If installing the toilet in a warm space indoors, insulate the ven-
tilation pipe of the toilet where it runs through cold spaces, for
example, in the intermediate roof space, to prevent condensation
of water.
If you have to make some bends, take note that the curvature
of such bends must not exceed 33 degrees. You can boost the
ventilation and evaporation of moisture by means of the optional
Biolan Wind Fan (see Accessories on page EN-8). In complicated
installations or when installing the Composting Toilet Biolan
eco
in a
residential location, it is recommended to use an additional Biolan
Exhaust Ventilator, which can be installed in the ventilation pipe
(see Accessories on page EN-8). As required, you can even retro-
ttheventilator.
Where necessary, the ventilation pipe can be extended using the
ordinary grey sewage pipes and ttings (diameter 75 mm). You
can purchase ventilation pipes (part 13) also as spare parts from
the Biolan web shop or ask your dealer to order these for you.
1.6 Leading off the seep liquid
The liquid separator plate at the bottom of the Composting Toilet
Biolan
eco
enables separation of excess liquid – the seep liquid –
from the compost mass. This plate is removable, so you can take
it away for cleaning, as required. Place the plate into the recess in
the bottom of the Composting Toilet Biolan
eco
.
Connect the seep liquid pipe to the drain hole in one side of the
toilet unit. Route the pipe into a canister. Bury the canister in the
ground,orplaceitsomeotherwaysothattheseepliquidows
by gravitation into the canister. Keep in mind possible use of the
toilet in winter when laying the seep liquid pipe and locating and
insulating the canister.
Where necessary, the ventilation pipe can be extended using sew-
agepipesandttings(75mmindiameter).Youcanpurchaseliq-
uid pipe also as a spare part from the Biolan web shop at www.bio-
lan.oraskyourdealertoorderthisforyou.Alwaysusesleeves
with a sealing ring for joining up the pipes.
Route the hose into a canister that you have placed in such a way
thattheliquidwillowbygravityalone.Ifyouwant,youcanbuild
anexternallyinsulatedpitwithacoveroflm-facedplywood(as
showninFigure1onpage5).Iftheseepliquidcanisterisdifcult
to bury in the ground, you can replace it with a smaller canister or
an evaporating pan. The evaporating pan must be provided with
an overhead rain lid – non-fertilised Biolan Peat is recommended
for neutralisation of odours (see Accessories on page EN-8). If you
want, you can lay the canister on its side.
The amount of seep liquid from the Composting Toilet Biolan
eco
is
small, depending on the use, about 0.2 to 0.5 litres/user/per day.
The seep liquid, however, is extremely rich in nutrients and must
notbeallowedtoentersoilwithoutbeingtreatedrst.
Liquids rich in nutrients must not be allowed to enter
the soil as they cause an excessively concentrated
nutrient load.
2. Use and maintenance of the
Composting Toilet Biolan
eco
Proper use of the Composting Toilet Biolan
eco
allowsmoreefcient
composting of the mass, and enables more convenient use and
emptying of the composter. Thanks to the thermal insulation of the
toilet,compostingofthewasteisefcientandthusthecapacityof
the toilet unit is increased as the waste is greatly compressed as a
result of decomposition.
The composting process starts as soon as there is a sufcient
amount of waste in the composter, i.e. normally the unit is half-full
of waste. The composting process is understood to start when the
temperature of the mass inside the toilet rises above the outside
air temperature. The temperature is raised and maintained by the
vital functions of the micro-organisms that are created in the com-
poster provided that waste is added regularly. After start-up, the
waste reaches the cover soil stage in 6-7 weeks.
The amount of seep liquid created is greatest at the start, but is
reduced as a result of warming up of the compost mass and evap-
oration.
2.1 Before putting the Composting
Toilet Biolan
eco
to use
Make sure that the air channel (part 8) inside the compost tank
is still in place after transportation. The channel must rest on the
sill on the inside wall of the tank so that the inlet air valve (part 5)
abovetheemptyingdoorwillallowunobstructedairowintotheair
channel. The air inlet valve cannot be adjusted.
Put a layer approximately 5 cm thick (about 20 l) of Biolan Com-
post and Toilet Bulking Material (see Accessories on page EN-8)
on the bottom of the Composting Toilet Biolan
eco
to prevent the
liquid separator plate (part 7) from getting blocked.
2.2 Adjusting the replacement air
valve in the seat top
Ventilation of the toilet is controlled by means of the replacement
air valve (part 12) in the seat top.
Keep the replacement air valve open during summer to ensure the
ventilationremainsefcientandtheevaporation of liquids inten-
sive. Keep the replacement air valve almost closed during winter
to reduce heat loss from the compost. When the toilet is not in use,
keep the seat lid closed to ensure correct operation of the
ventilation.
2.3 Air channel in the toilet tank
Operation of the Composting Toilet Biolan
eco
is very effective be-
cause of the air channel (part 8) inside the toilet unit. The channel
brings the air required by the compost to the centre of the com-
post mass – to the layer where it is most needed. At the same
time, the air channel prevents the compost mass from packing on
the bottom and keeps the mass elevated during emptying. The
air channel is visible at the initial stage, but after that, it is virtually
obscured by the mass all the time.
2.3.1 Adjusting the inlet air valve above the
emptying door
The inlet air valve above the emptying door (parts 4 and 5) cannot
be adjusted. Its purpose is to bring air into the air channel (part 8).
See point 2.3.
