• Keep the appliance area free and clear from combustibles.

• DO NOT obstruct the flow of combustion and ventilation air.

• Adequate clearances MUST be maintained for servicing and proper operation.

• Contact the factory, the factory representative, or a local service company to perform maintenance and repairs should the appliance malfunction. Refer to warranty terms.

Follow these steps to properly install your CROWN EL-25:

1. The kettle must be installed in accordance with state and/or local codes, and 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).

2. Immediately after unpacking, check for possible shipping damage. If the kettle is found to be damaged, save the packaging material and contact the carrier within 15 days of delivery.

3. Set the kettle in the installation location.

4. 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. On EP models, use shims to level the kettle.

5. Mark hole locations on the floor through the anchoring holes provided in the flanged adjustable feet, or holes provided on the pedestal base.

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

7. Reposition the kettle. Re-level the kettle by making necessary adjustments on the flanged feet or shims.

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

Before beginning, disconnect the electrical power supply and place a tag at the disconnect switch to indicate you are working on the circuit.

1. A Control Box with a power supply equivalent to the electrical rating of the kettle should be located conveniently nearby.

2. Remove the wiring compartment cover and make electrical connections per the wiring diagram located inside the control housing cover panel. A waterproof electrical connection from the power supply to the rear of the control housing must be provided.

3. The kettle must be grounded in accordance with the requirements of the National Electrical Code or applicable local codes. Ground the kettle to the terminal provided in the control housing.

4. Once proper connections are made, replace the wiring compartment cover, turn the power ON, and check for proper operation.

All internal wiring for the kettle is complete. If a faucet is provided, connect the water supply and check for proper operation.

Follow these instructions to operate your CROWN EL-25:

1. Ensure that the external electrical service to the 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 prior to 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. Note: 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, coinciding with the temperature table.

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 it thoroughly.

Your CROWN EL-25 should be cleaned immediately after each use. Before cleaning, disconnect the power supply and check that the kettle has cooled enough to touch it. Do not use cleaning agents that are corrosive. Never spray water into electric controls or components.

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 the 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.

Before cleaning the valve, be sure the kettle is completely empty of any product.

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

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

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

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

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

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

1. Remove the plug by first removing the handle, then turn the plug to line up with the pin and pull with both hands. It is important to use both hands because the plug is heavy.

2. Put the plug in a plastic pail that contains a mild soap solution. A plastic pail works best, as it reduces the possibility of nicking or scratching the plug. If the plug gets scratched it may not seal correctly and could leak.

3. Use a soft cloth or soft brush and clean all surfaces.

4. Using both hands remove the valve from the soap and rinse well in another plastic pail that contains fresh water.

5. Wash out the kettle as normal.

6. Once the kettle is washed out, return the plug into the body. Be sure the plug is inserted into the notch and turned. Ensure the plug is tight and secure before letting go of it.

If you are cleaning a body and plug assembly, remove the plug and follow the above procedures. When finished with the plug, follow the same instructions for washing the body. Always use both hands when handling the plugs. Reassemble the plug into the body and use as normal.

Metal utensils should never be used as they will scratch the surface of the equipment and rust may begin to form. To remove surface accumulation of rust from the inadvertent use of such utensils, the following procedure may be used. Improper use of this procedure may damage your appliance.

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, 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.

Stainless Steel Surfaces:

• To remove normal dirt, grease, or product residue, use ordinary soap and water (with or without detergent) applied with a sponge or cloth. Dry thoroughly with a clean cloth. Never use vinegar or any other corrosive cleaner.

• To remove grease and food splatters or condensed vapors that have baked on, apply cleanser to a damp cloth or sponge and rub the cleanser on the metal in the direction of the polishing lines. NEVER RUB WITH A CIRCULAR MOTION.

• For soil and burn deposits that do not respond to the above, rub the surface with SCOTCH-BRITE™ scouring pads or STAINLESS scouring pads in the direction of the polish lines. DO NOT USE ORDINARY STEEL WOOL, a wire brush, scraper, file, or other steel tools.

• To remove heat tint (darkened areas from excessive heat), use the cleaning methods above. For stubborn tint, a vigorous scouring in the direction of the polish lines using SCOTCH-BRITE™ pads or a STAINLESS scouring pad with a powdered cleanser may be necessary.

Control Panel:

• The textured control panel should be cleaned with warm water and mild soap. Never use an abrasive cloth, steel wool, or cleaning solvents with a hydrocarbon base.

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. Hot, high-pressure fluid may be discharged, so care must be taken to avoid bodily contact. High sound levels may be experienced; wear proper safety equipment.

1. 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.

2. 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 the water level in the jacket is below the required operating level, the kettle will automatically shut off and the LOW WATER signal light will come on. 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 with the normal operating procedure of the kettle.

Abnormally slow cooking time 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 in the green zone 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 the elements and if defective, replace the complete element assembly.

If your kettle does not operate, check the following:

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

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

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

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

• If the TEMPERATURE indicator light comes on when the Thermostat Knob is dialed fully to ’10’, the kettle should eventually reach its maximum temperature (290F) and a corresponding pressure reading of approximately 40 psi (on kettles rated at 50 psi).

• 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, replace the “O” ring. If the leak is due to faulty sealing between the stem disc and valve seat, it may be caused by 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 kettle 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. WARNING: Live steam will escape the bleed nut when opened. Stay clear of 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 ’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.

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.
