Raritan 31-3005 User manual

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 ttings, 1/2” (12.7 mm)
hose for pressurized freshwater and 1/2” (12.7 mm)
hose for overow.
Pressurized freshwater is required. Minimum of 15
psi (103 kPa) working pressure.
OPERATION
Solar Salt is added directly to the tank (see rell-
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
ushed, 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 rell
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
ow. 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.
Relling salt in the system: Add up to 20 lbs. (9kg)
of solar salt directly into tank. Some water may be
displaced through overow tube. The water level
will drop back to its normal level after a few uses.
NOTE: Before relling tank with solar salt, check
the lter screen (#31-313) and make sure it is clean
(see Fig. #2).

WINTERIZING
1. Rinse tank thoroughly with freshwater and wipe
out tank.
2. Shut off pressurized freshwater, disconnect and
drain pressurized freshwater line.
3. Rinse tubing screen and T-Check valve assembly
thoroughly with freshwater.
INSTALLATION/ MOUNTING
Locate salt feed tank within six feet (1.8 m) of and on
the same level as toilet. Make sure tank is accessible
for relling. Secure salt feed tank (see Fig. #1).
PLUMBING
4. Attach T-Check valve in intake line (suction) of
toilet (see Fig #3).
5. Attach tubing to T-Check valve.
6. Modify intake check valve of toilet.
NOTE: Following part numbers refer to toilet
parts and not in the T-Check valve. When
connecting to a PHII, remove #1201 and #LWS;
for Crown Heads remove #CH12 and #CH8; for
Crown Head II and Atlantes models replace #RCV
with T-Check valve provided.
Other types of toilets need not be modied unless
they have an additional built in check valve.
7. Install overow hose to bilge.
8. Connect pressurized freshwater with a shutoff
valve to the barbed nipple at the top of tank (see
Fig. #3).

START UP
Refer to Start Up procedure outlined in the Lectra/San
or Electro-Scan Manual. The following instructions
are supplementary to those instructions (see Fig. #3).
1. Check plumbing connections.
2. Turn on water supply.
3. Check for leaks.
4.. Fill tank with solar salt.
How to adjust the salt solution: Open plastic tubing
clamp completely. Flush toilet several times then
run a treatment cycle. There should be no low salt
indication. See Owner’s Manual for specic system to
see how low salt is indicated, as it varies from model
to model. Use Troubleshooting if low salt indication
continues. With no low salt indication start closing
plastic tubing clamp until low salt indication comes
on and open plastic tubing clamp slightly again for
optimum salt without low salt indication. Flush toilet
four times between each adjustment.
