2.0 INSTALLATION INSTRUCTIONS 1. Select a location to provide drainage directly below the tangent Draw-off Valve. 2. Mark hole locations through flanged adjustable feet on KLS-DS models and through pedestal base on KPS-DS models. Remove kettle. 3. On hole locations marked, drill holes and insert expansion shields to accommodate 5/16" size lag bolts. 4. Reposition kettle. On KLS-DS models level kettle by making necessary adjustment on flanged foot. 5.
3.0 INTRODUCTION DESCRIPTION All Crown direct connected steam jacketed kettles pertaining to this manual are direct steam operated pressure vessels of a double-wall stainless steel construction forming a steam chamber (jacket) enveloping the lower two thirds of the kettle bowl surface. All kettles are stationary, floor mounted in fixed positions either on legs with adjustable flanged feet (KLS-DS models) or pedestal (KPS-DS models).
4.0 OPERATING INSTRUCTIONS CAUTION: THE APPLIANCE AND ITS PARTS ARE HOT. USE CARE WHEN OPERATING, CLEANING OR SERVICING THE APPLIANCE. OPERATING PROCEDURE 1. Ensure that draw-off valve is closed. 2. Fill kettle with product to desired level. 3. Slowly turn the steam control valve ON to full open position (counter clockwise). 4. The water or food should boil 3 - 4 minutes per gallon. If it does not then incoming pressure should be checked to determine that it is adequate to operate the kettle efficiently.
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.
3. Leave the draw-off valve open when the kettle is not in use. DAIRY DRAW-OFF VALVE CLEANING 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.
STAINLESS STEEL 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. To remove grease and food splatters or condensed vapours that have baked on the equipment, apply cleanser to a damp cloth or sponge and rub cleanser on the metal in the direction of the polishing lines.
6.0 TROUBLESHOOTING MAINTENANCE PREVENTIVE MAINTENANCE No preventive maintenance is required other than adhering to the Cleaning Procedure instructions. DRAW-OFF VALVE LEAKS If a leak occurs through the valve stem, replace the “O” ring. If the leak can be attributed to faulty sealing occurring between the stem disc and valve seat, then this problem may be corrected by cleaning off the dried-on food residue with extremely fine emery cloth.
TROUBLESHOOTING MAINTENANCE (continued) VENTING It is recommended that the “optional” steam trap assembly be installed. This should be plumbed to the exit end of the kettle. The thermostatic trap is a mechanical device that closes on high temperature and opens when the temperature drops, allowing the water which formed from condensate to exhaust but retain the steam under pressure.
