The following instrucons relate to Figure 1 and are the recommended installaon procedures. This may vary
depending on the locaon.
1. Unpack the unit and remove all contents from the pedestal.
2. Cut a 2” DWV PVC pipe to suit the thickness of your wall leaving sucient length to connect the 2” Tee on the
outside.
3. Insert the 2” DWV PVC pipe into the pedestal venlaon outlet. The Wallace seal for the vent outlet is pre-
greased for ease of inseron of the 50mm vent pipe.
4. Posion the pedestal with the rear against the wall.
5. Mark the venlaon and drain outlet posions on the wall.
6. Put the pedestal aside and drill through the wall for the drain pipe and venlaon pipe respecvely.
NOTE:The drain pipe exit hole must be lower than the pedestal outlet.
7. Connect the drain hose to the pedestal using the hose barb and hose clamp.
8. Return the pedestal to the wall. Place the 50mm oor ange supplied in the hole drilled in the wall for the vent
pipe. This gives it a dy appearance. Feed the drain and vent pipe out through the wall. Using the mounng
blocks provided, x the pedestal to the wall by screwing through the rear wall of the pedestal and through the
mounng blocks into the wall. At least 2 xing points should be installed at a minimum of 100mm apart.
9. Proceed to exterior piping installaon. Connect the 2” Tee, 2” Cap and 4” to 2” Eccentric Reducer (including
12V DC fan) as shown in Figure 1 or Figure 2. Addional pipe may be required. Refer to Secon 2.4.
NOTE: Do not glue the Eccentric Reducer to the 4” 45° Elbow or 2” Tee to the 2” DWV pipe.
This allows for removal of the fan should it require replacement.
2.4 Venlaon Pipe
Air ow through the system is essenal to the operaon of the unit and care must be taken to ensure that the vent
line is installed correctly. The Venlaon system is used to help the composng process and to prevent odours from
escaping into the toilet room
Due to the variety of possible conguraons, the vent kit supplied with your CM2 only includes the essenal
components. Addional DWV pipe and ngs may be required for a complete installaon.
The venlaon must be installed in accordance with AS 3500 Clause 6.7.4 where the pipe terminaon must be as
follows;
• 150mm above point of roof penetraon.
• 600mm above any building opening that is within a horizontal distance of 3 meters.
• 600mm above any eave that is within 600mm from the vent.
The venlaon piping must be installed with a minimum grade of 1.25% sloping away from the pedestal and should be
as short as possible.

2.0 INSTALLATION
2.5 Venlaon Fan
If no 240v power socket is available, the fan can be connected to alternave power sources such as a solar power
system. Solar kits are available from Clivus Multrum. The fans are rated for voltages between 8 and 15 V DC.
2.6 Passive Ventilation Option
A passive vent system is where no electric fan is used and air ow is induced by the use of a turbo vent and the vent
“chimney eect”.
A passive vent system can be installed however a connuous odour free system cannot be guaranteed. This opon is
only used where the locaon is remote and no power source is available.
If installing passive vent system the following is recommended:
1. Remove the electric fan to ensure unrestricted air ow.
2. Increase the vent diameter to 4” DWV PVC as soon as possible aer the exit from the pedestal.
3. If possible locate the vent on the Northern side of the building in direct sunlight and paint the vent
black.
4. Install a 100mm turbo vent on top of the vent stack to draw air when there is wind blowing outside.
The turbo vent and associated ngs can be purchased from Clivus Multrum.
2.7 Signage
Your CM2 comes with an embossed logo and model number on the top of the unit. The serial number can be located
on the back of the unit. Further details such as Clivus Multrum contact details, design capacity, operang condion,
electrical requirement and basic noce and instrucons are located in the front page of this manual.

2.8 Excess Liquid Drain Installaon
The drainage system to be chosen depends enrely on the soil condion, ground water level, and local regulaon. Two
drainage opons for CM2 are recommended as below:
2.8.1 Opon I—Absorpon Trench
This is the normal method for disposal of excess liquid, but refer to council for permit for any specic
requirements. These instrucons apply to installaon of the drain kit items available from Clivus Multrum.
1. Dig a trench in a posion located in front of the liquid end product drain.
2. The trench is to be located in soil of good permeability and in a posion 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 ngs will also drain to 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 locaons it may be desirable or necessary to connect the excess liquid drain to a grey water
system or an alternave disposal method complying with AS/NZS 1547:2012.
Trench dimensions and construcon are to be in accordance with AS/NZS 1547:2012, as shown in Figure 5.
Figure 5: Durable self supporng arch trench
Dimensions in mm.
It is important to ensure that the trench is level along its length. Ensure the liquid drain
pipe slopes away from the toilet. Trench should be protected from surface water and
ooding, and vehicle trac.
2.8.2 Opon II—25 Litre Translucent Container
This opon is for installaon with high ground water level, poor permeability or rocks.
Figure 6: Translucent Container 25 Litre Capacity
Excess liquid can be drained into the container. When lled, remove and dilute 1 to 4 with water and use as ferliser.

3.1 Inial Setup
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 venlaon fan to power socket.
4. Add 5 litres of Wood Shavings into the composng chamber.
5. CM2 is ready to be used!
4.1 General Care
The CM2 should be examined regularly to ensure correct operaon. The key areas to be checked are listed below:
• Check venlaon fan is running.
• Check there is no access liquid in the compost chamber and pedestal. Refer to Secon 7.0 for troubleshoong.
4.2 Removing The Chamber
The acve 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 li the chamber out from the pedestal. When liing the chamber, please be
aware that there may be liquid dripping o from the chamber oor holes.
3. Place the chamber outside for secondary composng. The chamber should be placed in a warm sunny posion
preferably in warm area such as directly under the sunlight and where direct access is restricted.
4. Put the empty second chamber in the pedestal. Remove the chamber lid and keep it in a safe place.
5. Add Wod Shavings.
6. Put back the pedestal lid.
7. CM2 is ready to be used again.
4.3 When Do I Empty The Secondary Chamber?
As a general rule, you should leave the material in the compost chamber as long as possible. The CM2 has been
designed for 2 people full me where the average monthly temperature is greater than 18° C in any given month.
Under these condions the full chamber should only require a maximum of 60 days before it is ready for emptying.
Compost temperature is a signicant factor in the me required for composng process. The higher the temperature
within the opmum range, the faster the compost process. As a reference, 50 days is required to reach 50%
decomposion with a compost temperature ranging between 22-24°C.

3.0 USING THE CM2
4.0 MAINTENANCE

OM-CM2.201104 Updated: 04/11/2018 Page 10 of 13
Copyright © Ecoo Wastewater Management
When ready for disposal the composted end product should not contain recognizable faecal material and there should
be no oensive odours immediately aer removing the chamber lid.
If there is more than 2 people using the toilet or you are in a colder area then addional compost chambers may be
required. Addional compost chambers can be purchased from Clivus Multrum.
4.4 How Do I Dispose The Composted End Product?
Clivus Multrum recommends wearing protecve clothing whenever handling waste products. Recommended
protecve clothing includes gloves, appropriate footwear, a face mask and ideally eye protecon.
You should dispose of the composted waste in accordance with any and all local authority regulaons. All composted
product should be handled and treated with cauon as there is a risk of exposure to pathogens parcularly if the
product is not properly composted.
For an on-site burial of composted end product, it should be undertaken in a locaon where direct access by human
and animals are restricted. It should be buried with a minimum cover of 100mm in soil that is not intended to be used
for the culvaon of root vegetables or near a water catchment area.
4.5 Adding Bulking 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 me.
In me of heavy use, or if the liquid is not draining well through the compost, or if compost appears too dry, we
suggest you mix the addional Wood Shavings through the compost pile.
By mixing the solid waste, paper and bulking material, the compost will be kept porous and moist, the supply of
oxygen will increase, which substanally speeds up the transformaon of waste materials into humus.
Bulking material: Untreated wood shavings or other carbon rich material. (Sawdust is not recommended)
4.6 Insects
If insects have entered into your compost, you should sprinkle an insect control powder or any other long lasng
pyrethrum based product over the compost chamber.
4.7 Cleaning
Use mild detergents on your CM2. Never use scouring powder or other strong detergents that could scratch the
surface, or kill o your good bacteria. We recommend green friendly or sepc safe products.
4.8 Warning
Never put cigarees or other burning material, tampons or sanitary napkins into your toilet!

OM-CM2.201104 Updated: 04/11/2018 Page 11 of 13

5.1 General
Composng involves the biological decomposion of organic maer using natural occurring organisms such as
bacteria, fungi and other small organisms into compost which is a humus-like product.
The composng process can be aerobic or anaerobic however aerobic decomposion is desirable because it is
ecient and does not produce unpleasant odours. Composng in a Clivus is eecvely aerobic however there may be
anaerobic decomposion within small pockets within the compost pile.
The composng process involves four main components: microbes ( including bacteria, fungi and protozoa), organic
maer, 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 using the oxygen present. As the carbon dioxide and water vapor is released into the
environment the pile becomes smaller.
Nitrogen is also a crucial element in the composng process which is required by the microbes for cell growth. For
opmal decomposion the rao of carbon to Nitrogen should be around 30:1. Urine and human feces are relavely
high in Nitrogen and therefore addional carbon is required for opmal composng.
5.2 Moisture
In opmum condions, the compost material has consistency of pong mix about 35% to 65% moisture.
When below 35%, there is not sucient moisture for the microorganisms to funcon and above 70% saturated
condions begin to develop and oxygen depleon becomes a liming factor. Under these condion the process
becomes anaerobic and the process releases odorous gases such as methane and hydrogen sulphide.
5.3 Temperature
The opmum 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 me to compost.
Addional chambers may be required in this instance.
5.4 Aeraon
The aerobic organisms responsible for the composng process require air to survive.
Without air, they will die and be replaced by anaerobic micro organisms that will slow the composng process and
generate odour.
For compost toilets to work most eecvely, the material being composted should be unsaturated with liquids, and
have a loose texture to allow air to circulate freely within the pile.
5.5 Pathogens
Pathogens are eliminated through the long retenon mes in the compost, the compost temperature and the acvity
of the micro-organisms.
5.0 HOW COMPOSTING WORKS

OM-CM2.201104 Updated: 04/11/2018 Page 12 of 13
Copyright © Ecoo Wastewater Management
A. Why is the compost chamber lling too quickly?
This can be caused by ineecve composng process due to numbers of issue listed below:
Compost pile being too wet—This means liquid is trapped in the compost chamber contribung to quick
volume built 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 evaporaon process will be slowed and odours start to
escape into the toilet room. This can be caused by a malfunconing fan or venlaon system has been blocked.
Check if fan is properly connected or replace the fan if broken. Check if the insect neng has been block.
B. Why is the composng process slow to complete?
Composng process is dependent on temperature and humidity. Listed below are factors that could slow down
the process:
Compost pile being too wet—The addion of wood shavings is an imperave part of the operaon of a
composng toilet. Wood shavings will assist with the absorpon of liquid in your composng toilet and will aid
in improving the carbon/nitrogen rao (important for composng) and will allow air to ow more freely
through the system as it loosens the compost pile.

7.0 TROUBLESHOOTING

OM-CM2.201104 Updated: 04/11/2018 Page 13 of 13
Copyright © Ecoo Wastewater Management
Compost pile surrounding temperature is 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 low simply turn it up slightly to increase airow.
When taking the compost chamber out for secondary composng, make sure it is located in a warm spot
preferably in direct sunlight.
C. How to deal with insects aracted to compost pile?
Insect Control—To break the breeding cycle of insects (most commonly, vinegar ies) spray the compost pile
with pyrethrum based insect spray for 7 consecuve days. Always place a layer of wood shavings over the top
of the pile in the out of service chamber to eliminate the possibility of insects laying eggs.
