IV. Initial Startup

Important: Do not operate the LECTRA/SAN without water
           in the treatment unit. To make sure the
           treatment unit is full of water. Flush the
           head until water runs out the discharge
           fitting. Note that on page 5 it is mentioned
           that you postpone slipping the discharge hose
           in place Now secure the hose on the barbed fitting.

A. FILL SALT FEED TANK
It has been stated previously that in many cases the salt feed tank may be dispensed with. However, if it is decided that it is more convenient to use the salt feed tank on a routine basis, it is best to mix a saturated solution of table salt (cannery's salt is better) in a separate container and refill the salt feed tank from time to time as required. This will eliminate the possibility of un-dissolved salt lying in the bottom of the salt feed tank and subsequent clogging of the valves. Pour only the clear brine into the salt feed unit

8. ADJUST CONTROL VALVE ON SALT FEED TANK

To assure adequate treatment, the meter needle should indicate within the green sector.
Set the salt feed control Valve to the position shown in the following table in order to establish the initial salt feed rate. Select the valve position for your type of dockside water.

C. FILL TREATMENT UNIT *
If the boat is in salt water -- before using head, flush the head until water runs out outlet fitting as previously explained. Make sure outlet hose is then secured. If the boat is in fresh water, pour eight ounces (one cup) of table salt down the bowl and add three gallons of water. With the toilet inlet valve shut off, flush the salt and water to fill the treatment unit.
  * Be certain discharge seacock is open before system is operated.


D. TEST OPERATION
Give the knob on the Control Unit a clockwise turn until it "clicks" to activate LECTRA/SAN for a test treatment cycle. Check for the following conditions:
1) Flush/Pre-treat operating light "on"" (Mixer motor operates
throughout entire treatment cycle).
2) After about one-half minute, the treatment cycle begins; treatment meter registers and both operating lights should be "on".**
3) Indicating needle should show in the low to mid-point of the
green (normal) area.
4) After a total of about two and one-half minutes, treatment cycle ends; operating lights go off and meter reading goes to zero.

E. ADJUSTING THE CONTROL VALVE ON SALT FEED TANK
When the boat is in fresh or brackish water, it is necessary to bring
up the salinity of the flush water to the equivalent of normal seawater. This may be done by introducing the concentrated brine in the salt feed tank to the inlet fresh water. (As shown in Fig. 3 & 4). On pure fresh water, the control valve will have to be full open. On brackish water, the Valve may be partially closed.
The correct amount of brine will be indicated by the position of the control unit meter needle. The meter needle should read within the green sector to assure adequate treatment.
The full cumulative effect of any valve adjustment will be indicated on the meter only after several uses. This is because water in the Treatment Unit must be replaced by flush water of the new salt concentration. The motors will be overheated by repeated rapid sequencing. Adjustments should be made by flushing in the normally spaced periods of 5 minute intervals.

* The operating light will not go on if a fuse is blown. Refer to Section VI, Troubleshooting for corrective action

V. LECTRA/SAN OPERATION

A. GENERAL
The two operating principles of LECTRA/SAN are:
  1) Reduction of solid waste to indiscernible particles: and
  2) Oxidation of waste matter and destruction of odors and bacteria.
LECTRA/SAN operation is automatic. The user has only to activate the system with a clockwise turn of the knob on the Control Unit before flushing the toilet.* This starts the mixer motor and turns on the Flush/Pretreat operating light. The toilet is then flushed with the minimum amount of water required to clear the bowl. Salt, if needed. is automatically fed from the Salt Feed Unit to the flush water as the toilet is being flushed. As wastewater is pumped from the toilet to the Treatment Unit, previously treated wastewater is discharged from the second chamber of the Treatment Unit.
When the flush/pretreat cycle, which lasts about 35 seconds, is complete, the system automatically switches to the treatment cycle at which time the solids reduction motor and electrodes are activated.** Disinfecting agent is generated to oxidize the waste and destroy bacteria and odor. The treatment cycle continues for two more minutes at which time the operating cycle is complete and the system automatically shuts down. During the two minute operating period a small amount of by-product gas, similar to battery gas, is formed and is discharged through the effluent line. There can be no accumulation of gas because LECTRA/SAN operates completely filled with water. The toilet can be used during the treatment cycle, but the flush must be deferred until the operating lights are "off.
The oxidizing and disinfecting agent is produced by passing electricity through the conductive salt water solution in the LECTRA/SAN Treatment Unit. Although LECTRA/SAN operates on the principle of electrolysis, extensive testing has shown that electrolytic corrosion of metal boat fittings does not occur.

* LECTRA/SAN Is designed not to operate unless the Control Unit knob has been turned a full 240" to engage the timer. When turned fully, a "click" will be heard and the top light will go on.

** It is normal for the motors on the Treatment Unit to be hot to the touch after an operating cycle. The toilet should be flushed only during the flush/pretreat cycle and never during the treatment cycle.


C. OPERATING INSTRUCTIONS
Instructions for operating LECTRA/SAN are given below:

1) Before flushing toilet, start the LECTRA/SAN System with a clockwise turn of the knob on the Control Unit until it "clicks".  A full (240") turn of the knob is required to engage the timer and turn on the Flush/Pretreat light.

2) Flush the toilet with the minimum amount of water required to clear the bowl. This will normally take six to ten seconds with an electric toilet. With a manual flush toilet, pump the flush handle vigorously until bowl is clear.

3) After about two and one-half minutes, the operating cycle will be complete and the system will automatically shut down.
(See Note Below).
4) The toilet is now ready for the next use.
5) The toilet can be used during the treatment cycle, but the flush  must be deferred until the operating lights are "off" and the  system is activated again by a clockwise turn of the knob on the Control Unit.
