DOOR ASSEMBLY & ADJUSTMENT
STERILMATIC DOOR ASSEMBLY
The Door of the Sterilmatic has been engineered to establish a positive method of sealing the steam pressure
within the sterilizing cylinder. As steam pressure builds
up within the cylinder, the door seal will tend to become
more positive.
However, the door should be adjusted to make a good
initial seal between the door gasket and the door opening
without the added assistance of internal cylinder steam
pressure with the simple action of securing the door handle down in a locked position, the door gasket should be
sufciently compressed against the door opening, all the
way around to prevent any steam leakage from occurring.
DOOR ADJUSTMENT
The Door Adjustment is Located in the Fulcrum Casting
at the base of the door opening. This adjustment employs
the use of a screw and locknut in order to adjust the Sterilmatic Door to a tighter closed position (to prevent steam
from leaking by the door gasket as pressure builds up), it
is necessary to loosen the locknut and back off the screw
at least one-quarter of a turn and re-tighten the locknut.
Figure 1
Figure 2
THE DOOR GASKET
Keep the gasket clean. With normal closing and locking
of the door assembly, a steam-tight seal should be made
between the door gasket and the door opening. This seal
cannot be maintained if particles of foreign matter are allowed to accumulate upon either of the contacting surfaces.
If there is leakage by the door gasket before a steam
build-up within the steam chamber and leakage does not
stop when the sterilizer reaches sterilizing temperature
and pressure than regard the door assembly as improperly adjusted. A re-adjustment must then be made of the
seal adjustment door screw.
To change the door gasket, remove the entire door assembly as a unit. Discard the old gasket, replace it with
a new one (no cement is required), and reinstall the door
assembly. Make an operational check for leakage and adjust the door, if necessary.

DOOR ASSEMBLY & ADJUSTMENT
DOOR LIFT SPRING
Market Forge supplies door lift springs in sets only. This
policy has been found to be in the best interest of the
customer. Through continuous use, some of the original
qualities of the springs are lost and it becomes advantageous to make replacements to both the left and right
door lift springs in the event that one becomes damaged
or broken.
Replacement door lift springs are marked with tabs at
the factory prior to shipment to identify a right from a left
spring. These springs must be installed with the right
door lift spring on the right of the door and the left door lift
spring on the left of the door as viewed from the front of
the sterilizer.
TO REMOVE THE DOOR ASSEMBLY
The Door Assembly can be removed from the inner sterilizing chamber as a unit without the use of any special
tools or equipment. However, a systematic approach to
this is warranted as the clearances through the portal are
close, and much confusion can result if not removed in
the sequence described below:
1. First, lift off and remove the two pan supports to expose the door linkage on either side of the inner sterilizing chamber .
2. Raise the door to a fully opened position, and disengage the door spring from each of the door spring
studs. Accomplish this by counteracting the force of
the door lift spring with one hand while working the
end of the door spring off the spring stud with the free
hand. Do this on both sides of the door assembly.
3. When the end of the door springs have been completely freed from their respective door spring studs,
the door springs on either side of the door assembly
can easily be slipped off their studs.
4. Rotate the entire door assembly out through the
door opening, passing the door handle through the
opening rst, and then one end of the door spring as
shown in the illustration. The remainder of the door
assembly will then pass through the door opening
quite easily.
5. To replace the door assembly, reverse the step-bystep procedure described above.

FULCRUM AND DRAIN ASSEMBLY
THE FULCRUM & DRAIN
ASSEMBLY
The fulcrum and drain assembly is located at the lower front
of the sterilizing chamber and
furnishes a sturdy anchorage
for the door locking system of
the door handle. Also provided
in this assembly is a means for
adjustment of the door seal. The
drain port and drain valve provide a means of discharging accumulations of water from within
the sterilizing chamber.
ROLLER ASSEMBLY
(ITEMS 8 & 9)
The Roller Assembly must be
kept free-rolling at all times.
Should this assembly be allowed
to become frozen due to lack of
lubrication, undue strain will be
put on the door handle and the
fulcrum casting while the door
is being locked. Use only a dry
lubricant such as graphite; as oil
or grease will tend to attract dirt
to this area.

PRESSURE ACTUATED TEMPERATURE CONTROL
STM-E AND STM-EL
The pressure actuated temperature control, located behind the control panel assembly, governs the manufacture of steam by controlling the input of electric current to
the heating elements.
HOW IT WORKS
When the Timer is set, rear and front contactors will become energized allowing input of current to the temperature control, thus closing the contacts completing the
current to the heating elements. Steam will then be generated within the sterilizing chamber.
The steam pressure within the sterilizing chamber is
transmitted by means of a tube to the bellows of the temperature control; as the steam pressure increases, its
compression action on the bellows is set to cause the
Switch #1 on the control to cut out on rising pressure at
13.5 PSI and to cut in on falling pressure at 13 PSI (controlling the two outer banks of heating elements). Switch
#2 is set to cut out on rising pressure at 15.5 PSI and cut
in on falling pressure at approximately 15 PSI (controlling
center heater element only).
Thus, a balancing effect of steam pressure build-up and
heater element current is constantly maintained during
the sterilizing cycle. When the Timer signies the end of
the cycle, the electric current to the contactors will automatically be broken; the temperature control contacts will
be broken; and steam generation will stop.
ADJUSTING THE RANGE OF OPERATION, STM-E
NOTE: These instructions should be performed by
qualied service personnel only.
The operational range of the temperature control is factory set as follows: Outer bank of elements OFF at 13.0-
13.5 PSI; Center bank of elements OFF at 15.5- 15.0 PSI;
minor compensating adjustments can be made by turning
the adjusting screws counter-clockwise to increase pressure and clockwise to decrease pressure. Both screws
should be turned the same amount when making an adjustment.
NOTE: When resetting this control for elevations above
sea level a correction of 6/10 Ib. per thousand
feet is necessary.
1. Before making adjustments, shut all electrical current
to the sterilizer OFF to eliminate shock hazard.
Figure 5
CHECKING THE 230° SETTING, STM-EL
The Unit should be completely evacuated then temperature selector dial should be turned on 230° Fahrenheit.
Observe the current until it takes a sharp drop to approximately one-third of the full load; at this instant, there
should be a corresponding chamber pressure of 2 PSI
Observing the current further will show another sharp
drop to approximately 2 Amps; at this instant, there should
be a corresponding chamber pressure of 6.1 PSI and a
temperature reading of 228° to 232° Fahrenheit, on the
temperature gauge.
ADJUSTING THE RANGE OF OPERATION
STM-EL
The range of operation of Model STM-EL is adjusted by
simply turning the adjusting knob on the outside of the
Control Panel. A counter-clockwise turn decreases the
pressure while a clockwise turn increases the pressure.
Observe pressure and temperature gauges and adjust
knob as required.
NOTE: When resetting this control for elevations above
sea level, a correction of 6/10 Ibs. per thousand
feet is necessary.
2. Remove the Flue Cover.
3. Make sure that all exposed wires are not in a hazardous position, and then turn on electrical power.
4. Run unit through cycle, observing pressure and temperature gauges, turn adjusting screws as required.

PRESSURE ACTUATED TEMPERATURE CONTROL
STM-EX AND STM-ELX
The pressure actuated temperature control, located behind the control panel assembly, governs the manufacture of steam by controlling the input of electric current to
the heating elements.
HOW IT WORKS
When the timer is set, rear and front contactors will become energized allowing input of current to the temperature control, thus closing the contacts completing the
current to the heating elements. Steam will then be generated within the sterilizing chamber.
The steam pressure within the sterilizing chamber is
transmitted by means of a tube to the bellows of the temperature control; as the steam pressure increases, its
compression action on the bellows causes the contacts
to make or break according to the condition of the pressure at that time (rising or falling).
Switch #1 on the control is set to cut out on rising pressure at 0.95 kg/cm2 and to cut in on falling pressure at
0.91 kg/cm2 (controlling the two outer banks of heating
elements). Switch #2 is set to cut out on rising pressure
at 1.09 kg/cm2 and cut in on falling pressure at approximately 1.05 kg/cm2 (controlling center heater element
only).
Thus, a balancing effect of steam pressure build-up and
heater element current is constantly maintained during
the sterilizing cycle. When the Timer signies the end of
the cycle, the electric current to the contactors will automatically be broken.
CHECKING THE 110°C. SETTING, STM-ELX
The Unit should be completely evacuated then temperature selector dial turned to 110oC Centigrade. Observe
the current until it takes a sharp drop to approximately
one-third of the full load; at this instant, there should be a
corresponding chamber pressure of 0.14 kg/cm2.
Observing the current further will show another sharp
drop to approximately 1 Amp; at this instant, there should
be corresponding chamber pressure of 0.43 kg/cm2 and
a temperature reading of 110°C Centigrade, on the temperature gauge.
ADJUSTING THE RANGE OF OPERATION, STM-ELX
The range of operation of Model STM-ELX is adjusted by
simply turning the adjusting knob on the outside of the
Control Panel. A counter-clockwise turn decreases the
pressure while a clockwise turn increases the pressure.
Observe pressure and temperature gauges and adjust
knob as required.
NOTE: When resetting this control for elevations above
sea level, a correction of 0.13 kg/cm2 per kilometer elevation is necessary.

MISCELLANEOUS COMPONENTS
CAST-IN HEATING ELEMENTS
Located under the sterilizing cylinder is a bank of (3) Ushaped heating elements. These elements are welded in
place in a protective aluminum shield. The elements cannot be removed, and in the unlikely event that one or all
fail, the complete cylinder must be replaced.
THE LOW WATER CUT-OFF (MANUAL RESET)
Fastened to a special mounting brace behind the front
panel, the Low Water Cut-Off acts to shut off the complete
unit, should the water run dry. The Low Water Cut Off is
factory set, to shut the unit off when the cylinder temperature rises between 380
When the Sterilmatic is turned on without water or the
water has been evaporated away, the temperature of
the aluminum sterilizing cylinder will rise and by heat induction effect the Low Water Cut-Off. Its inner electrical
contacts will be forced open from heat expansion, thus
cutting off the ow of electric current to the heating elements. With the replacement of water into the cylinder
the cylinder temperature will drop and the contacts of the
Low Water Cut-Off can be again closed. The unit will only
restart after the manual button has been re-set.
o
and 440° Fahrenheit.
THE ELECTRIC CONTACTORS
The Electric Contactors are located on the top of the unit,
underneath the top ue cover. These important components receive an electrical impulse when the Timer is
turned on. When the unit reaches a pre-set pressure of
13-13.5 PSI the #1 switch will cut out causing the front
contactor to become de-energized. This, in turn, will disconnect the left and right bank of heaters and the timer
motor will start.
THE STEAM PRESSURE GAUGE
The Steam Pressure Gauge registers the pressure of
steam, which is within the sterilmatic sterilizing chamber.
To replace this unit, it is necessary to disconnect the copper tubing and to remove the two nuts holding the gauge
framework in place.
THE SAFETY VALVE
The Safety Valve is factory set to automatically open and
exhaust excess steam from within the sterilizing cylinder,
thereby assuring that operating pressures remain within
safe limits. The lever action of the safety valve must be
free to operate unrestricted at all times. If the Safety Valve
should leak continually with a pressure build-up or should
it cause an interruption on a sterilizing cycle prematurely (below 124° Centigrade on the temperature gauge),
it must be replaced. However, the temperature gauge
should rst be checked for accuracy.
THE FLUE
The Flue serves as a protective shield for the steam trap
safety valve, exhaust valve, and electrical components as
well as a mounting base for the control panel. The pressure gauge, dial thermometer, exhaust valve switch and
timer, protrude through the control panel. The Flue cover
may be removed to allow more room for servicing the
control components. The control panel face may then be
removed by unscrewing the sheet metal screws, which
mount it to the Flue.
THE EXHAUST SOLENOID VALVE
The exhaust solenoid is normally closed and only opens
at the end of the cycle when it is energized.
THE TIMER
The Sterilmatic is put into operation with the manual setting of the timer. With the setting of the timer, an electrical
current is directed to the pressure control. The current energizes the pressure control, which activates the contac-
tor coils to cause a current ow to the heating elements.
When the cylinder pressure reaches 13 to 13.5 PSI, the
timer motor and pilot light are energized. At the end of
the cycle the timer will cut off the ow of electricity to all
the components except the exhaust, the exhaust solenoid
and the timer motor. They will revert back to their original
deactivated state. The timer motor and pilot light will continue to be energized after the timed sterilizer cycle has
been completed and for two additional minutes. Only after
this will the timer and white pilot light be de-energized. If
the timer fails to operate the Sterilmatic, replace it. The
timer is replaceable only as a complete unit as factory
repairs to it would not be practical in the economical interests of the customer.

MISCELLANEOUS COMPONENTS
TO REPLACE A THERMOSTATIC ELEMENT:
1. Remove the cap of the steam trap (turn it counterclockwise).
2. Unscrew the diaphragm and seat and discard.
3. Wipe all dirt and scale from the inside of the steam
trap.
4. Place a new diaphragm and seat securely into the
steam trap and replace the cap (New Style - Part No.
98-1719).
Figure 8
THE STEAM TRAP
The Steam Trap has the very important automatic, dual
function of exhausting all air from the sterilizing compartment, and of making a suitable seal to allow a pressure
build-up of live steam during a cycle of sterilization. Also,
a slot is milled at an angle through the seat to allow a
constant bleed-off of a slight amount of steam during the
cycle to completely eliminate any air pockets in the cylinder. Failure of the trap to operate properly will result in an
uneven distribution of live steam within the compartment.
How it works
With the introduction of steam into the sterilizing com-
partment, cold air will escape. When sufcient generated
steam displaces the cold air, it will then start to exhaust
through the steam trap to heat the thermostatic element.
The expansion of the thermostatic element will make a
seal against the seat to enclose the live steam within the
sterilizing compartment and a steam pressure build-up
will occur.
