Equipment Description
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 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
ELECTRICAL SUPPLY CONNECTION REQUIREMENTS
into the jacket. “Airless” operation of the steam jacket
permits uniform, efficient heating at temperatures as
low as 150°F and as high as 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
“POWER” light comes on when the unit is turned on.
It indicates that power is being supplied to the unit.
The “HEAT” light comes on when heating elements
are heating the kettle. The “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 12).
A single electrical connection is required for
installation. The unit may be ordered for use with 230
VAC, 1 Phase, 50 Hz, or 400 VAC, 3 Phase, 50 Hz
power.

Section 2 - Initial Start-Up
IMPORTANT:
BE SURE ALL OPERATORS READ, UNDERSTAND AND FOLLOW THE OPERATING INSTRUCTIONS,
CAUTIONS AND SAFETY INSTRUCTIONS CONTAINED IN THIS MANUAL.
Now that the kettle has been installed, you
should test it to ensure that the unit is operating
correctly.
1. Remove all literature and packing materials
from inside and outside of the unit.
2. If the unit is equipped with a draw-off valve
(product outlet), clean out any material which
might clog or damage the draw-off.
3. Confirm that the tilting mechanism is
operating properly by tilting the kettle
through its full range. Then return the kettle
to the upright position.
4. Turn on the electrical service to the unit.
5. Pour 2-4 liters of water into the kettle.
6. Following “To Start Kettle” instructions in the
“Operation” section of this manual, begin
heating the water at the highest thermostat
setting. The heating indicator light should
come on immediately, and heating should
continue until the water boils.
WARNING
AVOID ALL DIRECT CONTACT WITH HOT
SURFACES. DIRECT SKIN CONTACT
COULD RESULT IN SEVERE BURNS.
AVOID ALL DIRECT CONTACT WITH HOT
FOOD OR WATER IN THE KETTLE. DIRECT
CONTACT COULD RESULT IN SEVERE
BURNS.

Section 3 - Operation
CE units have three lights on the Control Panel. The
“POWER” light comes on when the unit is turned on. It
indicates that power is being supplied to the unit. The
“HEAT” light comes on when heating elements are
heating the kettle. The “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 12).
3.1 Starting Kettle
1. EVERY DAY make sure that 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.
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), see “Jacket
Vacuum” on page 12.
3. Turn on the electrical power to the unit.
4. Turn the thermostat dial to the desired setting.
The heating indicator light indicates 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 the
contactors in the support housing will make
a clicking sound. This is normal.
2. Product may also be transfered by means of the
optional draw-off valve if the kettle is so equipped.
WARNING
AVOID ALL DIRECT CONTACT WITH HOT SURFACES.
DIRECT SKIN CONTACT COULD RESULT IN SEVERE
BURNS.
AVOID ALL DIRECT CONTACT WITH HOT FOOD OR
WATER IN THE KETTLE. DIRECT CONTACT COULD
RESULT IN SEVERE BURNS.
TAKE SPECIAL CARE TO AVOID CONTACT WITH HOT
KETTLE BODY OR HOT PRODUCT, WHEN ADDING
INGREDIENTS, STIRRING OR TRANSFERRING
PRODUCT TO ANOTHER CONTAINER.
CAUTION
DO NOT OVERFILL THE KETTLE WHEN COOKING,
HOLDING OR CLEANING. KEEP LIQUIDS AT LEAST 23” (5-8 cm) BELOW THE KETTLE BODY RIM TO
ALLOW CLEARANCE FOR STIRRING, BOILING
PRODUCT AND SAFE TRANSFER.
WARNING
WHEN TILTING KETTLE FOR PRODUCT TRANSFER:
1) WEAR PROTECTIVE OVEN MITT AND PROTECTIVE
APRON.
2) USE DEEP CONTAINER TO CONTAIN AND MINIMIZE
PRODUCT SPLASHING.
3) PLACE CONTAINER ON STABLE, FLAT SURFACE, AS
CLOSE TO KETTLE AS POSSIBLE.
4) STAND TO LEFT OR RIGHT OF KETTLE WHILE
POURING — NOT DIRECTLY IN POUR PATH OF HOT
CONTENTS.
5) POUR SLOWLY, MAINTAINING CONTROL OF KETTLE
AT ALL TIMES, AND RETURN KETTLE BODY TO
UPRIGHT POSITION AFTER CONTAINER IS FILLED
OR TRANSFER IS COMPLETE.
6) DO NOT OVERFILL CONTAINER. AVOID DIRECT SKIN
CONTACT WITH HOT CONTAINER AND ITS
CONTENTS.
3.2 Transferring Product/Emptying 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.

OM/SM-DEE (CE)
CAUTION
KEEP FLOORS IN FRONT OF THE KETTLE WORK
AREA CLEAN AND DRY. IF SPILLS OCCUR, CLEAN
AT ONCE TO AVOID SLIPS OR FALLS.
3.3 Common Accessories
1. Lift-Off 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.
CAUTION
DO NOT TILT KETTLE WITH LIFT-OFF COVER IN
PLACE. COVER MAY SLIDE OFF, CAUSING INJURY
TO OPERATOR.
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” (6
mm). This includes rice and small pasta shapes.
Tips For Use.
a) Allow for displacement of the 3 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
AVOID ALL DIRECT CONTACT WITH HOT
SURFACES. DIRECT SKIN CONTACT COULD
RESULT IN SEVERE BURNS.
AVOID ALL DIRECT CONTACT WITH HOT FOOD OR
WATER IN THE KETTLE. DIRECT CONTACT COULD
RESULT IN SEVERE BURNS.
When removing the lift-off cover:
a) Firmly grasp the handle
b) Lift rear edge (farthest from operator) 1-2” (3-5
cm) to allow steam and water vapor to escape
the cooking vessel. Wait 2-3 seconds.
c) Tilt cover to 45-60° angle to allow any hot
condensate or product 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.
WARNING
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.
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 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.
