Equipment Description

OM-DEE/4

The Groen DEE/4 is a floor-mounted, tilting,
steam jacketed kettle with a thermostatically
controlled, self-contained, 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
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 high­limit pressure switch as safety features. A
heating indicator light, pressure gauge, and sight
glass are provided for monitoring kettle
operation.

A single electrical connection is required for
installation. The unit may be ordered for use with
208/240, 400 or 480 volt power. All kettles are
wired for three-phase operation. Single-phase
units are also available.

The unit will arrive in a heavy shipping carton
and will be bolted or banded to a skid.
Immediately upon receipt, inspect the carton
carefully for exterior damage.

CAUTION
SHIPPING STRAPS ARE UNDER TENSION
AND CAN SNAP BACK WHEN CUT. TAKE
CARE TO AVOID PERSONAL INJURY OR
DAMAGE TO THE UNIT BY STAPLES LEFT
IN THE WALLS OF THE CARTON.

Carefully cut any polyester straps around the
carton and detach the sides of the box from the
skid. Pull the carton up off the unit.

Thoroughly inspect the unit for concealed
damage. Report any shipping damage or
incorrect shipments to the delivery agent.

Write down the model number, serial number,
and installation date, and retain this information
for future reference. Space for these entries is
provided at the top of the Service Log at the
back of this manual. Keep this manual on file
and available for operators to use.

CAUTION
THIS UNIT IS VERY HEAVY. INSTALLER
SHOULD OBTAIN HELP AS NEEDED TO
LIFT THIS WEIGHT SAFELY.

When installation is to begin, carefully cut any
straps which hold the unit on the skid. Lift the
unit straight up off the skid. Examine packing
materials to be sure loose parts are not
discarded with the materials.

Installation

OM-DEE/4

The Groen Kettle is provided with complete
internal wiring and is ready for immediate
connection. Wiring diagrams are provided in this
manual and on the inside of the control housing
service panel. Any mechanical or electrical
changes must be approved by Groen’s Food
Service Engineering Department.

WARNING
INSTALLATION OF THE KETTLE MUST BE
DONE BY PERSONNEL QUALIFIED TO
WORK WITH ELECTRICITY. IMPROPER
INSTALLATION CAN RESULT IN INJURY
TO PERSONNEL AND/OR DAMAGE TO
EQUIPMENT.

The completed unit has been operated at the
factory to test all controls and heater elements.

1. Set the kettle in place and level it by turning
the bullet feet to adjust leg length. Allow
clearance around the unit for cleaning,
maintenance and service.

2. Confirm that the jacket water level is above
the mid point of sight glass (new models) or
between the marks on the gauge glass (old
models). If the level is low, follow the
instructions under “Jacket Filling and Water
Treatment,” Page 13.

3. The open end of the
elbow on the outlet of
the safety valve must
face downward. If it
does not, turn it to
the correct position.

4. Provide electrical
power specified on
the equipment electrical information plate.
Observe local codes and/or The National
Electrical Code in accordance with
ANSI/NFPA 70 - (current edition).

5. The equipment is shipped ready for three
phase operation. Refer to the wiring diagram
for single phase operation.

6. Bringing the electrical service through the
entrance at the rear of the support housing
with one inch conduit, making a watertight
connection with the incoming lines. Observe
local codes and/or the National Electrical
Code in compliance with ANSI/NFPA 70
(latest edition). When there is a choice
between applicable codes, Groen
recommends following the more stringent
code. (A BX connection is not
recommended.)

DANGER
ELECTRICALLY GROUND THE UNIT AT
THE TERMINAL PROVIDED. FAILURE TO
GROUND UNIT COULD RESULT IN
ELECTROCUTION AND DEATH.

7. Electrically ground the unit at the terminal
provided.

8. Check the following to confirm that your
DEE/4 kettle is properly installed:

• Room for cleaning and servicing

• The kettle is level

• The correct amount of water is in the

kettle jacket

• Safety valve is pointed down

• Unit is connected with a waterproof

supply of the proper voltage, phase and
amperage rating

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 1-2 quarts 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.

5. To shut down the unit, turn the thermostat
dial to “OFF”.

If the unit functions as described above, it is
ready for use. If the unit does not function as
described, contact your local Groen Certified
Service Agency.

Each day, confirm the jacket water level by checking
the water gauge.

power on or off and sets the kettle operating
temperature.

A. To Start 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 13.

Operation

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 2-3” (5-8 cm) BELOW
THE KETTLE BODY RIM TO ALLOW
CLEARANCE FOR STIRRING, BOILING
PRODUCT AND SAFE TRANSFER.

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

13.

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.

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 transfered by
means of the optional draw-off valve if
the kettle is so equipped.

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
