This service and parts manual contains general information, installation instructions, principles of operation, trouble-shooting,
and maintenance information for Market Forge ST-12 Pressureless Steam Cooker. Also included is a part list in which each
replaceable part is identified and shown in an accompanying exploded view.
1.1 Description
The ST-12 is a pressureless steam cooker consisting of a
controlled compartment enclosed in a single cabinet. The
compartment is equipped with a separate three-piece door
with inner gasket plate isolated from the exterior surface.
The door latch design ensures positive sealing of the inner
door. Steam delivery and steam-condensing circuits are
both electrically controlled. The operating controls are
displayed on a single front-mounted panel that includes a
timer with an indicator light for the selection of constant
steam or 60-minute-long duration cooking.
A separate steam source is required for operation of the
Pressureless Cooker and is normally purchased with it,
please refer to the respective manual for guidance.
1.2 Basic Functioning
The Model ST-12 compartment is equipped with controls,
allowing selection of constant steam or 60-minute timer
operation. The cooker becomes operational when it is set
to constant steam, or the timer is set at the desired
cooking time and the compartment door is closed. The
indicator 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, completing the
circuit to the timer motor and starting the selected cooking
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.
When steam and condensate is emitted from the
compartment it is directed through a drain screen inside
the compartment into the cooker drain line. A cold water
solenoid valve connected into the compartment drain line
is automatically actuated by a thermostatic switch in the
cooking compartment drain line to condense the steam to
water prior to discharge into the drain.
