Equipment Description

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.

Operation

The operator controls kettle heating with the thermostat dial. The dial turns heating element 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.

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.

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.

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) 12” (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.

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 OVERFI

LL THE KETTLE WHEN COOKING, HOLDING OR CLEANING. KEEP

LIQUIDS AT LEAST 2-3” (5-8 cm) BELOW THE KETTLE RIM TO ALLOW CLEARA

NCE FOR STIRRING, BOILING

AND SAFE PRODUCT TRANSFER.

OM-DEE/4

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. 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.

Sequence of Operation

The following “action-reaction” outline is provided to help the user understand how the equipment works.

When the operator starts up the kettle by turning the operating thermostat dial from “OFF” to a desired setting, the thermostat switch closes. This lights up the heating 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 heating indicator light and causes the contactors to open, stopping the power to 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, the contactors close, 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 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 “OFF” shuts down all control and heating circuits.

OM-DEE/4

The pressure gauge should show a vacuum of 20 to 30 inches when the kettle is cold.

Test the safety valve at least twice monthly.

Maintenance

NOTICE: Contact Groen or an authorized Groen representative when repairs are required.

1. 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. 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:

[BY OPERATOR]

a. Check the pressure/vacuum gauge

every day. The gauge should show a vacuum of 20 to 30 inches, when the kettle is cold. If it does not, see “Jacket Vacuum” on page 13.

b. Also check the

jacket water level every day. It should be between the marks on the gauge glass. If the level is low, see “Jacket Filling and Water Treatment” on page 13.

c. Test the safety

valve at least twice each month. Test the valve with the kettle operating at 15 psi (105 kPa), 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 Groen service representative.

WARNING WHEN TESTING, AVOID ANY EXPOSURE TO THE STEAM BLOWING OUT OF THE SAFETY VALVE. DIRECT CONTACT COULD RESULT IN SEVERE BURNS.

[BY SERVICE TECHNICIAN]

d. Electrical wiring should be kept securely

connected and in good condition.

e. The inside of the support housing

should be kept clean.

OM-DEE/4

2. Jacket Vacuum

When the kettle is cold, a positive pressure/ vacuum gauge reading or a reading near zero indicates that there is air in the jacket. Air in the jacket 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 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.

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 this water, either because it was lost as steam during venting 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 step 4, “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.

CAUTION

BEFORE YOU HEAT THE KETTLE AGAIN FOR ANY PURPOSE, TURN THE ELBOW BACK CLOCKWISE UNTIL THE OPENING FACES DOWNWARD.

e. Air introduced to the jacket during filling

must be removed to obtain efficient heating. See “Jacket Vacuum” above.

4. Water Treatment Procedure

(1) Obtain water treatment compound and a

pH test kit from your authorized Groen parts distributor.

WARNING TO AVOID INJURY, READ AND FOLLOW ALL PRECAUTIONS STATED ON THE LABEL OF THE WATER TREATMENT COMPOUND.

(2) Fill a mixing container with the

measured amount of water required. (See table). Distilled water is recommended.

Kettle Model Jacket Capacity

DEE/4-20 2½ Gallons

DEE/4-40 3½ Gallons

DEE/4-60 4 Gallons

(3) Hang a strip of pH test paper on the rim

of the container, with about 1 inch of the strip below the surface of the water.

(4) Measure the water treatment compound

(One way to do this is to add the compound from a measuring cup.)

(5) Stir the water continuously, while you

slowly add water treatment compound, until the water reaches 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 pH 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.

(6) Record the exact amounts of water and

treatment compound used. These amounts may be used again, if the same water sources and compound are used in the future. However, it is best to check the pH each time treated water is prepared.

WARNING ELECTRIC POWER ALWAYS SHOULD BE SHUT OFF BEFORE WORK IS DONE ON INTERNAL COMPONENTS.

5. Service personnel should check the unit at least once a year. This periodic maintenance should include inspecting electrical wires and connections, cleaning the inside of the control console.

At least twice a year, grease the two trunnion bearings and worm gear. Groen recommends the use of number two grade LGI lithium grease. Add grease through the zerk fittings on the gear hosing until the grease flows out of the bearings around the trunion shaft. Also, add grease in the gear to cover arc that is in contact with the worm gear. Clean up excess grease.

WARNING DISCONNECT ELECTRICAL POWER FROM THE UNIT BEFORE ATTEMPTING TO GREASE THE TRUNION BEARINGS.
