The Groen DEE/4 is a floor-mounted, tilting, steam jacketed kettle with a
thermostatically controlled, selfcontained, electrically-heated steam supply and
appropriate controls, mounted on a sturdy base. The Model DEE/4 is available in 20,
40 or 60 gallon capacities.
The body of the DEE/4 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 345 kPa (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.
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 65.5°C (150°F) and as high as 148°C (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 high-limit pressure switch as safety features.
CE units have three lights on the Control Panel. The green POWER light comes on
when the unit is turned on. It indicates that power is being supplied to the unit. The
amber HEAT light comes on when heating elements are heating the kettle. The red
LOW WATER light will come on when water level in the jacket falls below acceptable

8 OM-DEE/4
Operation
CE units have three lights on the Control Panel. The green POWER light comes on
when the unit is turned on. It indicates that power is being supplied to the unit. The
amber HEAT light comes on when heating elements are heating the kettle. The red
LOW WATER light will come on when water level in the jacket falls below acceptable
operating levels. Refer to the section on Jacket Filling and Water Treatment (Page 14).
A. To Start Kettle
1. EVERY DAY make sure that the jacket water level is between the
markers on the gauge glass. If the level is too low, see “Jacket Filling
and Water Treatment” on page 14.
2. 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 atmospheric pressure),
see “Jacket Vacuum” on page 14.
3. Turn on the electrical power to the unit by setting the power switch to
ON. The green POWER indicator should light.
4. Turn the thermostat to desired setting. The amber HEAT indicator light
will come on. Cycling of the light on and off the shows that the kettle is
being held at the set temperature. Once in each cycle the contactors in
the support housing will make a clicking sound. This is normal.
B. To Transfer Product or Empty Kettle
1. The kettle is tilted by means of the crank on the front of the control
housing. The kettle remains in the position to which tilted until cranked
again.
2. Product may also be transferred by means of the optional draw-off valve
if the kettle is so equipped.
C. Common Accessories
1. LIft-Off Cover 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.

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.
e. Place cover on safe, flat, sanitary, out-of-the-way surface, or
return to kettle.
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”, 6mm). This includes rice and small pasta
shapes. Tips for use:
a. Allow for displacement of the three baskets and product. This
may mean only half filling the kettle. Test baskets and product
displacement with the kettle power switch and thermostat turned
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 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.

10 OM-DEE/4
Sequence of Operation
The following “action-reaction” outline is provided to help understand how the kettle
works.
When the operator starts up the kettle by turning on the power switch and by turning
the operating thermostat dial from “0” to a desired setting, the thermostat switch
closes and the green POWER lamp comes on. This also lights up the amber HEAT
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, stopping the power to the heaters.
As soon as the thermostat senses that the kettle is cooking 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 HEAT 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 345 kPa (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 operating thermostat dial to “0” shuts down the heating circuits. Turning
the power switch to OFF shuts down all heating and control circuits.

OM-DEE/4 11
Cleaning
A. Suggested Cleaning Supplies
1. Cleaner, such as Klenzade HC-10 or HC-32 from ECOLAB, Inc.
2. Kettle brushes in good condition.
3. Sanitizer such as Klenzade XY-12.
4. Film remover such as Klenzade LC-30.
B. Precautions
Before any cleaning operation, shut off the kettle by turning the thermostat
dial to “0” and the power switch to OFF, then shut off all electric power to the
unit at a remote switch, such as the circuit breaker.
C. 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 large amounts of 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, housing, electrical
conduit, etc.
4. Rinse the kettle thoroughly with hot water. Then drain completely.
5. Disassemble the tangent draw-off valve. Clean the draw-off port and
each valve part with a brush.
6. Rinse the kettle and draw-off valve parts thoroughly with hot water,
then drain completely.
7. When you reassemble the draw-off valve, HAND-TIGHTEN the nut
which holds it in place.
8. As part of the daily cleaning program, clean soiled external and
internal surfaces. Remember to check the sides of the unit and
control housing.
9. To remove burned-on foods, use a brush, sponge, cloth, plastic or
rubber scraper, or plastic wool along with the cleaning solution. To
reduce effort required in washing, let the detergent solution sit in the
kettle for a few minutes 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 will leave particles in
the surface and cause eventual corrosion and pitting.
10. The outside of the unit may be polished with a recognized stainless
steel cleaner or hot water and detergent.

Maintenance
NOTICE: Contact an authorized representative when repairs are required.
A Maintenance & Service Log is provided at the back of this manual. Each time
maintenance is performed on your 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:
1. Check the pressure/vacuum gauge everyday. The gauge should show a vacuum of
20 to 30 inches mercury (Hg), when the kettle is cold. If it does not, see “Jacket
Vacuum” on page 14.
2. Also check the jacket water level every day. It should be between the markers on
the gauge glass. If the level is low, see “Jacket Filling and Water Treatment” on
page 14.
3. Test the safety valve at least twice each month. Test the valve with the kettle
operating at 105 kPa (15 psi), by holding the test lever for at least 5 seconds. Then
release the lever and let the valve snap shut. If the lever does not activate, or there
is no evidence of discharge, or the valve leaks, stop using the kettle and contact a
qualified service representative.
4. Keep electrical wiring and connections in good condition.
5. Keep the inside of the control console clean and dry.
6. Safety Valve Operating Instructions
If adding water to a boiler, DO NOT ALLOW water to flow through safety valve as
sediment or debris may be deposited on seating surface.
To achieve topmost performance and maximum service life, it is necessary to
maintain a proper pressure margin between set pressure of the safety valve and
equipment operating pressure. The minimum required pressure margin for this type
of valve is 10% of the safety relief valve set pressure, but not less than 34.5 kPa
(5 psi). UNDER NO CIRCUMSTANCES SHOULD THIS MARGIN BE LESS THAN 34.5
kPa (5 psi). Failure to maintain this operating margin may result in water leakage
past the seat and an accumulation of deposits on the seating surface. Excessive
deposits may prevent the valve from operating properly, and a dangerous pressure
build-up and equipment rupture may result.
7. Lubrication (Gears)
The gear housing has fittings for proper lubrication of moving parts. Because the
gears do not run in oil, periodic lubrication with grease is necessary. Frequency of
lubrication will depend on operating conditions, but it should be performed at least
once every six months. It is recommended that a Number Two grade LGI lithium
grease be used. Add grease through the Zerk fittings on the gear housing until
grease flows out of the bearings around the trunnion shaft. Place a liberal amount
of grease on the gear to cover the arc that is in contact with the worm gear.
WARNING
WHEN TESTING, AVOID ANY EXPOSURE TO
THE STEAM BLOWING OUT OF THE SAFETY
VALVE. DIRECT CONTACT COULD RESULT IN
SEVERE BURNS.
WARNING
DISCONNECT ELECTRICAL POWER FROM
THE UNIT BEFORE ATTEMPTING TO
GREASE THE TRUNNION BEARINGS.
WARNING
TO AVOID INJURY, READ AND FOLLOW ALL
PRECAUTIONS STATED ON THE LABEL OF

8. 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
34.5 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.
9. 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.
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 “Water Treatment Procedure.”
b. Allow the kettle to cool. Turn the elbow on the safety valve counterclockwise
(to avoid thread damage) until the opening of the elbow faces upward.
c. Open the safety valve and pour the water or treated water in at the elbow
until the water level rises to a point between the marks on the gauge glass.
d. Air introduced to the jacket during filling must be removed to obtain
efficient heating. See “Jacket Vacuum.”
10. Water Treatment Procedure
a. Obtain water treatment compound and a pH test kit from your
authorized parts distributor.
b. Fill a mixing container with the measured amount of water required.
(See table). Use distilled water only.
c. Hang a strip of pH test paper on the rim of the container, with about
25 mm 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 treatment compound,
until the water has 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 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.
f. As you add water to the jacket, check water level to ensure that it
is between minimum and maximum marks on gauge. Stop adding water
when it reaches the maximum marker on the gauge.

g. Record the exact amounts of water and treatment compound needed.
These amounts may be used again, if the same water sources and
compound are used. However, it is best to check the pH each time
treated water is prepared.
11. Installation of Safety Valve
a. Installation must be performed by qualified service personnel only.
b. The BTU/hr or lb/hr rating of this valve must equal or exceed that of the
equipment to which it is attached
c. DO NOT use this valve on a coal or wood boiler having an uncontrolled
heat input.
d. Ensure that all connections, including the valve inlet, are clean and free
from any foreign material.
e. Use pipe compound sparingly, or tape, on external threads only.
f. DO NOT USE A PIPE WRENCH! Use proper type and size wrench on
wrench pads only.
g. This valve must be mounted in a vertical, upright position directly to a
clean, tapped opening in the top of the boiler or equipment. Under no
circumstances should there be a flow restriction or valve of any type
between the safety relief valve and the pressure vessel
h. WARNING! During operation, this valve may discharge large amounts
of steam and/or hot water. To reduce the potential for bodily injury and
property damage, a discharge line MUST be installed that:
1. is connected from the valve outlet with no intervening valve and
directed downward to a safe point of discharge.
2. allows complete drainage of both the valve and the discharge line
3. is independently supported and securely anchored so as to avoid
applied stress on the valve.
4. is as short and straight as possible.
5. terminates freely to atmosphere where any discharge will be
clearly visible and is at no risk of freezing.
6. terminates with a plain end that is not threaded.
7. is constructed of a material suitable for exposure to temperatures
of 174°C (375°F) or greater.
8. is, over its entire length, of a size equal to or greater than the
valve outlet.
i. Use only schedule 40 pipe for discharge. (Do not use schedule 80,
extra strong pipe or connections). DO NOT CAP, PLUG, OR OTHERWISE
OBSTRUCT DISCHARGE PIPE OUTLET!
j. See appropriate ASME Boiler and Pressure Vessel Code for additional
installation instructions.
