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-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: fect the life to the aluminum cylinder. The pH range that would be recommended is between 7.0-8.5.
SECTION 3 OPERATING INSTRUCTIONS do not recommend the sterilization of large packs, such as linens. Be sure condensate baffles are in position in the chamber. trays having mesh or perforated bottoms. Place trays flat on shelves. • COMBINING FABRICS & HARD GOODS: 9. Remove load and check water level for next operation. • PLASTIC UTENSILS: DO NOT stack or nest STERILIZATION GUIDE: • PACKS (Linens, gloves, etc.
SECTION 4 MAINTENANCE DAILY CLEANING PROCEDURE (AT THE END OF EACH DAY): 1. Remove bottom splash baffle. NOTE: IMPORTANT! STERILIZING CHAMBER MUST BE CLEANED AND DRAINED DAILY USING THE FOLLOWING PROCEDURE. WASH WETTED PORTION OF THE CYLINDER THOROUGHLY BY ADDING A MILD DETERGENT TO WATER IN CYLINDER. 2. If a soft cloth or brush is used with the detergent and does not completely remove the surface film, a nylon soap pad should be used.
SECTION 5 FIELD SERVICE INSTRUCTIONS & 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 FIELD SERVICE INSTRUCTIONS & ASSEMBLY Door Assembly ITEM PART NO.
SECTION 5 FIELD SERVICE INSTRUCTIONS & 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 FIELD SERVICE INSTRUCTIONS & ASSEMBLY DOMESTIC temperature gauges, turn adjusting screws as required. THE 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.
SECTION 5 FIELD SERVICE INSTRUCTIONS & ASSEMBLY 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. sea level, a correction of 6/10 Ibs. per thousand feet is necessary. CAST-IN HEATING ELEMENTS: Located under the sterilizing cylinder is a bank of (3) Ushaped heating elements.
SECTION 5 FIELD SERVICE INSTRUCTIONS & ASSEMBLY 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.

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. TROUBLE POSSIBLE CAUSE Not installed correctly. Blown fuse. Contactor burned out. Wiring is defective. CORRECTION Sterilizer fails to operate at all (no pressure build up). 1. 2. 3.
