp the handle
b) Lift rear
edge (farthest from operator) 12” (3-5 cm) to allow steam and water
vapor to escape the cooking vessel.
Wait 2-3 seconds.
c) Tilt cover to 45-60° angle to 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.

OM-DEES
e) Place cover on safe, flat, sanitary, out-of-
the-way surface, or return to kettle.
CAUTION
DO NOT TILT KETTLE WITH LIFT-OFF
COVER IN PLACE. COVER MAY SLIDE
OFF, CAUSING INJURY TO OPERATOR.
2. Basket Insert
An optional kettle basket insert set can assist
in cooking water-boiled products including
eggs, potatoes, vegetables, shell fish, pasta
and rice. The nylon mesh liner must be used
for 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 displacement of the 3 baskets
and product. This may mean only filling
the kettle half way. Test baskets and
product displacement with the kettle OFF,
and with cold water in the kettle.
CAUTION
DO NOT OVERFILL THE KETTLE WHEN
COOKING, HOLDING OR CLEANING.
KEEP LIQUIDS AT LEAST 2-3” (5-8 cm)
BELOW THE KETTLE RIM TO ALLOW
CLEARANCE FOR STIRRING, BOILING
AND SAFE PRODUCT TRANSFER.
WARNING
AVOID ALL DIRECT CONTACT WITH HOT
FOOD OR WATER IN THE KETTLE.
DIRECT CONTACT COULD RESULT IN
SEVERE BURNS.
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 and
securely hook the basket to the “Y” frame.
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.

Sequence of Operation
The following “action-reaction” outline is provided
to help the user understand how the equipment
works.
When the operator starts up the kettle by turning
the operating thermostat dial from “OFF” to a
desired setting, the thermostat switch closes.
This lights up the heating indicator light and
causes the contactors to close, allowing power 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
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 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 operation thermostat dial to “OFF”
shuts down all control and heating circuits.
The kettle has the following safety features in
addition to the 90-second ignition timer:
1. Low water cutoff relay that will shut off gas
supplies to all burners until the jacket water
level is corrected.
2. High limit pressure switch, set to open at
about 46 PSI and to shut down the burners
until jacket pressure is decreased.
3. Pressure relief valve, which will release
steam if jacket pressure exceeds 50 PSI.
4. Tilt switch, which shuts off all burners when
the kettle is tilted.
5. Gas pressure regulator built into the gas
control valve.
OM-DEES
12
Page 13
OM-DEES
Test the safety valve at least twice
monthly.
Test the pressure relief valve at least
twice monthly.
The pressure gauge should show a vacuum
of 20 to 30 inches when the kettle is cold.
Maintenance
NOTICE: Contact Groen or an authorized Groen representative when repairs are required.
1. Periodic Maintenance
A 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. The following points should be
checked:
[BY OPERATOR]
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” on page 13.
b. Also check the jacket water level every
day. It should be between the marks on
the gauge glass. If the level is low, see
“Jacket Filling and Water Treatment” on
page 13.
c. Carefully test the pressure relief valve at
least twice each month. With the kettle
operating at 15 psi (105 kPa),pull the test
lever and let it snap back to its closed
position. If there is little discharge (mostly
air), and the pressure gauge drops back
to zero PSI, allow the pressure to build
back to five PSI and repeat the
procedure. (Tip: Using a screwdriver or
other implement to pull the ring will help
you avoid contact with the steam.
WARNING
WHEN TESTING, AVOID ANY EXPOSURE
TO THE STEAM BLOWING OUT OF THE
SAFETY VALVE. DIRECT CONTACT
COULD RESULT IN SEVERE BURNS.
[BY SERVICE TECHNICIAN]
d. Electrical wiring should be kept securely
connected and in good condition.
e. The inside of the support housing should
be kept clean.
OM-DEES

OM-DEES
Liberally grease the wheel where it contacts the
worm gear.
f. The gear housing has fittings for lubrication
of moving parts. The gears do not run in oil,
so periodic lubrication with grease is
necessary.
g. Frequency of lubrication depends on
operating conditions, but it should be done at
least once every six months.
h. Use a #2 grade LGI lithium grease to add
grease through Zerk fittings on gear housing
until it flows out of the bearings around the
trunnion shaft.
i. Place liberal amounts of grease on the gear
to cover the arc that is in contact with the
worm gear.
j. Keep electrical wiring and connections in
good condition.
k. Keep the inside of the control console clean
and dry.

2. Jacket Vacuum/Removing Air from
Jacket
When the kettle is cold, a positive pressure
reading on the pressure/vacuum gauge or a
reading near zero indicates that there is air
in the jacket. Air in the jacket acts as an
insulator, and slows kettle heating.
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 the safety valve ring
for about five seconds. Repeat this step
three or four times. Then let the pull ring
snap back into the closed position.
c. If there is little discharge (mostly air),
and the pressure gauge drops back to
zero PSI, allow the pressure to build
back to five PSI and repeat the
procedure.
d. Once steam has been vented from the
jacket as described in b, above, remove
the hot water from the kettle and replace
it with cold. This will condense steam in
the kettle jacket, and the pressure gauge
should show a reading of 20 to 30
inches mercury (Hg) below zero. If it
does not, or if the vacuum is leaking
down, contact a Groen authorized
service agency to correct the problem.
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 this water, either because it
was lost as venting steam or by draining. If
you are replacing water lost as steam, use
distilled water. If you are replacing treated
water that ran out of the jacket, prepare more
treated water as directed in “Water Treatment
Procedure,” below.
Test the safety valve at least twice monthly.
a. Allow the kettle to cool completely. The
procedure will be easier with the kettle under
vacuum ( pressure gauge reading below
zero).
b. 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.
c. Position a funnel in the opening and fill it with
properly treated water.
d. 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.
4. Water Treatment Procedure
(1) Obtain water treatment compound and a
pH test kit from your authorized Groen
parts distributor.
WARNING
TO AVOID INJURY, READ AND FOLLOW
ALL PRECAUTIONS STATED ON THE
LABEL OF THE WATER TREATMENT
COMPOUND.
(2) Fill a mixing container with the measured
amount of water required. (See table).
Distilled water is recommended.

(3) 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.
(4) Measure the water treatment compound
(One way to do this is to add the
compound from a measuring cup.)
(5) 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 test strip color
with the color chart provided in the pH
test kit. If you are color blind use an
electroanalytical instrument to measure
the pH level or have a person who is not
color blind read the test strip color level.
(6) Record the exact amounts of water and
treatment compound used. These
amounts 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.

Use only a sponge, cloth or plastic brush to
clean the kettle.
Scrapers or steel wool can harm the kettle
surface.
Cleaning
1. Suggested Tools
a. Cleaner, such as Klenzade HC-10 or
HC-32 from ECOLAB, Inc.
b. Kettle brushes in good condition.
c. Sanitizer such as Klenzade XY-12.
d. Film remover such as Klenzade LC-30.
e. Groen Spray Degreaser (p/n 114801)
f. Groen DeLimer/Descaler (p/n 114800)
2. Precautions
Before cleaning, shut off the kettle by turning
the thermostat dial to “OFF,” and shut off all
electric power to the unit at a remote switch,
such as the circuit breaker.
WARNING
KEEP WATER AND SOLUTIONS AWAY
FROM CONTROLS AND ELECTRICAL
EQUIPMENT. NEVER SPRAY THE
SUPPORT HOUSING OR ELECTRICAL
CONNECTIONS.
CAUTION
MOST CLEANERS ARE HARMFUL TO THE
SKIN, EYES, MUCOUS MEMBRANES, AND
CLOTHING. PRECAUTIONS SHOULD BE
TAKEN. W EAR RUBBE R G L OVES,
GOGGLES OR FACE SHIELD, AND
PROTECTIVE CLOTHING. READ THE
W AR N I N G S A N D F O L L O W T H E
DIRECTIONS ON THE LABEL OF THE
CLEANER CAREFULLY.
3. Procedure
a. 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.
b. Scrape and flush out food residues. Be
careful not to scratch the kettle with metal
implements.
CAUTION
NEVER LEAVE A SANITIZER IN CONTACT
WITH STAINLESS STEEL SURFACES
LONGER THAN 30 MINUTES. LONGER
CONTACT CAN CAUSE CORROSION.
c. 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.
d. Rinse the kettle thoroughly with hot water,
then drain completely.
e. As part of the daily cleaning program, clean
soiled external and internal surfaces.
Remember to check the sides of the unit and
control housing.
f. To remove stuck materials, 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.

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.
NOTICE
NEVER LEAVE A CHLORINE SANITIZER IN
CONTACT WITH STAINLESS STEEL
SURFACES LONGER THAN 30 MINUTES.
LONGER CONTACT CAN CAUSE STAINING
AND CORROSION.
i. It is recommended that each piece of
equipment be sanitized just before use.
i. 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.
j. If cleaning problems persist, contact your
cleaning product representative for
assistance. The supplier has a trained
technical staff with laboratory facilities to
serve you.
