Equipment Description

OM-EE

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
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

• Pressure/vacuum gauge: shows the steam

• Indicator lamp: Lights when the kettle is

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 wate
contains rust inhibitors. When air is removed
from the jacket, the kettle efficiently provides a
uniform heating temperature range of 150
approximately 270
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.

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. 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

11.

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” on page 10.

Be sure that the pressure/vacuum
gauge shows at least 20 inches of
vacuum.

Operation

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.

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.

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.

B. 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.

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.

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

OM-EE

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.

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.

B. 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.”

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. . .

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.

b. Turn off electric power to the unit at the

circuit breaker or fuse.

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.

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

If the jacket water level gets too low, the high­limit 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.

Maintenance

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

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.

2. Jacket Vacuum

When the kettle is cold, a positive pressure/

The pressure gauge should show a vacuum
of 20 to 30 inches when the kettle is cold.

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 11.

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 the lever
and let the valve snap
shut. If the valve does

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 5
PSI, release the trapped air and steam

OM-EE

this step, then let the pull ring or valve
lever snap back into the closed position.

f. Any air introduced into the jacket during

filling must be removed to obtain
efficient heating. See “Jacket Vacuum”
above.

4. Water Treatment Procedure

(1) Obtain water treatment compound and a

pH test kit from your Groen distributor.

WARNING
STAY AWAY FROM THE STEAM THAT IS
BLOWING OUT OF THE SAFETY VALVE.
THE STEAM CAN CAUSE A SEVERE
BURN.

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. Close the gate valve and replace the

pipe plug.

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.

EE-30 4½ Gallons

EE-40 5¼ Gallons

EE-60 7¾ 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.

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 140513) 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.

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.
