    Reporting • It is vital for SciCan to learn of any problem in the field. This information will help SciCan solve the problem quickly and improve product reliability in new units. Biological waste • Waste water in the unit may contain biological contaminants; use a mechanical means to siphon the contents.

  • Page 13: Shipping Instructions

    Shipping instructions The unit should be serviced on site. If it is necessary to send the unit back to the dealer, follow these instructions: 1. Drain water from the unit. Follow these steps:...
  • Page 14 2. Remove residual water from the water cooling system. Follow these steps: Remove the Venturi water reservoir filter. Insert siphoning tool into each drainage hole and pull residual water from the system. 3. Screw in the leveling legs. 4. Specify upright, heated, and insured shipping. 5.

  • Page 15: Location And Installation

    2. LOCATION AND INSTALLATION The STATCLAVE G4 will require a support surface that is strong enough to hold the weight of a fully loaded unit with full reservoirs (a total operating weight of 175 lbs / 79.5 kg). The space should also allow room for the door to open correctly, for the top reservoir lids to be opened for filling and for ventilation on the right side.
  • Page 16 Open the bag and, with one person on either side, grip the strap handle and underside of the unit to lift and remove it from the base packaging. Unlatch the unit door to open it and remove items stored in the chamber. Check the contents. (See Checking package contents, in this section.) With the unit still on the floor, connect the power cord.

  • Page 19: Electrical Connections And Power

    IMPORTANT: For the unit to function, BOTH reservoirs must be full and BOTH drain tubes must be connected. The STATCLAVE G4 uses water from the Venturi reservoir to generate vacuum draws at the beginning and end of each cycle. For the unit to operate, BOTH the clean water reservoir and the Venturi reservoir must contain the minimum required water levels.

  • Page 26: Functions And Cycles

    3. FUNCTIONS AND CYCLES The STATCLAVE G4 is a dynamic air removal (pre-vacuum) table-top steam sterilizer that uses steam to sterilize wrapped and unwrapped instrument loads typically used in dental and medical offices. It has six validated sterilization cycles with optimized drying for fast, effective instrument processing. An additional custom cycle can be configured using one of three temperature settings but this cycle must be validated by the user.

  • Page 27: System Icons And What They Mean

    System icons and what they mean The home screen contains four system icons. Press these icons to access additional functions and information.

  • Page 29: Unlocking The Door - Power On

    Unlocking the door – power on The STATCLAVE G4 will lock the chamber door when you select a cycle. To unlock the door, go to the home screen and follow these steps.

  • Page 31: Cycle Chart And Descriptions

    Cycle chart and descriptions When selecting a sterilization cycle, users are instructed to choose according to the recommendations of leading infection control authorities and local regulatory guidelines.

  • Page 32: Running A Vacuum Test

    Test cycles Running a vacuum test The vacuum test checks the sterilizer’s plumbing system for leaks. Run this test with the rack and empty trays in the chamber. IMPORTANT: Vacuum tests must be conducted when the unit is cool. Running a vacuum test on a hot chamber may cause the test to fail.

  • Page 33: Running A Bowie-Dick Test

    Running a Bowie-Dick test The BOWIE-DICK test is used to ensure proper air removal is occurring in a pre-vacuum autoclave. Complete air removal is important because pockets of cool air remaining in the chamber can compromise sterilization. Using an FDA-approved Bowie-Dick test pack, the Bowie-Dick test runs a cycle at 134°C for 3.5 minutes to evaluate the correct air removal.

  • Page 34: What Happens During A Cycle

    What happens during a cycle The STATCLAVE G4, like all autoclaves, uses various combinations of time, temperature, and pressure to make up different cycles that are designed to sterilize specific load types. Each cycle is divided into various phases. Some cycles may have more or less phases depending on the needs of the load type. For example, a cycle for hollow instruments will have an additional vacuum draw phase before sterilization to ensure steam penetrates every hollow of every instrument in the load.

  • Page 38: Retrieving Cycle Information Using The Usb Data Back Up

    Retrieving Cycle Information Using the USB Data Back Up The USB storage device can be used to transfer cycle information stored in the unit to a computer. Best practice suggests this should be done once a week. To transfer data using the USB port, follow these steps: When the activity light on the USB storage device stops blinking or the USB icon on the LCD turns from a flashing green to a solid grey, remove the USB storage device and transfer the information to your computer.

  • Page 45: Setting Up Load Traceability With User Id, Pin, And Process Enforced Usage

    The Process Enforced function keeps track of who has started and who has removed a load from your STATCLAVE G4. It does this by prompting users to enter a PIN at the start of a cycle, when they STOP or CANCEL a cycle, and when they REMOVE a load.

When you press the Calibration button to start the calibration cycle, the following screen will appear. IMPORTANT! When this screen appears, the POA field will be highlighted and you will have 30 seconds to complete the POA calibration before the cycle continues to the vacuum phase.
  • Page 69 To complete the POA calibration, compare the pressure reading on the display (P) with the pressure reading on the pressure reference meter. (See the following Step for a full explanation of the calibration screen.) Adjust the pressure reading using the up or down arrows on the POA offset field. NOTE: The difference in two readings should be within 0.5Kpa.
  • Page 70 NOTE: The POV offset will be adjusted again at Step 26 of the calibration process when the unit reaches a pressure (vacuum) value in the region of 20kPa (30kPa or less). 17. On completion of the vacuum phase, the unit will go back to atmospheric pressure. Check the readings between the unit’s pressure display (P) and the pressure reference meter.
  • Page 71 If your values DO NOT match the values, stop the procedure, tighten all the calibration fittings and start a new calibration. STAGE 6. Adjusting the unit pressure and temperature 21. Wait until the cycle reaches the sterilization phase (temperature above 132°C). 22.

  • Page 72: How To Back Up The Calibration Data

    30. After removing the calibration fitting, install a new test plug to close the test port. Open the door and switch off the unit. Calibration is now complete. How to back up the calibration data To back-up the calibration data (which is saved automatically) for future references using the Backup NVRAM feature, follow these steps: Power the unit OFF.

  • Page 73: Diagnostics And Troubleshooting

    Using the device screen The STATCLAVE G4 has a number of sensors and systems that are constantly reading and generating values. These sensors and systems can be seen on the device screen, a diagnostic tool found in the service menu.
  • Page 74 The device screen is divided into four groups (see image below). Section A is for monitoring all systems. The values displayed here are generated in real time. Section B is for checking the heating systems. To verify the functioning of either the steam generator (TSG) or the top and bottom band heaters (TBHT and TBHB), you can use the arrows to the right to increase the temperature in that component to a specific target temperature and then watch the corresponding reading in Section A to see if the component successfully reaches the target temperature.
