The operator controls kettle heating with the
thermostat dial. The dial turns heating element
electric power on or off and sets the operating
temperature of the kettle.
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 below the lower
mark, see ?Jacket Filling and Water
Treatment? on page 13 of this manual.
2. Check the pressure gauge. If the gauge
does not show 20 to 30 inches of vacuum
(that is, areading of 20 to 30 below 0),
see ?Jacket Vacuum? on page 12 of this
manual.
3. Tum on the electrical power to the unit.
4. Tum the thermostat dial to the desired
setting. The heating indicator light shows
that the kettle is heating, and cycling of the
light on and off indicates that the ketile is
being held at the set temperature. Once in
each cycle the contactors in the support
housing will makeaclicking sound. This is
normal.
B. To Transfer Product or Empty Kettle:
The kettle is designed and manufactured to
be tilted in acontrolled manner. Grasp the
insulated plastic ball firmly. Maintain afirm
grip on handle when tilting, while keeping
kettle body in atilted position and when
SLOWLY retuming the kettle body to an
upright position. 7

C. To Shut Down Kettle
1. Tum the thermostat dial to ?OFF?.
2. For prolonged shut-down, or before
cleaning the outside of the unit, shut off
the power supply to the unit
D. Use of Common Accessories
1. Lift Off Cover.
As with stock pot cooking, an optional lift off
cover can speed heating of water and food
products. It helps retain heat in the cooking
vessel and reduces the heat and humidity
released into the kitchen. Use of acover can
reduce some product cook times and help
maintain the temperature, color and texture
of products being held or simmered for
extended periods.
Make sure plastic ball handle is secure on the
lift off cover before using. ALWAYS use the
plastic handle to place or remove the cover
from the kettle. Wear protective oven mitts
and a protective apron.
When putting the cover on the kettle, position
it on top of kettle rim, with its flat edge facing
the pouring lip.
Tao 0
When removing cover:
a) Firmly grasp the plastic handle
b) Lift rear edge (farthest from Operator) 1-2?
(3-5 cm) to allow any steam andwater
vapor to escape the cooking vessel. Wait
2-3 seconds.
C) Tilt cover to 45-60° angle and allow any
hot condensate or product to roll off cover
back into kettle.
d) Remove the 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 kettlerim.
CAUTION
DO NOT TILT KETTLE BODY WITH COVER
IN PLACE. COVER MAY SLIDE OFF,
CAUSING INJURY TO OPERATOR.
2. Basket Insert
An optional kettle basket insert can assist in
cooking boiled products, including eggs,
potatoes, vegetables, shellfish, pasta and rice.
The nylon mesh liner must be used when
cooking products smaller than the mesh size of
the basket, (approximately %4? (6 mm) such as
rice and small pasta shapes.
Tips For Use.
a) Allow for water displacement of basket
and product. This may mean only filling the
kettle half full of water. Test basket 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 2-3? (5-8 cm) BELOW THE
KETTLE BODY RIM TO ALLOW
CLEARANCE FOR STIRRING, BOILING
AND SAFE PRODUCT TRANSFER.

Sequence of Operation
The following ?action-reaction? outline is provided to
heip the user understand how the equipment
works.
When the operator starts up the kettle by tuming
the operating thermostat dial from ?OFF? to a
desired setting, the thermostat switch closes. This
jets power flow to the contactor coil. The coil then
activates the contactor, which sends powerto the
heating elements and indicator light. 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 stops 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, 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.
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 50 PSt is generated
in the jacket, the safety valve will open and relieve
the excess pressure.
In the event that the jacket water level gets too
low and the heating elements overheat, the low
water control will open and shut off power to the
elements. Setting the operating thermostat dial to
?OFF? shuts down ail control and heating circuits.

Maintenance
NOTICE: Contact Groen oran authorized Groen representative when repairs are required.
41. Periodic Maintenance
AMaintenance &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 efficiency of
operation. Check the following points:
a. Check the pressure/vacuum gauge every
day. The gauge should show avacuum of
20 to 30 inches, when the kettle is cold. if
The pressure gauge should show avacuum

it does not, see ?Jacket Vacuum? at right.
b. Also check jacket water level every day.
It should be between the ?minimum-
maximum? marks on the gauge glass. If
the level is low, see ?Jacket Filling and
Water Treatment? on page 13.
c. Ensure that wiring is securely connected
and in good condition.
d. Keep the inside of the support housing
clean.
®. Test the safety valve at least twice each
Month. Test the valve with the kettle
12
operating at five PSI by lifting the test
lever to release steam.
CONTACT
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, immediately discontinue
use of the kettle and contact aqualified
Groen service representative.
2. Jacket Vacuum
When the kettle is cold, apositive pressure
reading or areading near zero on the
pressure/vacuum gauge indicates air in the
jacket. This stows down heating of the kettle.
To remove air:
a. Start the unit. (See the ?Operation?
section of this manual.)
b. When the pressure/vacuum gauge
reaches apositive pressure reading of five
PSI, release the entrapped air and steam
by pulling up on the safety valve ring for
about 1second. Let the pull ring snap
back into the closed position. Repeat this
step immediately after the gauge again
reads five PSI.
ee

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 the water to its proper level,
either because water was lost as steam
during venting or because treated water was
lost by draining.
a. !f 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.i
CAUTION
BEFORE ATTEMPTING STEP [3b] VERIFY
THAT THE PRESSURE GAUGE SHOWS
ZERO OR AVACUUM. IF THE GAUGE
SHOWS AREADING HIGHER THAN ZERO
PSIG, RELIEVE THE PRESSURE BY
CAREFULLY PULLING THE SAFETY VALVE
RING.
b. Allow the kettle to cool completely. Tum
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 apoint between the
marks on the gauge glass.
CAUTION
BEFORE YOU HEAT THE KETTLE FOR ANY
PURPOSE, TURN THE ELBOW CLOCKWISE
UNTIL THE OPENING AGAIN FACES
DOWNWARD.
dg. Air introduced to the jacket during the
filling operation must be removed to
obtain efficient heating. See Jacket
Vacuumf on page 12.
4, Water Treatment Procedure
Riad A
ee
COMPOUND
13
OM/SM-TDB/6
Place one quart of water in the mixing
container. Distilled water is
recommended.
Hangastrip of pH test paper on the rim
of the container, with about 1inch of the
strip below the surface of the water.
Measure the water treatment compound
(Groen part number 110324) you will be
using. (One way to do this is to add the
compound from ameasuring cup.)
Stir the water continuously, while you
slowly add water treatment compound,
until the water reaches apH between
10.5 and 11.5. Judge the pH by
frequently comparing the color of the test
strip with the color chart provided in the
PH test kit. If you have difficult matching
colors, use an electro-analytical device to
check, or ask another person fo help you.
Record the exact amounts of water and
treatrnent compound used. These
amounts may be used again, if the same
sources of water and compound are
employed to refill the jacket in the future.
However, it is advisable to check the pH
every time treated water is prepared.
