(EN) INSTRUCTIONS FOR USE
1. PLANNING AND INSTALLATION
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.
FI
1.1 Technical specifications
• depth 560 mm
• width 525 mm
• sitting height 480 mm
• height 515 mm
• weight 8 kg
• size of the inner receptacle 28 l
• external diameter of the liquid removal pipe 32 mm
• length of the liquid removal pipe 335 mm–935 mm
1.2 Year-round use of the toilet
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.
1.3 Ventilation
Installing the horizontal ventilation pipe
Install the horizontal ventilation pipe (part 2) 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 (see Fig. 3).

Leading the ventilation pipe through the rear wall
Leading the ventilation pipe through the rear wall (Fig. 4). Make a
lead-trough hole of at least Ø 75 mm, according to the dimension
drawing (Fig. 1) 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 as shown in Fig. 3.
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.
Liquids rich in nutrients must not be allowed to
enter the soil as they cause an excessively concentrated nutrient load.

Ventilation pipe in the toilet space
The ventilation pipe can also be routed up through the roof inside the toilet space following the instructions above (Fig. 5)
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.
1.4 Liquid removal
Installing the liquid funnel and the liquid pipe
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).
Draining the liquid
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.

2. USE AND MAINTENANCE OF THE
SIMPLETT
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:
• sanitary towels, debris
• chemicals, lime
• detergents, washing water
• ash, cigarette butts, matches
2.1 Using bulking material
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 (part 11). Do not add bulking material until after defecation.
Fig. 5
Please consult your local refuse disposal
advisor for regulations on composting.

2.2 Emptying the inner receptacle
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.
2.3 Emptying the liquid tank
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.
2.4 Composting solid waste
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.
3. PROBLEMS THAT MAY OCCUR
3.1 Odour
If odour problems occur, check that there is no liquid at the bottom, under the inner receptacle. If there is liquid, check the connections of the liquid pipes, and as required, wash the internal
parts of the unit (see point 2.5). You can also prevent the odour
problems by pouring a small amount of water into the liquid funnel after each time the toilet is used. Also remember to cover the
excrements with a sufficient amount of bulking material.
3.2 Insects and maggots
If flies, for example, appear in the toilet space, empty and wash the
inner receptacle and check that the body is clean (see point 2.5).
Do away with any flying insects in the toilet space using pyrethrin-based spray. Consult your local dealer to select a suitable
product. Also ensure that the ventilation is adequate, and that a
sufficient amount of bulking material has been applied.

2.5 Cleaning
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 (part 8). Flush the liquid
pipe (part 7)
lised sodium at least once a year to remove any precipitate that
the urine may have formed.
