PREPARATION & BUILDING DESIGN Cont...
Structural Issues
The Rota-Loo is installed sub-floor. It may be installed under a concrete slab or bearer and joist floor,
in a full or partial cellar as desired in the building design. Consider the spacing of joists or concrete slab
penetrations to allow for the waste chute. Consult a relevant Engineer to ensure support spacing and floor
spans are adequate for the size and position of the Rota-Loo.
Most Rota-Loos are installed in a location largely protected
from the elements and can sit freely on the base. If your
installation is likely to experience extremes, you may need
to consider anchoring the Rota-Loo to the ground to prevent it moving in the event of weather events.
Rota-Loo is not designed to be fully immersed in water so should not be installed where severe flooding
may occur without flood protection.
Vent System
The Rota-Loo airflow requirement is provided by DWV piping (not supplied) from an inlet filter
(supplied) to a Turbo Vent (supplied) and incorporates a continuous running fan (supplied).
• The Rota-Loo 2000 comes with 2 Pods for the vent piping. These may be placed as suits the
installation. The Inlet needs to be fitted low and opposite the Outlet, which will be higher.
•
The fan is to be fitted on the outlet side. Consider how the fan will be powered (240VAC or 12VDC)
and ensure the fan housing is accessible for maintenance.
• The air inlet (inlet Filter) needs to be located lower than the Pedestal, otherwise you will draw air
from the toilet cubicle rather than where the air inlet is located. (To draw warm air down from ceiling
cavities typically requires a second fan)
•
Remember that warm air naturally rises and that sharp bends restrict airflow - designing the vent
piping correctly will improve natural operation.
• Warm air holding moisture entering cold air can result in condensation. Consider insulating the outlet
vent piping, and ensuring you install the supplied condensate trap, particularly in cold climates.
Excess Liquid
Under normal conditions, all liquids should be dealt with by normal evaporation. If the installation
experiences excessive use or does not get enough heat to evaporate the liquid internally, it may be
necessary to plan to install a secondary system to handle the excess liquid. This may be a secondary
evaporating tank, which should be installed in a sunny location, or an Absorption Trench System.
Speak to your supplier or Rota-Loo for advice if you think this may be needed.
AS 1546.2 requires that access to a WCT be
prevented from unauthorised people. Consider
whether your installation needs access restriction
methods to prevent young children or vandals
from access.

Hot air
If a 240VAC fan is to be
installed, a standard single
GPO needs to be provided
close to the fan position and
installed according to AS/NZ
3500 & AS/NZ 3820.
If solar power is planned,
consult a solar installer to
provide a system that will
keep the fan running 24/7
- the 12 DVC fan power
consumption is 3.0W
