SECTION 1 INSTALLATION INSTRUCTIONS AUTOMATIC STERILMATIC STEAM PRESSURE STERILIZER MODELS: STM-E, STM-EL, STM-EX & STM-ELX Your Sterilmatic Sterilizer has been developed to answer the need for a compact, automatic, low-cost steam pressure sterilizer. The following instructions cover installation. Should service be required, it is readily available by contacting our authorized service agency located nearest to you.
SECTION 1 INSTALLATION INSTRUCTIONS TRAY SUPPORTS Install side tray supports. Tray supports are attached by means of key-hole clearance slots which are slipped over studs located on the sides of the Sterilmatic chamber. BAFFLE INSTALLATION To insure maximum drying of packs, a baffle is supplied with your STM-E Sterilmatic. Place perforated splash baffle in bottom of the sterilizing chamber. Install small baffle with no perforation at the rear of the upper tray support channel.

SECTION 1 INSTALLATION INSTRUCTIONS INSTRUCTIONS FOR INSTALLING PAN SUPPORTS AND BAFFLES 1. Locate the mounting studs on the inside of the chamber. There are two rack mounting studs on each side. 2. 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 65o bend. 3.
SECTION 1 INSTALLATION INSTRUCTIONS THE ELECTRIC SUPPLY CONNECTIONS FOR STM-E AND STM-EL Connect to proper electrical supply as indicated on nameplate on top of unit. Connection is located behind the terminal box cover at the lower left side of unit. Whether the supply current is 208 or 240 volt, single phase or three phase, all control circuits are 120 volts. In order to accomplish this, a current-carrying grounded neutral must be provided.

SECTION 1 INSTALLATION INSTRUCTIONS INSTALLATION FOR OPTIONAL RECORDING THERMOMETER The Optional Recording Thermometer may be surface or panel mounted as best accommodates the layout of the sterilization area. 1. Remove the top cover. Remove the pipe plug located in the T-fitting that also accommodates the safety relief valve and which is connected directly to the sterilizing chamber. 2. Insert the thermometer bulb of the temperature recorder into the pipe, from which the plug was removed. 3.
SECTION 2 WATER CONDITIONS Market Forge from time to time is asked the question about using distilled or dionized water for use with our Sterilizer models STM-E and STM-EL. 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: 1.
SECTION 3 OPERATING INSTRUCTIONS OPERATING INSTRUCTIONS: 1. IMPORTANT: Make sure the drain valve is closed. Fill bottom of the sterilizer chamber with approximately six quarts of water or just bellow 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 DIONIZED WATER. (See page 13) 2. LOAD STERILIZER: Use proper sterilizer loading procedures when placing materials in sterilizer chamber.
9. Remove load and check water level for next operation. SECTION 3 OPERATING INSTRUCTIONS STERILIZATION GUIDE PACKS (Linens, gloves, etc.) – Use wire basket to facilitate drying. Be sure condensate baffles 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 twothirds of chamber. JARS, CANISTERS (etc.
SECTION 3 OPERATING INSTRUCTIONS MINIMUM STERILIZATION TIMES TIME (Minutes) 15 20 30 45 ARTICLES - Glassware, empty, inverted. - Instruments, metal in covered or open tray, padded or unpadded. - Needles, unwrapped. - Pipettes, blood diluting, serological, volumetric, etc - Tubing glass (6mm), (10mm) inverted - Flasked solutions 75-250 mo. - Instruments, metal combined with other materials in covered and/or padded tray. - Instruments wrapped in double thickness muslin.
SECTION 5 ASSEMBLY STERILMATIC OPEN STAND Market Forge Sterilmatic Stand can be supplemented with an Optional Stand for utility use where maximum compactness is desired. The sturdy, stainless steel unit is equipped with adjustable leg extensions which allow the unit to be installed and leveled over existing contours in the floor . The open design lends itself to maximum sanitary conditions because of the ease with which periodic cleaning can be done.
SECTION 5 ASSEMBLY 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. THE DOOR GASKET Keep the gasket clean.
SECTION 5 ASSEMBLY 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.
SECTION 5 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.
SECTION 5 ASSEMBLY 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.
SECTION 5 ASSEMBLY EXPORT THE 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.
DOMESTIC SECTION 5 ASSEMBLY 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 an- other sharp drop to approximately 2 Amps; at this instant, there should be a corresponding chamber pressure of 6.
SECTION 5 ASSEMBLY 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 contactor coils to cause a current flow to the heating elements. When the cylinder pressure reaches 13 to 13.5 PSI, the timer motor and pilot light are energized.
SECTION 5 ASSEMBLY TO REPLACE A THERMOSTATIC ELEMENT 1. Remove the cap of the steam trap (turn it counter-clockwise). 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 stea trap and replace the cap (New Style - Part No. 98-1719).

SECTION 7 TROUBLE-SHOOTING STEAM TRAP TROUBLE-SHOOTING Trouble can only occur either through the premature closing of the steam trap before all the cold air has been exhausted, or by its failure to close sufficiently to enable a proper steam pressure build-up. Either case warrants a replacement of the thermostatic element.
