2. In the USA, the National Electrical code, ANSI/NFPA-70 (latest edition). In Canada, the Canadian Electrical Code, Part 1, CSA Standard C22.1 (latest edition).

Installation Steps:

1. Set the kettle in the installation location.

2. With the kettle in position, place a carpenter’s level on top of the kettle and turn the adjustable feet to level the kettle side-to-side and front to back.

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

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

5. Reposition kettle. Re-level kettle by making necessary adjustments on flanged feet.

6. Bolt down kettle and seal with Silastic or other equivalent sealing compound. Sealant must be applied not only to bolt heads but also around flanges making contact with the floor surface to fulfill NSF requirements. Wipe off excess sealant immediately.

For electrical connections, a Control Box with a power supply equivalent to the electrical rating of the kettle should be located conveniently nearby. The kettle must be grounded in accordance with the National Electrical Code or applicable local codes.

The CROWN EL-30 is a self steam generating kettle with a jacket charged with a solution of water and antifreeze, sufficient to completely immerse and protect the replaceable electric heating elements.

When the Power Switch is turned ON and the Temperature Control (Thermostat) Knob is dialed, the TEMPERATURE pilot light will come on, and contactors will close to allow power to the elements. Steam generation will commence and continue until the water in the jacket reaches the preselected thermostatic temperature. At this point, the Temperature Control will de-energize, cutting off power to the heating elements, and the TEMPERATURE pilot light will go off. When the jacket water temperature drops slightly, the cycle repeats to maintain the selected cooking temperature.

The kettle jacket is sealed, and air has been removed at the factory. The Pressure Gauge should indicate a vacuum (in the green zone, approx. 25-30 inches Hg) when the kettle is cold. This vacuum seal should not be broken by tripping the safety relief valve during inoperative periods.

A Safety Probe is incorporated to sense water level depletion in the jacket. If the water level is too low, it will activate the LOW WATER indicator pilot light and signal the Liquid Level Control to switch off power to the heating elements, preventing burnout.

1. Ensure that the external electrical service to the CROWN EL-30 kettle is on.

2. Check the pressure gauge for the correct cold kettle reading. The reading should be in the green area of the gauge, indicating 25-30 In. Hg (630 – 730 mm Hg) of vacuum. If the reading is not low enough, follow the VENTING procedure in the Troubleshooting section before using the kettle.

3. Place the power switch to the ON position.

4. Preheat the kettle by placing the thermostat knob at ’10’ and wait until the TEMPERATURE light goes off. Preheating should not be used when cooking milk and egg food products which adhere to hot cooking surfaces. These foods should be placed into the kettle before heating has begun.

5. Add food to be cooked into the kettle.

6. Place the thermostat knob at the required temperature setting from 1 to 10. Refer to the temperature chart for approximate jacket temperatures.

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

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

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

Your CROWN EL-30 should be cleaned immediately after each use. Before cleaning, check that the kettle has cooled enough to touch it. Do not use cleaning agents that are corrosive.

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

2. Using a nylon brush, clean the kettle with a mild detergent and water. Never use steel wool or scouring powder as it will scratch stainless steel. Plain steel wool can leave small pieces of steel which can rust.

3. Rinse the inside of the kettle thoroughly with clean water. Drain the kettle using the tangent draw-off valve to allow the detergent and water solution to drain.

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

Ensure the kettle is completely empty of any product before cleaning the valve.

1. Turn the large hex nut on the draw-off valve counterclockwise until it is completely disengaged from the threads. Grasp the valve knob and slowly pull out the valve stem. Wash the valve stem, disk, and handle. Insert a nylon brush, wet with detergent and water, into the valve body and tangent draw-off tube. Brush vigorously.

2. Replace the valve stem assembly and turn the hex nut until snug. Rinse the kettle with clean warm water.

3. Leave the draw-off valve open when the kettle is not in use.

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

To remove surface accumulation of rust, which may be caused by scratching from metal utensils, follow this procedure:

1. Use undiluted white vinegar with a non-abrasive scouring pad (plastic) or cloth on the affected area to remove the rust stain. The appliance should not be heated and should remain at room temperature during the entire cleaning process.

2. If the stain resists removal, additional exposure time with vinegar may be required, up to a maximum of one hour.

3. Thoroughly wash all of the vinegar away with fresh clear water. Dry the surface completely and allow one hour before using the appliance to cook.

A “try lever test” should be performed every two months under normal operating conditions, or more often under severe service conditions or if corrosion/deposits are noticed. It should also be performed at the end of any non-service period.

CAUTION: Hot, high-pressure fluid may be discharged. High sound levels may be experienced. Wear proper safety equipment and exercise extreme care.

Test at, or near, half of the operating pressure by holding the test lever fully open for at least two seconds to flush the valve seat free of sediment and debris. Then release the lever and permit the valve to snap shut.

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

If water is below the required operating level, the CROWN EL-30 will automatically shut off and the LOW WATER signal light will come on. To restore operation, follow this procedure. The kettle must be cool before proceeding.

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

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

3. Insert a funnel into the Air Vent opening and slowly add the indicated amount of clean water from the table below.

4. Replace the air vent nut.

5. Follow the AIR VENTING INSTRUCTIONS.

6. Continue the normal operating procedure of the kettle.

If the cooking time on your CROWN EL-30 is abnormally slow, the difficulty may be due to air being present in the kettle jacket. To remove air, follow the AIR VENTING INSTRUCTIONS.

If the kettle will not reach and maintain the Pressure Gauge zone in the green area on the gauge when cold, a slow leak may have developed in the jacket. Check all fitting connections to the jacket including the heating element gasket. Tighten or replace if necessary.

Slow cooking time may also be due to a burnt out heating element. Test elements and if defective, replace the complete element assembly.

If your CROWN EL-30 will not operate, check the following:

1. Check that power supply is available to the kettle.

2. The kettle will not operate if the water level is inadequate in the jacket. Follow the LOW WATER LEVEL instructions to add water.

3. Check for a defective power switch or loose wire connections.

4. If the TEMPERATURE indicator light does not come on when the Thermostat Knob is dialed, it may be due to a defective Thermostat or loose wiring connection(s).

5. When the kettle is turned ON and the Thermostat Knob is dialed, check that the Contactors are being energized and power is being made available to the heating elements. Replace defective Contactors if necessary.

If a leak occurs through the valve stem on your CROWN EL-30, replace the “O” ring. If the leak is between the stem disc and valve seat, it may be due to dried-on food residue. Clean the dried-on food residue with an extremely fine emery cloth. If the rubber vulcanized stem piece has been damaged, it must be replaced.

Check the vacuum/pressure gauge when the CROWN EL-30 is cold. The gauge should be in the green vacuum zone. If not, air must be vented (removed) for proper heating. Use the following procedure to vent air:

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

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

3. Using a 7/16″ wrench, open the bleed vent one full turn for 10 seconds and then close. WARNING: Live steam will escape the bleed nut when opened. Stay clear of live steam when performing this operation.

4. Cool the kettle. Check for proper vacuum in the green vacuum zone. If the reading is not low enough, repeat the entire procedure, steps 1 – 4.
