the Booster Pump Below Water Level and
close to the Sea Strainer, if installed.

The Booster Pump may be mounted either
horizontally or vertically. If mounted
vertically, the Wet End MUST be mounted
DOWN (on bottom). If mounted vertically
(with the wet end on top) the motor may
develop an electrical short should the wet end
of the Booster Pump leak. Connect the Booster
Pump inlet to the Sea Strainer Outlet or Sea
Cock valve, or if the Inlet Rinse/Clean Valve
is installed then connect the Booster Pump
Inlet to the Center (common) port of the Inlet
Clean/Rinse Valve [4]. Keep this line as short
and straight as possible. Avoid up and down

loops, 90° elbows, and hose kinks.

Fresh Water Flush Assembly

[53 & 54]***

May be installed anywhere in the feed line.
However, for optimum rinsing results this
Check Valve Tee must be plumbed into
the Feed Water Line immediately after the
Booster Pump outlet. Mount the Fresh Water
Flush System with the mounting hardware

included in the kit. With the supplied ¾"

I.D. Hose connect the Inlet port of the Check
Valve (bottom port) to the Outlet of the

Booster Pump. With the supplied ¼" O.D. tube

connect the solenoid valve inlet to the existing
pressurized fresh water system.

Plankton Filter

[6] (optional)

Must be mounted against a flat vertical surface
using the supplied mounting brackets and
hardware. Mount the assembly below water
level to minimize feed pressure loss. Allow

minimum 4" below the bottom of the bowl for

mesh screen element removal. Connect the
inlet to the Booster Pump Outlet or the Fresh
Water Flush Outlet.

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.

Connect the inlet to the Booster Pump Outlet
or Fresh Water Flush Outlet.

Connect the Outlet to the Commercial Pre-
filter 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 x 1/4 inch) first (on the bottom) then
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-ring sealed and requires only light
tightening to seal the O-ring.

Backwash Multi-Media Filter before operating
the system.

Standard Pre-filter

[12]:

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.
