How the toilet works
The requirements for the toilets to operate are a power source and propane, natural gas, or diesel fuel. They conveniently attach to 120/240V AC power, or 12V DC which can be recharged by solar power. The electricity powers the auger and commences the burn cycles.
To operate the toilet, one simply has to add a toilet liner to the bowl before waste flush (optional). After usage, one can rinse a little bit of water mixed with Royal Mist liquid (optional) before closing the lid and press one of the two flush buttons (urine or solid waste).
An auger will then feed the paper liner and waste into the burn chamber and shortly thereafter the burner automatically commences and the burn cycle is underway.
Since these models burn all the waste after each usage, there will never be any waste left inside the toilet that can cause unpleasant odor.
Depending on the SR model used, the process can take a few minutes for a quick urine cycle, or up to 30 minutes for a solid waste cycle. One of the great features of these units is that even though a burn cycle is in progress, one can still use the toilet. It will simply shut off the burning process when the toilet lid is lifted up. Once the lid has been closed again, it will resume the burn process and finish the burn cycle.
- Close toilet and press "urine" or "waste"
- Auger moves waste into burn chamber
- Burner ignites and starts incineration process
(Optional: chimney fan runs for 60 seconds)
- Display panel shows two green lights when cycle is complete
A control board monitors the amount of usage and its burn process. Indication lights display if the process has finished its burn cycles or if there is an error (such as being out of fuel). The panel also has the two flush buttons that one has to push in order to start the burn cycle.
The SR12 is heavy-duty, made to handle both higher capacity and a tougher environment than the SR5.
Maintenance / Cleaning
For regular usage, the ash from the toilet only has to be emptied periodically (depending on use). The chamber is easily accessible through a door located in the back of the toilet making the ash removal process simple, especially when vacuumed out of the chamber.
To ensure a clean bowl and auger, the toilet is equipped with a 1-quart reservoir of water which can be used to clean the bowl. One only needs to press a button to rinse the bowl. As an option, it is also possible to add a liner in the bowl before usage; the liner gets moved into the burn chamber along with other waste material. Once inside the chamber, the incineration process quickly eliminates the paper liner along with the waste.
Since these are waterless incinerating toilets, they operate in very extreme climates (hot or cold). No compost or chemicals are required. If the toilet has to be left for a length of time, simply shut down the power and fuel lines.
Safety & Emission
The toilet is a safe and convenient appliance when assembled and used properly. In order to provide a durable toilet, we have chosen high quality materials that are made to withstand high usage and a severe environment. During production, each toilet goes through several meticulous testing procedures which have been approved by Underwriters Laboratory (UL) and CE. Also, the toilet is equipped with multiple safety devices that recognize if any minor problems occur and shut off the unit. The toilets are equipped with very efficient burners that ensure reliability in operation and low emission.
Given that the toilet is completely self-contained, the installation process is easy and can be done in a few simple steps by a general contractor. It is important that the unit gets installed in a weather-proof building so it doesn’t get exposed to snow or rain. A minimum of 5 inches clearance from any wall is recommended, though 12 inches would allow easier access the burn chamber to remove ash.
The toilet includes an 8 ft chimney system (6” double wall pipe - 6” I.D, 8” O.D). It can go vertically or horizontally out through the roof/wall. When the chimney system has been installed, the next step is to connect the power supply and fuel (Propane, Natural Gas, or Diesel). The toilets can operate with a small BBQ propane tank or larger propane sources. The SR12 also operates with diesel or kerosene.
Included in Chimney System
- 8 ft Chimney Pipe
- Storm Collar
- Roof Support
- Chimney Cap
- EcoJohn Adapter
Depending on the installation, some optional parts may be required:
- Catalytic converter - a catalytic converter may be installed in the chimney pipe; the catalytic converter cleans the outgoing air and ensures that there are no harmful agents going out.
- Royal Mist liquid - a special liquid that can be added to the water reservoir - the Royal Mist takes out any bad odor (if any).
- Solar panels - can be installed with 12VDC batteries to ensure fully charged batteries
- Chimney fan - an extra fan may be installed in areas where extra draft is needed
