INTRODUCTION Steri-Vac 8XL Sterilizer Modes of Operation
Methods of Selecting Modes and Options
The Steri-Vac 8XL Sterilizer provides four modes of operation.
There are two methods of selecting Steri-Vac 8XL Sterilizer modes and options. The modes are selected by setting DIP switches, specifically SW1 switches 7 and 8. The options available in the modes are either selected with a softkey or by configuring SW1 switches 1-6. Softkey selections are evident when described in the procedures. DIP switch settings are described and a picture is provided to show the switch positions. Figure 1 shows the relationship between the positions of the configuration switches on SW1 or SW2 and the configuration tables used in the procedures. The arrows correspond to the following: ↑ Closed, ↓ Open. Figure 2 shows the Steri-Vac 8XL Sterilizer Controller Card configuration switch, test point, and connector locations.
Normal Mode - The sterilizer is operated in Normal Mode when performing routine sterilization operations. The procedure on page 9 provides instructions on placing the sterilizer in Normal Mode. For detailed instructions on operating the sterilizer in Normal Mode see the Operator’s Manual. Service Mode - The Service Mode is used to: •
Set up the sterilizer when it is initially installed, or when there is a change to the setup information. Critical options are set during setup.
•
Check out the sterilizer when it is initially installed or if a problem is encountered during operation. Checkout provides instructions for the Calibration of temperature, pressure, and RH sensors; vacuum test, switch test, and video test; and printing setup and trend information.
•
Troubleshoot various sterilizer problems by running selected stages of a sterilization cycle and printing trend reports for analyzing failures. Additionally, troubleshooting includes error analysis and error clearing procedures.

CHECKOUT Temperature Calibration (Automatic) Automatic Temperature Conditioning Circuit Calibration (Auto Cal) should be performed first, then, if necessary, the individual temperature sensors can be adjusted. The temperature conditioning circuit contains a precision resistor calibrated to 47.5°C. The software calibrates the conditioning circuit (not each individual sensor). The equations for determining the actual temperature are adjusted according to the value read from the calibration resistor. 1. Using the Up and Down softkeys, highlight TEMPS on the Sensor Calibration menu. 2. Press the Select softkey.
3. 4.
Using the Up and Down softkeys, highlight the AUTO CAL on the Temp Calibration menu. Press the Select softkey. Auto calibration is performed.
Notes: The Help window (page 43) can be viewed to check calibration. Calibration (CAL) should be 47.5º ±.5º.
5.
Each temperature sensor can be calibrated independently of the others. This is only required if temperature problems occur, such as the middle of the chamber is too hot or too cold as compared with the end temperatures. Normally individual calibration does not need to be performed. If none of the temperature sensors require individual calibration, press the Done softkey and the Sensor Calibration menu is displayed. Otherwise continue with the next procedure.

SPECIAL CYCLES Accelerate Cycle This SW1 DIP switch controllable option allows the service representative to accelerate the time of selected stages of a cycle by 120 during a sterilization cycle, in the normal operating mode (1 hour will equal 30 seconds). See table at right for specific elements of the cycle that are accelerated. The acceleration DIP switch can be actuated anytime during the sterilization cycle, usually before the cycle starts. If the DIP switch is set to accelerate during a cycle, the time for the current stage will not be accelerated. During a cycle, times are first calculated then the stages are performed. After a stage has started, the only way to accelerate that stage is to cycle the power. When the sterilization cycle restarts, the acceleration option is detected and the new time is calculated. If the accelerated option is changed to non-accelerated during an accelerated cycle, the accelerated time continues until the next stage starts.

4XL, 5XL, and 8XL
Condition:

N/A
Solution:
This Bulletin is written to describe the Final Checks and procedures that must always be performed on the sterilizer before the sterilizer is put back into use.
Check #1:
Temperature Calibration
Use either the 49C method or the 2231 Ohm resistor method. Temperature Calibration Procedure Using the 49C Method (Preferred method on all sterilizers)
1. Put the Fluke thermocouple under the TCO on a 5XL or near the chamber temperature sensor on a 4XL. Use silver tape to attach thermocouple, if needed. Use Thermal Grease on the Thermocouple / Chamber interface to insure good heat transfer. DO NOT place thermocouple under the Chamber High Limit Thermostat on a 4XL. 2. Put the unit in cycle and allow the display to go to 51 C. 3. Then turn power off, set DIP SW1-1 and SW1-3 to the up position, and allow the temperature (on the fluke) to go to exactly 49 C. At that point, turn the unit on and it will calibrate to within a couple of tenths of a degree of true accuracy. (The door latch will activate indicating acceptance of the new calibration.)
Health Care/3M
Page 1 of 4
Distribution Limited To Current 3M Approved Service Providers 4. Turn power off and set DIP Switch SW1-1 and SW1-3, down. 5. Turn power on. Unit will come up in a C3, and the unit will continue in cycle. 6. Observe the display and Fluke to insure the temperatures match. If OK, remove the thermocouple and press stop button to terminate cycle. If temperature on Fluke and on the display do not match, repeat steps 1 – 6.
IMPORTANT NOTE: If machine will not accept the calibration (vacuum pump comes on instead of latch activation), the machine is too far out of calibration to accept the 49 C. To correct, observe the display when the Fluke reaches 49 C. If above 51 C, calibrate the temperature in 2 C increments until between 51 C and 49 C. Then make final calibration to 49 C. If the temperature of the chamber reaches 51 C, and the Fluke is below 49 C, the 2231 Ohm resistor method must be used to calibrate the temperature.
Temperature Calibration Procedure Using the 2231 Ohm Resistor (Recommended when had to change the controller board on 4XL and on old 5XL, just to get close to correct temperature. Then use above method to get accurate calibration.) 1. Take the 2231 ohm variable resistor from your tool case and insert the ends into the multi-meter (common and Ohms), set to read resistance. Adjust resistor until the multi-meter reads 2231. 2. Measure the temperature of the chamber by placing the thermocouple near the location of the chamber temperature sensor. Attach Thermocouple with Silver Tape if needed. Add Thermal Grease to thermocouple / chamber interface to insure good heat transfer. Start a warm cycle, and allow the temperature to stabilize at 55C. 3. Note the difference between the actual chamber temperature measured by the thermocouple and the displayed temperature. This is the amount you want to offset. (For example, suppose the actual temperature is measured as 53C, 2 degrees lower than displayed. If more than 2C offset, see NOTE below.) 4. Disconnect the chamber sensor at the connector and put the 2231 ohm resistor leads into the connector end that goes to the controller board, not the connector end that goes to the sensor. The display will now read 48C. 5. Adjust the resistor until the display reads the offset temperature correction. (For this example the actual is 2 degrees lower (See #3), so the resistor should be adjusted until the display reads 50C).
Health Care/3M
Page 2 of 4
Distribution Limited To Current 3M Approved Service Providers
6. Turn the power off. Place DIP switches 1 and 3 Up and turn the power on again. This now calibrates the temperature. 7. Turn the power off again, remove the variable resistor and reconnect the chamber temperature sensor. 8. Place DIP switches 1 and 3 down again and turn the power on. The calibration procedure is complete. Recheck the chamber temperature to see that the actual temperature is the same as displayed. 9. If the temperature is now close, within 1-2 degrees C, use the 49C method described in the first section to precisely calibrate the temperature. IMPORTANT NOTE: If the actual temperature is more than 2C offset from the displayed temperature, the calibration can not be accomplished in one calibration. The above calibration procedure will have to be done more than once, adjusting the temperature 2C at one time. THE CALIBRATION WILL NOT BE ACCOMPLISHED IF MORE THAN 2C OFFSET IS ATTEMPTED.
Check #2:
Proper Default Temperature on Display Panel
1. Cycle Power 1 time a. Check return to default cycle. b. If not at customer requested default, i.e. warm cycle or cold cycle, change default. When power is cycled on a 4XL or old 5XL, the unit will default to the temperature it was set on during the last in cycle power interruption. This can be a problem if the service rep interrupts power on a cold cycle and the customer runs only warm cycles. To correct this, simply cycle power after servicing to make sure the unit defaults to warm (or cold if the customer wants to default to the cold cycle). If it doesn’t, you can select the desired default cycle, start the cycle and turn the power switch off and back on. Press Stop to get an E40, open the door and press Stop again. Check for proper default by cycling power again.

Check #3:
After Regulator Re-build or Replacement
Adjust air pressure up 5 psi to account for drop across new diaphragm. Use caution with questionable air quality.
Check #4:
Run Last Cycle (5XLe and 8XL only)
Run last cycle information and check printout for any abnormalities.
Check #5:
Run Accelerated Cycle
Run Accelerated cycle. Make sure cartridge is punctured properly.
Check #6:
Final Power Test
After side panel is back on, cycle power and start a cycle. Allow machine to run for 30 seconds, check printout and make sure machine is going into cycle. If OK, press Stop, and clear code.
Check #7:
Personnel Discussion
Discuss any abnormal information with appropriate hospital (facility) employee (Biomed, Maintenance Manager, etc.)

4XL, 5XL and 8XL EO Gas cartridges May 18, 2004
Machines Affected: All 4XL, 5XL and 8XL sterilizers Condition:
Damage to the Labels on the Gas cartridges.
Cause: Solution:
Liquid EO escapes around the cartridge seal and melts the Label. Perform the following procedure.
Note: This issue may occur if liquid ethylene oxide leaks around the cartridge guide seal and damages the shrink-wrapped label surrounding the Steri-Gas cartridge. Consequences are discoloration and / or deterioration of the shrink-wrapped label and staining of the sterilizer. There is no safety risk, as the Ethylene Oxide is released only in the closed Steri-Vac chamber. After sterilization, the gas is removed by the normal aeration cycle. The functionality of your 3M Steri-Vac Sterilizer will not be compromised. Standard sterilization monitoring procedures will help to ensure an adequate sterilization cycle. Future lots of Steri-Gas cartridges will not have shrink-wrapped labels. 1. Loosen the setscrew or screws that secure the cartridge guide in the cartridge well of the Steri-Vac chamber. 2. Remove the cartridge guide and the cartridge seal. Discard the old seal. 3. Install the new seal in the cartridge well. Use part number 12-2376-2845-3 for the 4XL and 5XL and part number 78-8078-3324-5 for the 8XL. 4. Be certain that the seal is properly oriented. ( see Fig. 1)
Fig. 1
5. Check the 8XL cartridge holder for proper spring tension. They are located at the top of the cartridge holder. They should hold the cartridge securely in place.

Subject:
4XL,5XL and 8XL Chamber Leaks
Date:
December 3, 2004
Machines Affected:
All 4XL, 5XL and 8XL sterilizers
Condition:
Chamber vacuum leaks.
Cause: Solution:
The chamber does maintain the proper vacuumduring testing Perform the following procedure.
STERI-VAC STERILIZER CHAMBER VACUUM LEAK ISOLATION The Steri-Vac sterilizer chambers are required to maintain a vacuum level through out the exposure portion of the cycle. The permissible level of vacuum loss during exposure depends on the model of sterilizer. The 4XL and 5XL sterilizers are allowed to have a 40 millibar leak in 10 minutes. The 8XL sterilizer is allowed to have a 15 millibar leak in 10 minutes. The primary source of chamber leaks is the chamber check valve. Clean or replace this component first. Then perform a leak test. To conduct the leak tests refer to the leak test procedures described in the respective Service Manuals. A kit of plugs, part number 78-8069-7680-5, is available to assist in isolating the vacuum leak. Compressed air is used to perform several functions during the operation of the sterilizer. Failures of the sealing surfaces in the compressed air components can allow compressed air to leak into the chamber and appear to be a vacuum leak in the new 5XL and 8XL The 4XL and old 5XL will not experience leaks from compressed air components although they may leak ambient air into the chamber. Isolate the source of a leak in the chamber by eliminating the compressed air components as a possible source. The following procedure will eliminate the compressed air components. 1.
Perform the leak test as described in the Service Manual. Perform the “Dead End Vacuum Test”. If you cannot obtain a dead end vacuum of less than 100 millibars, the leak source could be located in the fittings on the chamber side of the chamber check valve or at the fittings around the pressure sensor and puncture solenoid valve. Note the leak rate of the dead end vacuum tester. If there is a rapid loss of vacuum when the test is stopped, the leak may be located in one of these areas.
2.
Continue with the chamber leak test. If a leak is detected, re-run the test but during the 10 minute dwell time, disconnect or turn off the compressed air and bleed the air from the compressed air line for the new 5XL or 8XL.
Health Care/3M
Page 1 of 5
Distribution Limited To Current 3M Approved Service Providers 3.
If the leak continues at the same rate the leak is not caused by the compressed air components.
4.
If the leak has stopped or been significantly reduced, one or more of the compressed air components is faulty.
5.
The puncture solenoid valve, which is used to switch between compressed air and chamber vacuum for the operation of the puncture cylinder, can leak compressed air into the chamber on the new 5XL and the 8XL. The solenoid valve plunger, seat or dirt could cause the leak.
6.
Remove the puncture solenoid valve and the 1/8 inch NPT nipple from the “T” fitting and plug the hole with 1/8 inch pipe plug, part number 26-1014-7121-2. Check the “T” fitting for cracks. (see Fig. 1) If cracks are visible, replace the “T” fitting.

Perform the leak test again. If the leak rate is reduced replace the solenoid valve assembly. If the leak is not reduced continue the procedure.
8.
The puncture cylinder can leak compressed air into the chamber on the new 5XL or 8XL. A plug, part number 78-8083-0419-6, is available to eliminate the puncture cylinder. Install the plug and o-ring.
9.
Perform the leak test again. If the leak is reduced or eliminated replace the puncture cylinder. If the leak is not reduced continue the procedure.
10. The 4XL and old 5XL sterilizers will not experience a compressed air leak from these components. However, there could be an ambient air leak through these components. Following steps 6, 7, 8 and 9 can isolate leaks in these components. If the leak is not reduce or eliminated the leak is in another area of the sterilizer. 11. On the new and old 5XL and 8XL disconnect the tubing that connects the cartridge well to heatsink and use a ¼ inch tube compression plug, part number 78-8005-7373-1 to seal the cartridge well port. 12. Remove the tubing from the heatsink to the chamber, one port for the 5XL and 2 ports for the 8XL. Plug the chamber port(s) with the ¼ inch tube compression plugs, part number 78-80057373-1. 13. Run the leak test again. If the leak is reduced or eliminated a leak exists in the heatsink assembly. . If the leak is not reduce or eliminated the leak is in another area of the sterilizer. 14. If the leak is in the heatsink assembly, examine the components for cracks or bad seals around the compression fitting ferrules. The ferrules should not turn on the tubing. Also check the vent solenoid valve and the moisture solenoid valves and tubing. 15. On the 4XL sterilizer replace the 6 o-rings on the heatsink coupling, check the vent solenoid valve and the tubing to the moisture solenoid valve for bad seals around the ferrules. Note: There are several ports through the chamber wall. Some of these ports have brass bushings that can crack if the components connected to them are over tightened.

16. If the leak continues, examine the bushings that go through the chamber walls. Look for hairline cracks in the brass. (see Fig. 2) If there is a doubt replace the bushing with an appropriately sized plug, which is usually a 3/8 inch NPT plug, part number 26-1011-7274-5.

Fig.2 17. The new 5XL and 8XL have humidity sensing components that could also cause a chamber vacuum leak. Isolate these components using a 3/8 NPT plug, 26-1011-7274-5, at the chamber connection and a ¼ inch NPT plug, 12-7992-5759-2, at the check valve connection. 18. Perform another leak test. If the leak is reduced or eliminated, the leak is in the humidity sensing components. Examine the flex tubing for any cracks. Replace the tubing if there is a doubt. Be certain that the Exhaust ports (EXH) for the 5XL and the Atmosphere port (ATM) for the 8XL solenoid valves are connected to the chamber side of the fittings not the sensor side of the fittings. 19. Reinstall the humidity sensing components and perform another leak test. If the leak continues, the door gaskets are the last repairable source. The old and new 5XL and the 8XL have gaskets on the back panel of the chamber as well as the load door side. 20. Examine the load door gasket for any cuts or tears. Over time, continuing vacuums in the chamber flattens the gaskets. Once the lips of the gasket are flattened to the level of the rim around the chamber, the gasket may not seal consistently. 21. If the gasket is flattened, replace the door gasket using proper procedures described in Technical Bulletin 74 and Equipment Bulletin 45. 22. The back plate gasket can be tested without removing the back plate. Remove the outside cabinet panel from the sterilizer. 23. Use a thin (0.010-0.020 inch) plastic or steel ruler or feeler gauge to test for good contact of the gasket to the back plate. 24. Draw a deep vacuum in the chamber. Observe the gasket contact to the back chamber plate. Look at the corners to be certain that the outer lip of the gasket is making contact with the back plate. 25. Slide the ruler or feeler gauge along the edge of the gasket that is against the back plate. Use only slight pressure against the gasket. When an area of poor contact is found the ruler or feeler gauge will slip between the gasket and back plate and there will be a whistling or screeching noise as air leaks past the gasket. The corners are most often the problem spots. (see Fig. 3)

Fig. 3 26. If no noise is heard the gasket is probably OK. However, if all other tests have failed to solve the problem, replace the gasket and perform another leak test. 27. Go through this entire procedure at least twice before considering the chamber to be defective Note: Be certain to use Teflon tape on all pipe thread fittings and plugs to insure a good seal. Do not over tighten pipe thread fittings as the brass fittings will stretch or crack causing additional leaks. By using good workmanship practices and observation techniques, most sources of leaks can be found in a reasonable time.
