  • Page 3: General Description - 1.1

    General Description – 1.1 The BioMAT 2 Microbiological Safety Cabinet has been designed to provide optimum performance for both operator and product protection. Using the latest developments in microprocessor and fan technology, it is designed to exceed the performance requirements of the European Microbiological Safety Cabinet Standard EN12469:2000.

  • Page 4: Quality Assurance/Ce Compatibility

     Extension, modification, relocation, repairs or other maintenance is carried out by CAS personnel or persons authorised by CAS or, in the case of electrical work, by qualified electricians.  In the case of repair or maintenance, it is important OEM replacement parts supplied by CAS are used.

    NOTE: A lighting configuration of either interlocked or non-interlocked are generally factory set, however this can be amended on site by a CAS engineer if required during commissioning.  Should the sash need opening further than the 200mm point to load or unload equipment then the UP arrow on the control panel membrane should be used.

  • Page 13: Shut Down Procedure - 2.3

    Shut Down Procedure – 2.3  The work area should be cleared of any apparatus and equipment; it should be fully cleaned in accordance with laboratory codes of practice. The cabinet should be left running for a few minutes to ensure any residual aerosols are removed. ...

  • Page 14: Cleaning Procedure - 2.4

    Cleaning Procedure – 2.4 Regular cleaning is very important to prevent the build-up of dirt and hence potentially infectious material. Routine swabbing of work surfaces with 70% v/v IMS (ethanol) or IPA (Isopropyl Alcohol) is recommended. For cleaning the work surfaces swabbing with a mild detergent in warm water is very effective. Phenolic or Cresolic disinfectants should be avoided as they may stain the white surfaces with a brownish colour.

  • Page 15: Fumigation & Formalin Quantities - 2.5

    A convenient way of generating sufficient formaldehyde is to boil off Formalin (40% formaldehyde BP or equivalent) in a suitable vessel such as a formalin vaporiser. These are available from CAS. Always consult your Laboratory Safety Officer prior to fumigation of a safety cabinet.

  • Page 16: Fumigation Procedure - 2.6

    Fumigation Procedure – 2.6  Switch off the cabinet fans by pressing the green button ‘A’ on the control panel.  For re-circulating type safety cabinets, a fumigation extract kit (Optional Kit) should be fitted to the cabinet discharge. Ensure the manual damper or blanking plate is fitted and fully closed, this prevents any fumigant leakage from the cabinet discharge during fumigation.
  • Page 17 A VHP sterilisation cycle is available on the BioMAT 2, this would either be factory set or set by a CAS engineer at the time of commissioning. The VHP cycle when selected runs the down flow fans continuously at 50% of the normal speed, this ensures the air is cycled throughout the cabinet work area and fan &...

  • Page 18: Airflow Measurements - 2.7

    Airflow Measurements – 2.7 It is recommended that the downward airflow within the work zone is checked regularly, i.e. weekly or monthly according to cabinet usage. A calibrated rotating vane type anemometer with a head diameter of approximately 100mm is considered satisfactory. On 1200mm wide cabinets, take 8 readings, namely four along a line one quarter of the depth of the working space forward of the rear wall, and four along a line the same distance behind the front window on a horizontal plane 100mm above the top edge of the working aperture.
  • Page 19 Unidirectional Downflow Air NOTE: - The unidirectional Downflow air within the cabinet is set up during factory testing and checked again during on site commissioning to give an average velocity of 0.3 to 0.35m/sec measured at a horizontal plane 100mm above the top edge of the working aperture.

  • Page 20: Ultraviolet Radiation

    The required time for the UV can be factory set or alternatively adjusted to suit your requirements on site by the CAS commissioning engineer. Once the cycle as started and the pre-set time period is shown, +/-5 mins buttons will appear, these allow the UV cycle time to be increased or decreased to suit user requirements.

  • Page 21: Display - 3.1

    Display - 3.1 The cabinet display is located in the centre of the control membrane, this is a full colour touch sensitive TFT display; it incorporates airflow animations as well as written text to ensure the cabinet condition can be clearly seen from the operating position. Typical animation is displayed during normal safe operation, shown below: In the event of a low down flow alarm condition the display will clearly indicate the fault;...
  • Page 22 In the event of a low inflow alarm condition the display will clearly indicate the fault; the animation shown below will remain displayed until the fault is rectified. A low inflow alarm condition will automatically switch the down flow fans off, this helps to prevent any air escaping through the open front aperture.
  • Page 23 Should the cabinet produce an alarm condition it may be necessary to arrange for a CAS 0161- Service Engineer to attend site, in such cases please contact our Service Department on...

  • Page 24: Alarm Circuits - 3.2

    Alarm Circuits – 3.2 There are four standard alarm circuits on the BioMAT 2 Re-circulating, Exhaust and thimble Safety Cabinets. INFLOW Sensed by an accurate airflow sensor mounted in the exhaust module and connected via a control cable to the main PCB, this will sense low airflow caused by a fan failure or the accumulation of filter soiling, this information is then processed by the main PCB and an alarm condition is displayed on the TFT display.

  • Page 25: Electrical Protection - 3.3

    Electrical Protection – 3.3 Ensure the Safety Cabinet is isolated from the mains supply prior to opening access panels. Warning Fuses There are 10 fuses mounted on the printed circuit board, these are used to protect the various electrical circuits of the cabinet. The cabinet controls are housed behind the front control panel which is secured with two screws located across the bottom edge.

  • Page 26: Fan Speed Control - 3.4

    Changes can be made via the front TFT touch display through an integrated Engineer’s Menu. It is important that any changes to fan speeds must be made by a CAS service engineer or approved service provider, failure to do this may result in the warranty being invalidated.

  • Page 27: Engineer's Menu - 3.5

    To access the engineers’ menu the cabinet should have power connected and the cabinet switched off, the CAS home screen should be visible. The letter `A` of CAS should be pressed and held for more than 5 seconds, once the 5 seconds as elapsed the engineers menu will be displayed.
