INTRODUCTION

General

The procedures in this manual apply to all models unless otherwise specified. The pictures and illustrations are of a model K40ELT kettle unless otherwise noted. All information and specifications contained in this manual are based on the latest product information available at the time of printing.

Stationary and Tilting Kettles

The electric stationary and tilting kettles are self contained two thirds jacketed kettles. The lower two thirds of the kettle bowl is a double wall stainless steel construction that provides a reservoir for a solution of heat transfer fluid and distilled water for improved heating of the kettle contents. The kettles are used to prepare a variety of liquid or semi-liquid food products such as soups, stews and sauces.

The 208/240V electric kettles are wired from the factory for a 208V 3-phase supply. If connecting to 240V 3-phase supply, the primary voltage tap on the transformer must be changed to this voltage. For connecting to a single phase supply, the wiring between terminal block and contactors must be changed as shown in the WIRING DIAGRAMS.
