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 centered between side walls.
NOTE: Due to the pedestals being man made, the distance to the center may vary from 245-255mm.
Please check before cutting the hole.
STEP 2: POSITION THE WASTE CHUTE
A 240mm hole must be cut in the toilet room floor to accommodate the waste chute.
1
Go to the underfloor area and look for
the hole you have drilled. Check to see if
there is a floor joist, water pipe or electrical
wiring under the area you are going to cut.
Following the provided pedestal floor template, mark the location of the centre hole 245-
255mm from the back wall. Drill a small hole.
Back wallSide wall

©Ecoflo Wastewater Management Pty LtdIMCM-203-2023.08.30 5
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 fix all connections with galvanized framing anchors with 4 nails each leg
(refer to diagram below).
View from under floor
2Following the pedestal floor template, draw a 240mm diameter circle. Cut out the hole with
a jigsaw.

©Ecoflo Wastewater Management Pty LtdIMCM-203-2023.08.30 6
STEP 3: INSTALL THE WASTE CHUTE
First ensure the pad or ground on which the ‘In-service’ chamber will reside is at its final level beneath
the toilet room. It is recommended to install a concrete pad/tiles for the chamber to sit on.
Insert the chute into the
hole

Slide the lid up the chute.
Cut off any excess chute length
20mm below the mark.
Seal and secure the chute to the
floor with silicone. Follow the separate pedestal instruction sheet to install the
pedestal.
Place the chamber in position
and lower the lid. Mark where the
chute meets the hole in the lid.

STEP 4: INSTALL THE WHEELS
Push the wheels onto the ends of the
axle until you hear them click.
Place the axle in position under the
chamber.

©Ecoflo Wastewater Management Pty LtdIMCM-203-2023.08.30 8
STEP 5: INSTALL THE IN-SERVICE CHAMBER
A brush or rubber seal is supplied for
the ‘In-service’ lid and acts as a seal
to prevent any odour emitting from
the chamber.
Add 50mm depth of bulking agent to
the chamber to create a bed. Slightly
dampen with water.
Slide the lid up onto the waste chute
from underneath.
Rotate the lid to lock the catch plates
onto the pins.
Place the chamber underneath the lid
and lower it onto the chamber.
Lock the toggle latches as shown below.
Place brush seal on inside surfaceof
chute extrusion as shown.
For rubber seal: Apply silicone to the inside of
the rubber seal and attach it around the rim
of the hole.

STEP 6: CONNECT THE VENT PIPE AND FAN
The fan is IP68 rated so will not be effected by moisture.
Do not glue the fan housing to
the DWV fittings.
It is recommended that the
fan runs 24 hours a day to
continuously circulate air
through the compost heap.

POWERING YOUR FAN
Mains Power
A 120 /12 volt regulated transformer is included to run the fan from mains power. The positive wire
the transformer is marked with a white line. The fan has anti-polarity protection and would not run if
connected incorrectly. If you have a solar panel, refer to the instructions provided with it.
Connect the fans to the transformer as follows:
1
3

Unscrew the fan housing cover.
Attach the transformer cables to the
terminal block as shown below.
Pull out the transport spacers.
Insert the fan and fan mesh into the
housing, with the fan mesh on top.
Screw fan cover back onto housing. Test the fan. Airflow should be directed
upwards, towards the top of the fan
housing (see arrow).

LEACHATE DRAIN
A leachate drain kit (not including gravel) is available to purchase separately from Ecoflo Wastewater
Management.
Alternatively, if your council allows, you may wish to construct your own leachate drain. The liquid drain
hose should run into either a 50mm PVC pipe (drilled to allow liquid to escape) OR a length of socked
slotted Ag pipe, buried in an absorption trench as shown in the diagram below.

COMPOST 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
When starting or restarting with an empty chamber, add a 50mm starter
bed of 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.
For best results use pine wood shavings or hemp bedding (available to
purchase from Ecoflo, or find at your local hardware or pet store).
We do NOT recommend the use of:
• Sawdust - as the small particles can create an anaerobic condition
within the chamber and small particles can disrupt ventilation.
• Cypress, cedar or eucalyptus wood shavings - due to their
antimicrobial properties.
• Sugar cane mulch - as it makes using the mixer difficult. Any excess
sugar leaching into the compost can attract bugs.
liquiD enzyMes
Enzymes are a natural detergent, not harmful to the culture of
microorganisms in the compost pile. The enzymes act as catalysts,
breaking down grime and mineral deposits into their basic elements, and
helping to accelerate the composting process. Any stain on the pedestal
can be removed with the solution. Refer to instructions on the bottle.
MicroBes
Microorganisms aka microbes are the ones doing the composting in your
toilet. Each microbe packet is full of aerobic microbes, actinomycetes
bacteria and fungi which combine with the natural bacteria in the waste
to convert it into nutritious fertile compost. Refer to instructions on packet.

©Ecoflo Wastewater Management Pty LtdIMCM-203-2023.08.30 15
STARTING WITH AN EMPTY CHAMBER
Before connecting your chamber to the waste chute, add an even 50mm layer of bulking
agent and dampen slightly with water. Complete the installation of the chamber (refer to
Step 5, Install the In-Service Chamber). You can start using your chamber now.
1
After 7 days of use, mix half a packet
of microbes with warm water in a
bowl. Add this to the chamber through
the pedestal. Reseal the packet and
store it at room temperature, out of
direct sunlight.
2Around 14 days later, add the rest of
the packet of microbes mixed with
warm water to the chamber through
the pedestal.
Your system is now fully activated with
live bacteria.
3
Repeat steps 1-3 each time you restart with an empty chamber.

MAINTENANCE
Daily or weekly
• Clean rest room and toilet fixtures using only biodegradable cleaners (enzymes)
• Add 1 cup of bulking agent to toilet after every solid use
MonThly
• Inspect the ‘In-service’ chamber. Depending on usage, prepare an empty chamber for use once
the chamber becomes full (refer to Rotating the Chambers, page 18)
• Check vent pipe and remove any foreign matter
• Check the fan is operating
• Check that the system is draining correctly
• Remove and clean the fan and fan mesh. Ensure the fan is free of dust and moving easily
TiPs
• Carry a spare fan
• Periodically check your drain hose (aka excess liquids hose) for blockages. Wear protective
clothing and gloves. To check if there is any blockage around the drain outlet under the
perforated false floor, disconnect the drain hose from the chamber and pour hot water in the
chamber. To check if there is any blockage in the drain hose, pour hot water down the hose.
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.

©Ecoflo Wastewater Management Pty LtdIMCM-203-2023.08.30 18
ROTATING THE CHAMBERS
The chambers will need to be changed on a regular basis. A sufficient number of chambers must be
purchased to allow the ‘out-of-service’ chamber a minimum of 6 months to compost (depending on
the climate) from the time they are disconnected from the waste chute.
safeTy wear
When handling compost it is important protect yourself from exposure to any potential pathogens.
Wear safety materials such as gloves, long sleeves, goggles and a dust mask.
Optional: Remove dust plug
to drain excess liquids.
Disconnect the vent and drain system
from the chamber, and immediately
plug the liquid drain outlet with the
dust plug. Lift the in-service lid up the
chute and leave it there.
Remove the chamber from under
the floor. Place the lid of the empty
chamber onto the full chamber.
Add the 50mm pipe and vent to
the out-of-service chamber. We
recommend placing this chamber
in a warm, sunny position until it has
finished composting.
Pour a small bucket of bulking agent
down the pedestal to cover up the
waste pile before removing the full
chamber.
Add an even
50mm starter
bed of bulking
agent to the next
empty chamber
for in-service use.
