1. Introduction
1.1 Description
The Eco Tech® represents the latest in counter top steam
technology, designed to apply the benefits of steam cooking
to today’s health-conscious menus. Ideal for batch cooking,
à-la-carte, and rethermalization of individual entrées, the Eco
Tech™ puts the power of steam on your counter top. The Eco
Tech™ is a pressureless steam cooker consisting of:
• 3, 5, or 6-pan cavity
• Electric pressureless generator (6, 9, or 12-kW inputs)
• Mechanical controls
• Low water indicator
• Hold feature
These features and functions will be discussed in greater detail in Section 3.
A steam-on-demand steam generator system gives quick
start-ups and efficient steam transfer to the cooking compartment, without the use of expensive vacuum pumps. In tests
for energy efficiency and cooking times performed in accordance with ASTM standards, the Eco Tech® yielded impressive results over other similar counter top steamers.
For continuous steam, set the selector timer knob to the “constant steam” position (the green area of the selector/timer
switch). The cooker will continue to steam until the switch is
moved to the “Hold/Idle” position.
If you desire a timed steam cooking cycle, just set the timer
knob to the cook time (up to 60 minutes).
In the timed steam mode, the cooker will create steam for the
duration of time you have set. Once the timer reaches the end
of its cycle (0 minutes), the buzzer will sound. The buzzer is
silenced by returning the timer knob to the “Hold/Idle” position, which ceases the steaming function. The generator will
continue to idle at 170°F.
Each unit is equipped with a standard steam-and-hold feature. At the completion of the cooking cycle, place the timer
knob to the “Hold/Idle” position.
The hold feature is controlled by a separate thermostat with
an additional temperature gauge mounted just below the control panel. The unit will now act as a holding cabinet until
you call for steam again. During this time, the generator will
continue to idle at 170°F.
With the “hold” feature, your Eco Tech® will keep cooked
foods at 160°F until you are ready to serve, giving you more
time between cooking and serving—it’s a Market Forge exclusive.
As your operation grows, so does your Eco Tech®. By
stacking multiple Eco Tech® models, you can accommodate
up to 10 pans, creating a complete high-output steam cooking system.
1.2 Basic Functioning
To begin operation, the power switch is pressed into the ON
position, illuminating the power light. Pour about 2 1/2 gallons water into the steam generator, located at bottom of cavity. DO NOT exceed the “MAXIMUM WATER LINE”.
Turn the timer to approximately 15 minutes. This will energize the heating elements. At the end of 15 minutes the buzzer
will go off, indicating that the unit is now ready to cook.
A steaming mode is selected with the timer/selector switch.
The steam generator is drained from the bottom of the unit.
You need at least a 4” deep steam pan underneath the unit.

3. Initial Systems Inspection
3.1 General
This section contains information for you to test and familiarize yourself with the operation of the Eco Tech™.
After the cooker is completely assembled, all packaging materials removed, and all service connections are made, all systems must be given a thorough checkout before being put
into operation. We begin by making sure that the drain valve
is closed and the empty drain pan is in its proper position.
Pour about 2 1/2 gallons of water into the bottom of the cooking cavity or up to the “MAXIMUM WATER LINE”.
Mount both racks and the Ala - Carte - Shelf in place.
Confirm that all service connections are correct. Close the
cooking compartment door, and turn the timer knob to
15 minutes.
3.2 Warm-up
Push the power switch to the “ON” position. The heaters will
energize. After 15 minutes the buzzer will go off, indicating
that the steamer is ready to cook. The temperature gauge will
indicate a 212°F temperature. At this time you may choose
either to load food to cook or turn the timer knob to “hold /
idle” mode prior to actual cooking. In the hold / idle mode,
the temperature gauge will show a temperature of around
170°F.
3.3 Timed Steam Mode
Set the selector/timer knob to 10 minutes and close the door.
The temperature gauge will slowly register increasing temperatures up to 212°F.
When the timer reaches 0 minutes, the buzzer will sound.
The buzzer is silenced by returning the selector/timer knob
to the “hold / idle” position.
3.5 Hold / Idle Mode
You enter this mode by placing the selector/timer knob to the
“Hold / Idle” position. This mode only works if the steaming
cycle has been completed and the door has been left closed.
The cooking cavity will hold product between 150°F - 190°F
3.6 High / Low Power Switch

Your Eco-Tech
system. This feature allows smaller portions to be cooked
with less power. If your menu demands are reduced, the
Eco - Tech allows you to save energy. This is a Market Forge
exclusive!
comes with a unique “High / Low Power”
3.7 Low Water Signal
During cooking, the water in the steam generator will keep
evaporating. When the generator is nearly empty, the heaters, for safety reasons, will be turned off and a beeper will
sound, indicating an abrupt end to the cooking mode and a
need to add water until the beeper turns off.
3.8 Shut Down
No special procedure is necessary for shutting the unit down.
Simply press the power switch into the “OFF” position, and
open the drain valve at the bottom. The indicator lights on
the control panel will go out, and the generator will drain.
Then empty the drain pan.
Caution: When the unit is not in use, leave the cooking
compartment door slightly ajar to prolong the life of the
door gasket.
3.4 Constant Steam Mode
The constant steam mode overrides all other cooking modes.
This mode is entered by turning the selector/timer knob to
the “constant steam” position on the dial (green area). With
the knob set for constant steam, and the door closed, the temperature gauge should indicate a temperature of 212°F.
