The Sun-Mar Centrex 1000 Central Composting Toilet System is ideal for those who have electricity. Designed for light to medium seasonal use by families of up to 7 (5 adults), the Centrex 1000 is typically able to hold compost for the full season. Compost needs extraction only in the spring.
The Centrex 1000 features a 260-Watt heater in a sealed compartment under the unit, a 35-Watt turbo fan, and a 2" vent stack to ensure odorless operation. Also included is a 1" drain hose that should be connected to the 1" drain at the bottom left of the unit.
The included fan and heater run on AC power (115V). An AC/DC conversion kit is available separately above, which allows the Excel to operate in either 12-volt DC or non-electric mode. The toilet will continue to vent through the 2" vent using AC power when available, and will switch to a new 4" vent stack (included in the AC/DC kit) when AC power is not available. An optional 12-volt fan (included in the AC/DC conversion kit) can be installed in the 4" vent to use DC power to assist with venting.
The Centrex 1000 is designed only for use with one or more Sun-Mar Low-Flush Toilets (available separately above).
