For special water conditions, e.g. iron content and recycled water, other media types
are available at lower flow rates – please consult our service department or your distributor

1. Weekly

  • Once a week perform a manual back flush, make sure that the differential pressure is
    below 0.25 bar (4 psi), after the back flush.

2. Monthly

  • Close valves at the inlet and outlet of filters.
  • Release pressure within the filter and open the top filling port.
  • Inspect media level and its cleanliness. If media is missing add to required level.
  • If the media is not effective anymore (long usage, or tough caking), perform chlorination treatment (see clause 3 bellow) or according to the following instructions.

REPLACING THE FILTER’S MEDIA

  • Replace the gravel when the amount of dirt (that cannot be back flushed), prevents proper functioning of the filter.
  • Close all the valves.
  • Open the filter drain plug, to release the pressure and to drain all the filter’s water.
  • Open the top filling port.
  • Open with care the side service ports.
  • Empty the gravel from the filter, through the side service ports.
  • Rinse the interior thoroughly with clean water.
  • Inspect the double bottom of the filter including the partition and the “mushrooms” diffusers.
  • Check the protective coating for damage and repair if necessary.
  • Close the side service ports with covers and tighten properly.
  • Fill the filter through the top filling port with the right amount of gravel – and shut the top filling port and tighten the cover properly.
  • Check the Flow Limit Valve, or readjust the Throttle Valve (F) Back flush the filter with the new gravel to wash out dirt and dust, for at least two minutes.
  • Open the valves for normal operation – (see installation) Maintenance Instructions

General Notes :

  • For efficient filtration the media should be crushed with sharp edges,.
  • Flow recommendation according to dirt load (for crushed granite and crushed basalt) :
  • 1. 75 m3/h/m2 (30 gpm/ft2) for average water condition.
  • 2. 50 m3/h/m2 (20 gpm/ft2) for dirty water.
  • For special water conditions, e.g. iron content and recycled water, other media types are available at lower flow rates – please consult our service department or your distributor.
  • Minimum media grain size: 0.6 mm.
  • 1. Weekly
