INTRODUCTION
The Lectra/San and ElectroScan do not require a salt
feed system when operating in ocean water with a
salt content of 3.5%. A salt feed system needs to be
utilized if operating in fresh or brackish water. This
system can be used with all Lectra/San or ElectroScan
models. Low salt is indicated on the unit’s Control
Indicator Panel. Salt can be added to the Lectra/San
using a Four Gallon Salt Feed Tank. For dimensions
see Fig. #1.
Additional parts included:
Strapping for the tank.
Additional parts required:
Mounting hardware,
shutoff valve, plumbing fittings, 1/2” (12.7 mm)
hose for pressurized freshwater and 1/2” (12.7 mm)
hose for overflow.
Pressurized freshwater is required. Minimum of 15
psi (103 kPa) working pressure.
OPERATION
Solar Salt is added directly to the tank (see refill
-
ing salt in the system). Water supplied by the boats
pressurized freshwater maintains the water level
in the tank and continues to make a saturated salt
solution from the solar salt. Every time the toilet is
flushed, a portion of the salt water solution is mixed
with incoming water to increase water salinity in the
Treatment Tank. A Low Salt indication on the unit’s
Control Indicator Panel will indicate time to refill
tank with more salt.
The amount of saturated salt solution entering the
Treatment Tank can be decreased or increased by
adjusting the plastic tubing clamp (#31-304C). To
FOUR GALLON SALT FEED SYSTEM (Part #31-3005)
Installation and Maintenance Instructions
decrease the amount of salt solution entering system,
adjust plastic tubing clamp to pinch tubing restricting
flow. To increase the amount of salt solution, release
plastic tubing clamp to remove restriction. (See
Start Up section for more details). When operating
in proper salinity, close the plastic tubing clamp to
avoid unnecessary drain of salt solution from the tank.
Reopen plastic tubing clamp when needed.
Refilling salt in the system:
Add up to 20 lbs. (9kg)
of solar salt directly into tank. Some water may be
displaced through overflow tube. The water level
will drop back to its normal level after a few uses.
NOTE: Before refilling tank with solar salt, check
the filter screen (#31-313) and make sure it is clean
(see Fig. #2).
