1.0 Equipment Description
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, 40, 60 and 80 gallon
capacities. Kettle bodies are welded into one piece.
Models are all equipped with a two inch (50 mm)
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 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 treated water.
When air is removed from the jacket, the kettle
efficiently provides a uniform heating temperature
range of 150 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 PSIG (206 kPa).
Optional equipment for the EE and AE kettles
includes:
• Three inch (75 mm) draw-off valve
• Perforated or solid disc strainer
• Basket inserts (TRI-BC)
• Water fill faucets
• Automatic water filler
• Kettle brush kit

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
5.1 EE kettles have three Indicator Lights
on the Control Panel:
• Power Light - Indicates that power
is being supplied to the unit
• Heat Light - Indicates that power
is being applied to the heater
elements
• Low Water Light - Indicates that
water level is too low, and that
corrective action is required.
5.2 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 light to signal the need for additional
water in the kettle jacket.
5.3 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 12.
5.4 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 11.
5.5 Make sure that the strainer covers the draw-off
Be sure that the pressure/vacuum gauge
shows at least 20 inches of vacuum.
valve outlet at the bottom of the kettle. This
keeps food solids from collecting in the draw-off
area.
5.6 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.
5.7 To transfer Product or Empty Kettle:
5.7.1 The kettle is emptied by means of its draw-
off valve, by ladling product out, or with the
optional tri-basket insert.
5.7.2 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.
5.8 To Turn Off the Kettle
5.8.1 Turn the thermostat dial to “OFF.”
5.8.2 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

WARNING
OPEN THE KETTLE LID CAREFULLY TO
AVOID STEAM WHICH MAY ESCAPE.
DIRECT CONTACT COULD RESULT IN
SEVERE BURNS.
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 PSIG 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 “OFF” shuts
down all control and heating circuits.

g. As part of the daily cleaning program, clean
soiled external and internal surfaces.
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 eventual
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 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.
k. It is recommended that each piece of
equipment be sanitized just before use.
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) or
Lime-A-Way®from Ecolab, in accordance
with the manufacturer’s directions. Rinse
and drain the unit before further use.
m. If cleaning problems persist, contact your
cleaning product representative for
assistance.

7.1 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.
Be sure that the pressure/vacuum gauge shows
at least 20 inches of vacuum.
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 12.
c. 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
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.
7.2 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).
7.0 Maintenance
NOTICE: Contact Groen or an authorized Groen representative when repairs are required.

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.
7.3 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 7.4,
“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” above.
7.4 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). Use
distilled water only.
Kettle Model Jacket Capacity
EE-20 31/4Gallons
EE-30 41/2Gallons
EE-60 73/4Gallons
EE-80 10 Gallons
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.
