INSTALLATION AND SERVICE CONNECTIONS 2.0 INSTALLATION INSTRUCTIONS UNPACKING 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. Before installing, verify that the electrical service agrees with the specifications on the rating plate located on the right side of the tilt console. If the supply and equipment requirements do not agree, contact your dealer.
ELECTRICAL CONNECTIONS A Control Box with power supply equivalent to electrical rating of the kettle should be located conveniently nearby. 1. Remove the wiring compartment cover and make electrical connections per wiring diagram located inside the control housing cover panel. A waterproof electrical connection from power supply to rear of control housing must be provided. 2. Kettle must be grounded in accordance with requirements of the National Electrical Code or applicable local codes. 3.
3.0 INTRODUCTION DESCRIPTION All electrically powered kettles described and referred to in this manual are pressure vessels of a double-wall construction forming a sealed jacket (chamber) enveloping the lower two thirds of the kettle bowl surface. The kettle bowl is the container for the food product which ideally should be a liquid or semi-liquid consistency to achieve complete contact with the bowl surface.
FUNCTIONING MODE All electrically powered self steam generating kettles consist of a jacket containing a permanent solution of water and antifreeze sufficient to completely immerse and protect replaceable electric heating elements. To minimize tampering, the Safety Valve is plumbed toward the rear of the kettle jacket.
4.0 OPERATION INSTRUCTIONS 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 kettle is on. 2. Check pressure gauge for correct cold kettle reading. Reading should be in the green area of the gauge indicating 25 - 30 In. Hg (630 - 730 mm Hg) of vacuum. If reading is not low enough, follow VENTING procedure in Troubleshooting section prior to using kettle. 3. Place power switch to ON position. 4.
7. When cooking is finished set thermostat knob and power switch to OFF position. 8. Pour finished product from kettle using tilt handle. Be careful to avoid splashing. 9. Add water to kettle for cleaning purposes. 10. Wash kettle thoroughly. See CLEANING procedure, next section.
5.0 CLEANING INSTRUCTIONS CAUTION: Do not use cleaning agents that are corrosive. WARNING: Disconnect the power supply to the appliance before cleaning or servicing. WARNING: Never spray water into electric controls or components! CAUTION: The equipment and its parts are hot. Use care when operating, cleaning and servicing. Your kettle should be cleaned immediately after each use or when cooking a different product. Before cleaning, check that the kettle has cooled enough to touch it. 1.
DRAW-OFF VALVE CLEANING 1. If equipped with a tangent draw-off valve, turn the large hex nut on the draw-off valve counter clockwise 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.
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 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.
6.0 GENERAL MAINTENANCE No general maintenance is required other than adhering to the Cleaning Procedure instructions. WARNING: Contact the factory, the factory representative or local service company to perform maintenance and repairs. SAFETY VALVE MAINTENANCE AND TESTING CAUTION! Under normal operating conditions a “try lever test” should be performed every two months.
7.0 TROUBLESHOOTING 7.1 LOW WATER LEVEL Proper water level must be maintained within the jacket for the kettle to operate. Depletion of water may occur from excessive opening of or leakage through the safety relief valve. If water is below required operating level, either initially at start-up or during use, the kettle will automatically shut off and the LOW WATER signal light will come on.
7.0 TROUBLESHOOTING (Continued) 7.2 EXTREMELY SLOW COOKING TIME 1. If the cooking time is abnormally slow, then the difficulty may be due to air being present in the kettle jacket. To remove air, follow AIR VENTING INSTRUCTIONS. 2. If the kettle will not reach and maintain 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 jacket including the heating element gasket. Tighten or replace if necessary. 3.
7.5 AIR VENTING INSTRUCTIONS Check vacuum/pressure gauge when the kettle is cold. Gauge should be in the green vacuum zone, indicating a vacuum between 25-30 In. Hg (630 - 730 mm Hg). If not, air must be vented (removed) for proper heating. Use the following procedures to vent air. 1. Place power switch ON with kettle empty. 2. Set temperature control thermostat to ‘10'. Heat kettle until indicator light goes off. 3. Using a 7/16" wrench, open bleed vent one full turn for 10 seconds and then close.
