Sun-Mar Excel-NE (Non Electric)

The Excel NE has no fan or heater. Odorless operation is achieved by a 4" vent mounted at the top rear of the unit which acts like a chimney on a wood stove. For good air movement the vent should be installed vertically and to 2-3 feet above the peak of the roof. An optional 12 Volt Fan should be installed if the Excel NE is used residentially or heavily, is in a place which is subject to down-draft, or if you need to install the toilet with any bends in the vent. No more than 2 45° bends are encouraged, even with the fan. This fan draws 1.4 watts and can be powered by a solar panel and 12 volt marine battery.

Evaporating capacity on the Excel NE is variable, so the 1" drain at the rear should be connected to an approved drain pit, container, or other facility.
