SECTION 1 INSTALLATION INSTRUCTIONS
INSTRUCTIONS FOR INSTALLING PAN SUPPORTS AND BAFFLES
Locate the mounting studs on the inside of the chamber. There are two rack mounting studs on each side
(see Fig. 1).
Taking one pan support and positioning rack so that the pan stop is facing the rear of the unit and the wires
are facing toward the center of the unit. The pan stop is a piece of sheet metal welded to the rack with a 65° bend.
Begin to hang the pan support by placing the rear key-way slot onto the rear mounting stud and slide the rack
until the slot sits on the mounting stud. When this is done correctly the front mounting stud will be in position
to place the front key-way slot. Slide the rack down into its correct position (see Fig 2).
After installing one pan support rack correctly, you can install the upper bafe. Position the bafe so that the
45° bend is facing up towards the front of the unit (see Fig. 3). Slide the mounting tab onto the at bend on
the pan stop bracket. The bafe should now stay in place by itself, but in a tilted state (see Fig. 4).
Position the second pan support rack into the cavity and slide the other mounting tab onto the rack at bend
while the pan support rack is not on the mounting studs. Hang the pan support by placing the rear key-way
slot onto the rear mounting stud and slide the rack until the slot sits on the mounting stud. When this is done
correctly the front mounting stud will be in position to place the front key-way slot. Slide the rack down into
its correct position.
Place the Perforated Water Bafe so that it sits on the bottom of the inside of the sterilizer chamber (see Fig. 5).
CAUTION: Do not cover the holes in the Perforated Water Bafe by using it as a shelf. This will result in a
disrupted ow of steam.
THE ELECTRIC SUPPLY CONNECTIONS FOR STM-ED: Connect to proper electrical supply as indicated on
nameplate on top of unit. The power supply cord is brought in from the rear of the unit, through the conduit and
the connection is made at the terminal box located at the front of the unit.
THE ELECTRIC SUPPLY CONNECTIONS FOR STM-EDX: Connect to proper electrical supply as indicated on
nameplate on top of unit. Connection is made from the rear of the unit, through the conduit to the terminal box
located at the front of the unit. All control circuits are 220 volts.
In order to accomplish this, a current-carrying grounded neutral must be provided.
Thus, a three phase system must be 4-wires. Most electrical codes require, and we recommend, that a separate
switch be located within sight of the sterilizer.

SECTION 2 WATER CONDITIONS
Market Forge from time to time is asked the question about using distilled or deionized water for use with our
Sterilizer models STM-ED and STM-EDX. We are always asked why these water choices are not allowed for use
with our units and what would be recommended. To address this situation, we have complied the following as a
means of satisfying these questions:
We have found that the use of distilled or deionized water will aggressively attack the pure coat of Aluminum
Alclad, which protects the bottom surface from oxidizing and then eventually pitting (reference: Operating
and Maintenance Instructions).
In addition pitting can also be caused by several other external environmental factors. Few examples are as
follows. These conditions have been highlighted in our documentation.
Grains of hardness in the water supply should be as follows (.25 to 2).
A pH imbalance in the water supply can greatly affect the life to the aluminum cylinder. The pH range that
would be recommended is between 7.0-8.5.
The lack of a positive electrical ground can cause an electrolytic reaction that will accelerate pitting.
Another contribution to accelerate pitting is the type of cleaning solutions used or the abrasive scrubbing
pads. If a low pH is present with the detergents being used or an abrasive pad, the protective Alclad coating
will be removed during the cleaning process.
Spillage of media being sterilized can also contribute to the accelerated pitting if it is corrosive.
CHLORINE LEVEL ≤ 1 PPM.
IMPORTANT NOTE:
Market Forge will not be responsible for damage resulting from the use of hard or corrosive water, from
failure to drain the unit daily, or from inadequate cleaning procedures.

SECTION 3 OPERATING INSTRUCTIONS
GENERAL OPERATING INSTRUCTIONS:
IMPORTANT: Make sure the drain valve is closed.
Fill bottom of the sterilizer chamber with approxi-
mately six quarts of water or just below ledge at
bottom of door opening. (If water supply is known
to be hard or corrosive, a source of treated water
should be used.) DO NOT USE DISTILLED OR
DEIONIZED WATER. (See section 2)
LOAD STERILIZER: Use proper sterilizer load-
ing procedures when placing materials in sterilizer
chamber. All solid containers or instruments must
be placed so that water or air will not be trapped
in them.
CLOSE DOOR: Grasp handle, and holding it
in vertical position, pull door down until bottom of
door rests in the bottom of door opening. Then
rotate handle forward, engaging the lower curved
portion under the horizontal rod in the casting at
the bottom of the door opening. Push handle all the
way down and back until door is locked securely in
position.
DETERMINE CORRECT STERILIZATION
TIMES: (Referring to page 11 for minimum steril-
ization times table.) NOTE: In no case should the
timer be set to less than 15 minutes. Sterilization
will not be accomplished in less than 15 minutes
exposure time.
When the sterilizer chamber reaches the selected
temperature, the timed Heating/Sterilization cycle
will begin. When the Heating/Sterilization cycle
is completed, the electric supply to the heating
elements will be opened (shut off) automatically.
When the chamber pressure reaches 0 (zero) the
door may be opened.
NOTE: Before opening the chamber door be
sure to have the Control Panel Flip Cover in the
‘DOWN’ position. This protects the LCD screen
from coming into contact with too much steam.
At this point you may release the handle and let
go to avoid possible contact with the remaining
escaping steam. When opening the door allow a
few seconds for steam to escape from the cham-
ber before opening completely.
NOTE: For more detailed Operating Instructions
please refer to Section 3 titled ‘DETAILED OP-
ERATING INSTRUCTIONS’
To assist in drying racks, release door handle af-
ter pressure has been attained at start of cycle.
Pressure in chamber will keep door closed. The
use of a wire basket will provide better drying for
dressings. At end of sterilizing cycle, release door
handle and open slightly. Do not lift door to open

position. This will allow steam and moisture to es-
cape. Allow door to remain in this position for 15
to 20 minutes before removing load. Small packs
can be dried successfully with this procedure. We
do not recommend the sterilization of large packs,
such as linens. Be sure condensate bafes are in
position in the chamber.
Remove load and check water level for next opera-
tion.
STERILIZATION GUIDE:
PACKS(Linens, gloves,etc.): Use wire basket
to facilitate drying. Be sure condensate bafes are
in place. Place packs on edge and arrange load in
chamber, so that only minimal resistant to passage
of steam through the load will exist.
NOTE: Place gloves in upper two-thirds of chamber.
JARS, CANISTERS (etc.): Place containers on
side to allow for displacement of air and complete
contact of steam to surfaces. Drying is also facili-
tated.
PETRI DISHES, PIPETTES, DESICCATORS
(etc.): Should be inverted.
UTENSILS, TREATMENT TRAYS: Placed on
edges to facilitate drying.
INSTRUMENT SETS: Place instruments set in
trays having mesh or perforated bottoms. Place
trays at on shelves.
COMBINING FABRICS & HARD GOODS:
Place hard goods on lowest shelves.
PLASTIC UTENSILS: DO NOT stack or nest
plastic items.
LIQUIDS: Sterilize liquids separately from other
supplies or materials. Set vent to slow.
SMALL ITEMS: Sterilize small items in baskets,
or trays.
NOTE: IF THE EQUIPMENT IS USED IN A MAN-
NER NOT SPECIFIED BY THE MANUFACTURER,
THE PROTECTION PROVIDED BY THE EQUIP-
MENT MAY BE IMPAIRED.

SECTION 3 OPERATING INSTRUCTIONS
B. Controller Overview
The Digital Controller is made up of the Operational Keys, Digital LCD Display and the Data Logger/Printer. The
operator can set the controller to display in either degrees Fahrenheit (°F) with pressure in PSI or in degrees
Celcius (°C ) with pressure in kPa.
During operation the Digital LCD Display will show the actual temperature within the sterilizer chamber, the time
remaining for the sterilizer cycle and the vessel pressure in digital form and bar form. It will also display the cur-
rent cycle state, Heating up, Timing (sterilizing) or Venting.
The three operating parameters that can be set by the operator are sterilizing Temperature, sterilizing Time
and Venting mode.
The sterilizing temperature can be set in a range from 225°F (107°C) to 250°F (121°C).
The sterilizing Time can be set in Minutes and Seconds (if desired).
The Venting mode can be set to FAST (approximately 3 minutes) or SLOW (approximately 11 minutes).
To initiate a sterilizing cycle you need to set three parameters, Temp, Time and Venting. Or you can set com-
monly used values for these parameters into three ‘Preset’ keys. Each Preset key can store a value for all three
parameters. The parameter values stored in the Preset keys can easily be selected before running a sterilization
cycle. This avoids you having to set all three parameters every time you run the unit.
Each sterilization cycle records the temperature, time and pressure at one minute intervals during the heat-up
cycle, the sterilization cycle and the venting cycle. These cycles are described in more detail below. The re-
corded data can be printed out after each complete run or printed out later, on an as-needed basis.
C. Setup
Make sure unit is connected to its electrical source. Make sure unit has recommended amount of water in its
chamber. Make sure unit drain is closed. If a ventilation hood is required, make sure unit is placed accordingly
under the hood.
Be sure that the unit’s door is closed and locked before operating!
Once the unit has power, push the black Control Panel Power switch to On ( I ). This will bring power to the
control panel and illuminate the Digital LCD Display screen.
You are now ready to use the unit.
D. Manual Programming
The rst step is to decide what form of temperature and pressure measurement you want to use, Fahrenheit and
PSI or Celsius and kPa. This can be changed at any point during operation.
Setting units (°F & PSI) or (°C & kPa);
Press and hold the UP key and the DOWN key while simultaneously pressing and releasing the TEMP
key will toggle between (°F/PSI) and (°C/kPa).
Setting Temperature
While the unit is powered up but not in use, considered the ‘Idle State’, the temperature being displayed
is the current temperature within the sterilizer chamber.
Pressing and releasing the TEMP key will display the current set-point temperature for three seconds.
To set the target sterilization temperature set-point;

SECTION 3 OPERATING INSTRUCTIONS
Press and hold the TEMP key until the display goes blank and shows only the temperature. Now
press the appropriate UP or DOWN key to get to desired set-point.
When the full display returns the target set-point has been set.
Setting Time
While in the ‘Idle State’ the Time being displayed is the current time set-point.
To set the target sterilization time set-point;
Press and hold the TIME key until the display goes blank except for the minutes. Now press the
appropriate UP or DOWN key to reach the desired sterilization set-time minutes.
After three seconds the minutes will blank and the seconds set-point will be displayed. If you
need to set the desired seconds, again, use the appropriate UP or DOWN keys.
If seconds are not required than either don’t touch any key and after three seconds the full dis-
play will come back and the TIME is now set or immediately press the TIME key again and that
will also set the time.
Setting VENT mode
While in the ‘Idle State’ the VENT mode will be displayed as either FAST or SLOW, whichever is active.
To set the desired VENT mode (SLOW or FAST);
At any point during any cycle the VENT mode can be toggled simply by pressing and releasing
the VENT key.
Starting the unit
Once you have set your desired TEMP, TIME and VENT type you can now proceed in starting the unit.
To start unit;
Press the START/CANCEL key
Stopping the unit
Once the unit is started it will run through all 3 cycles automatically (cycles are described below) and fin-
ish in the DONE state (also described below).
If at any time throughout the cycle you have to stop or cancel the cycle just press and hold (for 3 seconds)
the START/CANCEL key.
After stopping the unit in this manner the unit will still have to go through the VENT cycle to release the
pressure within the chamber before you can open the unit door.
Description of cycles;
HEATING cycle – Once the START/CANCEL key is pressed the unit will flash the HEATING icon while
the sterilizer is heating up to the sterilization temperature set-point. While it is heating the set-point TIME
is displayed and will not change.
TIMING (sterilizing) cycle – When the unit reaches its set-point temperature the unit will enter the steril-
ization or TIMING cycle. At this point the unit will display and count down the sterilization time.
VENTING cycle – When the timing (sterilization) cycle time reaches zero the set VENTING cycle begins.
The FAST VENT is programmed to vent for 3 minutes through the solenoid valve. The SLOW VENT is
programmed to vent for 11 minutes through a bleeder orifice.
DONE state – At the completion of the VENTING cycle the unit will display DONE and a beeper will
sound. The beeper sequence will be ON for 1 second and OFF for 9 seconds. This sequence will repeat
until any key on the control panel is pressed or 3 minutes have passed.
Once in the DONE state it is safe to open the chamber door. Before opening the chamber door be sure
to have the Control Panel Flip Cover in the ‘Down’ position. This protects the LCD screen from coming
into contact with too much escaping steam from the chamber. When the door is left in the closed position
you may notice a rise in the temperature and pressure on the LCD screen. You should open the chamber

door to allow the chamber to cool.
NOTE: There is never any harm in releasing the chamber door latch. If there is pressure inside the cham-
ber the door cannot open due to its design which does not allow the door to open under pressure.
E. Preset Keys
There are three PRESET keys numbered 1, 2 & 3. In each key you can save set-point values for the Tempera-
ture, Time and Vent mode. For example, if you commonly need to sterilize a media that requires specic set-
point values, you can save these specic values into a PRESET key. This way you don’t need to keep setting
the Temp, Time and Venting info before each running of a sterilization cycle.
Programming PRESET Keys
To save values into a PRESET key;
Press and hold the desired PRESET key (1, 2 or 3). The display
shows the values currently stored in that preset key. When the
“PRESET” icon and the preset “number” icon in the display start to
flash, the values are now ready to re-program. At this point you can
change any or all of the parameters, Temp, Time, Vent as described
previously.
Every three seconds without an UP or DOWN key press the display
will proceed from TEMP, MINUTES, then to SECONDS waiting for
new preset set-points then exits the program preset state.
During this programming state you can advance from the Temp
menu to the Time menu simply by pressing the TIME key.
Likewise, while in the Time menu you can advance from Time-min-
utes to Time-seconds simply by pressing the TIME key.
In addition, while in the Time menu you can go back to the Temp
menu by pressing the TEMP key.
At any point during this programming state you can press the appro-
priate PRESET number key and that will store the new values and
exit the programming state.
Using PRESET Keys
While the unit is in the ‘Idle State’ simply press the appropriate PRESET key
(1, 2 or 3) to use the values previously stored into that PRESET key. At this
point you just need to press the START/CANCEL key.
F. Printing/Data Logger
This unit is set up to record the Time, Temperature and Pressure during all phases of
the full sterilization cycle. All three of these parameters are recorded at one-minute
intervals. The data logging clearly labels the printed output with headers separating
the three cycles, HEATING, STERILIZING and VENTING.
Each run is assigned a unique ID number that is printed at the top of the printout.
Each unique ID number is made up of two numbers separated by a dash (-).
(Example; #237-00053)
PRINT OUT EXAMPLE 
The rst 3 digit number is a number that never changes. It is a unique number that identies the sterilizer unit
itself. The last ve digits are incremented by one for every time the unit is run.

SECTION 3 OPERATING INSTRUCTIONS
Also included at the end of each printout is the following; Example:
The DATE, OPERATOR and COMMENTS elds can be hand written in if
required.
PRINT Key
In the LCD Display, if the word PRINT is displayed then the recorded data will be automatically printed
at the end of the full sterilization cycle. Likewise, if the word PRINT is not displayed then the recorded
data will not be printed automatically after the full sterilization cycle completes.
To toggle between PRINT enable and PRINT disable just press and release the PRINT key. This can
be performed at any time during the Heating, Timing (Sterilization) or Venting cycles.
Printing previously run cycles
The data logger will store approximately 20 full sterilization cycles. This number may vary slightly de-
pending on how long each cycle runs. For example, the data logger can store more cycles set at 30
minutes versus cycles all set at 60 minutes.
As stated before each full cycle is assigned a unique ID number. This number can be used to scroll
back through the data logger and print out the exact cycle you want to print out. There is also an option
to print out ALL the previous cycles.
To print out selected cycles;
Press and hold the PRINT key. The display will show the ID of the last run cycle. To scroll back
through the cycles just press the DOWN key. Likewise, during the scrolling, you can hit the
UP key to scroll forward through the cycles. At your selected cycle ID number just press and
release the PRINT key.
To print out all the cycles;
Press and hold the PRINT key. When the display shows the last run ID number keep hitting the
DOWN key until the word ‘ALL’ is displayed. Now press and release the PRINT key.
Printer Paper cutting
The paper will be cut automatically at the end of each single print or printing ALL.
G. Printer Paper Changing
Follow these steps to re-load the printing paper;
Push the printer door “open” button. Two doors will open, the inner door and outer door.
Remove paper roll spool from printer. Remove black plastic spindle from center of spent paper roll. DO
NOT DISCARD BLACK PLASTIC SPINDLE!
Insert black plastic spindle into new paper roll. Insert new paper roll into printer. (Note: paper exits
from top of roll)
