   a. EVERY DAY make sure that the jacket water level in the middle of the sight glass. If the level is too low, see “Jacket Filling and Water Treatment” in this manual.
   b. Check the pressure/vacuum gauge. If the gauge does not show 20 to 30 inches of mercury (Hg) vacuum (that is a reading of 20 to 30 below 0 atmospheric pressure),  see “Jacket Vacuum” in this manual.
   c. DO NOT attempt to light any burner with a flame.
   d. Open the main supply gas valve (handle in line with the pipe).
   e. Turn the switch to ON.
   f. Set heat using instructions above.

2. To Stop Kettle Heating:
   a. Turn the switch OFF.
   b. Turn the manual gas valve OFF (handle a right angle to gas line).
   c. Disconnect the units electrical power.

3. To Relight Kettle:
   a. Close main gas supply valve.
   b. Set on-off switch to OFF.
   c. Wait five minutes, then proceed as directed under To Start Kettle Heating.

4. If electric power fails, do not attempt to operate the unit. When power is restored, proceed as directed in To Start Kettle Heating.

5. To Transfer Product or Empty Kettle:
   a. To tilt the body of the kettle forward, turn the hand crank on the front of the cabinet counter-clockwise. The body will stay in the position it holds when you stop  cranking. To return the kettle body to its upright position, turn the crank clockwise.
   b. Product may also be transferred by means of the optional draw-off valve, if the kettle is so equipped.

USE OF COMMON ACCESSORIES

1. Lift-Off or Counterbalanced Cover:
   a. As with stock pot cooking, an optional cover can speed up the heating of water and food products. It helps retain heat and reduces the heat and humidity in the  kitchen. A cover can reduce some product cook times and help maintain the temperature, color and texture of products held or simmered for longer periods.
   b. 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 apron.
   c. When putting the cover on the kettle, position it on top of kettle rim, with its flat edge facing the pouring lip.
   d. When removing cover:

1. Firmly grasp plastic handle.
2. Lift rear edge (farthest from operator) 1-2” (3-5 cm) to allow any steam and water vapor to escape the cooking vessel. Wait 2-3 seconds.
3. Tilt cover to 45-60° angle and allow any hot condensate or product to roll off cover back into kettle.
4. Remove cover, ensuring that any remaining hot condensate or product does not drip on operator, floor or work surfaces.
5. Place cover on safe, flat, sanitary, out-of-the-way surface, or return to kettle rim.

2. Basket Insert:
   a. An optional kettle basket insert can assist in cooking water-boiled products including eggs, potatoes, vegetables, shell fish, pasta and rice. The nylon mesh liner must be  used when cooking product smaller than the mesh size of the basket, which is approximately 1/4” (6 mm). This includes rice and small pasta shapes.
   b. Tips For Use:

1. Allow for the water displacement of the basket and product to be cooked. This may mean only filling the kettle half full of water. Test the basket and product  displacement with the kettle OFF, and with cold water in the kettle.
2. Load basket on a level, stable work surface.
3. Lift the loaded basket with both hands. Get help from another personif the basket is too heavy for safe handling. Then slowly lower productinto kettle.
4. When removing basket with cooked product, lift basket straight up,ensuring bottom of basket clears the rim and pouring lip of the kettle.Wear protective oven mitts and protective apron.
5. Allow hot water to fully drain from product, before moving basketaway from the kettle. Do not rest kettle basket on kettle rim or pouringlip. If basket is too heavy for individual to lift and safely move, get helpfrom another person. Remove product immediately from basket intoanother container, being sure to avoid contact with hot  product andhot basket or place basket with food on stable, flat surface, setting itinside a solid steamer or bake pan, to catch any remaining hot waterdraining from  product.

CLEANING

WARNING: KEEP WATER AND SOLUTIONS AWAY FROM CONTROLS AND ELECTRICAL EQUIPMENT. NEVER SPRAY THE SUPPORT HOUSING OR ELECTRICAL CONNECTIONS.
CAUTION: MOST CLEANERS ARE HARMFUL TO THE SKIN, EYES, MUCOUS MEMBRANES, AND CLOTHING. PRECAUTIONS SHOULD BE TAKEN. WEAR RUBBER GLOVES, GOGGLES OR FACE SHIELD, AND PROTECTIVE CLOTHING. READ THE WARNINGS AND FOLLOW THE DIRECTIONS ON THE LABEL OF THE CLEANER CAREFULLY.
CAUTION: NEVER LEAVE A SANITIZER IN CONTACT WITH STAINLESS STEEL SURFACES LONGER THAN 30 MINUTES. LONGER CONTACT CAN CAUSE CORROSION.
CAUTION: DO NOT MIX PARTS OF DIFFERENT DRAWOFF VALVE ASSEMBLIES. THE PARTS ARE NOT INTERCHANGEABLE.
WARNING: AVOID DIRECT CONTACT WITH HOT SURFACES. DIRECT SKIN CONTACT COULD RESULT IN SEVERE BURNS.

SUGGESTED CLEANING SUPPLIES

1. Cleaner, such as Klenzade HC-10 or HC-32 from ECOLAB, Inc. or equivalent.
2. Kettle brushes in good condition
3. Sanitizer such as Klenzade XY-12.
4. Film remover such as Klenzade LC-30.

PRECAUTIONS
Before cleaning, shut off the kettle by turning the main power switch to “OFF,” and shut off all electric power to the unit at a remote switch, such as the circuit breaker.
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. (For DHT models only: After flushing the kettle, close the draw-off valve.)

3. Prepare a hot solution of the detergent/ cleaning compound as instructed by the supplier. Clean the unit thoroughly. A cloth moistened with cleaning solution can be used to clean controls, housings, and electrical conduits.

4. Model DHT only: Disassemble the tangent draw-off valve. Clean the draw-off port and each valve part with a brush.

5. Rinse the kettle and draw-off valve parts thoroughly with hot water, then drain completely.

6. As part of the daily cleaning program, clean soiled external and internal surfaces. Remember to check the sides of the unit and control housing, underside of cover, etc.

7. To remove burnt on foods, 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 may be cleaned with a warm water (100°F or less) spray. Do not use a high pressure spray.

9. The outside of the unit may be polished with a stainless steel cleaner such as “Zepper” from Zep Manufacturing Co.

10. 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.

11. It is recommended that each piece of equipment be sanitized just before use.

12. Clean the kettle thoroughly. If there is difficulty removing mineral deposits or a film left by hard water or food residues, then use a de-liming agent, following manufacturer directions.

13. Rinse and drain the unit thoroughly before further use.

14. If cleaning problems persist, contact your cleaning product representative for assistance. The supplier has a trained technical staff with laboratory facilities to serve you.

CLEANING CORE PROBE
Remove all food soil from core probe by wiping entire core probe and cable assembly with warm detergent solution and a clean cloth. Remove detergent solution by wiping  core probe and cable assembly with clean rinse water and a cloth. Allow core probe and cable assembly to air dry. Do not immerse core probe.
Hand wash only and immediately let air dry.

MAINTENANCE

WARNING: AVOID ANY EXPOSURE TO THE STEAM BLOWING OUT OF THE PRESSURE RELIEF VALVE. SEVERE BURNS CAN RESULT ON  EXPOSED SKIN. FAILURE TO CHECK PRESSURE RELIEF VALVE OPERATION PERIODICALLY COULD RESULT IN PERSONAL INJURY AND/OR  DAMAGE TO EQUIPMENT.
CAUTION: KEEP GREASE AWAY FROM ELECTRICAL PARTS LOCATED NEAR THE GEARS.
WARNING: TO AVOID INJURY, READ AND FOLLOW ALL PRECAUTIONS STATED ON THE LABEL OF THE WATER TREATMENT COMPOUND.
WARNING: USE OF ANY REPLACEMENT PARTS OTHER THAN THOSE SUPPLIED BY THE MANUFACTURER OR THEIR AUTHORIZED  DISTRIBUTORS CAN CAUSE INJURY TO THE OPERATOR AND DAMAGE TO THE EQUIPMENT AND WILL VOID ALL WARRANTIES.
CAUTION: INSURE ELECTRICAL POWER IS REMOVED AND THE GAS IS TURNED OFF AT THE SHUTOFF VALVE PRIOR TO PERFORMING ANY  MAINTENANCE ON THIS KETTLE.
WARNING: THIS KETTLE IS DESIGNED TO BE WATER RESISTANT. FAILURE TO FOLLOW PROPER MAINTENANCE PROCEDURES MAY VOID THE WARRANTY.

PERIODIC MAINTENANCE
NOTICE: Contact an authorized representative when repairs are required.
A Maintenance & Service Log is provided at the back of this manual. Each timemaintenance is performed on your 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 andincrease the efficiency of  operation. The following points should be checked:

1. Check the pressure/vacuum gauge every day. The gauge should show a vacuum of 20 to 30 inches mercury (Hg), when the kettle is cold. If it does not, see “Jacket  Vacuum” in this manual.
2. Also check the jacket water level every day. It should be in the middle of the sight glass. If the level is low, see “Jacket Filling and Water Treatment” in this manual.
3. Carefully test the pressure relief valve at least twice each month. With the kettle operating at five psi (105 kPa), pull the test lever and let it snap back to its closed  position. If there is little discharge (mostly air), and the pressure gauge drops back to zero PSI, allow the pressure to build back to five PSI and repeat the procedure.  (Tip: Using a screwdriver or other implement to pull the ring will help you avoid contact with the steam.)
4. If the valve 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.
5. Keep the primary burner gas jet air inlets free of dust and lint.
6. The pilot flame should be blue. It should envelop about ½ inch (12 mm) of the flame sensor tip.
7. The gear housing has fittings for lubrication of moving parts. The gears do not run in oil, so periodic lubrication with grease is necessary.
8. Frequency of lubrication depends on operating conditions, but it should be done at least once every six months.
9. Use a #2 grade LGI lithium grease to add grease through Zerk fittings on gear housing until it flows out of the bearings around the trunnion shaft.
10. Place liberal amounts of grease on the gear to cover the arc that is in contact with the worm gear.
11. Keep electrical wiring and connections in good condition.
12. Keep the inside of the control console clean and dry.
13. Keep burner slots clean.

JACKET VACUUM/REMOVING AIR FROM JACKET
When the kettle is cold, a positive pressure reading on the pressure/vacuum gauge or a reading near zero indicates that there is air in the jacket. Air in the jacket acts as an  insulator, and slows kettle heating.
To remove air:

1. Start the unit. (Be sure there is water or product in the kettle when heating).
2. When the pressure/vacuum gauge reaches a positive pressure reading of five PSI, release the trapped air and steam by pulling up the safety valve ring for about five  seconds. Repeat this step three or four times. Then let the pull ring snap back into the closed position.
3. If there is little discharge (mostly air), and the pressure gauge drops back to zero PSI, allow the pressure to build back to five PSI and repeat the procedure.
4. Once steam has been vented from the jacket as described in b, above, remove the hot water from the kettle and replace it with cold. This will condense steam in the  kettle jacket, and the pressure gauge should show a reading of 20 to 30 inches mercury (Hg) below zero. If it does not, or if the vacuum is leaking down, contact a Groen  authorized service agency to correct the problem.

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 venting steam or by draining. 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 “Water Treatment Procedure,” below.

1. Allow the kettle to cool completely. The procedure will be easier with the kettle under vacuum (pressure gauge reading below zero).
2. Make sure the fill valve is closed, and remove the square head pipe plug with open-ended wrench.
3. Position a funnel in the opening and fill it with properly treated water.
4. Slowly open the fill valve to allow water to be sucked into the jacket. Quicklyclose the valve to prevent air from entering.
5. Check water level in the jacket to ensure that it is between minimum andmaximum marks on glass or at the top of the sight glass port for models DH/DHT-80.
6. Close the valve and reinstall the squarehead pipe plug.
7. Reestablish the jacket vacuum as described above, if the pressure gauge doesnot show a negative reading of 20 to 30 inches mercury (Hg).

WATER TREATMENT PROCEDURE

1. Obtain water treatment compound and a pH test kit from your Groen Service Agent.

2. Fill a mixing container with the measured amount of water required. Use only distilled water.
   Model| Recommended Jacket Fill
   ---|---
   DH-20(C,A,C2T)| 1-3/4 gallons
   DH-25(C,A,C2T)| 1-3/4 gallons
   DH-30(C,A,C2T)| 1-1/2 gallons
   DH-40(C,A,C2T)| 1-1/2 gallons
   DH-60(C,A,C2T)| 3 gallons
   DH-80(C,A,C2T)| 3 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 treatment compound, until the water has 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 test kit.
   Caution: Do not add excess amount of treatment compound. Excess amount could cause extensive corrosion.

6. As you add water to the jacket, check water level to ensure that it is between minimum and maximum marks on glass or at the top of the sight glass port for models  DH/DHT-80 (see photo on page 8). Stop adding water when it reaches the maximum marker on the gauge.

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

COMPONENT REPLACEMENT
When component replacement involves breaking a gas pipe connection, check the new connection with soap solution or an appropriate leak detector. DO NOT USE A  FLAME TO TEST FOR LEAKS.
Internal wiring is marked as shown on the circuit schematic drawings (inside control housing and in this manual). Be sure that new components are wired in the same manner  as old components. An examination of the circuit schematic shows that the safety components are wired in series. In most cases, a faulty component may be isolated with a  jumper wire to verify that the component is faulty. If this determination is made, contact a certified Groen Service Agency for assistance.

SEQUENCE OF OPERATION
The following “action-reaction” outline is provided to help understand how the kettle works.

1. When the power switch is turned on, it starts the spark igniter and opens the automatic valve for the pilot burner. The spark ignites a pilot flame, which heats the sensor.  The sensor then sends a signal to turn off the spark. The flame thereafter acts as a standing pilot until the power is turned off.
2. If the pilot flame is not sensed within 90 seconds after spark begins, a timer shuts down the entire operation. To attempt a second trial for ignition, turn off the power  switch. Check the gas supply valves and wait five minutes before trying again by switching power on. If you cannot establish a pilot flame in four tries, close all valves,  turn off the power, and contact an authorized Service Agency.
3. When the operator sets a temperature on the controller, it causes the automatic valve to admit gas to the main burner, where it is ignited by the pilot flame. When the  kettle reaches the set temperature, the relay switch opens. This stops the signal to the gas control valve and shuts off gas to the main burner. The pilot flame remains lit.  When the kettle cools below the set temperature, the relay switch closes and starts another cycle. On and off cycling continues and maintains the kettle at the desired  temperature. This action is indicated by the Heat indicator light.

The kettle has the following safety features in addition to the 90-second ignition timer:

1. Low water cutoff relay that will shut off gas supplies to all burners until the jacket water level is corrected.
2. High limit pressure switch, set to open at about 43 PSI and to shut down the burners until jacket pressure is decreased.
3. Pop safety valve, which will release steam if jacket pressure exceeds 50 PSI.
4. Tilt switch, which shuts off all burners when the kettle is tilted.
5. Gas pressure regulator built into the gas control valve.
