“Section E” Installation
(common) port to the Inlet of the Booster Pump
[5].
6. Booster Pump [5]
The Booster Pump is a centrifugal pump and it is
not self-priming. The booster pump volute must
be fully filled with water in order for the booster
pump to operate properly. Any air present in the
pump prevents the water from flowing.
Mounting the booster pump below water level
ensures that air never enters the booster pump
volute. For best results, install 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.
7. Fresh Water Flush Assembly
[53 & 54]***
From Pressurized
Fresh Water System
To Pre-filtration
Inlet.
From Booster
Pump Outlet
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.
8. 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.
