INSTALLATION
STEP 1: POSITION THE PEDESTAL
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.
NOTE: Due to the pedestals being man made, the distance to the centre may vary from 245 to
255mm. Please check before cutting the hole.
STEP 2: POSITION THE WASTE CHUTE
A 240mm hole must be cut in the toilet room oor to accommodate the waste chute.

Go to the underoor area and look for the hole you have drilled.
Check to see if there is a oor joist, water pipe or electrical wiring under the area you
are going to cut.
If there is a joist in the way, either reposition the waste hole OR install trimmer joists to
each end of the cut joist, and x all connections with galvanized framing anchors with 4
nails each leg (refer to diagram below).

EXTRA LENGTH REQUIRED FOR UNDER-FLOOR AREAS
If the underoor height exceeds 900mm (oor-to-oor), you will require additional lengths of chute,
xed together with small stainless steel self-tapping screws below the ange of the additional waste
chute.
As the chute joints are tapered, the top waste chute must be inserted through the toilet room oor
rst with additional waste chutes added from below.
STEP 4: INSTALL THE WHEELS
Attach the wheels to the ends
of the axle and place under the
chamber.

STEP 5: INSTALL THE COMPOST CHAMBER
1. A brush seal is supplied for the
‘In-service’ lid and acts as a seal to
prevent any odor emitting from the
chamber. Remove the adhesive cover
and place the brush seal on the inside
surface of the lid as shown below.
2. Add 50mm depth of bulking agent
to the chamber to create a bed.
3. Slide the ‘In-service’ compost
chamber lid (with pre-cut hole)
up onto the waste chute from
underneath.
5. Hook the bungee loops over the
knobs as shown.
4. Place the chamber underneath the
lid and lower it onto the chamber.
Place brush seal on insi
de surfaceof

Do not glue the fan
housing to the DWV
ttings.
It is recommended that
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.

COMPOSTING ACCELERATORS
Whilst Clivus Multrum users report successful composting without the use of any additives, we strongly
recommend the use of the following items in order to optimize composting, particularly when the toilet
is in permanent use by more than two people.
Bulking agenT
This 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 eucalyptus wood shavings due to their antimicrobial
properties.
• Sugar cane mulch as it makes using the mixer difcult.
liquiD 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
ask is provided. Any staining of the pedestal can also be removed with
the spray.
MicroBes
This should be used each time a chamber is changed to kick start the
process in the new chamber.

ROTATION OF 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.
your firsT roTaTion of The chaMBers:
The Nature Loo composting toilet chambers will need to be changed on a regular basis. A sufcient
number of chambers must be purchased to allow the ‘Out-of-service’ chamber to have a minimum of 5
months (depending on climate) from the time they are disconnected from the waste chute.
Prepare a new ‘In-service’ chamber for use (refer to Step 5: Install the Compost Chamber, page 7).
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 attached 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 achaMBer To service:
1. Ensure all hose and vent connections are clear.
2. Prepare the ‘In-service’ chamber for use (refer to Step 5: Install the Compost Chamber, page 7).
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 chamber. Connect the second
liquid drain hose from the chamber to the trench.

TROUBLESHOOTING
Please reaD This secTion Before using your ToileT.
Nature Loo toilets have proven themselves to be one of the easiest systems to manage. However, being
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 ood. Check the drain hose is not blocked and ush with a hose if necessary. You may need
to change chambers if the blockage is in the chamber and thoroughly ush 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 inefcient composting by breaking down the solids and thereby speeding up
decomposition.
The ‘ouT-of-service’ chaMBer is coMPosTing Too slowly:
This may happen due to one or more of the problems described above. You could 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. However,
if you nd the pile is drying out too quickly put the chamber in a shadier position.
If you nd that 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 composted,
dispose of the waste as normal and order an extra chamber from Ecoo.

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, or blockage in the vent pipe, liquid drain hose or tting, please see
the “‘In-service’ chamber is lling too quickly” section for how to resolve this problem.
The Power has faileD resulTing in ToileT rooM oDours:
Cover the pedestal with cling lm until the power is restored. If you are connected to mains power
consider installing an Uninterrupted Power Supply (UPS), available at Ecoo 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 ow.
• Add a wind assisted turbo vent to the Vent Stack.
