Introduction
DESCRIPTION
The ST-24 is a pressureless steam cooker consisting 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 displayed 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 is required for operation of the
Pressureless Cooker and is normally purchased with it;
please refer to the respective manual for guidance.
BASIC FUNCTIONING
The Model ST-24 may be operated with only one compartment in use; or both may be used simultaneously. 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 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 ow into the compartment.
When steam owing 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.
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
cooking compartment drain to condense the steam to water prior to discharge into the drain.

WATER SUPPLY
Good quality water feed is the responsibility of the owner. Water quality
must be within the following general guidelines.
TDS: 40-125 ppm Hardness: 35-100 ppm Chlorine: <0.2 ppm
Silica: <13 ppm Chlorides: <25 ppm
Chloramine: <0.2 ppm pH: 7.0 - 8.5
The best defense against poor water quality is a water treatment system
designed to meet your water quality conditions.
