Hi Art,
You can press one, the other or both. The toilet will evacuate faster than the raw water comes in even if you hold both buttons down. You are trying to limit the input water, this is the whole purpose of using a separate supply. This gives you the ability to put water in the bowl first if the situation dictates. It makes the toilet flush cleaner just like at home.
Not programmable, These are simple monetary on/off buttons. Push the out button and the macerator part runs, you can tell when the bad stuff is gone by the change in sound. Push the in button and the Surflo water pump puts raw water in the head, you can watch it fill, Really simple. I did a cut and paste on Defender catalog for a switch that does the job, ( you only need one because you get one with the SeaEra conversion),
Below is a Defender Catalog cut paste for a pump, and an Amazon cut paste for the SeaEra conversion.
Also, Here is a link to the exploded parts view for the Raritan Sea Era conversion.
www.raritaneng.com/wp-content/uploads/20...215SeaEraExpview.pdf Take a look, you remove assembly #162000W on the last page of the drawing – easy, 4 long machine screws. Then when the motor turns only the extraction and macerator part because the raw water fill pump is gone.
The IP 350 toilet output plumbing stays the same it can be directed into the tank or overboard depending on how the valve is set. Do you have a Macerator installed?
