CROWN EP-30 (01) PDF Document

To operate your CROWN EP-30, follow these steps:

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 use.

3. Place the power switch to the ON position.

4. Preheat the kettle by setting 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 begins.

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 setting table 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 it thoroughly.

The thermostat settings on the CROWN EP-30 correspond to the following approximate jacket temperatures:

Your CROWN EP-30 kettle should be cleaned immediately after each use. Before cleaning, ensure the kettle has cooled enough to touch.

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.

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.

Warning: If you are cleaning a valve that is assembled to a kettle, be sure the kettle is completely empty of any product.

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.

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.

To remove surface accumulation of rust from the inadvertent use of metal utensils, follow this procedure. 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 must 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. This test 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.

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 is below the required operating level, the kettle will automatically shut off and the LOW WATER light will come on. To fix this, 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. For the CROWN EP-30, add 150 ounces (4.44 litres). If the jacket is completely empty, add 504 ounces (14.90 litres).

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 or the vacuum/pressure gauge is not in the green vacuum zone when cold, air must be vented (removed) for proper heating. Follow these steps:

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 it.

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

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

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

2. Check if the water level is adequate in the jacket. If not, follow the LOW WATER LEVEL instructions.

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, the malfunction may be due to a defective Thermostat or loose wiring. If the light does come on, the kettle should eventually reach its maximum temperature.

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 the draw-off valve on your CROWN EP-30 is leaking, follow these steps:

1. If the leak occurs through the valve stem, replace the “O” ring.

2. 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.

3. If the rubber vulcanized stem piece has been damaged, it must be replaced.
