emitted from the cooker during normal operation. Next,
level the unit after it is placed in its final location. This
is accomplished by turning the bottom part of the adjust-
able feet. Using the cabinet top as a reference, obtain

3. The Steam Generator must be rinsed and drained.
Refer to the generator cleaning below for complete
instructions.
11. When the timer has counted to zero the system
needs to be rinsed which is accomplished by:
□ Turning the power OFF (the unit drains).
□ Turn the water supply on at its source.

TROUBLE-SHOOTING
GENERAL:
WARNING: WHEN YOU TURN THE POWER
ON, THERE ARE TERMINALS THAT CARRY 120
VOLTS. PROTECT THE ENDS OF THESE DIS-
CONNECTED WIRES TO PREVENT SHORTING
TO HOT LEADS.
The information in this section is intended to assist the
operator, maintenance and the service personnel in lo-
cating the source of problems which may occur with the
cooker. Before following any of the procedures given
in this section, the operator/maintenance person should
be thoroughly familiar with the operation section of this
manual.
4. Turn power ON. Using the voltmeter, check that the
power being supplied to terminals L1 and L2 is 120
volts, plus 10%, minus 15%.
If the problem cannot be readily corrected without the
use of tools, the operator/maintenance person should
contact the nearest Market Forge service agency for as-
sistance.
TESTING THE WATER FILL RELAY:
1. When the power is turned on, the LED (light emit-
ting diode) next to the water fill really should be ON.
Using the voltmeter, touching the probes to termi-
nals L2 and N.O. next to the water fill relay should
show 120 volts. Touching the probes to L2 and N.C.
should show no voltage.
WATER LEVEL CONTROL BOARD:
The Dual Function Water Level Controller is two controls
on one board. One controller maintains correct water
level in the generator, the other a low water safety cut-
off.
2. Connect the jumper to terminals “G” and “H.” After
a delay of 4-5 seconds, the relay should switch and
the LED will go OFF. Using the voltmeter, touching
the probes to terminals L2 and N.O. of the water fill
relay should show no voltage. Touching the probes
to L2 and N.C. should show 120 volts.
The following troubleshooting procedure will only deter-
mine if the Water Level Control Board is working prop-
erly, it will not determine why the board has failed.
WARNING: THIS PROCEDURE ExPOSES YOU TO A
SHOCK HAZARD AND MUST BE PERFORMED ONLY
BY qUALIFIED SERVICE TECHNICIAN.
3. Disconnect the jumper.
TESTING THE LOW WATER FILL RELAY:
Improperly connected or malfunctioning water level con-
troller may cause damage to the steam generator due
to low water, or create a scalding hazard to the operator
due to a hot water overflow condition.
1. With the power ON, the LED next to the Low Water
Relay should be OFF. Using the voltmeter, touch
probes to the L2 and N.O. terminals next to this re-
lay, there should be no voltage. Touching the probes
to terminals L2 and N.C. should show 120 volts.
TOOLS REQUIRED: A digital or analog volt meter ca-
pable of reading 120 volts A.C. and a jumper wire with
alligator clips.
2. Connect the jumper to terminals “G” and LLCO”.
The LED next to the Low Water Relay should turn
ON immediately.
3. Touch the voltmeter probes to terminal L2 and N.O.
next to the low water relay, there should be 120
volts. Touch the probes to terminals L2 and N.C.,
there should be no voltage.
Procedure:
1. Turn off all power to the unit.
2. Remove control panel or right side access panel-
Refer to Figure 6-1 for relay locations and terminal
identification.
4. Remove the jumper and turn OFF the power. Re-
connect the disconnected wires; wire to terminal
“G”, wire to terminal “LLCO”, and wire to terminal
“N.O.” of the water fill relay.
3. Remove the wires from the terminal connectors “G,
H, and LLCO.”

MAINTENANCE
GENERAL:
7. Replace the drain screen inside the cavity.
This section contains both preventive and corrective
maintenance information. Preventive maintenance may
be performed by maintenance personnel at the establish-
ment in which the cooker is installed. It is recommended
that user personnel never attempt to make repairs or
replacements to the equipment. Assistance in service
methods or a current directory of authorized agencies
may be obtained from Market Forge Industries.
8. Replace baffle, and pan supports into cooking cavity
by hanging them on their mounting brackets.
9. Leave door slightly ajar.
PREVENTIVE MAINTENANCE:
A good preventive maintenance program begins with
the daily cleaning procedure described above. Addition-
al preventive maintenance operations are presented in
this section. In establishments which employ full-time
maintenance personnel, the tasks described can be as-
signed to them. For other installations, tasks requiring
mechanical or electrical experience must be performed
by an authorized service agency.
DAILY CLEANING:
After each period of daily operation (more frequently as
required to maintain cleanliness) the cooker should be
thoroughly cleaned by completing the following steps:
1. Remove the baffle, and left and right side pan sup-
port racks by lifting them up off their mounting brack-
ets.
CAUTION: Under no circumstances should hardware
(or parts) be replaced with a different size or type other
than as specified in the parts list. The hardware used in
the cooker has been selected or designed specifically
for its application and the use of other hardware may
damage the equipment, present a safety hazard and will
void any warranty.
2. Remove the drain screen by lifting it off its mounting
studs.
3. Wash cooking compartment interior using detergent
and water. Rinse and dry thoroughly.
4. Remove the drip/spill trough.
The following sections set forth minimum preventive
maintenance procedures which must be completed peri-
odically to assure continued trouble-free operation.
5. Wash all removed pieces with a mild detergent, us-
ing a brush, and rinse. These pieces can also be
sent through a commercial automatic dish washing
machine. Set these pieces aside for reassembly.

ELECTRICAL COMPONENTS.
CLEANING INSTRUCTIONS:
The cleaning sequence is as follows:
• The red “CLEAN” light illuminates when scale builds- Procedure:

1. Remove the 6 screws that fasten the control panel
assembly onto the front of the unit.
• When the unit is to be used the unit must be cleaned,
as follows.
2. Gently move the control panel assembly out away
from the unit.
1. Turn the power switch to the off position
2. Turn off the water supply from its source
3. Turn power switch on
NOTE: A ground strap acting as a restrain prevents the
control panel from putting unnecessary strain on wires
and connections.
4. Red light is “on” and the generator will not fill with
water.
DOOR ADJUSTMENT:
The cooking compartment door alignment, door handle
tension and latch tension are pre-adjusted at the factory
during assembly. During normal usage, these should
not need any attention. Note that when the cooking
compartment doors are reversed, as described in the
service connections section on page 2 of this manual,
the doors will need to be aligned and the door latch ten-
sion will need to be adjusted (the door handle will not
need adjustment when the door is reversed).
5. Locate the reset switch on the control panel depress
it, and the red light should turn off.
6. Using a kitchen funnel, pour Market Forge’s TOTAL
CONCEPT de-liming solution (P/n 20-0318) into the
generator (2 quarts).
7. Add 5 quarts of water to fill the generator to 3/4. The
heater relay will click on.
CAUTION: READ DIRECTIONS AND INFORMA-
TION ON TOTAL CONCEPT DE-LIMING SOLU-
TION CONTAINER BEFORE USING.
DOOR ALIGNMENT:
The cooking compartment doors are pre-aligned at the
factory during assembly, and should not need adjusting
unless they are reversed. Should the doors need realign-
ment, the procedure is as follows:

lowered, and/or rotated into position by bumping it
with the palm of your hand or by using a small rub-
ber mallet.
After rinse water is drained, turn the power on, wait for
the steam ready light, and you are ready to cook. If the
clean light comes back on the cleaning procedure must
be followed again.
6. First, check the alignment at the front of the door by
making sure that the striker in the door is centered
with the latch mechanism on the front of the unit.
