The following examples are intended to assist the installer to match up the appropriate salt feed system, however every condition can not be absolute. Contact customer service for additional details if necessary.
Key 4 gallon w/pump model# 32,33-3003 (12,24vdc)
4 gallon siphon w/water refill model# 31-3002
2 gallon siphon manual water refill model# 31-3002
Condition 1:
The toilet uses pressurized fresh water to flush with.
Condition 2:
The toilet uses tropical (warm) external ocean water always to flush with, but travel to cold waters also.
Condition 3:
The toilet uses tropical (warm) external ocean water always to flush with and is not near a tributary (fresh water run off).(none normally required)
Condition 4:
The toilet uses external ocean water always to flush with, but we use the system in cold waters a large part of the time.
Condition 5:
The toilet uses external ocean water always to flush with, and the water temperature is varies.
Condition 6:
The toilet uses tropical (warm) external ocean water always to flush with, but sometimes travel to brackish waters.
What Does it Do?
The Lectra/San MC system requires ocean grade salt water in order to process properly. If the vessel is operated in brackish, fresh water, cold water or the toilet system utilizes on board fresh water to operate, there is a need to increase the amount of salt in the flushing water to operable levels that will allow the treatment units process to occur. The Lectra/San will not function if the amount of salt in the treatment unit is lower than its tolerable operating range. This is where the salt feed system becomes a necessary addition to the installation.
What are the differences in models? How They Introduce The Salt Solution The 4 gallon and 2 gallon siphon models use a “T” check valve in the suction line of the toilet (intake water) to dispense a manually adjustable amount of saturate salt solution every time the toilet is operated.The 4 gallon w/pump model incorporates a built in injector pump that dispenses the salt solution directly into the treatment unit. This is done only when the microprocessor of the treatment unit detects the need for additional solution.
How are they refilled?
The 2 gallon model must be manually refilled with a pre made salt solution. Estimated flushes before adding salt solution 10 – 25. (2 gallon installation guide)
Both of the 4 gallon models are connected to an onboard pressurized water source that automatically maintains the water level in the salt tank by the use of a float valve. This method allows salt crystals to be added directly to the salt tanks without the use of external manual mixing. Estimated flushes before adding salt crystals 50 -200.

Note: Manually adding salt solution directly in the bowl can be accomplished although it can be laborious. Adding salt to some manufactures toilet(s) is not recommended and, can cause damage to the toilet (check with toilets operating instructions or contact the manufacture). Use the 2 gallon salt instructions mixing procedure if manually adding salt solution.
