g. Place baskets with food on a stable, flatsurface, inside a solid steamer or bake pan,to catch any remaining hot water drainingfrom product.

Sequence of OperationThe following “action-reaction” outline is provided tohelp understand how the DH kettle works.

1. When the power switch is turned on, it starts thespark igniter and opens the automatic valve forthe pilot burner. The spark ignites a pilot flame,which heats the sensor. The sensor then sendsa signal to turn off the spark. The flamethereafter acts as a standing pilot until the poweris turned off.

2. If the pilot flame is not sensed within 90 secondsafter spark begins, a timer shuts down the entireoperation. To attempt a second trial for ignition,turn off the power switch. Check the gas supplyvalves and wait five minutes before trying againby switching power on. If you cannot establish apilot flame in four tries, close all valves, turn offthe power, and contact an authorized GroenService Agency.

3. When the operator sets a temperature on thethermostat, it causes the automatic valve to

admit gas to the main burner, where it is ignitedby the pilot flame. When the kettle reaches theset temperature, the thermostat switch opens. This stops the signal to the gas control valve andshuts off gas to the main burner. The pilot flameremains lit. When the kettle cools below the settemperature, the thermostat switch closes andstarts another cycle. On and off cyclingcontinues and maintains the kettle at the desiredtemperature. This action is indicated by the Heatindicator light.

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

1. Low water cutoff relay that will shut off gassupplies to all burners until the jacket water levelis corrected.

2. High limit pressure switch, set to open at about46 PSI and to shut down the burners until jacketpressure is decreased.

3. Pop safety valve, which will release steam ifjacket pressure exceeds 50 PSI.

4. Tilt switch, which shuts off all burners when thekettle is tilted.

5. Gas pressure regulator built into the gas controlvalve.

The pressure gauge should show a vacuum of20 to 30 inches of mercury (Hg) and the waterlevel should be between the markers when thekettle is cold. For water level on models DH/DHT-80, see photo on page 8.

MaintenanceNOTICE: Contact Groen or an authorized Groen Service Agent when repairs are required.

1. Periodic Maintenance

A Maintenance & Service Log is provided at theback of this manual with the warrantyinformation. Each time maintenance isperformed on your Groen kettle, enter the dateon which the work was done, what was done,and who did it. Keep this manual on file andavailable for operators to use.

Periodic inspection will minimize equipmentdown time and increase the efficiency ofoperation. The following points should bechecked:

a. Check the pressure/vacuum gauge everyday. The gauge should show a vacuum of

20 to 30 inches mercury (Hg), when thekettle is cold. If it does not, see “JacketVacuum” on page 13.

b. Also check the jacket water level every day. It should be between the markers on thegauge glass or inside the sight glass port. Ifthe level is low, see “Jacket Filling and Water Treatment” on page 13.

c. Test the safety valve at least twice eachmonth. With the kettle operating at five psi(105 kPa), pull the test lever and let it snapback to its closed position. If there is littledischarge (mostly air), and the pressuregauge drops back to zero PSI, allow thepressure to build back to five PSI and repeatthe procedure. (Tip: Using a screwdriver orother implement to pull the ring will help youavoid contact with the steam.)

d. If the valve does not activate, or there is noevidence of discharge, or the valve leaks,stop using the kettle and contact a qualifiedGroen service representative.

WARNINGWHEN TESTING, AVOID ANY EXPOSURE TOTHE STEAM BLOWING OUT OF THE SAFETYVALVE. DIRECT CONTACT COULD RESULT INSEVERE BURNS.

e. Keep the primary burner gas jet air inletsfree of dust and lint.

f. The pilot flame should be blue. It shouldenvelop about ½ inch (12 mm) of the flamesensor tip.

g. The gear housing has fittings for lubricationof moving parts. The gears do not run in oil,so periodic lubrication with grease isnecessary.

h. Frequency of lubrication depends onoperating conditions, but it should be done atleast once every six months.

i. Use a #2 grade LGI lithium grease to addgrease through Zerk fittings on gear housinguntil it flows out of the bearings around thetrunnion shaft.

j. Place liberal amounts of grease on the gearto cover the arc that is in contact with the

worm gear.

k. Keep electrical wiring and connections ingood condition.

l. Keep the inside of the control console cleanand dry.

m. Keep burner slots clean.

2. Jacket Vacuum/Removing Air from Jacket

When the kettle is cold, a positive pressurereading on the pressure/vacuum gauge or areading near zero indicates that there is air in thejacket. Air in the jacket acts as an insulator, andslows kettle heating.

To remove air:

a. Start the unit. (Be sure there is water orproduct in the kettle when heating).

b. When the pressure/vacuum gauge reachesa positive pressure reading of five PSI,release the trapped air and steam by pullingup the safety valve ring for about fiveseconds. Repeat this step three or fourtimes. Then let the pull ring snap back intothe closed position.

c. If there is little discharge (mostly air), and thepressure gauge drops back to zero PSI,allow the pressure to build back to five PSIand repeat the procedure.

d. Once steam has been vented from the jacketas described in b, above, remove the hotwater from the kettle and replace it with cold. This will condense steam in the kettle jacket,and the pressure gauge should show areading of 20 to 30 inches mercury (Hg)below zero. If it does not, or if the vacuum isleaking down, contact a Groen authorizedservice agency to correct the problem.

3. Jacket Filling and Water Treatment

The jacket was charged at the factory with theproper amount of treated water. You may needto restore this water, either because it was lostas venting steam or by draining. If you arereplacing water lost as steam, use distilled water.If you are replacing treated water that ran out ofthe jacket, prepare more treated water asdirected in “Water Treatment Procedure,” below.

Allow the kettle to cool completely. Theprocedure will be easier with the kettle undervacuum ( pressure gauge reading below zero).

(ONLY ONDH-60 ANDSMALLER)

OM-DHa. Make sure the fill valve is closed, and

remove the square head pipe plug withopen-ended wrench.

b. Position a funnel in the opening and fill itwith properly treated water.

c. Slowly open the fill valve to allow water to besucked into the jacket. Quickly close thevalve to prevent air from entering.

d. Check water level in the jacket to ensure thatit is between minimum and maximum markson glass or at the top of the sight glass port formodels DH/DHT-80 (see photo on page 8).

e. Close the valve and reinstall the square-head pipe plug.

f. Reestablish the jacket vacuum as describedin Paragraph 2, above, if the pressure gaugedoes not show a negative reading of 20 to30 inches mercury (Hg).

4. Water Treatment Procedure

a. Obtain water treatment compound and a pHtest kit from your Groen Service Agent.

WARNINGTO AVOID INJURY, READ AND FOLLOW ALLPRECAUTIONS ON THE LABEL OF THEWATER TREATMENT COMPOUND.

b. Fill a mixing container with the measuredamount of water required. (See table).Distilled water is recommended.

Kettle Model RecommendedJacket Fill

DH-20, DHT-20 2½ Gallons

DH/1-40, DHT/1-40 3½ Gallons

DH-60, DHT-60 4 Gallons

DH-80, DHT-80 1 1/4 Gallons*

c. Hang a strip of pH test paper on the rim ofthe container, with about 1 inch of the stripbelow the surface of the water.

d. Measure the water treatment compound. One way to do this is to add the compoundfrom a measuring cup.

e. Stir the water continuously, while you slowlyadd treatment compound, until the water hasa pH between 10.5 and 11.5. Judge the pHby frequently comparing the test strip colorwith the color chart provided in the test kit.

f. As you add water to the jacket, check waterlevel to ensure that it is between minimumand maximum marks on glass or at the top ofthe sight glass port for models DH/DHT-80 (seephoto on page 8). Stop adding water when itreaches the maximum marker on the gauge.

g. Record the exact amounts of water andtreatment compound needed. Theseamounts may be used again, if the samewater sources and compound are used.However, it is best to check the pH eachtime treated water is prepared.

5. Component Replacement

WARNINGBEFORE REPLACING ANY PARTS,DISCONNECT THE UNIT FROM THE ELECTRICPOWER SUPPLY AND CLOSE THE MAIN GASVALVE. ALLOW FIVE MINUTES FORUNBURNED GAS TO VENT.

When component replacement involves breaking agas pipe connection, check the new connection withsoap solution or an appropriate leak detector. DONOT USE A FLAME TO TEST FOR LEAKS.

Internal wiring is marked as shown on the circuitschematic drawings (inside control housing and inthis manual). Be sure that new components arewired in the same manner as old components. Anexamination of the circuit schematic shows that thesafety components are wired in series. In mostcases, a faulty component may be isolated with ajumper wire to verify that the component is faulty. Ifthis determination is made, contact a AuthorizedGroen Service Agency for assistance.

Cleaning

1. Suggested Cleaning Supplies:

a. Cleaner, such as Klenzade HC-10 or HC-32from ECOLAB, Inc. or equivalent.

b. Kettle brushes in good condition.c. Sanitizer such as Klenzade XY-12.

d. Film remover such as Klenzade LC-30.

2. Precautions

Before cleaning, shut off the kettle by turning thethermostat dial to “OFF,” and shut off all electricpower to the unit at a remote switch, such as thecircuit breaker.

WARNINGKEEP WATER AND SOLUTIONS AWAY FROMCONTROLS AND ELECTRICAL EQUIPMENT.NEVER SPRAY THE SUPPORT HOUSING ORELECTRICAL CONNECTIONS.

CAUTIONMOST CLEANERS ARE HARMFUL TO THESKIN, EYES, MUCOUS MEMBRANES, ANDCLOTHING. PRECAUTIONS SHOULD BETAKEN. WEAR RUBBER GLOVES, GOGGLESOR FACE SHIELD, AND PROTECTIVECLOTHING. READ THE WARNINGS ANDFOLLOW THE DIRECTIONS ON THE LABELOF THE CLEANER CAREFULLY

3. Procedure

a. Clean food-contact surfaces as soon aspossible after use. If the unit is in continuoususe, thoroughly clean and sanitize theinterior and exterior at least once every 12hours.

b. Scrape and flush out food residues. Becareful not to scratch the kettle with metalimplements. (For DHT models only: Afterflushing the kettle, close the draw-off valve.)

c. Prepare a hot solution of the detergent/cleaning compound as instructed by thesupplier. Clean the unit thoroughly. A clothmoistened with cleaning solution can beused to clean controls, housings, andelectrical conduits.

d. Model DHT only: Disassemble the tangentdraw-off valve. Clean the draw-off port andeach valve part with a brush.

CAUTIONDO NOT MIX PARTS OF DIFFERENT DRAW-OFF VALVE ASSEMBLIES. THE PARTS ARENOT INTERCHANGEABLE.

e. Rinse the kettle and draw-off valve partsthoroughly with hot water, then draincompletely.

f. When you reassemble the draw-off valve,hand-tighten the nut which holds it in place.

g. As part of the daily cleaning program, clean

soiled external and internal surfaces.Remember to check the sides of the unit andcontrol housing.

h. To remove burnt on foods, use a brush,sponge, cloth, plastic or rubber scraper, orplastic wool with the cleaning solution. Toreduce effort required in washing, let thedetergent solution sit in the kettle and soakinto the residue. Do NOT use abrasivematerials or metal tools that might scratchthe surface. Scratches make the surfaceharder to clean and provide places forbacteria to grow.

Do NOT use steel wool, which may leaveparticles in the surface and cause eventualcorrosion and pitting.
