INSTALLATION
Step 1: Positioning the Pedestal Diagram
Locate the approximate area where you want the pedestal to go before cutting the hole.
The usual position for pedestals is centred between side walls.
(Please note—due to the pedestals being man made the distance to the centre may vary
from 245—255mm. Please check before cutting the hole).
IMCM-203.07.09.2020 © Ecoflo Wastewater Management Pty Ltd Page 6

emitting from the chamber.) Remove the adhesive cover and place the brush seal on the inside
surface of the lid as shown below.
• Add 50mm depth of bulking agent (supplied) to the chamber to create a bed.
• Slide the ‘In-service’ compost chamber lid (with Pre-Cut Hole) up onto the waste chute from
underneath and place the chamber underneath the lid.
• Lower the lid onto the chamber.
• Rotate the lid to lock the catch plates onto the pins.
• Attach the toggle latches as shown below and the chamber is installed.
Place brush seal on inside surface of
chute extrusion as shown.

Step 7: Connecting the Vent Pipe and Fan to the ‘In-service’ Chamber
The fan runs 24 hours a day to continuously
circulate air through the compost heap. Air
is drawn down the toilet pedestal through
the compost chamber and out the vent pipe.
Fan & Vent pipe Installation Details
The fan is IP68 rated so will not be effected by moisture. Do not glue the fan hous-
ing to the DWV fittings.

POWERING YOUR FAN
Mains Power
A 240/12 volt regulated transformer is included to run the fan from mains power. Connect the
fans to the transformer as follows: The positive wire on the transformer is marked with a white
line. The fan has anti polarity protection and won’t run if connected incorrectly.
We recommend a spare fan is kept on hand at all
times, particularly after a year of use.
Go to Ecoflo Online Store or call 1300 138 182 for
replacement or spare fans.
Solar Power – refer to Solar Panel Installation Manual
EXCESS LIQUID ABSORPTION TRENCH
An Absorption Trench Kit is available – Please see Appendix 1.
Alternatively; If your council allows, you may wish to construct your own Absorption Trench. The Liquid Drain
Hose should run into either a length of 50mm PVC pipe; drilled to allow liquid to escape, OR a length of slotted
Ag pipe buried in the absorption trench as shown in the diagram. Both chambers should be connected.

COMPOSTING ACCELERATORS
Whilst Clivue Multrum users report successful composting without the use of any addi-
tives, we strongly recommend the use of the following in order to optimise composting,
particularly when the toilet is in permanent use by more than two people.
Bulking Agent
Should be added on a regular basis, preferably a handful after each solid
use. Alternatively, if this is not possible add the equivalent of this on a daily
or weekly basis. The bulking agent can be added through the pedestal.
We Do Not recommend the use of :
• sawdust as it creates an anaerobic condition within the chamber.
• Cypress, cedar or eucalypt wood shavings due to their antimicrobial properties.
• Sugar cane mulch as it makes using the mixer difficult.
Nature Flush Enzymes
A 125ml bottle of enzyme concentrate is supplied with the toilet. Please
refer to the label for instructions and spray into the waste chute. A spray
flask is provided. Any staining of the pedestal can also be removed with
the spray.
Nature Quick Microbes
Should be used each time a chamber is changed to kick start the
process in the new chamber.
Contact Ecoflo for further supplies when required.

CARE & MAINTENANCE
Daily or Weekly
• Clean restroom & toilet fixtures using only biodegradable cleaners.
• Add 1 cup of bulking agent to toilet after every solid use.
• Turn the Compost Mixer backwards and forwards once a week; or possibly more often.
Please read “Compost Mixer” section where for benefits.
Check Ecoflo Online Store for Consumables.
Note:
Do not force the compost mixer too much. If it is hard to turn add water to the compost pile
via the waste chute (approx. 2-4L) and turn the mixer back and forth until it frees up.
Monthly
• Inspect the ‘In-service’ chamber, depends on usage, prepare another ‘In-service’ chamber
for use once the chamber becomes full (refer to Rotation of Chambers).
• Check vent pipe & remove any foreign matter.
• Check the fan is operating
• Check that system is draining correctly.
6 months
• Remove & Clean fan

ROTATION OF CHAMBERS
• Your first rotation of the chambers
It is important to observe safety procedures when dealing with
fresh human waste. Please ensure you wear protective clothing
(gloves and old clothes). Do not attempt to move the chambers on
your own.
The Clivus Multrum composting toilet chambers will need to be changed on a regular basis. A suf-
ficient number of chambers must be purchased to allow the ‘Out-of-service’ chamber a minimum
5 months; depending on climate, from the time they are disconnected from the waste chute.
1. Prepare a new ‘In-service’ chamber for use (refer to Step 6: Installing the Compost Chamber).
2. Pour a small bucket of bulking agent (clean mulch) down the pedestal to cover up the waste
pile before removing the full chamber.
• Extra Chamber/s
The ‘Out of Service chamber should be put in a warm position with the Air Intake Cap at-
tached to threaded connector and the dust plug attached to the camlock.
• Removal of Compost
The pile should have reduced in size to approximately 20% of its original size and contain a
maximum of 75% moisture. This ‘humus’ must then be disposed of as per the local health
department regulations. This normally means digging the humus into the soil and covering
with at least 100mm of soil.
• Returning a Chamber to Service
1. Ensure all hose and vent connections are clear.
2. Prepare the ‘In-service’ chamber for use (refer to Step 6: Installing the Compost
Chamber).
If the ‘Out-of-service’ chamber is to be placed away from the Main Vent assembly, you will
need to dig a small second trench (20 x 20 x 20cms) to allow residual liquid to exit the cham-
ber. Connect the second liquid drain hose from the chamber to the trench and turn the valve
to the open position.

TROUBLE SHOOTING
Please read this section before using your toilet.
Find more Trouble Shooting and FAQ information online at ecoflo.com.au/FAQ, or call
us on 1300 138 182.
Clivus Multrum toilets have proven themselves to be one of the easiest systems to manage. However, be-
ing a natural process, reliant on a number of factors beyond our control, it can occasionally need some help
to maintain an appropriate balance.
The ‘In-service’ chamber is filling too quickly:
This may be caused by a number of factors:
The temperature is too low for effective composting.
Insufficient air flow. ‘
This can be caused by a broken fan or the chamber being too full. Check the fan is operating and the
level of the pile is not too high. This problem could also be caused by a blocked insect screen in the
vent cowl.
The pile being too wet.
This could be the result of the outlet of the liquid chamber being blocked and causing the upper
chamber to flood. (This would also cause the fan to malfunction). Check the drain hose is not
blocked and flush with a hose if necessary. You may need to change chambers if the blockage
is in the chamber and thoroughly flush out the contents of the liquid chamber.
Antibiotics and disinfectants will slow down or stop the process. Restart the composting by
reintroducing microorganisms. In many of these situations Nature Flush Enzymes will help
solve inefficient composting by breaking down the solids and thereby speeding up decomposi-
tion.
The ‘Out-of-service’ chamber is composting too slowly:
This may happen due to one or more of the problems described above. At this point the most effec-
tive course of action is to aerate the pile by turning it over with the Compost Mixer. You could also
add 500ml of Nature Flush Enzymes from a domestic spray bottle as you turn the material and add a
quantity of Nature Quick Microbes.
You should consider locating the chamber where it has a greater exposure to direct sun light. Howev-
er, if you find the pile is drying out too quickly put the chamber in a shadier position.
If you find none of the above measures are effective, it means the local climatic conditions are less
than ideal. This can happen in cold or humid conditions and you will need to purchase an additional
chamber in order to provide an extended composting period.
If you need to change your ‘In-service’ chamber and the ‘Out-of-service’ chamber is not yet compost-
ed, dispose of the waste as normal and order an extra chamber from Ecoflo.

The odour from the ‘Out-of-service’ chamber is unpleasant:
If the ‘Out-of-service’ chamber is not connected to the vent pipe it may smell immediately after
it has been taken ‘Out-of-service’. Odours can be greatly reduced or eliminated by covering the
top of the pile with straw or dry grass clippings. You may wish to do this before disconnecting
the chamber.
The odour from the ‘In-service’ chamber is unpleasant:
If this is not caused by a failed fan, blockage in the vent pipe, liquid drain hose or Fitting. Please
see the “‘In-service’ chamber is filling too quickly” section for how to resolve this problem.
The power has failed resulting in toilet room odours:
Cover the pedestal with cling film until the power is restored. If you are connected to mains pow-
er consider installing an Uninterrupted Power Supply (UPS) Available at Ecoflo Wastewater
Management. The UPS will cut in with power from a 7ah battery when there is a loss of mains
power.
Helpful Hints from our customers :
• Paint the Vent Stack black to produce an upward air flow.
• Add a wind assisted turbo vent to the Vent Stack.
Mixer not turning
Do not force the mixer to turn if it is hard. Firstly add water to the compost pile (say 2-4L) and
leave for an hour. Then attempt to rotate the mixer back and forth until it frees up.
In the event you have forced the rotation of the mixer, you may bend the blade, which has been
designed to do this to avoid breaking the gears.
If the blades are bent, they can simply be straightened when the chamber is changed over.

APPENDIX 1 INSTALLING EVERTRENCH LINERS FOR SULLAGE - WASTE WATER DISPOSAL AS/NZS 1547:2012 provides basic information for the design and construction of many on-site waste-water disposal systems. This manual also includes information offered by EVERHARD, which has found to be of value. EVERTRENCH injection moulded polypropylene Arched Liners is used for "Conventional" evapotranspiration- seepage ( ETS) and evapotranspiration-adsorption (ETA) layouts described in the standard. All waste-water poses a health hazard. All layouts for Wastewater disposal land application areas must be designed by competent and authorised persons, taking the following factors into account: The Volume of wastewater, based on household size and appliances. The rate of absorption of the surrounding soil. Limits imposed by site conditions, such as slope, contours, prevailing wind and permanent shade etc.. oom Before beginning design and construction of wastewater disposal system, check State and local authorities for requirements for your area. Conventional trenches and beds may not be permitted. Plants should be selected from approved lists for disposal areas, to minimise root intrusion problems. Method 1: Trenches: These are generally used in sites where soil is permeable enough to allow projected amounts of wastewater to drain freely into the trench floor. Trench should be wide enough for the EVERTRENCH Liner and deep enough for the selected Liner to be not less than 150mm below the surface. 1. Excavate the trench along a level site contour, with the floor not less than 50mm deeper than the invert of the pipe from the Septic Tank or sullage distributor, with at least 150mm cover over the top of the Liner. 2. The trench floor should be level, evenly raked, and have no low spots which would allow “ponding”. Allow at least 75mm overlap for each length of EVERTRENCH Liner. Fit Three Brace Bars into each Standard EVERTRENCH Liner, the first 220mm from the inlet end, then equally spaced along the excavation 5. Cut the pipe entry hole in one Trench Liner End Cap, and fit the Caps to the Liner. Connect piping from the Septic Tank or Sullage Distributor. Lay geotextile fabric over the full length of Trench Liner. Place a 150mm layer of 20 - 45mm aggregate material along both sides of the Trench Liner, and at both ends to secure the End Caps. Rake level 8. Cover the installation with a layer of topsoil, less permeable than the parent soil to help prevent stormwater entering the trench. Leave a slight mound for natural compaction. Turf may be laid over the trench area. DO NOT COMPACT the trench area or expose it to traffic. Method 2: Beds: These are generally used where soil conditions do not allow the planned volume of wastewater to drain freely from normal trench systems. Evapotranspiration beds encourage treated wastewater to be taken up by plant roots over a wide area, as well as draining into the soil, offering additional safety for seepage systems. Beds consist of standard width trenches, deeper than nomal, with the area above the selected Trench Liner of much greater width, and filled with material allowing easier penetration of roots and transfer of moisture. Bed designs may vary widely, depending on soil conditions. BW NO 1. Excavate a bed area between 1000mm and 4000mm wide, at least 300mm deep along a level site contour. 2. Excavate a central trench along the full length of the prepared bed, to take a selected Liner. The top of the Liner should be level with the bottom of the prepared bed, and the trench floor not less than 50mm below the pipe from the Septic Tank or sullage distributor. The floor should be level, Sand evenly raked, with no low spots. 3. Allow at least 75mm overlap for each length of EVERTRENCH Liner. 4. Fit Three Brace Bars into each Standard EVERTRENCH Liner, the first 220mm from the inlet end, and then equally spaced along the excavation . Cut the pipe entry hole in one Trench Liner End Cap, and fit the Caps to the Liner. Connect piping from the Septic Tank or Sullage Distributor. 6. Lay geotextile fabric over the full length of the Liner. 7. Place a 150mm layer of 20 - 45mm aggregate material along both sides of the Trench Liner, and at both ends to secure the End Caps, and rake level. 8. Cover the Liner and the floor of the excavated bed with 100mm of coarse sand, then with sandy loam. 9. Laya final 150mm layer of topsoil less permeable than the parent soil, to help prevent stormwater entering the bed. 10. Leave a mound for natural compaction. Turf may be laid over the area. DO NOT COMPACT the bed area or expose it to traffic EVERHARD INDUSTRIES Pty Ltd recommends a non-woven needle punched Geotextile designed for waste-water disposal land applications aw IMCM-203.07.09.2020 © Ecoflo Wastewater Management Pty Ltd Page 22
