(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.
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 can-
ister 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 manufac-
tured 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 recepta-
cle 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 ven-
tilation 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, us-
ing 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 con-
centrated nutrient load.
