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 identied 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 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, 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.
