The Groen D Series are deep type, tilting kettles with direct steam-heated 2/3 jackets.
The stainless steel kettles have welded, reinforced rims and buttery shaped pouring
lips. The liner and pouring lip of all kettles are 316 stainless steel. They are ASME
shop-inspected, and are registered with the National Board. The kettles have a 180
emery grit interior finish and a bright semi-deluxe exterior finish.
Every unit requires a remote steam source. The steam supply is controlled by an
inlet valve, and enters the jacket through one trunnion directly into the jacket. Steam
pressure forces condensate out a dip tube through the other trunnion. Both steam and
condensate lines are concealed within the support structures of the various models.
The table to the left shows the standard kettle sizes for each model.
These kettles operate safely and efficiently at various steam pressures above five
PSI, with upper pressure limits assured by the provided safety valve. Operation also
requires a globe valve on the steam inlet and a strainer, steam trap, and check valve
on the condensate outlet. These may be ordered from Groen as optional equipment.
D Series kettles are emptied by tilting, but optional tangent draw-os are available. The
standard draw-off is two inch outer diameter stainless steel, with compression disc
valve and a removable stainless steel strainer that has 1/4 inch perforations. Strainers
with 1/8 inch or no perforations are also available. The table on the left shows the
sizes of draw-offs which can be furnished with each model. When equipped with a
tangent draw-off the designation “T” is added to the model designation.
The kettles in this series employ a worm and gear tilting mechanism, which is
completely enclosed.
D Series kettles are mounted in three ways. Model D is suspended in a stainless steel
yoke on a pedestal base. The outer circumference of the base is flanged down for
proper sealing to the floor. Model DL is supported by a tubular, stainless steel tri-leg
frame with adjustable floor flanges. The discontinued wall-mounted model MW/D had
a supporting frame enclosed in a stainless steel, drip-proof housing. The frame hung
on an in-wall carrier which was purchased as an option.
Other options include:
1. No. 31 lift-off cover (for kettles smaller than 60 gallons)
2. No. 51 cover with counter-balancing actuator (for 40 gallon and larger kettles)
3. Fill faucets with swing spout
4. Gallon Master water meter
5. TRI-BC basket cooking system
6. Kettle brush kit
7. Operating pressures up to 90 PSIG

CAUSE INJURY TO PERSONNEL AND/OR
DAMAGE TO EQUIPMENT.
1. Installation under a ventilation hood is recommended. Consult local codes.
2. Install and anchor the kettle on a level surface.
3. If the steam supply pressure is greater than the maximum working pressure
stamped on the nameplate, you must install a pressure reducing valve in the steam
supply line near the kettle.
4. Connect the steam supply line to the steam inlet fitting. Include a steam control
valve and an appropriate safety valve. To obtain the full heating capability of the
kettle, the steam supply line must be as large as the steam inlet fitting.
5. The safety valve is preset to relieve jacket pressure that exceeds its rated limit. Do
not try to adjust the valve setting, and do not allow the valve outlet or lever to be
blocked.
6. Connect the kettle condensate return line to the boiler return line, or to a drain.
A suitable steam trap, strainer, and check valve must be installed on the left side
kettle trunnion (viewed from the front). (See piping diagram, Page 19).
7. Any mechanical change must be approved by the Groen Food Service Engineering
Department.
For proper sanitation, continuous seal is
required between pedestals or flanges

SEVERE BURNS. TAKE CARE TO AVOID
CONTACT WITH HOT KETTLE BODY OR HOT
PRODUCT. WHEN ADDING INGREDIENTS,
STIRRING OR TRANSFERRING PRODUCT
TO ANOTHER CONTAINER.
Before operating a cold kettle, open the petcock at the bottom of the jacket to drain
any water left by condensing steam. Close the petcock before you open the steam
inlet valve. Draining this water decreases the “hammering” you hear when steam
enters a cold jacket.
To heat the kettle, open the steam inlet valve. Adjusting the inlet valve allows the
operator to control the heating rate. Opening the valve more allows steam to flow into
the jacket faster, and thereby heats the product faster.
The kettle operates efficiently with steam pressures from five PSI to the maximum
working pressure for which the kettle was designed. The maximum allowable
pressure is stamped on the kettle nameplate. It is 25 PSI for standard units.
Once a day, while there is still steam pressure in the jacket, bleed off any entrapped
air and double check the operation of the safety valve. Pull out on its chain, or lift the
lever far enough to let steam escape. Then let it snap back into place to reseat the
valve so that it will not leak.
TILTING THE KETTLE:
To transfer product or empty the kettle: turn the handwheel counterclockwise. The
kettle will hold its position when you stop turning the wheel. If the tilting mechanism
seems to be locked, do not use force to free the kettle. Call for assistance from your
Groen Certified Service Agency, or refer to the Troubleshooting section of this manual.

A. Suggested Cleaning Supplies
1. A high quality detergent and sanitizer, or a combination cleaning sanitizing agent.
2. Kettle brushes in good condition.
3. Brush suitable for cleaning the tangent draw-off port (if kettle has optional
tangent).
4. Use a good sanitizer
5. Film remover
B. Procedure
1. Clean food-contact surfaces as soon as possible after use. If the unit is in continuous use, thoroughly clean and sanitize the interior and exterior at least once
every 12 hours.
2. Scrape and flush out food residues. Be careful not to scratch the kettle with
metal implements.
3. Prepare a hot solution of the detergent/ cleaning compound as instructed by the
supplier.
4. Clean the unit thoroughly, inside and outside.
5. Rinse the kettle thoroughly with hot water, then drain completely.
6. As part of the daily cleaning program, clean soiled external and internal surfaces.
7. To remove stuck materials, use a brush, sponge, cloth, plastic or rubber scraper,
or plastic wool with the cleaning solution. To reduce effort required in washing, let the detergent solution sit in the kettle 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 may leave particles in the surface and cause eventual
corrosion and pitting.
8. The outside of the unit maybe polished with a stainless steel cleaner such as
“Zepper” from Zep Manufacturing Co.
9. 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. Drain
and thoroughly rinse off the sanitizer.
10. It is recommended that each piece of equipment be sanitized just before use.
11. If there is difficulty removing mineral deposits or a film left by hard water or
food residues, clean the kettle thoroughly and use a deliming agent, like Groen
Delimer/Descaler (Part Number 114800), in accordance with the manufacturer’s
directions. Rinse and drain the unit thoroughly before further use.

NOTICE: Contact an authorized representative when repairs are required.
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. File the log with the warranty.
Periodic inspection will minimize equipment down time and increase the efficiency of
operation. The following points should be checked:
1. Once a day, with pressure in the jacket, check the operation of the safety valve. Lift
the lever of the safety valve until steam is released. 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 a qualified Groen
service representative.
2. At least once every 90 days, inspect fittings and valves for signs of damage or wear.
Regularly examine trunnion packings and valve seats for wear, and replace them when
necessary.
NOTE: Service performed by other than factoryauthorized personnel will void all
warranties.
3. Lubricate trunnions and gears with a good grade of high temperature grease. Grease
trunnions at least once every 60 days, and grease gears when inspection shows that
they are dry.
4. If the kettle cover has an actuator, lubricate it every 90 days.
NOTE: Use only Calcium Complex Nr. 2 Grease, which is available from Groen (Part No.
093703).

Page 13
Sequence of Operation
The following “action-reaction” outline is provided to help the user understand the
function of the equipment.
When the steam inlet valve is opened, steam flows into the jacket at a pressure
determined by the boiler system or by the pressure reducing valve that serves the
kettle.
In the jacket, steam transfers heat to the kettle as it condenses into water. The steam
trap allows condensate (water) to leave the jacket, while it holds steam in. When the
steam is shut off, condensation produces a vacuum in the jacket, but the check valve
in the condensate return line keeps water from flowing back into the jacket.
OM-D 13
