3.3    Cleaning Methods
One of the following methods of maintenance should be used for the servicing of these Enviropod Filters:
.     Hand Maintenance.




3.3.1 Cleaning using Inductor Truck


The following steps indicate a safe and efficient method to clean the Enviropod using an Inductor:
      1.   Open gully pit. (See Section Error! Reference source not found.)
      2.   Place the inductor hose over the material collected in the filter bag and switch on the inductor.
      3.   Using the inductor hose suck all of the sediment, organic leaf material, litter etc., collected in the filter
           bag
      4.   Allow the filter bag to be sucked up into the inductor hose for a few seconds to allow for the filter
           mesh pores to be cleaned. Care is to be taken by the operator not to damage the filter, i.e. ensure that
           there are no sharp edges on the inductor hose.
      5.   If material has built up around the overflows, use the inductor hose to clear the accumulated material.
      6.   Remove filter bag from the pit.
      7.   Sediment retained in the gully pit grate is to be removed.
      8.   Back opening channels are to be cleared of any debris to ensure flow is not hindered. Debris can be
           collected using the inductor truck.
      9.   All gully pit waste is to be removed from the pit.
      10. Check the Enviropod unit. (See Section 0)
      11. Check filter bag. (See Section 0)

      12. Reinstate filter bag and gully pit lids.
