OM/SM-EE-CE 5
Groen Model EE is a floor-mounted, stationary, steam-jacketed kettle which has a
thermostatically controlled, self-contained, electrically-heated steam supply and
appropriate controls, mounted on a sturdy base. Heat produced by electric heating
elements boils water in a reservoir below the jacket to produce steam under pressure.
The kettle is surrounded by air-insulated stainless steel sheathing. Stainless steel
panels enclose all of the controls. Three stainless steel, tubular legs support the unit.
EE kettles are available in 20 and 40 gallon capacities. Kettle bodies are welded into
one piece. Models are all equipped with a 50 mm (2 inch) sanitary tangent draw-off
(product faucet) valve and a stainless steel strainer. This standard draw-off uses a
compression disc valve. The unit is controlled with a thermostat, which turns electric
power on or off, and sets the cooking temperature. Instruments are provided to show
what is happening inside the unit:
• Water gauge glass: Shows the level of water within the steam jacket
• Pressure/vacuum gauge: Shows the steam pressure and if there is air in the
jacket
• Indicator lamps: Light when the kettle power is turned on, when the elements are
heating the jacket and when the water level in the jacket is low
Automatic controls within the unit:
• Contactor: Controlled by the thermostat, turns heating element power on or off
• Low-water cutoff: Turns off power to keep heating elements from overheating if
water loss exposes them above the water level
• Safety valve: Releases steam if jacket pressure gets too high
The jacket is filled at the factory with treated water. When air is removed from the
jacket, the kettle efficiently provides a uniform heating temperature range of 65°C
to approximately 132°C (150 to 270°F). This range allows the kettle to be used for
warming, simmering, boiling or braising.
The interior of the kettle is polished to a 180 emery grit finish and the exterior is given
a uniform Number 3 finish. The unit is ASME Code designed and shop inspected to the
Pressure Equipment Directive for working pressures up to 206 kPa (30 psi).
Optional equipment for the EE kettles includes:
• 75 mm (3 inch) draw-off valve
• Perforated or solid disc strainer
• Basket inserts (TRI-BC)
• Water fill faucets
• Kettle brush kit

OM/SM-EE-CE 9
Operation
The operator controls kettle heating with the thermostat dial. The dial turns heating
element power on or off and sets the kettle operating temperature.
A. To Start Kettle
1. EE kettles have three Indicator Lights on the Control Panel:
• POWER - Green light indicating that the power switch is set to ON and that
power is being supplied to the unit controls
• HEAT - Amber light indicating that power is being applied to the heater
elements
• LOW WATER - Red light indicating that water level is too low, and that
corrective action is required.
2. EE kettles are equipped with a Water Level Switch, mounted on a bracket above
and forward of the kettle Pressure Gauge and water gauge sight glass, inside
the control box. This switch monitors water level and turns on the LOW WATER
red light to signal the need for additional water in the kettle jacket.
3. EVERY DAY make sure the jacket water level is between the marks on the
gauge glass. If the level is too low, see “Jacket Filling and Water Treatment” on
page 15.
4. While the kettle is cold, check the pressure gauge. If the gauge does not show
20 to 30 inches of vacuum (that is, a reading of 20 to 30 below 0), see “Jacket
Vacuum” on page 14.
5. Make sure that the strainer covers the draw-off valve outlet at the bottom of the
kettle. This keeps food solids from collecting in the draw-off area.
B. To Transfer Product or Empty Kettle
1. The kettle is emptied by means of its drawoff valve, by ladling product out, or
with the optional tri-basket insert.
2. Use of Optional Basket Insert: The optional kettle basket insert set will assist in
cooking water boiled products such as eggs, potatoes, vegetables, shell fish,
pasta and rice. The nylon mesh liner must be used for products smaller than
the basket mesh size, (approximately 6 mm (¼ in). This includes rice and small
pasta shapes.
Tips For Use:
1. Allow for displacement of the three baskets and product. This may mean only
filling the kettle half way. Test baskets and product displacement with the kettle
thermostat set to “0” and power switch set to OFF, and with cold water in the
kettle.
2. Load baskets on a level, stable work surface.
3. Lift loaded baskets with both hands. Get help from another person if the basket
is too heavy for safe handling.
4. Slowly lower product into kettle and securely hook the basket to the “Y” frame.
CAUTION
DO NOT OVERFILL THE KETTLE WHEN
COOKING, HOLDING OR CLEANING.
KEEP LIQUIDS AT LEAST 5-8 CM (2-3
INCHES) BELOW THE KETTLE BODY RIM TO
ALLOW CLEARANCE FOR STIRRING,
BOILING PRODUCT AND SAFE TRANSFER.
WARNING
OPEN THE KETTLE LID CAREFULLY TO
AVOID STEAM WHICH MAY ESCAPE.
DIRECT CONTACT COULD RESULT IN
SEVERE BURNS.
CAUTION
KEEP FLOORS IN FRONT OF THE KETTLE
WORK AREA CLEAN AND DRY.
IF SPILLS OCCUR, CLEAN AT ONCE TO
AVOID SLIPS OR FALLS.
Be sure that the pressure/vacuum gauge
shows at least 20 inches of vacuum.
Each day, confirm the jacket water
level by checking the water gauge.

5. When removing baskets with cooked product, lift straight up, ensuring basket
bottoms clear the kettle rim. Wear protective oven mitts and protective apron.
6. 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 one 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:
7. 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.
C. To Turn Off the Kettle
1. Turn the thermostat dial to “0” and set the power switch to OFF.
2. Before the unit is serviced, or if it will be off for a week or more:
3. Set the thermostat to “0”.
4. Turn the power switch to OFF (the green lamp should go out) and switch off
electric power to the unit at the circuit breaker or fuse.
CAUTION
DO NOT OVERFILL THE KETTLE WHEN
COOKING, HOLDING OR CLEANING.
KEEP LIQUIDS AT LEAST 5-8 CM (2-3
INCHES) BELOW THE KETTLE BODY RIM TO
ALLOW CLEARANCE FOR STIRRING,
BOILING PRODUCT AND SAFE TRANSFER.

OM/SM-EE-CE 11
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 power switch to ON (which
lights the green POWER lamp) and turning the operating thermostat dial from “0” to a
desired setting, the thermostat switch closes. This lights up the HEAT amber 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 HEAT indicator light and
causes the contactors to open, cutting 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 HEAT 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.
If steam pressure greater than 206 kPa (30 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 operating thermostat dial to “0” shuts down the heating circuits. Setting
the power switch to OFF removes power from the control circuits.

12 OM/SM-EE-CE
Cleaning
WARNING
KEEP WATER AND SOLUTIONS OUT OF
CONTROLS AND ELECTRICAL EQUIPMENT.
NEVER SPRAY THE SUPPORT HOUSING OR
ELECTRICAL CONNECTIONS.
1. Suggested Cleaning Supplies:
a. Cleaner, such as Klenzade HC-10 or HC-32 from ECOLAB, Inc.
b. Kettle brushes in good condition (and a bottle brush, for the draw-off).
c. Sanitizer such as Klenzade XY-12.
d. Film remover such as Klenzade LC-30.
2. Precautions
Before cleaning, shut off the kettle by turning the thermostat dial to “0”, turn the
power switch to OFF, and shut off all electric power to the unit at a remote switch,
such as the circuit breaker.
3. Procedure
a. Clean food-contact surfaces as soon as possible after use. If the unit is in con-
tinuous 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. Close the draw-off.
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, housing, and electrical conduits.
d. Rinse the kettle thoroughly with hot water, then drain completely.
e. Disassemble the tangent draw-off valve. Clean the draw-off port and each valve
part with a brush.
f. Rinse the kettle and draw-off valve parts thoroughly with hot water, then drain
completely.
g. As part of the daily cleaning program, clean soiled external and internal sur-
faces. Remember to check the sides of the unit and control housing.
h. 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 even-
tual corrosion and pitting.
i. The outside of the unit may be polished with a stainless steel cleaner such as
“Zepper” from Zep Manufacturing Co. or Groen DeGreaser (Part No. 140830).
j. When equipment needs to be sanitized, use a solution equivalent to one that
supplies 200 parts per million available chlorine. Obtain advice on sanitiz-
ing 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.
k. It is recommended that each piece of equipment be sanitized just before use.
CAUTION
DO NOT MIX THE PARTS OF DIFFERENT
DRAW-OFF ASSEMBLIES DURING
WASHING. THE PARTS ARE NOT ALWAYS
INTERCHANGEABLE.
Use a brush, sponge, cloth, plastic or
rubber scraper, or plastic wool to clean.
Don’t use metal implements
or steel wool when cleaning.
CAUTION
MOST CLEANERS ARE HARMFUL TO THE
SKIN, EYES, MUCOUS MEMBRANES AND
CLOTHING. PRECAUTIONS SHOULD BE
TAKEN TO WEAR RUBBER GLOVES,
GOGGLES OR FACE SHIELD AND
PROTECTIVE CLOTHING. CAREFULLY
READ THE WARNINGS AND FOLLOW
LABEL DIRECTIONS.

OM/SM-EE-CE 13
Cleaning
l. 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), in accordance with the manu-
facturer’s directions. Rinse and drain the unit before further use.
m. If cleaning problems persist, contact your cleaning product representative for
assistance.
3. Ball Valve
Some kettles are equipped with an optional ball valve. This valve can be easily
disassembled for cleaning. These parts may be cleaned in a standard sanitizer or in
a dish washing machine.
CAUTION
NEVER LEAVE A CHLORINE SANITIZER IN
CONTACT WITH STAINLESS STEEL
SURFACES FOR LONGER THAN 30
MINUTES. LONGER CONTACT CAN
CAUSE CORROSION.

14 OM/SM-EE-CE
Maintenance
NOTICE: Contact Groen or an authorized representative 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. The following points should be checked:
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”
below.
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 15.
c. Test the safety valve at least twice each month. Test the valve with the kettle
operating at 105 kPa (15 psi), by pulling up the test valve chain for at least 5
seconds. Then release lever and let the valve snap shut. If the valve does not
activate, or there is no evidence of discharge, or the valve leaks, stop using the
kettle and contact a qualified Groen service representative.
2. Jacket Vacuum
Test the safety valve at least twice monthly. When the kettle is cold, a positive
pressure/ vacuum gauge reading or a reading near zero indicates that there is air
in the jacket. Air in the jacket slows kettle heating. To remove air:
a. Start the unit. (Be sure there is water or product in the kettle when heating).
b. Make sure that the elbow of the safety valve outlet is turned so that escaping
steam is directed toward the floor.
c. When the pressure/vacuum gauge reaches a positive pressure reading of 34 kPa
(5 psi), release the trapped air and steam by pulling up or out on the safety valve
lever or ring for about 1 second. Repeat this step, then let the pull ring or valve
lever snap back into the closed position.
WARNING
WHEN TESTING, AVOID ANY EXPOSURE
TO THE STEAM BLOWING OUT OF THE
SAFETY VALVE. DIRECT CONTACT
COULD RESULT IN SEVERE BURNS.
Be sure that the pressure/vacuum gauge
shows at least 20 inches of vacuum.

OM/SM-EE-CE 15
Maintenance
WARNING
STAY AWAY FROM THE STEAM THAT IS
BLOWING OUT OF THE SAFETY VALVE.
THE STEAM CAN CAUSE A SEVERE BURN.
WARNING
TO AVOID INJURY, READ AND FOLLOW ALL
PRECAUTIONS STATED ON THE LABEL OF
THE WATER TREATMENT COMPOUND.
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 because it was lost as steam during venting or by
draining.
a. 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 step 4, “Water Treatment Procedure.” Do not use tap water.
b. Allow the kettle to cool Remove the pipe plug from the jacket fill assembly.
c. Open the gate valve and pour in the distilled or treated water.
d. Hold the safety valve open to allow air to escape from the jacket while you pour
in the water. Continue to pour until the water level rises to a point between the
marks on the gauge glass.
e. Any air introduced into the jacket during filling must be removed to obtain
efficient heating. See “Jacket Vacuum” on page14.
4. Water Treatment Procedure
a. Obtain water treatment compound and a pH test kit from your Groen distributor.
b. Fill a mixing container with the measured amount of water required. (See table
at left). Use distilled water only.
c. Hang a strip of pH test paper on the rim of the container, with about 1 inch
(25mm) of the strip below the surface of the water.
d. Measure the water treatment compound (One way to do this is to add the
compound from a measuring cup.)
e. 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 chart provided in the pH test
kit. If you are color blind read the test strip color level.
f. 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.
