     Cleaning recommendation for DRG filter Elements:


     1. Ultrasonic cleaning

    The contaminated filter element is immersed for approx. 90 - 120 minutes, preferably  x      in an upright position (with/without turning), in the ultrasonic bath and then rinsed
    with clean detergent. Carefully blow out the filter element with compressed air,
    working from the clean side outwards. Suitable detergents are cleaner's solvent
    and similar products.

     2.       Manual cleaning – only suitable for filter sizes of 40 µm and larger.

     2.1.    Place the filer in a separate cleaning container and remove all loose dirt with             brush/paintbrush and cleaner's solvent or similar product.

     2.2.    Let the filter element soak for approx. 20 minutes in a clean detergent bath.

     2.3.    Rinse the filter element with clean detergent from the clean side outwards.

     2.3.1. Carefully blow out the filter element with compressed air, working from the   xxxxxxxx  clean side outwards.

     For both methods, it is important to prevent any dirt entering the inside (clean side)
     of the element.
     Do not use pointed or sharp-edged implements as they could damage the wire mesh.        These methods are however not suitable to achieve proper cleanliness in filters
     of 25 µm and finer. As a result, their service life will be gradually reduced!


     When do I need to change a filter element?

     For filters with visual or electrical service indicator:

     When starting the unit while it is still cold, the high viscosity of the medium might
     push  out the red button of the indicator, triggering an electric signal.
     Wait until the system has reached its operating temperature and then push the
     red button back in.     
     If it is immediately pushed out again, or if the electric signal does not drop off the
     moment the operating temperature is reached, you must change the filter element
     at the end of the shift.
     We recommend keeping a stock of original MAHLE spare parts.
     Disposable elements (Mic, KS-Mic, PS and Sm-x) cannot be cleaned.
