STEAM JACKETED KETTLE
MODELS EE DOMESTIC
EQUIPMENT DESCRIPTION
Groen Model EE are floor-mounted, tilting, steam-jacketed kettles which have
thermostatically controlled, self-contained, electrically-heated steam supplies
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, 40, 60, 80 and 100 gallon capacities. Kettle bodies
are welded into one piece. Models are all equipped with a sanitary tangent
draw-off (product faucet) valve and a stainless steel strainer. This standard
draw-off is two inches in diameter, and 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 lamp: Lights when the kettle is being heated
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 water that contains rust inhibitors. When
air is removed from the jacket, the kettle efficiently provides a uniform heating
temperature range of 150oF to approximately 270oF (65 to 132oC). 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 4 finish. The unit is ASME shop inspected and registered
with the National Board for working pressures up to 30 PSI.
Optional equipment for the EE and AE kettles includes:
• Three inch draw-off valve
• 1/4” perforated or solid disc strainer
• Basket inserts (TRI-BC)

4 OM-EE
TO START KETTLE
1. 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”.
2. 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”. Be sure that the pressure/vacuum gauge shows at least 20 inches
of vacuum.
3. 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.
4. Turn the thermostat dial to the desired setting. The indicator light will confirm
that the kettle is heating. Cycling of the light on and off shows that the kettle is
being held at the set temperature. Once in each cycle contactors in the support
housing will make a clicking sound. This is normal.
TO TRANSFER PRODUCT OR EMPTY KETTLE
1. The kettle is emptied by means of its draw-off 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 1/4” (6 mm). This includes rice and small
pasta shapes.
Tips For Use:
a) 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 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 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. 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 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. . .
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.
TO TURN OFF THE KETTLE
1. Turn the thermostat dial to “OFF.”
2. Before the unit is serviced, or if it will be off for a week or more:
a. Set the thermostat to “OFF.”
b. Turn off electric power to the unit at the circuit breaker or fuse.
CLEANING
WARNING: KEEP WATER AND SOLUTIONS OUT OF CONTROLS AND ELECTRICAL
EQUIPMENT. DO NOT USE A HIGH PRESSURE HOSE TO CLEAN THE CONTROL
CONSOLE, ELECTRICAL CONNECTIONS, ETC.
WARNING: AVOID ANY DIRECT CONTACT WITH HOT SURFACES. DIRECT SKIN CONTACT
COULD RESULT IN BURNS.
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.
NOTICE: NEVER LEAVE A CHLORINE SANITIZER IN CONTACT WITH STAINLESS STEEL
SURFACES LONGER THAN 30 MINUTES. LONGER CONTACT CAN CAUSE
STAINING AND CORROSION.
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.
SUGGESTED CLEANING SUPPLIES
1. Cleaner, such as Klenzade HC-10 or HC-32 from ECOLAB, Inc.
2. Kettle brushes in good condition (and a bottle brush, for the draw-off).
3. Sanitizer such as Klenzade XY-12.
4. Film remover such as Klenzade LC-30.
PRECAUTIONS
Before cleaning, shut off the kettle by turning the thermostat dial to “OFF” and
unplug the unit or shut off its electric power at a remote switch, such as the circuit
breaker.
PROCEDURE
1. Clean food contact surfaces as soon as possible after use, preferably while the
kettle is still warm. If the unit is in continuous use, clean and sanitize inside
and outside at least once every 12 hours.
2. Scrape and flush out food residues. Be careful not to scratch the kettle with
metal implements. Close the draw-off.
3. Prepare a 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 and electrical conduits.
4. Disassemble the tangent draw-off valve. Clean the draw-off port and each
valve part with a brush.
5. Rinse the kettle and draw-off valve parts thoroughly with hot water to remove
every trace of detergent. Drain completely and allow them to AIR dry or wipe
them dry. (The agitator may be cleaned in a dishwasher).
6. As part of the daily cleaning program, clean soiled external and internal
surfaces. Remember to check the sides and back of the unit.
7. 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.

5 OM-EE
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. Following the supplier’s
instructions, apply the agent after the unit has been cleaned and drained.
Rinse off the sanitizer thoroughly.
10. It is recommended that the equipment be sanitized just before use.
11. If there is difficulty removing mineral deposits or a film left by hard water
or food residues, clean the kettle thoroughly and 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.
12. If cleaning problems persist, contact your cleaning product representative for
assistance. The supplier has a trained technical staff with laboratory facilities
to serve you.
MAINTENANCE
WARNING: WHEN TESTING, AVOID ANY EXPOSURE TO THE STEAM BLOWING OUT OF
THE SAFETY VALVE. DIRECT CONTACT COULD RESULT IN SEVERE BURNS.
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.
NOTICE: Contact an authorized representative when repairs are required.
PERIODIC MAINTENANCE
A Maintenance & Service Log is provided at the back of this manual. Each time
there is maintenance performed on your Groen kettle, enter the date 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 often:
1. 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”.The pressure gauge should show a vacuum of 20 to 30 inches when
the kettle is cold.
2. 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”.
3. Test the safety valve at least twice each month. Test the valve with the kettle
operating at 15 psi (105 kPa), by pulling up the test valve chain for at least 5
seconds. Then release the 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.
JACKET VACUUM
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. Test the
safety valve at least twice monthly.
To remove air:
1. Start the unit. (Be sure there is water or
product in the kettle when heating).
2. Make sure that the elbow of the safety
valve outlet is turned so that escaping
steam is directed toward the floor.
3. When the pressure/vacuum gauge reaches a positive pressure reading of 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.
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.
1. 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.” Do not use tap water.
2. Allow the kettle to cool. Remove the pipe plug from the jacket fill assembly.
3. Open the gate valve and pour in the distilled or treated water.
4. 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.
5. Close the gate valve and replace the pipe plug.
6. Any air introduced into the jacket during filling must be removed to obtain
efficient heating. See “Jacket Vacuum”.
WATER TREATMENT PROCEDURE
1. Obtain water treatment compound and a pH test kit from your Groen distributor.
2. Fill a mixing container with the measured amount of water required. (See
table). Distilled water is recommended.
KETTLE MODEL: JACKET CAPACITY:
EE-20 3-1/4 Gallons
EE-40 6-1/2 Gallons
EE-60 7-3/4 Gallons
EE-80 10 Gallons
EE-100 10 Gallons
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 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.

6 OM-EE
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, 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 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.
If steam pressure greater than 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, the high- limit control will open and shut
off power to the elements until the kettle cools. This will prevent the heating
elements from overheating.
Setting the operating thermostat dial to “OFF” shuts down all control and heating
circuits.
