Installation Instructions

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) or in Canada, the Canadian Electrical Code, Part 1, CSA Standard C22.1 (latest edition).

2. Set the kettle in the installation location.

3. With the kettle in position, place a carpenter’s level on top of the kettle. For EP models, use shims to level the kettle side-to-side and front-to-back.

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

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

6. Reposition the kettle. Re-level the kettle by making necessary adjustments on the shims.

7. 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.

Electrical Connections

WARNING: 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 power ON and check for proper operation.

The CROWN EP-80 consists of a jacket charged with a solution of water and antifreeze sufficient to completely immerse and protect 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 temperature. At that point, the Temperature Control will de-energize, cutting off power to the heating elements, and the TEMPERATURE pilot light will go off. The cycle repeats as the temperature drops slightly, maintaining a precise cooking temperature.

The Pressure Gauge should indicate a vacuum in the jacket (in the green vacuum zone, approx. 25-30 inches Hg) when the kettle is cold. It is advisable not to trip the safety relief valve during inoperative periods as this will break the vacuum seal and allow air into the jacket.

The Temperature Controls have a high limit temperature setting to prevent the steam pressure from exceeding the rated working pressure. If the control fails, a Safety Valve will blow to release steam and lower the water level. A Safety Probe will then sense the low water level, activate the LOW WATER indicator light, and signal the Liquid Level Control to switch off power to the heating elements, preventing burnout.

WARNING: The kettle and its parts are hot. Use care when operating, cleaning and servicing the kettle.

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.

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.

NOTICE: 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 following 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.

WARNING: Disconnect the power supply to the appliance before cleaning or servicing. Never spray water into electric controls or components! The equipment and its parts are hot. Use care when operating, cleaning and servicing. CAUTION: Do not use cleaning agents that are corrosive.

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

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.

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

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

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

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

CAUTION: Improper use of this procedure may damage your appliance! Metal utensils should never be used as they will scratch the surface and rust may begin to form.

To remove surface rust, follow this procedure:

1. Use undiluted white vinegar with a non-abrasive scouring pad (plastic) or cloth on the affected area. 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.

Stainless Steel Care

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 baked-on grease and food splatters, apply cleanser to a damp cloth or sponge and rub in the direction of the polishing lines. NEVER RUB WITH A CIRCULAR MOTION.

For stubborn deposits, use SCOTCH-BRITE™ or STAINLESS scouring pads. DO NOT USE ORDINARY STEEL WOOL, as particles left on the surface will rust. NEVER USE A WIRE BRUSH, STEEL SCOURING PADS (EXCEPT STAINLESS), SCRAPER, FILE OR OTHER STEEL TOOLS.

TO REMOVE HEAT TINT: Darkened areas from excessive heat can normally be removed by vigorous scouring in the direction of the polish lines using SCOTCH-BRITE™ or a STAINLESS scouring pad 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.

CAUTION: Under normal operating conditions a “try lever test” should be performed every two months. Under severe service conditions, or if corrosion and/or deposits are noticed within the valve body, testing must be performed more often. A “try lever test” should also be performed at the end of any non-service period.

CAUTION: Hot, high pressure fluid may be discharged from body drain and vent during “try lever” test. Care must be taken to avoid any bodily contact.

CAUTION: High sound levels may be experienced during “try lever” test. 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 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 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 your model:

4. Replace the air vent nut.

5. Follow AIR VENTING INSTRUCTIONS.

6. Continue normal operating procedure of the kettle.

If cooking time is abnormally slow, it 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.

First, check that 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.

Also 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, the malfunction 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 of approximately 40 psi. If it does not, check that the Contactors are being energized and power is being made available to the heating elements. Replace defective Contactors if needed.

If a leak occurs through the valve stem, 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.

NOTICE: 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 stem and permanently damage it. This is not covered under warranty.

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: SCALD HAZARD. 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.
