Multi Media Filter [6]:
Backwashing:
When the Media Filter becomes packed with
suspended solids, it must be backwashed. This
process unpacks the silica sand and dislodges the
suspended solids from the sand.
If replacing the media, the Multi Media Filter
requires approximately 15 lbs (7 kg) of small
gravel (1/8 x 1/4 inch) on the bottom then
approximately 26 lbs (12 kg) of #20 silica sand on
top of the small gravel.
To backwash the Multi Media Filter: Open the
Inlet Sea Cock Valve [2]. Position the Inlet
Clean/Rinse Valve [5], if installed, to the normal
operating position towards the Sea Strainer [3].
Position the Multi Media Filter Valves (3 each
valves) as shown in the diagram on the right for
Multi Media Filter Back Wash. Press the “Booster
Pump” switch. Allow this back washing to
continue for 10 minutes.
After 10 minutes of back washing press the “Stop”
switch to stop the Booster Pump.
Position the Media Filter Valves as shown in the
diagram below for Multi Media Filter Rinse.
Press the “Booster Pump” switch. The Booster
Pump [5] now rinses the Multi Media Filter [7] to
waste [11].
After 5 minutes of rinsing press the “Stop” switch
to stop the Booster Pump.
Position the Multi Media Filter Valves as shown in
the diagram below.

Pre-filter Element Replacement:
The pre-filter
elements must be cleaned, or replaced, when
plugged to the extent that the Low Pressure Gauge
at the control panel reads below 10 PSI. At or
slightly below 6 PSI the Low Pressure Switch shuts
the System off. The standard Pre-filters and the
commercial Pre-filter are both discussed on the
following page.
