3. Cut a hole in the floor according to the specified dimensions.

Step 2: Position the Waste Chute

1. Drill a 240mm hole in the toilet room floor to accommodate the waste chute.
2. Check for any floor joists, water pipes, or electrical wiring that may interfere with the installation.
3. If there is a joist blocking the way, either reposition the waste hole or install trimmer joists.

Step 3: Install the Waste Chute

1. Ensure that the pad or ground level beneath the toilet room is at its final level.
2. Insert the waste chute into the hole, marking its position.
3. If additional length is required for under-floor areas exceeding 1200mm, connect multiple waste chutes together using stainless steel self-tapping screws.

Step 4: Install the Wheels
Attach the wheels to the compost chamber for easy mobility.

Step 5: Install the Compost Chamber

1. Apply the supplied brush seal to the inside surface of the “In-service” lid to prevent odor emission.

TOOLS REQUIRED

CLASSIC 850 SCHEMATICS

If you are planning to excavate an area under the house for the compost chambers, please ensure the area is well- drained and any retaining walls are built to the satisfaction of the local authority.

INSTALLATION

STEP 1: POSITION 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.

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 floor to accommodate the waste chute.

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.

NOTE: 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 galvanised framing anchors with 4 nails each leg (refer to diagram below).

View from under floor

STEP 3: INSTALL THE WASTE CHUTE
First ensure the pad or ground level on which the ‘In-service’ chamber will reside is at its final level beneath the toilet room.

Extra Length Required for Under-Floor Areas

If the underfloor height exceeds 1200mm (floor-to-floor), you will require additional lengths of chute, fixed together with small stainless steel self- tapping screws below the flange of the additional waste chute.
As the chute joints are tappered, the top waste chute must be inserted through the toilet room floor first with additional waste chutes added from below.

STEP 4: INSTALL THE WHEELS

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.
4. Place the chamber underneath the chute and lower it onto the chamber.
5. Hook the bungee loops around the lid as shown.

STEP 6: CONNECT 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 and Vent Pipe Installation Details

The fan is IP68 rated so will not be effected by moisture. Do not glue the fan housing to the DWV fittings.

STEP 7: CONNECT THE FLEXIBLE AIR HOSE AND EXCESS FLUID1 2HOSE TO THE CHAMBERS

POWERING YOUR FAN

Mains Power
A 240/12 volt regulated transformer is included to run the fan from mains power. The positive wire on the transformer is marked with a white line. The fan has anti-polarity protection and would not run if connected incorrectly.

Connect the fans to the transformer as follows

We recommend a spare fan is kept on hand at all times, particularly after a year of use.

• Shop fans and solar : ecoflo.com.au/products/fans-and-solar

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 Nature Loo users report successful composting without the use of any additives, we strongly recommend the use of the following items (not included in the package) 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.

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 sufficient 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 a Chamber 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 flood. 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 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 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 composted, 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 power 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.
