• Improper installation, adjustment, alteration, service, or maintenance can cause property damage, injury, or death. Read all instructions thoroughly before use.

• The kettle and its parts are hot during and after use. Use care when operating, cleaning, and servicing.

• Do not store or use gasoline or other flammable vapors or liquids near this or any other appliance.

• Keep the appliance area free and clear from combustible materials.

• Do not obstruct the flow of combustion and ventilation air.

• Do not attempt to operate the CROWN EL-100 during a power failure.

• This product is intended for commercial use only and is not for household use.

• If you smell gas, follow the instructions provided by your local gas supplier, which should be posted in a prominent location.

• Contact the factory, a factory representative, or a local service company for maintenance and repairs if the appliance malfunctions.

Follow these steps to properly install your CROWN EL-100 kettle:

1. The kettle must be installed in accordance with all state and/or local codes, as well as the National Electrical Code, ANSI/NFPA-70 (in the USA) or the Canadian Electrical Code, Part 1, CSA Standard C22.1 (in Canada).

2. Set the kettle in its final installation location.

3. Place a carpenter’s level on top of the kettle. Turn the adjustable feet to level the kettle from side-to-side and front-to-back.

4. Mark the hole locations on the floor through the anchoring holes provided in the flanged adjustable feet.

5. Carefully move the kettle and drill holes in the marked locations. Insert proper anchoring devices to accommodate 5/16″ size lag bolts (not supplied).

6. Reposition the kettle over the anchors and re-level it by making necessary adjustments to the flanged feet.

7. Bolt the kettle down securely. To fulfill NSF requirements, seal the unit by applying Silastic or an equivalent sealing compound to the bolt heads and around the flanges where they make contact with the floor. Wipe off any excess sealant immediately.

A Control Box with a power supply equivalent to the electrical rating of the CROWN EL-100 should be located conveniently nearby. Follow these steps for connection:

1. Disconnect the electrical power supply and place a tag at the disconnect switch to indicate you are working on the circuit.

2. Remove the wiring compartment cover on the kettle’s control housing.

3. Make electrical connections according to the wiring diagram located inside the control housing cover panel. A waterproof electrical connection must be provided from the power supply to the rear of the control housing.

4. The CROWN EL-100 must be grounded in accordance with the National Electrical Code or applicable local codes. Ground the kettle to the terminal provided in the control housing.

5. Once all connections are properly made, replace the wiring compartment cover.

6. Turn the power ON and check for proper operation.

The CROWN EL-100 features a double-wall construction that forms a sealed chamber, or jacket, around the lower two-thirds of the kettle bowl. This jacket is a self-contained system filled with a permanent solution of water and antifreeze.

When you turn the power switch ON and set the temperature dial, electricity flows to the heating elements immersed in this solution. The elements heat the solution, generating steam within the sealed jacket. This pressurized steam transfers heat evenly and efficiently to the surface of the kettle bowl, cooking the food product inside.

The thermostat monitors the temperature and cycles the heating elements on and off to maintain your preselected cooking temperature precisely. When the kettle is cold, the pressure gauge should indicate a vacuum (in the green zone), which shows the jacket is properly sealed. A built-in low-water safety system will shut off power to the elements if the water level in the jacket drops, preventing damage to the unit.

1. Ensure that the external electrical service to the kettle is on.

2. Check the pressure gauge for the correct cold kettle reading. The needle should be in the green area of the gauge, indicating 25 – 30 In. Hg of vacuum. If the reading is not low enough, follow the VENTING procedure before use.

3. Place the power switch in the ON position.

4. Preheat the kettle by setting the thermostat knob to ’10’. Wait until the TEMPERATURE light goes off. Note: Preheating should not be used when cooking milk and egg products that adhere to hot surfaces. These foods should be placed in the kettle before heating begins.

5. Add the food to be cooked into the kettle.

6. Place the thermostat knob at the required temperature setting, from 1 to 10.

7. When cooking is complete, set the thermostat knob and power switch to the OFF position.

8. Empty the product from the kettle using the draw-off valve, being careful to avoid splashing.

9. Add water to the kettle for cleaning purposes and wash it thoroughly.

The thermostat settings from 1 to 10 on your CROWN EL-100 correspond to the following approximate temperatures within the kettle’s steam jacket:

Your CROWN EL-100 should be cleaned immediately after each use. Before cleaning, disconnect the power supply and ensure the kettle has cooled enough to touch.

Kettle Cleaning:

1. Rinse the inside of the kettle thoroughly and drain to remove any loose food particles.

2. Using a nylon brush, clean the kettle with a mild detergent and water. Never use steel wool or corrosive/abrasive cleaning agents, as they can scratch and damage the stainless steel.

3. Rinse the inside of the kettle thoroughly with clean water, and drain completely using the draw-off valve.

4. Wipe the exterior of the kettle with a clean, damp cloth.

Draw-Off Valve Cleaning:

1. Make sure the kettle is completely empty of any product.

2. Turn the large hex nut on the draw-off valve counterclockwise until it is completely disengaged from the threads.

3. Grasp the valve knob and slowly pull out the valve stem. Wash the stem, disk, and handle.

4. Insert a nylon brush, wet with detergent and water, into the valve body and tangent draw-off tube. Brush vigorously.

5. Replace the valve stem assembly and turn the hex nut until snug. Do not over tighten, as this may damage the rubber-coated stem.

6. Rinse the kettle and valve with clean warm water.

7. It is recommended to leave the draw-off valve open when the kettle is not in use.

Surface rust can appear if metal utensils scratch the stainless steel surface. To remove surface accumulation of rust, follow this procedure carefully. Improper use may damage your appliance.

1. Ensure the CROWN EL-100 is not heated and remains at room temperature throughout the cleaning process.

2. Apply undiluted white vinegar to the affected area using a non-abrasive scouring pad (plastic) or a soft cloth to remove the rust stain.

3. If the stain resists removal, you may need to allow the vinegar to sit on the area for an extended period, up to a maximum of one hour.

4. After the rust is removed, thoroughly wash all of the vinegar away with fresh, clear water.

5. Dry the surface completely and allow it to air out for one hour before using the appliance for cooking.

A “try lever test” should be performed every two months under normal operating conditions, and more often under severe service conditions or if corrosion is noticed. Be aware that hot, high-pressure fluid may be discharged from the valve during the test; exercise extreme care, wear proper safety equipment, and avoid any bodily contact.

1. Operate the kettle until it reaches approximately half of its normal operating pressure.

2. Hold the test lever on the safety valve fully open for at least two seconds. This action is designed to flush the valve seat free of any sediment and debris.

3. Release the lever and permit the valve to snap shut.

If the lift lever does not activate, or if there is no evidence of discharge from the valve, turn off the equipment immediately and contact a licensed contractor or qualified service personnel for assistance.

The LOW WATER light indicates that the water level in the jacket is below the required operating level, and the kettle will automatically shut off. To resolve this, the water must be replenished. The kettle must be cool before proceeding.

1. Trip the safety relief valve lever to relieve any and all pressure from the kettle jacket.

2. At the exterior rear of the kettle jacket, locate the Air Vent and remove the nut.

3. Insert a funnel into the Air Vent opening and slowly add the indicated amount of clean water according to the table below. The amount depends on if you are topping off or filling from empty.

4. Replace the air vent nut securely.

5. After adding water, you must perform the AIR VENTING procedure.

6. Once venting is complete, you can continue with the normal operating procedure of the kettle.

Abnormally slow cooking time in your CROWN EL-100 can be due to a few issues:

• Air in the Jacket: The most common cause is air being present in the kettle jacket, which hinders efficient heat transfer. To remove the air, follow the “AIR VENTING INSTRUCTIONS”.

• Slow Leak: If the kettle does not reach and maintain a vacuum (green zone on the gauge) when it is cold, a slow leak may have developed in the jacket. Check all fitting connections to the jacket, including the heating element gasket. Tighten any loose fittings or replace them if necessary.

• Burnt-out Heating Element: Slow heating can also be caused by a failed heating element. The elements should be tested by a qualified technician, and if one is found to be defective, the complete element assembly should be replaced.

If your CROWN EL-100 fails to operate, follow these troubleshooting steps:

1. Power Supply: Check that the main power supply to the kettle is available and turned on.

2. Water Level: The kettle will not operate if the water level in the jacket is inadequate. Check if the LOW WATER light is on and follow the instructions for adding water if necessary.

3. Power Switch/Wiring: Check for a defective power switch or any loose wire connections within the control housing.

4. Thermostat: If you dial the Thermostat Knob and the TEMPERATURE indicator light does not come on, the malfunction could be a defective thermostat or a loose wiring connection to it.

5. Contactors: When the kettle is turned ON and the Thermostat Knob is dialed, check that the contactors are being energized and that power is being made available to the heating elements. If the contactors are not functioning, they may need to be replaced by a qualified technician.

If the draw-off valve on your CROWN EL-100 is leaking, the cause determines the solution:

• Leak through the valve stem: If the leak occurs around the valve stem where you turn the handle, the “O” ring inside needs to be replaced.

• Leak from the valve seat (not sealing): If the leak is occurring because the valve is not sealing properly when closed, it may be due to dried-on food residue between the stem disc and the valve seat. Clean the dried residue off with an extremely fine emery cloth. If the rubber vulcanized piece on the stem has been damaged, it must be replaced.

NOTICE: The draw-off valve has a vulcanized rubber-coated stem for better sealing. Do not over tighten the valve, as this may cause the rubber to pull away from the stem and permanently damage it. This type of damage is not covered under warranty.

You should vent your CROWN EL-100 if the vacuum/pressure gauge does not read in the green vacuum zone when the kettle is cold. This procedure removes trapped air for proper heating.

WARNING: SCALD HAZARD. Live steam will escape the bleed nut when it is opened. Stay clear of the live steam when performing this operation.

1. With the kettle empty, place the power switch in the ON position.

2. Set the temperature control thermostat to its highest setting, ’10’. Heat the kettle until the indicator light goes off.

3. Using a 7/16″ wrench, carefully open the bleed vent one full turn for exactly 10 seconds, and then close it securely.

4. Allow the kettle to cool down completely. Once cool, check the gauge for a proper vacuum reading in the green vacuum zone. If the reading is still not low enough, you must repeat the entire procedure, steps 1 – 4.
