Unit dimensions
25e: 710mm L x 550mm W x 650mm H
65e: 810mm L x 650mm W x 660mm H
THREE IMPORTANT THINGS TO REMEMBER
1. When the toilet is used, room temperature should be at least +18°C.
2. If you are away for more than two days, always turn the power off and put the cover in the
seat opening, otherwise the compost will become dry.
3. The heating element in the room can also be switched off, the composting toilet will not be
damaged by freezing.
How the EcoLet works
EcoLet is a self-continued biological toilet that composts waste, toiletpaper and evaporates
liquid. The composting process takes place using nature’s own microorganisms, without the
need of any chemicals. The toilet should be used as any other. Controlled air supply and heat,
as well as regular mixing of the compost accelerates the composting process and converts
toilet waste into eco-friendly humus. This makes a nutrient rich supplement for you garden.

Installation
Tools required
• Drill
• 55 mm Hole saw or jigsaw
• Saw
• Measuring tape
• Sealant/adhesives
Instructions
1. Position the unit on a level surface leaving enough space in front of the unit to remove the
compost tray.
- Minimum distance from the back wall to the front of the tray is 1100mm.
- Keep in mind you will need a 240V power point available somewhere near the unit.
- Be mindful of how the vent is to be installed as this may impact windows, etc.
2. Install the vent pipe either straight up through the ceiling or out through the wall and up
the exterior of the building.
- An optional vent wall kit is available.
- Do not use bends over 45’.
3. Installtheroofashingandsealasrequired.
4. Insulate all parts of the vent pipe in roof cavities or outside the building using the insulation
provided and shield with 100mm pipe provided. Source extra insulation if required.
5. Fit the insect netting to the top of the vent.

Operation
Starting with empty toilet
1. Mix the 5L bag of Peat Moss with the two 12L Mini Hemp bales provided with your toilet,
this creates a very absorbent bulking agent.
2. Empty this bulking agent into the main chamber of the toilet through the toilet seat, this
will fall down into the collection tray as well.
3. Connect the mains plug into a grounded wall socket, switch the system on and turn the dial
totherstpositionsothatonlythegreenlightison(justthefan,nottheheater)
4. Lift the seat lid and lean it against the top of the unit to activate the seat sensor (via a
magnet on the lid) this stops the mixing arm if it is in motion; once released (putting the
seat down) it will automatically make one full rotation. Complete this action of lifting the lid
and putting it down to ensure the seat sensor is working and the mixing arms are rotating
in full.
5. Make sure that when the fan is running you don’t have the bowl cover in place, this acts like
a plug and seals the composting chamber only when the system is not in use.
6. Now you may switch the dial to the second position to turn the heater on and your system
is ready for use. This setting will be subject to change as you continue to use the system.
In the rst week
1. Monitor the main composting chamber every day
– The bulking agent should be porous and have a moderately moist texture; the ideal
moisture content for compost is 60%.
– The mixing arm should automatically activate after every use because of the seat sensor.
– The mixing arm will activate occasionally when not in use. This is due to the mixing
mechanism also being on a timer separate to being activated by the seat sensor.
2. The collection tray will be full of the dry bulking agent that you used in setting the system
up for use. Empty this back into the main composting chamber (it’s the equivalent of
“turning” a compost pile by making more room at the base for the compost to fall)
3. Once you have some solid waste in your composting chamber you can start to introduce
your microbes. This is a crucial step as it is a closed system so there is no guarantee these
microbes will occur naturally to compost your waste; without them you’re just collecting
waste.
4. Add a handful of bulking agent for every #2 you do – or about 1 litre once a week.
Checktheuidlevelindictortubeonthesideoftheunit
– If you can see liquid in the tube, turn the thermostat up one click to aid evaporation.
– The thermostat setting may vary depending on the use patterns and climate.

Liquid in the level tube
The level tube (on the right hand side, viewed from the front) (#28) show how much liquid
thereisinthetray.Thetubeshoulddenitelynotbefull;thismeansthetrayisfullofliquid.
Half full of liquid in the tube is alright.
Correct setting
At the correct setting, the compost has a porous and moderately moust consistency. If liquid
stays on top of the conpost and seeps into the tray slowly, then the compost is too wet and
can no longer absord the liquid as intended. Increase the setting and add a few litres on
humus starter. On the other hand, if hard lumps form or toilet paper remains on top, so that it
doesn’t get soaked and mixed in properly during mixing, the compost is too dry. If so, turn the
setting down and sprinkle a few litres of water over the compost.
If you have model 15e, make a couple of extra turns with the handle.
How to and how often to empty the tray
This depends on use, but the system is designed to be emptied every 6 to 12 weeks when
used to its maximum capacity. As a general rule, once you are collecting completed compost
from your collection drawer you can empty it once the compost pile reaches the top mixing
arm.
Becarefulnottoopenthecollectiontrayifyouroverowindicatortube(LHS)isshowingthat
there is liquid pooled in the base of your unit, outside of your collection drawer.
When the tray slides out the indicator hose (RHS) needs to be unplugged to remove it fully, so
make sure you have reduced the leachate level as low as possible.
The compost process takes at least three to four months so you may not see compost in the
rstfewmonths.Ifyourcollectiontraycontainsonlybulkingagent,thenadditbackintothe
composting chamber through the toilet seat.
If you are at the stage of seeing completed compost you can use this in your garden, we
recommend burying it like a fertiliser in a non edible garden. Fully composted waste will be
pathogen free, but burying it will reduce the likelihood of contact with animals or people
(better safe than sorry).
Caution
• Only use wood shavings and/or peat moss in your EcoLet.
• DoNOTusesugarcanemulchorotherstringybrousmaterial.

Maintenance
• Checktheuidlevelindicatortuberegularlyandadjustthermostataccordingly.
– Fluid showing = turn thermostat up
• Add bulking agent regularly.
• Empty the compost tray BEFORE it is full.
– Mostpeopleemptyitonceamonthtoavoidoverlling.
When to reintroduce the microbes
As you use the system, the microbes that you introduce will spread through your composting
chamber which is aided by the mixing mechanism. If they are able to thrive in the composting
chamber environment you may never need to reintroduce them. An optimal composting
environment for these microbes is moist and warm. You will therefore want to consider
reintroducing microbes if your system has:
• Completely dried out. In dry conditions microbes will start to hibernate and eventually die
• Gone septic. If your system is full of liquid the microbes will drown
• Becomes too cold. Microbes will start to hibernate in cold temperatures
It can also be “refreshing” for your compost pile to have some new microbes added into the
top layers. This can be helpful if you have been using the system for a long time or if you have
left the system unattended and turned off.
Thankfully, there’s two really easy ways to add microbes into the composting chamber:
• Add Nature Quick Microbes
• Add fully composted material (it will still contain a population of microbes)
When to turn the system off
If you’re going to leave your system unattended for a long period of time, you can switch it
off and place the bowl cover into the seat. This seals the chamber and will prevent any smells
from entering your bathroom. Then you can comfortably turn the system off at the wall socket
without worrying about emptying the contents.

Troubleshooting
Odours detected
• Urine/damp odour
– Turn thermostat up one click and monitor
– Ensure vent pipe is well insulated (to prevent condensation issues)
• Strange burnt odour
– Turn thermostat down one click and monitor
– Check moisture level of the pile. If it appears dry, sprinkle 500ml of water on bulking
agent.
Liquid leaking onto oor
• Checkuidlevelindicatortubeonsideofunit.
• If liquid is visible in the tube, turn the thermostat up one click and monitor.
• Ensure the vent pipe is well insulated (to prevent condensation in the vent pipe).
Mixing arms are not turning
• The mixing arms moves very slowly and the seat sensor will stop them from moving when
you lift the toilet seat lid. To check if the mixing arms are moving:
1. Lift the toilet seat up to activate the seat sensor (this is the magnet in the lid making a
connection).
2. Make sure you can see into the composting chamber; you’ll need to depress the toilet
seat for the 25e or lift it for the 65e to move the chamber screen.
3. Now release move the toilet seat lid away from the unit to release the seat sensor.
• You should see the mixing arms start its rotation. If you don’t, you’ll want to start
troubleshooting:
4. Check that your lid has a magnet.
5. Make sure the shear pin hasn’t broken.
6. Can you hear the mixer motor?
