INTRODUCTION
The Four Gallon Salt Feed System with Pump is
designed for boats that operate in fresh or
brackish water and can only be used with the
Lectra/San®MCTM. Salinity is monitored by the
Lectra/San MC Control Panel and salt solution will
automatically be added to the Lectra/San when
needed.
Pressurized freshwater is required. Minimum of 15
psi (103 kPa) working pressure.
Additionalpartsincluded: Heatsinkfortransistor
(Fig.#4),strappingfortankandsaltfeedpumpcable
with terminals.
Additional parts required: Mounting hardware,
shutoffvalve,plumbingfittings,1/2"(12.7mm)hose
for pressurized water and 3/4" (19mm) hose for
overflow.
OPERATION
Solar salt is added directly to the tank. Water
suppliedbytheboatspressurizedfreshwatermaintains
the water level in the tank and continues to make
saturated salt solution from the solar salt. A pump is
used to add salt solution directly into the LST/MC
treatmenttankwhenneeded. Thepumpiscontrolled
by the LST/MC circuit board that monitors the
electrode current in the LST/MC treatment tank and
automaticallyturnsonthepumpwhensaltisrequired.

be displaced through the overflow tube. The water
level will drop back to its normal level after a few
uses.
WINTERIZING
1. Rinse tank thoroughly with freshwater and wipe
out tank.
2. Shut off pressurized freshwater, disconnect and
drain pressurized freshwater line.
3. Rinse salt feed pump, tubing and check valve

INSTALLATION/ MOUNTING
Locatesaltfeedsystem within twelve feet (3.6 m) of
and on the same level as LST/MC treatment tank.
Makesuretankisaccessibleforrefilling. Securesalt
feed tank (Fig. #1).
PLUMBING
1. Drain and empty treatment tank for an existing
system. If new system, perform following steps
before installing treatment tank.
2. Drill a 3/8" hole in treatment tank lid (Fig. #2).
3. Glue tank lid adapter (#31-325) in 3/8" hole
drilled in treatment tank lid using PVC cement
per PVC cement instructions.
4. Removelidfromsaltfeedtankbypullingsidesof
lid up.
5. Remove packaging insert and unwrap salt feed
pump.
6. Placesaltfeedpumpinholeattheendof mounting
adapter located at the bottom of salt feed tank
(Fig. #5).
7. Install tubing from salt feed tank to check Valve
and to fitting on the Lectra/San treatment tank
lid. Be sure arrow on check valve points toward
the Lectra/San treatment tank (Fig. #3).
8. Install overflow hose to bilge.
9. Connect pressurized freshwater with a shutoff
valve to the barbed nipple at the bottom of the
tank (Fig. #3).
10. Turn on water and check for leaks.
11. Fill tank with solar salt.
WIRING
WARNING: Hazard of Electrical Shock.
Disconnect Power at source before proceeding.
1. Remove control module cover (#31-460) from
treatment tank.
2. Installheatsink(#EHST0220)ontransistor(Q7)
located on the circuit board (Fig. #4), making
surethattheheat sink is not contacting any other
component. Theheatsinkfitsinonlyoneposition.
IMPORTANT:
A. DoNotuse excessive forcewheninstallingthe
Heat Sink.
B. Some components of the circuit board are
sensitive to static discharge. Proceed using
careandobservingantistaticprecautionssuch
as grounding straps on wrist and touching
ground frequently to discharge body static.
3. Connectsaltfeedpumpcable toLST/MCcircuit
board (Fig. #4). Connect red wire to terminal
U14 and black wire to terminal U15.
4. Replace control module cover and reconnect
electrical power.
