INTRODUCTION

This service and parts manual contains general infor- mation, installation operation, principles of operation, trouble-shooting, and maintenance information for the Market Forge 3500 Pressureless Steam Cookers. Also included is a parts list in which each replaceable part is identified and shown in an accompanying ex- ploded view.

The 3500 is a pressureless steam cooker consist- ing of two independently controlled compartments enclosed in a single cabinet. Each compartment is equipped with a separate three-piece door with inner gasket plate isolated from the exterior surface.

Door latches operate by action for positive sealing of inner door. Steam and steam-condensing circuits are electrically controlled. Operating controls are dis- played on a single front-mounted panel and include separate timers with indicator lights for selection of constant steam or 60 minute long duration cooking.

A separate steam source required for operation of the Pressureless Cooker is normally purchased with it, please refer to the respective manual for guidance.

BASIC FUNCTIONING:

The Model 3500 may be operated with only one compartment in use; or both may be used simultane- ously. Each compartment is equipped with identical controls, allowing selection of constant steam or 60 minute timer operation.

The cooker becomes operational when it is set to con- stant steam, or the timer is set at the desired cooking time and the compartment door is closed. The indi- cator light comes on and the steam solenoid valve opens, allowing steam to flow into the compartment.

When steam flowing inside the compartment has raised the interior temperature to 195°F, the contacts of a thermostatic switch automatically close, complet- ing the circuit to the timer motor and starting the cook- ing time period.

At the end of the set interval, timer contacts switch to shut off the cooking operation and sound a signal buzzer. The buzzer is silenced by returning the timer dial to the OFF position. In the constant steam mode, operation will be continuous.

Steam emitted from the compartment along with liquid cooking drainage is directed through a drain screen inside the compartment into the cooker drain line.

A cold water solenoid valve connected into the cooker drain line is automatically actuated by a thermostatic switch in the boiler drain to condense the steam to water prior to discharge into the boiler drain.
