Manual Use When Damaged Component Is Known. () Replace or adjust component in accordance with Maintenance/Service Instructions (Refer to para.).. Description Of M7 Sterilizer A. General Description (See Figure -). The M7 SpeedClave Sterilizer is a self generating steam sterilizer designed to sterilize instruments and other sterilizable goods. The major components of the sterilizer consist of a chamber, condensing tank assembly, heating element, temperature regulator relay, diaphragm cup, timer assembly, timer buzzer, manual reset overheat thermostat (low water), auto-reset overheat thermostat (low water) (auto-reset overheat thermostat is only on newer units with CS or RB serial number prefixes), pilot light, fill / vent valve, bellows assembly, pressure relief valve, temperature gauge, and reset button linkage assembly. B. Theory of Operation (See Figures 5- thru 5-). Electrical Operation Current flows thru the normally closed contacts of the overheat thermostat(s) (also known as the low water thermostat) to one side of the contacts on the timer switch. When the timer assembly is not set to a time, the timer switch contacts are not closed and no path to the heating element is completed. When the operator sets the timer assembly to any time setting, the timer switch contacts are closed allowing current to flow across the normally closed contacts of the temperature regulator relay and be applied to the heating element, causing it to heat up. Current is also applied across the pilot light causing it to illuminate, thus indicating that the heating element is energized. The diaphragm cup is pressure sensitive and expands outward as the pressure in the chamber increases. The normally closed temperature regulator relay is adjusted so the diaphragm cup will push open the contacts of the relay when the selected temperature / pressure is reached during a sterilizing cycle, de-energizing the heating element. When the temperature / pressure lowers slightly, the diaphragm cup contracts allowing the temperature regulator relay to close its contacts which causes current to be applied to the heating element and pilot light again. The temperature in the chamber is regulated to within + to + of the selected temperature during the cycle by the continuous opening and closing of the temperature regulator relay contacts by the diaphragm cup. The timer assembly contains a timer motor which runs the timer assembly. When the timer is run down to a setting of 0 minutes, the timer switch contacts move, breaking the circuit to the heating element and pilot light. A circuit to the timer buzzer is now completed, causing it to sound. The timer assembly timer motor continues to run for one minute. Then the timer switch contacts are opened, causing the timer buzzer to stop sounding. Midmark 99 SF-8 Rev. 5/95 Page - Printed in U.S.A.

7 SECTION I GENERAL INFORMATION During the cycle, if the temperature inside the chamber rises up higher than 85 F ( C), the normally closed manual reset overheat thermostat (also known as low water thermostat) contacts open, breaking the circuit to the timer switch, heating element, and pilot light. The most frequent cause of activation of the overheat thermostat is a low water condition in the chamber. The N.C. auto-reset overheat thermostat is a safety backup for the manual reset overheat thermost and opens at 95 F (6 C). The manual reset overheat thermostat is reset by pressing the RESET button located on front panel of the sterilizer and the auto-reset overheat thermostat automatically resets after approximately six minutes. Water / Air / Steam Flow The M7 sterilization cycle has four phases; filling, heat up, sterilizing, and venting. During the fill portion of the cycle, the operator depresses the FILL / VENT lever which opens the fill / vent valve. Water flows from the condensing tank thru the fill / vent valve and into the chamber. When the operator visually observes that the water level in the chamber is within / in. to 5/8 in. ( to 6 mm) from the front rim of the chamber, the operator releases the FILL / VENT lever, closing the fill / vent valve. Now the operator begins the heat up portion of the cycle by turning on the timer assembly. During the heat up portion of the cycle, the water is heated by the heating element. As the water begins to boil, air is bled off thru the bellows assembly into the condensing tank. When the bellows assembly senses pure steam flowing thru it, the valve in the bellows assembly closes, allowing pressure in the chamber to build. The sterilizing portion of the cycle begins when the bellows assembly is completely closed, not allowing steam to flow thru it, and the desired temperature in the chamber for the selected cycle is reached. The operator sets the timer assembly for the desired length of the cycle and the cycle is run. When the timer assembly counts down to 0 minutes and shuts off the heating element, the vent portion of the cycle begins. After the door handle has been moved to the vent position, the operator depresses the FILL / VENT lever which opens the fill / vent valve. Steam and water flow thru the fill / vent valve and into the condensing tank, venting the chamber. There is coiled tubing under water in the condensing tank which serves to turn the steam back into water. There is a pressure relief valve which opens if the pressure in the pressure valve reaches PSI ( kpa) during a cycle. This provides a safety relief for the chamber so that unsafe pressures cannot build. There is a temperature gauge on the front control panel which indicates the temperature inside the chamber during a cycle.. SPECIFICATIONS Factual data for the sterilizer is provided in Table -.

53 6. Introduction The illustrated parts list provides information for identifying and ordering the parts necessary to maintain the unit in peak operating condition. Refer to paragraph.5 for parts ordering information. The parts list also illustrates disassembly and assembly relationships of parts. 6. Description of Columns The Item column of the parts list gives a component its own unique number. The same number is given to the component in the parts illustration. This allows a part number of a component to be found if the technician can visually spot the part on the illustration. The technician simply finds the component in question on the illustration and notes the item number of that component. Then, he finds that item number in the parts list. The row corresponding to the item number gives the technician the part number, a description of the component, and quantity of parts per subassembly. Also, if a part number is known, the location of that component can be determined by looking for the item number of the component on the illustration. The Part No. column lists the MIDMARK part number for that component. SECTION VI PARTS LIST SECTION VI PARTS LIST The Description column provides a physical description of the component. The Qty. column lists the number of units of a particular component that is required for the subassembly. The letters AR denote as required when quantities of a particular component cannot be determined, such as: adhesive. Bullets { } in the Part No. column and the Description column show the indenture level of a component. If a component does not have a bullet, it is a main component of that illustration. If a component has a bullet, it is a subcomponent of the next component listed higher in the parts list than itself that does not have a bullet. Likewise, if a component has two bullets it is a subcomponent of the next component listed higher in the parts list than itself that has only one bullet. 6. Torque Specifications and Important Assembly Notes When specific assembly torque specifications, measurements, or procedures have been identified, by our engineering department, as required to assure proper function of the unit, those torque specifications measurements, and procedures will be noted on the parts illustrations. Adherence to these requirements is essential. Page 6- Midmark 99 SF-8 Printed in U.S.A.
