CROWN EP-25 (01) PDF Document

The CROWN EP-25 kettle must be installed in accordance with state and/or local codes, and the relevant national electrical codes.

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 use shims to level the kettle side-to-side and front to back.

3. Mark hole locations on the floor through the anchoring holes provided on the pedestal base.

4. 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).

5. Reposition the kettle. Re-level the kettle by making necessary adjustments with shims.

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

A Control Box with a power supply equivalent to the electrical rating of the CROWN EP-25 should be located conveniently nearby.

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 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.

The CROWN EP-25 is a pressure vessel with a double-wall construction that forms a sealed jacket enveloping the lower two-thirds of the kettle bowl. This jacket is charged with a solution of water and antifreeze that completely immerses the electric heating elements.

When the Power Switch is turned ON and the Temperature Control (Thermostat) Knob is set, the TEMPERATURE pilot light will turn on, and power will flow to the heating elements. This generates steam within the sealed jacket. Steam generation continues until the water in the jacket reaches the preselected temperature. At this point, the thermostat de-energizes the heating elements, and the TEMPERATURE pilot light turns off.

When the temperature in the jacket drops slightly, the cycle repeats itself to maintain the selected cooking temperature. The higher the temperature, the greater the steam pressure in the jacket, resulting in a quicker cooking process.

The kettle jacket is sealed under a vacuum at the factory, which is indicated by the pressure gauge in the green vacuum zone when the kettle is cold. A Safety Probe is incorporated to detect a low water level in the jacket, which will activate the LOW WATER indicator light and shut off power to the heating elements to prevent damage.

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 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. 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.

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 EP-25 should be cleaned immediately after each use. Before cleaning, check that the kettle has cooled enough to touch it.

1. Disconnect the power supply to the appliance before cleaning.

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

3. 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.

4. 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.

5. 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.

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.

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 occur from the use of 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.

Normal Cleaning: To remove normal dirt, grease, or product residue from stainless steel, 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.

Grease and Food Splatters: To remove baked-on grease and food splatters, apply cleanser to a damp cloth or sponge and rub the cleanser on the metal in the direction of the polishing lines. Rub as gently as possible. NEVER RUB WITH A CIRCULAR MOTION.

Stubborn Deposits: Soil and burn deposits that do not respond to the above procedure can usually be removed by rubbing 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.

Heat Tint: Darkened areas from excessive heat can normally be removed by the above procedures. If the tint persists, it requires a vigorous scouring in the direction of the polish lines using SCOTCH-BRITE™ or STAINLESS scouring pads in combination with a powdered cleanser.

Control Panel: The textured control panel should be cleaned with warm water and mild soap. Never use an abrasive cloth or steel wool. Never use 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. Hot, high-pressure fluid may be discharged, so care must be taken to avoid bodily contact. Wear proper safety equipment.

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 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. To restore operation, follow these steps with the kettle cool:

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 is abnormally slow, the difficulty may be due to air being present in the kettle jacket. To remove air, follow 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.

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.

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

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

5. If 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 from faulty sealing 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 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. Live steam will escape; stay clear 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.
