DUNNY LIGHT FAQ
The light is not working
The internal battery has no power – take the unit outside for one to two days to allow recharging
No movement has been detected – check the sensor is clean and not damaged.
Unit has become damaged by misuse / tampering – check for damage to light and sensor
The battery needs to be replaced. The battery lifecycle is typically two years – depending on use. To replace the battery, remove Dunny Light from the latrine, remove the 10 screws on the underside of its body, separate the two halves, remove the old battery and replace with new.
What is the best position for placing the latrine portable unit?
Clear, unshaded locations are best. Shaded areas will still work but the charge capability of the solar panel will be restricted and so the number of nightly operations of Dunny Light might be less.
If you have placed the unit inside, please note it will not be able to charge and will only work until the internal battery becomes flat. You will then need to place the units outside to recharge.
Can I adjust the time the light is on for?
No this has been pre-set to around 90 seconds and can NOT be adjusted
Can the light be set to permanently on?
No, it can only operate via the PIR sensor and run for 90 seconds at a time
Can the light be set to come on in the day?
Yes if you set the switch to “Auto day night” position
I am only getting around 100 activations per day in the winter. Why?
The time of year and how much sun hits the panel will vary the charge time of the internal battery. But the unit will work with whatever energy is in the battery.
Summer charge times could be as low as five hours of daylight to fully charge the battery
Spring and Autumn charge times will be between eight and 15 hours of daylight to fully charge the battery
Winter charge times could be as long as three days of daylight to charge the battery from flat to full.
In most cases, however, the battery is never being charged from flat because the 240 nightly operations will usually never be fully used, particularly in the winter, thus the reduced performance of the solar cell in winter is compensated by lower use of the latrine.
