Customer Reviews For This Product
The EXCEL NE is a non-electric version of the EXCEL, the highest capacity self-contained toilet and the preferred self-contained model for heavy cottage or continuous residential use. The EXCEL NE was first launched in 1981, and it has long been the standard toilet for those living off the grid. Because it is a non-electric unit, the EXCEL NE does not have a fan or heater, like the EXCEL electric unit does. Odorless operation is achieve by a 4" vent mounted at the top rear of the unit which acts like a chimney on a wood stove by drawing air into the toilet and maintaining a partial vacuum within the unit. The EXCEL NE is also waterless, which means it's easy to install because there's no plumbing required. There is a 1" drain at the rear of the unit that should be connected.
If the EXCEL NE is going to be used residentially or heavily, or if it's in a location that may be subject to downdraft, an optional 12 Volt fan should be installed in the vent stack. This fan draws 1.4 watts and can be powered by a solar panel and/or 12 Volt battery. The optional 12 Volt fan is sold separately.
The EXCEL family of self-contained composting toilets are the world's only self-contained units to be NSF certified to operate odorlessly and producing a clean, dry compost. When you purchase an EXCEL, you are literally purchasing the unit that sets the standard for self-contained composting toilets!
How to operate the EXCEL NE:
- For initial start up, add some Compost Sure (peat bulking material) into the Bio-Drum™ together with some Microbe Mix.
- Use any toilet paper you want; the composting toilet will compost it without a problem.
- For ongoing operation, add Compost Sure as specified in the product instruction manual. Every 2-3 days (while unit is in use), rotate the drum 5 or 6 full revolutions. For weekend use, just rotate before you leave at the end of the weekend.
- When the Bio-Drum™ is half to 2/3 full, some of the compost should be moved to the finishing drawer. To do this, simply release the drum lock and rotate the drum backwards. Finished compost drops automatically into the finishing drawer. This process takes less than a minute, and most importantly, you never come into contact with fresh material.
- When compost is moved to the finishing drawer, it should be left there for at least 4 weeks so it can finish and sanitize. In the finishing drawer, it will be isolated from contamination by fresh material in the toilet. Once 4 weeks have passed, you can remove the finished compost from the finishing drawer at any time. The drawer is easily pulled out by hand; no tools are needed to open it.
- What do you do with the finished compost? Add it to your flower garden! The finished product is clean, dry, non-offensive, and sanitary. It will look and smell just like any other regular compost that might come out of a garden composter.

Reviewed By: Nancy Ressa
We
are very happy with the Sun-Mar toilet. We have had as many as 30
people use it on weekends. We have been using it 5 years with no
problems. It is everything you said it would be. We are pleased.
