Electrode Pack, Every six months
1. Flush the system for 60 seconds to clean out the
Treatment Unit. Operate one treatment cycle.
2. If the Treatment Unit is mounted below water level,
disconnect the hose from the vented loop on the
Treatment Unit side of the loop. Drain any excess
liquid from hose into a pan for disposal.
Clean out vent line
3. Remove the discharge hose and use a hand or electric
pump to remove as much liquid as possible. Allow
time for liquid to drain past electrode pack partition.
4. Either remove Treatment Unit cover, remove electrode pack,
and clean plates with a small stiff brush.
(but not a wire brush) or
5. Turn off head inlet valve and pump bowl as dry as possible.
Add one pint of concentrated muriatic (hydrochloric)
acid to a two gallon plastic bucket full of water.
Pour the solution into the toilet bowl and pump head
as dry as possible, so solution is forced into the
treatment tank. Allow the solution to work at least
45 minutes in the treatment tank. DO NOT ACTIVATE
TREATMENT SYSTEM when acid solution is in the
treatment tank. After 45 minutes have elapsed, flush
the head in the normal manner, the equivalent of at
least 10 flushes to thoroughly wash out the acid.
NOTE: The purpose of the acid treatment is to remove calcium
carbonate deposits which tend to build up in all marine
heads and their connecting plumbing. The build ups occur
whether or not a treatment system is installed.
VIII. Storage
A. WINTER STORAGE
The LECTRA/SAN Salt Feed Unit and Treatment Unit should be prepared for winter storage according to the following instructions:
Salt Feed Unit
1) Remove tubing from salt feed tank and toilet, and remove metering plug. Wash out tubing, siphon check valve. and metering plug with fresh water.
2) Wash inside of salt feed tank with soapy water. Rinse
thoroughly with fresh water
3) Reconnect salt feed unit and store empty and dry.
Treatment Unit (Procedures a and b which follow can be used)
a. WET STORAGE
1) Close the control valve on the salt feed tank.
2) Flush the toilet for at least 60 seconds to clean out the Treatment Unit without activating the LECTRA/SAN treatment cycle.
3) Close the inlet seacock. Remove the inlet hose from the toilet
pump assembly.
4) Temporarily attach a short length of hose to the inlet pump where the permanent hose was removed. Place one end of the hose into 2 gallons of "permanent-type" antifreeze (propylene glycol), placed in a bucket. Flush the toilet until all the antifreeze has been delivered and bowl is nearly dry. A total of two gallons of antifreeze is required to properly protect the system. DO NOT USE "ANTI-LEAK" ANTIFREEZE.
5) Close the outlet seacock and reconnect the inlet hose to the
toilet pump assembly.
6) Let the antifreeze remain in the system until the boat is re-commissioned.
Warning:
NEVER USE ALCOHOL OR KEROSENE TO WINTERIZE LECTRA/SAN.
NEVER ACTIVATE THE LECTRA/SAN TREATMENT SYSTEM WHEN GLYCOL IS IN THE TREATMENT UNIT. BECAUSE THE REACTION OF HYPOCHLOROUS ACID AND GLYCOL CAN GENERATE HEAT, WHEN RECOMMISSIONING THE BOAT. OPERATE THE HEAD AT LEAST TWO MINUTES TO FLUSH OUT ALL TRACES OF GLYCOL IN THE TREATMENT UNIT BEFORE ACTIVATING THE TREATMENT CYCLE.
b. DRY STORAGE
1) Same as a (1) above
2) If the Treatment Unit is mounted below water level, disconnect the hose from the vented loop on the Treatment Unit side of the loop. Drain any excess liquid from hose into a pan for disposal.
3) Either remove the cap from the top of the Crossover/Separator and use a hand or electric pump to remove all the water from both compartments of the Treatment Unit.
OR
Remove discharge hose from the treatment unit and using a hand or electric pump, pump out as much water as possible from the treatment unit. When it is obvious that the water level in the treatment unit is lower than the inlet ports, remove either the hose fitting, Part #41 -17 or the inlet plug, Part #41-19 and pump out any remaining water.
4) It is recommended that the electrode pack be inspected and cleaned Remove the cover of the Treatment Unit and pull out the Electrode Pack, Rinse the electrodes with fresh water and clean the plates with a stiff brush (but not a wire brush) or soak the electrodes in dilute muriatic acid for about one hour and then brush clean after rinsing. Replace Electrode Pack and re-secure Treatment Unit cover.
B. RECOMMISSIONING
When recommissioning the boat in the spring from wet storage, open both seacocks and flush the toilet for two minutes to purge the system of all the antifreeze solution. Alternatively, a manual or electric pump can be used to clean out both chambers of the Treatment Unit through the Crossover/Separator or Discharge Elbow.
The LECTRA/SAN System is put back in operation by following the Start-Up instructions given in Section IV
WARNING: IT IS VERY IMPORTANT TO HAVE COMPLETELY FLUSHED
THE SYSTEM OF ANTIFREEZE BEFORE OPERATING LECTRA/SAN.
THE CHEMICAL REACTION BETWEEN THE DISINFECTANT
AND ETHYLENE GLYCOL CAN GENERATE HEAT.
IX. Materials Required to Install LECTRA/San
The following materials are not supplied and are needed to mount the LECTRA/SAN System:
Material for Securing Treatment Unit.
TEFLON TAPE or PIPE SEALING COMPOUND (non-hardening)
PVC (polyvinyl chloride) CEMENT, SILICON CEMENT.
1 1/2" ID NEOPRENE or PLASTIC HOSE for connecting Treatment
Unit to toilet and to the through-the-hull discharge fitting.
l 1/2" HOSE CLAMPS (4)
OPTIONAL:
Vented Loop. 1 1/2" Dia.
1/4" Plastic hose to Vent loop overboard
The size of power wires and connectors needed to wire the LECTRA/SAN System are given below:
Wire Size Solder-less Crimp Style
