1. Planning and installation
InstalltheBiolanNaturumatalevelpositionontheoor.Donot
attachthetoiletunittotheoor.Finelyadjustthepositionusingthe
adjustable shoes under the unit's front edge.
The toilet unit is equipped with connectors for drainage and ventila-
tion. When designing, observe explicitly whether the liquid needs to
be gathered into a collecting tank or a treatment facility, the ventila-
tion of the sewer, and the thermal insulation of the ventilation and
drain systems in cold spaces.
The method for post-treating the solid waste should also be care-
fully planned, to enable easier servicing of the unit.
1.1 Space requirement of the toilet
When planning the location for the Naturum toilet, make sure to
reservesufcientspaceforitsoperationandmaintenanceaswell
as for routing of the ventilation pipe and drained liquids The rec-
ommendedminimumoorarearequiredforinstallationoftheunit
perpendicular to the wall is 80 cm x 140 cm, but if set at an angle
in a corner, 130 cm x 130 cm.
1.1.1 Taking through the doorway
It is possible to take the Naturum through a doorway at least 67-
cmwidewithoutdismantling,providedthatitisrstturnedontoits
side. With its front jacket removed, the unit can be taken through
a 65-cm wide doorway or, if disassembled into two parts, even
through a 55-cm wide doorway (Fig.1).
1.1.2 Removal of the front jacket
• Undo the 7 attachment screws of the jacket.
• Removetheleverfromtheseparatingapbypullingthelever
straight off the unit.
• Depress the pedal, and pull off the jacket. Reassemble in the
reverse order.
1.1.3 Disassembling into two parts
• Remove the front jacket, as described above.
• Loosen the screws of the drum's side supports.
• Remove the screws of the upper drum cover support.
• Disconnect the liquid removal pipe from the drain trap.
• Undo the lower bolts of the drum cover (Fig. 2).
• Detach the hold and draw springs (Figs. 3 and 4).
• Pull the wires out from their groove.
• Starting from the lower part, twist off the drum cover from its
place (Fig. 5).
• Lift the drum off the bearing.
• Reassemble in the reverse order.
• Finally, tighten the drum bearing under the rear air vent at the
rear of the unit (Fig. 6). The rear air vent can be removed by
turning (Fig. 7).
1.2 Planning and installing the ventilation
system for the toilet
1.2.1 Joining up the ventilation pipe
Join up the ventilation pipe in accordance with the parts drawing
(see page EN-5). Cut the pipe to be connected to the unit by sawing
it to the correct length so that the ventilation pipe succeeding the
exiblepipegoesuprightalongthewall.
1.2.2 Natural ventilation
Route the ventilation pipe from the Naturum as a separate line
straight above the roof. You can also connect the ventilation pipe
tothesewerventilationor toanunused chimneyue. Soas not
to disturb the circulation of air, do not install the Naturum close
toareplace in activeuse.Werecommendalwaysusingthe Ex-
haust Ventilator (see Accessories on page EN-10) in connection
withindoorinstallations.Thisensuresthattheairalwaysowsin
the correct direction irrespective of the prevailing weather condi-
tions. Locate the Exhaust Ventilator instead of the lower connector
sleeve (part 46).

1.2.3 Mechanical extract ventilation
If the property is equipped with mechanical extract ventilation sys-
tem, connect the Naturum to the air-exchange channel (see p. 4).
Restricttheairowto1-2litrespersecondtopreventtheNaturum
from becoming too dry. This can be achieved using, for example, an
iris-shutter (works like the aperture control of a camera). Do not use
a separate fan.
When connecting the Naturum to a mechanical extract ventilation
system, do not provide it with a separate exhaust air duct, because
the mechanical extract ventilation overrides the Naturum’s own
system.
1.2.4 Mechanical supply and extract ventilation (heat
recovery system)
Because the air exchange is almost in balance, the most recom-
mendable solution is to connect the Naturum to a ventilation chan-
nel of its own (refer to the point Natural ventilation). Boost the venti-
lation by means of the Exhaust Ventilator (see Accessories on page
EN-10).Makesurethatthereissufcientreplacementairsupplied
to the toilet space either by the replacement air vent or from under
the door from the living space.
As the outlet air from the Naturum is not clean (compared, e.g, with
the kitchen), we do not recommend connecting the unit to a me-
chanical supply and extract ventilation system. For whatever rea-
son, should you wish to connect the Naturum to the extract chan-
nel,restrict theairowto 1-2l.p.s., for example,by means of an
iris-shutter (see page EN-2).
1.2.5 In general
We recommend that plastic ventilation channels be used for dry
toilets.
The pipe should be of plastic at least all the way to the iris-shutter
or the air outlet valve.This way, the metal pipe is protected against
the corrosive compounds (acids or alkali) that evaporate from the
Naturum in small amounts. When the iris-shutter is used, the moist
air rising from the Naturum is condensed at the shutter. To drain
any condensed water, install the air pipe so that it slopes from the
shutter towards the toilet unit.
In new buildings, the planning of the dry toilet system
constitutes a part of the general HVAC planning, and
building permission shall be gained by submitting a rel-
evant plan to the local building supervision authority in
the municipality where the property is situated.
For older properties the permission procedure depends
on the extent of the renovation work required and nor-
mal practice in the municipality where the property is
situated. Consult the local building supervision author-
ity for details.
When locating the toilet in an existing room space, ad-
vance planning is even more vital. It is recommended
that the plan be drawn up by a professional so as to
ensure the overall functionality of the system.

2.1 Before use
Remove the protective plastic from around the product. Note that
theseparatingap(part5)isalsocoveredwithplastic.
Beforestartingtouse,emptyapartoftherstchargebagintothe
toilet.Asuitableamountofrstchargeisabout20litres.Dosethe
moist rst charge mass through the seat opening into the drum
while simultaneously rotating the drum using the pedal. Moisten
the mass in advance in a separate vessel. The humidity of the mass
is suitable if a few drops of water can be squeezed from it when
clenched in the hand.
Usetherestoftherstchargebagasbedding;1litre/user/week.
Therstchargeisablendofpeatandcompostsoil.Theproduct
matchingtherstchargeis BiolanPeatSoil.(seeAccessorieson
pageEN-10)Asrequired,youcanuseBiolanPeatSoilastherst
charge.
2.2 Using the toilet
You can use the Naturum in either a standing or a sitting position.
• withtheseparatingapintheclosedposition,youcanurinate
into the Naturum either standing or sitting, or wash the toilet
bowl using the hand shower. This way the liquid is drained to the
sewer and does not end up in the composting drum
• opentheapanddropthepaperintothecompostingdrumeven
after urination.
• beforesittingfordefecation,opentheseparatingapthatcloses
the drum by turning the operating lever (part 10).
• after use, depress the pedal a few times to transfer the deposit
andthepaperoutofsightandushtheliquidbowlwithasmall
amount of water.
2.3 If the toilet is not used year-round
Installed in a cold space, the toilet can freeze during winter. The
toilet unit is manufactured of frost-proof polyethylene, so freezing
does not damage it. During a period of persistent frost, the compost
mass in the Naturum can freeze and can no longer be turned in the
composting drum. In this case, use of the unit should be temporar-
ily suspended.
As the temperature rises, the mass soon melts and use of the Natu-
rum can be resumed as soon as the mass again collapses on top
of the waste when the drum is rotated. If the liquid is collected in a
tank susceptible to frost, empty the tank in the autumn in order to
avoid damage caused by freezing of the liquid.
2.4 Using the bulking material
Applying suitable bulking material regularly is essential for proper
operation of the toilet. As bulking material we recommend using
Biolan Ground Peat, which is non-fertilised and non-limed peat, or
the granulated Naturum Bulking Material. Do not use Biolan Com-
post and Toilet Bulking Material (or equivalent) in the Naturum, as
it contains coarse bark.
Add bulking material once a week. The amount of Biolan Ground
Peat to be used is one litre per user per week, and the amount of
Naturum Bulking Material is half a litre per week per user. Dose the
bulking material through the seat opening by simultaneously rotat-
ing the drum via the pedal.
Moisten the peat before putting it into the drum. The humidity of the
peat is suitable if, when clenched in the hand, a few drops of water
are squeezed from it. Dry peat repels liquid and does not absorb it.
The Naturum Bulking Material should be added as dry, but if the
compost mass also is dry, it can be moistened.
2.5 Using the service rake
Remove any mass stuck to the edges of the drum through the emp-
tying door, using the service rake. Rotate the drum simultaneously.
During regular use, do this once a week and always after breaks in
operation. If the mass has dried out, add some moist bulking mate-
rial to it while you rotate the drum.
EN
2. Use and maintenance of the
Naturum
Use and maintain the Naturum in accordance with the instructions.
This makes the use and maintenance of the toilet more pleasant.
Whenusingtheunitfortherstfewtimes,verifythatyourownseat-
ing distance and habits are suitable for it. Also instruct your guests
on how the toilet should be used.
The Naturum is intended for composting all types of toilet waste,
including toilet paper.
But do not put into the toilet anything that could hamper post-treat-
ment of the toilet waste, such as:
• debris, sanitary towels
• chemicals, lime
• detergents, washing water
• ash, cigarette butts, matches
1.3 Planning and installing the drainage
system for the toilet
Drain the liquid in a closed tank for later use, treat it together with
other wastewater from the property, or take it to the wastewater
treatment plant. When dimensioning the liquid tank and decid-
ing where to locate it, you need to take into account that the daily
amount of liquid from the separating toilet is 1-1,5 litres per user. In
addition to plain urine, take also into account in dimensioning the
amount of washing water used.
The drain hose is connected to the rear of the unit at 8.5 cm from
theoor.Thedrainhoseisexible,soyoucanmoveitsideways.
Theliquidmustowwithoutobstructionallthewaytothedrain.De-
pending on the installation location, accomplish the lead-through
eitherasasewer,orasapipeleadingthroughthewallortheoor.
The diameter of the toilet unit’s drain hose is 32 mm. Route the liq-
uid forward from the unit through a pipe joined up from sewer pipe
parts of at least 50 cm in diameter. Buy parts for the connections
at the plumbing supply store.
You can use the facility reserved for the sewer pipe of
a WC for draining liquids from the Naturum. The sewer
may be located as recommended/required for a WC.
Connectanangulartting of90degreestoNaturum'
s 32-mm drain hose, connect this to a 32-50 reducer,
and further to a 50-110 reducer.
Typical slurry tanks and closed tanks are the most suitable for
urine. These are available in various sizes and their most common
materialisrotationallymouldedpolyethyleneorglass-bre(polyes-
ter)laminate.A30-litrecanisterlocatedundertheoorisinmost
cases sufcient forsummerhouses, as this is sufciently light to
carry into the forest or to spread its contents on the plants.
In year-round use, 3 cubic metres, i.e. 3000 litres should be consid-
ered as the minimum volume for a family of four. Then the tank that
is used with Naturum must be emptied on average once a year. The
tankshouldbettedwithaØ200mmpipe,whichisextendedby
50-70 cm above the ground surface. The pipe shall be closed with
a threaded cover equipped with a rubber gasket.
It is recommended to branch a ventilation pipe from the pipe routed
into the tank to a place, where the possible smell of urine causes
the least nuisance.
Liquids rich in nutrients must not be allowed to enter
the soil as they cause an excessively concentrated nu-
trient load.

3. What happens in the Naturum,
and how does it work?
Composting of solid waste
A Solid waste drops into the drum through the seat opening.
B The drum is rotated using the pedal in order to cover the fresh
waste with the compost mass and to avoid creating any odour.
C The compost is mixed by rotating the drum.
D The mass gradually drops through the opening in the division
wall into the emptying receptacle.
E The composting process continues in the emptying receptacle
(part 22).
Liquids
F Urine and washing water are separated as "clean" and drained
out of the unit.
Ventilation
G The ventilation pipe is routed to the roof.
Operation of the drum
Thepedal(part18)isxedtothedrawwire(part17),whichturns
the drum around: counter-clockwise viewed from the front. As the
pedal is released, the wire returns to its initial position. The hold
wire (part 16) keeps the drum in position, preventing it from turning
back.Theotherendsof thewiresarexedtothe drawandhold
springs (parts 19, 18).

2.6 Emptying the inner receptacle
Emptytheemptyingreceptacleassoonasitllsup.Theemptying
intervals of the receptacle depend on how frequently the toilet is
being used.
• open the door in the seat
• cover the emptying receptacle with its lid and pull it out
• empty the receptacle for post-composting
• return the receptacle to its place
It is not necessary to wash the emptying receptacle on the inside
every time the receptacle is emptied.
During use, the emptying receptacle stands open without the cover
inside the toilet unit. Keep the lid someplace other than next to the
receptacle as it may end up under the receptacle, and shift the
receptacle into the wrong position. Refer to page EN-11 for instruc-
tions about composting the solid waste from the toilet.
2.7 Emptying the liquid tank
Empty the liquid tank, if necessary. You can have a large tank emp-
tied by means of a gully emptier, a suction tank mounted on a trac-
tor trailer, or by pumping. The emptying intervals are determined by
the size of the liquid tank and by how often the toilet is being used.
One person produces 1-1.5 litres of urine daily. More about the uti-
lisation of urine on page EN-11.
For emptying by pumping, thread a small submersible pump in
through the emptying pipe, and apply the urine-water mixture di-
rectly onto the spreading area. The output of the pump should pref-
erably exceed 500 W so that it could power a sprinkler, for example,
and so that the emptying does not take too long. It pays to empty
the tank when it is raining (however, not in torrential rain). Then you
will get the dilute water "free".
2.8 Cleaning the Naturum
Wash and clean the toilet, as necessary. You can use any commonly
available domestic cleaning agent. Avoid using scrubbing agents
andtools.Youcandismantlethetoiletbowlandtheseparatingap
to enable proper cleaning of the unit.
Wash the liquid bowl and the drain pipe with warm water and mild
detergent, and in addition at least once a year, with crystallised so-
dium to remove any precipitate that has been formed by the urine.
If necessary, clean also the drain trap with water/crystallised so-
dium dilution. You can purchase crystallised sodium, for example,
in building material stores.
2.9 Replacing the draw wire
To change the draw wire, open the front jacket (see point 11.2). One
end of the draw wire is attached to the pedal, and the other end as
shown in Fig. 4. The draw wire goes in the rear groove. Clean the
wire and the groove from greasy dirt with acetone.
2.10 Tightening the draw wire
The other end of the wire is adjustable (Fig. 9), and can be tight-
ened as necessary.

4. Problems that may occur
4.1. Odour
If odour problems occur:
• check that there is no liquid on the bottom of the drum. If there
is some liquid, ensure that all users of the toilet have understood
theoperationandpurposeoftheap.Addbulkingmaterialto
absorb the excess liquid.
• check that the ventilation of the toilet is operational. Natural ven-
tilation: make sure that the ventilation pipe routed from the toilet
unit to the roof, is straight and extends above the roof ridge. If
the ventilation pipe is not straight or does not extend above the
roof ridge, you can repair the installation or improve the ventila-
tion by installing a separate Exhaust Ventilator (see Accessories
on page 6). If the property is equipped with mechanical extract
ventilation, the Naturum is connected to this system (see point
1.2.3).
• any devices that affect the pressure of the inside air, such as a
replaceoraroofor stoveextractfan,mayimpairthenatural
ventilation by causing vacuum inside the Naturum. To avoid this,
ensureasufcientsupplyofreplacementairsothatthereplace-
ment air is never routed via the Naturum.
4.2. Condensed water
If water leaks from the ventilation pipe to the toilet:
• check that the ventilation pipe of the toilet is properly insulated
in the cold space. If the pipe is not insulated, insulate it later,
if necessary. Add dry bulking material into the unit, and mix it
using the service rake. Simultaneously, depress the pedal (part
31).
4.3. Mass is moist
Moist mass hinders the motion of the drum, and the mass may
slide.
• check that the ventilation pipe of the toilet is properly insulated
in the cold space. If the pipe is not insulated, insulate it.
• ensurethatthereisnothingundertheseparatingapthatmight
prevent it from closing properly. Remove and wash the valve as
required.
• ensure that all users of the toilet have understood the operation
andpurposeoftheap.Adddrybulkingmaterialintotheunit,
and mix it using the service rake. Simultaneously, depress the
pedal (part 31).
4.4. The mass slides, i.e. does not move with
the drum
If the mass slides inside the drum, it is too wet.
• see point 4.3
4.5. The mass forms a heap inside the drum
Have you added too much bulking material at one time?
It is normal that, when bulking material is added, the mass heaps
up for a while inside the drum. As required, push the mass down
using the service rake (part 23), and depress the pedal (part 31).
4.6. The mass clods
Ifthemassclodsorisdifculttoturnaround,itistoodry.
• rake the entire compost drum using the service rake (part 23),
and add some moist bulking material.
4.7. The mass does not rise into the emptying
drum
If the mass does not rise into the emptying drum, it is too dry.
• Moisten the mass either by adding water through the seat open-
ing or add some moist bulking material. As necessary, mix the
moist mass with the rest of the mass using the service rake, and
simultaneously depressing the pedal.
4.8 The pedal feels stiff
If the pedal appears stiffer than normally:
• check whether the emptying receptacle is full; if it is, then it
must be emptied
• check that the mass is suitably moist (see point 4.3)
4.9 The pedal feels loose
If the pedal starts to feel loose, and the drum does not rotate:
• open the front jacket. Check whether the draw wire has come
loose from the pedal or is cut off. Reconnect or replace, as nec-
essary.
• Check whether the draw spring on the wire has come loose or is
cut off. Reconnect or replace, as necessary.
• the draw wire is the one in the rear groove, which, viewed from
the front, is attached to the spring on the left-hand side (Fig. 4).
If the wires and the springs are in order, but the pedal does not rise,
or it rises too slowly, the wire has unwound.
• turn the draw wire once around the rear way, clockwise viewed
from the side, and after that reconnect it to the pedal.
4.10 The wires slide
If the wire slides in its groove, and the drum does not rotate prop-
erly.
• Clean the groove from dirt and grease. You can use acetone for
this.Becarefulnottospillitontheglass-breparts.
• If cleaning does not help, remove the heat shrink from the end of
the wire, and tighten the wire (see Fig. 8). The other end of both
wires is adjustable.
4.11 Someliquidleaksontheoor
Anyliquidendingupinthedrummayleakontotheoorfromunder
the jacket at the front edge of the unit:
• check that the drain trap is not blocked. As necessary, clean it
with crystallised sodium and warm water.
• checkthatallusersoftheunithaveunderstoodthesignicance
oftheseparatingap.Addbulkingmaterialtoabsorbtheexcess
liquid.
4.12 Insects
Ifthetoiletunitisinfestedwith,forexample,ies:
• empty the emptying receptacle into a compost and then wash it.
• doawaywithanyyinginsectsinthetoiletspaceusingpyrethrin-
basedspray. Repeatthe treatment dailyuntilyinginsects no
longer can be spotted. Repeat the cure immediately, if insects
reappear in the space
• aside from the spray, also use an insecticide that shall be mixed
with water Make a mixture of half a litre of the insecticide, and
mix it with the mass. The liquid pesticide can also be mixed with
the peat bedding. The treatment shall be repeated once a week
until the insects no longer appear.
• consult your local garden centre to select a suitable pyrethrin-
based product.
• start using granulated Naturum Bulking Material instead of Bio-
lan Peat,
• check that when natural ventilation is applied, the ventilation
pipe is routed from the toilet unit straight to the roof, and that it
extends above the roof ridge. If the ventilation pipe is not straight
or does not extend above the roof ridge, you can repair the instal-
lation or improve the ventilation by installing a separate Exhaust
Ventilator (see Accessories on page EN-10).
Soil dwelling mites are the decomposers in the compost, They very
rarely want to leave the compost. If they run out of nutrition, they
mayleavethecompost,andappearasnelightdustontheoor.
Control with a pyrethrin-based spray insecticide and vacuum out.
The control must be performed several times in series within 2-3
weeks, at intervals of a few days.

5. Post-composting the toilet waste
The compost emptied from the Biolan Naturum is partially mature.
Post-composting is always recommended for the compost. If the
compost is to be used for vegetable plots or for edible plants, post-
compost it for about a year in order to exterminate the microbes in
the compost mass.
You can compost the toilet waste together with garden waste and
domestic bio-waste. While composting, make sure to observe the
localregulationsonwastehandlingandconsidersufcientprotec-
tive distances to neighbours, wells and nearby bodies of water.
Organise the composting so that no liquids seep from the compost
into the soil. The Biolan Garden Composter or the Biolan Biolan
Stone Composter (see Accessories on page EN-10) are suited to
the purpose.
The micro-organisms in the compost decompose organic matter un-
der aerobic conditions. After the composting has continued for 1-3
years, the result will be compost soil. To ensure that the composting
isasefcientaspossible,providethewaste-decomposingmicro-or-
ganisms with favourable living conditions. The basic requirements
for compost are the presence of oxygen, moisture and nutrients.
The micro-organisms in the compost live in a humid environment,
so the compost must be suitably moist. Therefore, dampen the
compost with water or separated urine, which also provides the
compost with a good source of nitrogen supplement. To ensure
thatthecompostissufcientlyairy,usecoarsebulkingmaterialor
branch chaff in layers among the waste. Compost that is too tightly
packed or too wet is anaerobic and starts to rot and smell.
After the addition of toilet waste or liquid, carefully cover the sur-
face of the compost with bulking material, garden waste or peat.
When composting, follow the instructions for the composter that
you are using. Toilet waste, composted with care, makes excellent
soil conditioner for perennial plants, shrubs, trees and a vegetable
plot.

6. Utilisation of liquid
You can use the separated liquid as nitrogen fertiliser as such or
diluted with water, for example, for lawns, ornamental bushes and
perennial plants. In the spring, in connection with the initial fertili-
sation, it can also be used for a vegetable plot. During the growing
season urine should not be applied directly to edible plants. The
recommended storage time for urine is about 2-3 months before
it should be used in the garden. Do not apply urine to plants in the
autumn, in order to avoid disturbing the perennials' preparation
for winter.
Asafedilutionratiois1:5,whichmeansonelitreisdilutedwithve
litres of water.
You can use also undiluted urine, but the area must then be care-
fully watered after the application to avoid early blight. Carry out
the application when it is cloudy, either early in the morning or late
in the evening, when the evaporation of nitrogen and odour-related
problems are at a minimum. During the growing season, you can
apply 1-1,5 l/m² undiluted urine in a kitchen garden.
Please consult your local waste advisor or the secre-
tary for environmental affairs in your municipality for
regulations on composting.
