Biolan Simplett can be installed directly on floor surface and it is suited for both indoor and outdoor use. Biolan Simplett is odourless, hygienic and environmentally friendly. The functioning of the toilet is based on the separation of liquid and solid waste in the seat part. No water or power supply is needed. The receptacle is easy to empty.

The operation of the Simplett is based on the separation of solid waste and liquid in the seat part. The toilet requires neither water nor electricity supply.
The Simplett Dry Toilet shall always be used in the seated position to enable the liquid and the solid matter to be separated.
When using the toilet for the first few times, pay attention to your sitting position to direct the urine in the correct way. Remember to also instruct your guests on how the toilet should be used. In addition to the toilet waste, you can also put toilet paper and decomposing facial blotters into the Simplett toilet.
You must not put the following into the toilet:
Applying suitable bulking material is essential for proper operation of the toilet. For bulking material we recommend Biolan Compost and Toilet Bulking Material or Biolan Ground Peat. Before using the toilet, place a layer a couple of centimetres thick on the bottom of the inner receptacle. Do not add bulking material until after defecation.
When the inner receptacle of the toilet fills up, empty it into the composter. If you use a biodegradable bag inside the receptacle, place the content and the bag separately into the composter in order to intensify the decomposing. You can place a piece of newspaper on the bottom of the receptacle under the bulking material.
Empty the liquid tank, when necessary. In every case, empty it in the autumn in order to prevent it from breaking due to the frost. Urine is very rich in nutrients, especially nitrogen. It can be used in the garden, right away diluted in water in a ratio of 1:5 or as such, after having left it standing for three months.
For the sake of hygiene, the solid toilet waste, emptied from the Simplett dry toilet, must be composted before utilising it in the garden: for at least one year before applying to edible plants, and for about half a year before applying to ornamental plants. You can compost the toilet waste either as such or together with garden waste and domestic waste. While composting, observe the local regulations on waste handling, and consider sufficient protective distances to neighbours, wells and nearby bodies of water. Burying waste in the ground is prohibited. Composting toilet waste always requires a solid composter with a cover. For example, Biolan Garden Composter or Biolan Stone Composter are suitable for the purpose.
All parts of the Simplett dry toilet can be cleaned using any common domestic cleaning agent. The parts of the toilet can be disassembled, and, if you disconnect the liquid removal and ventilation pipes, you can even take the unit out. Wash the liquid bowl at the top and the liquid funnel. Flush the liquid pipe with warm water and a mild detergent or crystallised sodium at least once a year to remove any precipitate that the urine may have formed.
Install the Biolan Simplett at a level position on the floor. When deciding where to locate the unit, take into account the space required for its ventilation and liquid removal arrangements, as
well as its use and maintenance. The unit must be placed so that the top cover of the tank can be opened wide enough to enable easy emptying.
If you install the Simplett toilet in a warm space, you may use it all year round. Then, its ventilation and liquid removal systems must be insulated in cold spaces, and the liquid removal pipe must be provided with a sufficient gradient to prevent the liquid from freezing in the pipe. If the liquid is collected in a canister, the canister must be emptied in the autumn in order to prevent it from breaking due to the frost. A toilet located in a cold space can be used occasionally during the winter. The Simplett is manufactured of frost-proof materials, so freezing does not damage it.
Install the horizontal ventilation pipe in the unit. Observe that the end of the pipe must extend to above the inner receptacle to enable the water, that may possibly condense, to flow into the inner receptacle.
Leading the ventilation pipe through the rear wall. Make a lead-trough hole of at least Ø 75 mm, according to the dimension drawing for the horizontal ventilation pipe. The hole to be made in the wall must be located slightly higher than the hole in the unit to prevent the condensed water from remaining in the pipe. Cut the horizontal ventilation pipe to a suitable length so that the angular union used will be connected to the vertical ventilation pipe with a curve as gentle as possible. Make sure that the pipe will be located inside the toilet. Extend the horizontal ventilation pipe to above the roof ridge, using a sewer pipe of Ø 75 mm. The Ventilation Pipe Package, which is designed for the purpose, is available as an accessory from the dealers. A suitable pipe can also be obtained from HVAC stores and well-appointed hardware stores. We recommend using a rounded angular union. Any extra bends in the pipe will impede natural ventilation, and may cause odour problems. If you want, you can improve the ventilation by using the Biolan Wind Fan.
The ventilation pipe can also be routed up through the roof inside the toilet space following the instructions above. The lead-though in the roof can be sealed, for example, using the lead-through set for the roof. The lead-throughs are available as accessories from hardware stores.
Connect the liquid funnel (part 8) to the liquid pipe (part 7), and install the funnel in the bracket (part 6)(Fig. 3) inside the unit. Route the liquid removal pipe by the inner receptacle through the hole in the rear part of the unit. The pipe is flexible, and its length can be adjusted by pulling at the ends. If the space is not provided with a sewer, make a hole of at least Ø 43 mm in the rear wall or in the floor for the liquid removal pipe (part 7)(Fig. 4).
Route the liquid pipe into a closed canister, tank or the sewer system. Observe, when dimensioning and selecting the location for the liquid tank, that the amount of urine excreted per person and day is about 1–1.5 litres. During installation of the liquid pipe, remember to provide a sufficient gradient (2–3 cm/m) to enable the liquid to flow down without obstruction. Therefore, the hole to be made in the wall must be located lower than the hole in the unit. If you want, you can lay the canister on its side or bury it in the ground.
You can ask your dealer to order the Canister Package and parts for extending the liquid pipe. The pipe can also be extended using sewer pipe parts of Ø 32 mm. We recommend using connecting
sleeves in the joints.
