A 12V DC transformer is supplied with
your system which can plug directly
into a 240V power point (GPO). The
transformer needs to be located under
cover. The power leads from the 12V
transformer must be connected to the
fan in the housing.
If no 240v power socket is available,
the fan can be connected to alternative
power sources such as a solar power
system. Solar kits are available from
Ecoo. The fans are rated for voltages
between 8 and 12V DC.

The drainage system to be chosen depends entirely on the soil condition, ground water level,
and local regulation. Please ensure you choose your location with this in mind.
EXCESS LIQUID DRAIN INSTALLATION
This is the normal method for disposal of excess liquid, but refer to council for permit for any
specic requirements. These instructions apply to installation of the drain kit items available
from Ecoo.
1. Dig a trench in a position located in front of the liquid end product drain.
2. The trench is to be located in soil of good permeability and in a position where
ground water will not ood the unit.
3. If there is some doubt as to the permeability of soil, extra trenching length may
be required especially if a hand basin or other ttings will also drain into the same
trench.
4. The liquid leaving the compost unit when in use is not expected to exceed 1 litre per
day per resident.
5. In some locations it may be desirable or necessary to connect the excess liquid drain
to a grey water system or an alternative disposal method complying with AS/NZS
1547:2012.
Trench dimensions and construction are to be in accordance with AS/NZS 1547:2012, as
shown in Figure 5.

Absorption Trench
It is important to ensure that the trench
is level along its length. Ensure the liquid
drain pipe slopes away from the toilet and
towards the trench. The trench should be
protected from surface water, and ooding,
and vehicle trac.

USING THE NL2
1. Once the pedestal has been installed, place one compost chamber inside the
pedestal.
2. Remove the chamber lid and put back the pedestal lid. Do not misplace the chamber
lid and make sure it is kept somewhere safe.
3. Connect the power outlet for the ventilation fan to power source.
4. Add 5 litres of bulking agent into the composting chamber.
5. CNL2 is ready to be used!
INITIAL SETUP
MAINTENANCE
The NL2 should be examined regularly to ensure correct operation. The key areas to be
checked are listed below:
• Check ventilation fan is running.
• Check there is no excess liquid in the compost chamber and pedestal. Refer to Section 7.0
for troubleshooting.
GENERAL CARE
The active compost chamber should be replaced with an empty one when it is approximately
75% full or when the pile is approximately 200 mm from top of the toilet seat.
1. Remove the pedestal lid and place the chamber lid on.
2. Swing the handle upright and lift the chamber out from the pedestal. When lifting the
chamber, please be cautious incase of dropletsfrom the chamber oor holes.
3. Place the chamber outside for secondary composting. The chamber should be placed
in a warm sunny position (where direct access is restricted).
4. Put the empty second chamber into the pedestal. Remove the chamber lid and keep
it in a safe place.
5. Add bulkng agent and microbes.
6. Replace the pedestal lid.
7. NL2 is ready to be used again.
REMOVING THE CHAMBER
As a general rule, you should leave the material in the compost chamber as long as possible.
The NL2 has been designed for 2 people full time where the average monthly temperature is
greater than 18° C in any given month.
Compost temperature is a signicant factor in the time required for the composting process.
The higher the temperature (within the optimum range), the faster the compost process.
As a reference, 50 days is required to reach 50% (hald life) decomposition with a compost
temperature ranging between 22-24°C.
WHEN DO I EMPTY THE SECONDARY CHAMBER

14
Ecoo WM recommends wearing protective clothing whenever handling waste products.
Recommended protective clothing includes gloves, appropriate footwear, a face mask and
ideally eye protection.
You should dispose of the composted waste in accordance with any and all local authority
regulations. All composted product should be handled and treated with caution as there is a
risk of exposure to pathogens particularly if the product is not properly composted.
For an on-site burial of composted end product, it should be undertaken in a location where
direct access by humans and animals is restricted. It should be buried with a minimum cover
of 100mm within soil that is not intended for the cultivation of root vegetables or nearby a
water catchment area.
HOW DO I DISPOSE THE COMPOSTED MATERIAL?
It is important to place bulking material into your toilet, we suggest 1 cup per day directly
into the compost chamber. This amount is based on two people using the system full time.
In times of heavy use, if the liquid is not draining well through the compost or if the compost
appears too dry, we suggest mixing the additional bulking agent through the compost pile.
By mixing the solid waste, paper and bulking material, the compost will be kept porous
and moist and the supply of oxygen will increase, which substantially speeds up the
transformation of waste materials into humus.
Bulking material: Hemp, wood shavings or other carbon rich brous material. (Sawdust is not
recommended)
ADDING BULKING MATERIAL
Use mild detergents on your NL2. Never use scouring powder or other strong detergents that
could scratch the surface, or kill o your good bacteria. We recommend green friendly or
septic safe products.
CLEANING
Never put cigarettes or other burning meterial, or any sanitary products into your toilet.
WARNING
When ready for disposal the composted materials should have no oensive odours
immediately after removing the chamber lid (at this stage this should resemble regular
potting mix).
If there is more than 2 people using the toilet or you are in a colder area then additional
compost chambers may be required. Additional compost chambers can be purchased from
Ecoo WM.

HOW COMPOSTING WORKS
Composting involves the biological decomposition of organic matter using natural occurring
organisms such as bacteria, fungi and other micro-organisms into compost which is a humus-
like product.
The composting process can be aerobic or anaerobic however aerobic decomposition is
desirable because it is ecient and does not produce unpleasant odours. Composting in a
Clivus is eectively aerobic however there may be anaerobic decomposition within small
pockets within the compost pile.
The composting process involves four main components: microbes ( including bacteria, fungi
and protozoa), organic matter, water and oxygen. The carbon compounds present in the
organic materials are used by the microorganisms as an energy source and transformed into
carbon dioxide. As the carbon dioxide and water vapor is released into the environment the
compost pile becomes smaller.
Nitrogen is also a crucial element in the composting process which is required by the
microbes for cell growth. For optimal decomposition the ratio of carbon to Nitrogen should be
around 30:1. Urine and human feces are relatively high in Nitrogen and therefore additional
carbon is required for optimal composting.
GENERAL
In optimum conditions, the compost material has the consistency of potting mix with
approximately 35% to 65% moisture content.
When below 35%, there is not sucient moisture for the microorganisms to function
and when above 70%, saturated conditions begin to develop and a lack of oxygen supply
becomes a limiting factor. Under these condition the process becomes anaerobic and odorous
gases such as methane and hydrogen sulphide are released.
MOISTURE
The optimum temperature range for most compost toilets is 18°C to 45°C.
Lower temperatures result in a mouldering process that takes a signicantly longer period of
time to compost. Additional chambers may be required in this instance.
TEMPERATURE
The aerobic organisms responsible for the composting process require oxygen to survive.
Without oxygen, they will die and be replaced by anaerobic micro organisms that will slow the
composting process and generate odour. For compost toilets to work eectively, the material
being composted should be unsaturated, and have a loose texture to allow air to circulate
freely within the pile.
AERATION

16
Pathogens are eliminated through the long retention time within the compost, the
temperature of the compost and the activity of the micro-organisms.

TROUBLESHOOTING
This can be caused by ineective composting processes due to a number of issues as listed
below:
Compost pile being too wet—This means liquid is trapped in the compost chamber
contributing to build-up. Check if the drainage outlet is being blocked. If drainage outlet is
ok, this could be caused by prohibited solids blocking the perforated holes in the oor of the
compost chamber.
Insucient air ow—Without sucient air ow, the evaporation process will be slowed and
odours may start to escape into the toilet room. This can be caused by a malfunctioning fan
or ventilation system has been blocked. Check if fan is properly connected or replace the fan
if broken. Check if the insect netting has been blocked.
WHY IS THE COMPOST CHAMBER FILLING TOO QUICKLY?

17
WHY IS THE COMPOSTING PROCESS SLOW TO COMPLETE?
Composting process is dependent on temperature and humidity.
1. Is your compost pile too wet? The addition of bulking agent is an imperative part of
the operation of a composting toilet. Bulking agent will assist with the absorption of liquid
in your composting toilet and will aid in improving the carbon/nitrogen ratio (important
for composting) and will allow air to ow more freely through the system as it loosens the
compost pile.
2. Is your compost pile surrounding temperature too low? In cool climates do not
insulate the toilet; turn down the fan voltage to lessen cool air being drawn into the
system. If odour occurs due to the fan voltage being turned down, simply turn it up
slightly to increase airow.
When taking the compost chamber out for secondary composting, make sure it is located
in a warm spot preferably in direct sunlight.
3. How to deal with insects attracted to compost pile? To break the breeding cycle
of insects (most commonly, vinegar ies) spray the compost pile with pyrethrum based
insect spray for 7 consecutive days (ensure the fan is turned o while spraying). Always
place a layer of bulking agent over the top of the pile in the out of service chamber to
eliminate the possibility of insects laying eggs.
