EcoLet™ Maintenance Instructions

Routine care varies by model. Scroll to find the instructions that suit your system type.

EcoLet™ 25a & 65a

Adding bulking agent

There are two practical ways to manage bulking additions:

• Weekly top-up: add fresh bulking material regularly to maintain the main chamber at the correct operating depth.
• Scoop-per-poop: add a small handful after each solid deposit.

WCTNZ® recommends approved bulking materials such as WCT | Eco Mix 40 and WCT | Eco Mix 20 (Quick Bag).

Adding microbes

Use WCTNZ® | Microbiota MicrobeBURST™ or the supplied microbes as required when the composting process slows or the pile is not reducing in volume.

Moisture checks

• Too wet: if liquid remains on top of the pile or the tray liquid hose rises above the preferred level, increase the heater setting and add more dry bulking material.
• Too dry: if the pile forms hard lumps or toilet paper remains dry on top, turn the heater down/off and add about 0.5L of water.

Heater settings

• Green light: fan only – default running setting.
• One amber light: fan + 50% top heater – often useful in colder conditions.
• Two amber lights: fan + 50% top heater + 100% bottom heater – use when tray liquid is more than half full.
• Three amber lights: fan + 100% top heater + 100% bottom heater – use when the pile is too wet, when there is indication of overflow, or before opening the collection drawer.

Emptying the tray

It is normal for the compost tray to become full quite quickly. Let the tray remain full while the material continues composting. Depending on usage and climate, this can take about 2-3 to 8-12 weeks or more for holiday homes. As a general rule, empty the tray when the pile in the main chamber reaches the top mixing arm.

• Turn the heater to the highest setting for a couple of hours before opening the drawer so excess liquid has time to evaporate.
• Do not open the front cover if the overflow hose is showing pooled liquid in the base of the unit.
• Always wear gloves and a dust mask when handling compost.
• Completed compost is best buried in a non-edible garden, subject to local council requirements.

Cleaning

Wipe down the seat and housing as part of normal cleaning. WCTNZ® recommends Nature Flush Enzymes for routine cleaning around composting systems. Avoid harsh anti-bacterial or abrasive cleaners inside the composting chamber.

Important do-nots

• Do not use anti-bacterial cleaning products inside the system.
• Do not use sugarcane mulch or long stringy fibrous materials.
• Do not use the bowl cover while the system is in normal use.
• Avoid very fine bulking products that compact and block drainage.

EcoLet™ Separera Mini UD-C & UD-S

Adding bulking agent

Add a small handful or scoop of approved carbon material into the solids chamber after each solid deposit.

Keeping the urinal fresh

Keep the urine bowl and line clean. For ongoing freshness, WCTNZ® recommends regular rinsing and compatible cleaners such as Nature Flush Enzymes.

Separera Mini UD-C – urine container care

• When the urine container is full, the indicator changes from green to red.
• Disconnect power, remove the top, lift out the container, empty it, rinse with hot water, then refit it and confirm the indicator returns to green.

Separera Mini UD-S – urine extraction care

• Flush the urine bowl with water weekly to reduce salt build-up.
• Make sure the urine hose falls away from the toilet continuously.
• For longer runs, connect to a suitable larger pipe as recommended in the manual.

Solids handling

With normal use, a family of four can produce around 7 litres of solid waste per week. As a guide, after 2–3 weeks of use by four people it may be time to change the solids bag/chamber. If you want the material to compost further, empty it into a separate external chamber with a little bulking material and leave it to mature further in a shaded place.

General care

• Use mild or compost-safe cleaners only.
• Keep the fan running and the vent line clear.
• If odour develops in the room, check the vent seals and room air supply first.
• Review the toilet annually to make sure airflow remains unrestricted.
