9. Multi Media Filter [7] (optional) is supplied pre-
mounted to its own base. Mount the Multi Media
Filter base onto a flat horizontal surface and secure
the base in place using the supplied mounting
hardware. Mount the assembly below water level to
minimize feed pressure loss.

Must be mounted against a flat vertical surface
using the supplied hardware.
It is preferable to mount the Standard Pre-filters
in a straight line with and in close proximity to
the Booster Pump.
Allow minimum 4" below the bottom of the bowl
for Pre-filter Element removal.

Inlet. Connect the Media Filter Waste Discharge
Fitting [10] to the Over Board Dump Waste
Fitting [11].
Unscrew the Multi Media Fill Plug, located on
top of the Multi Media Filter Lid. Place a funnel
over the Fill Hole. Pour into the funnel
approximately 15 lbs (7 kg) of small gravel (1/8

approximately 26 lbs (12 kg) of #20 silica sand
last (on top of the small gravel). Remove the
funnel and clean the Fill Plug female threads.
Screw the Fill Plug back onto the Lid and tighten
lightly with a wrench. Note this Fill Plug is O-
