Frequently asked qestions about the Naïade
How much water can be tapped at any time?
The Naïade unit will give up to 5 liters per minute of treated water if the tank is filled.
Will the unit work during cloudy days or monsoon periods?
The Solar Panel will generate sufficient electricity during cloudy days to operate the unit. The built-in back-up car battery will ensure production of safe water during dawn or dusk and heavy monsoon.
What if the water contains high level of sediment/silt (like clay or sand)?
The filters will clog more rapidly and may have to be washed more frequently; in extreme cases it may be advisable to use a sedimentation tank or trough with filter cloth such as a sari or sarong to settle/remove the solids before pouring the water in the tank.
How often do the filters need to be replaced?
The filters are of robust material and can be washed many times; if handled carefully they should last more than two years.
How often does the UV Lamp has to be replaced?
The lamp will last for 3 years if the unit is used during day-light only, or 2 years if used with back-up battery.
What maintenance is required?
The filters must be washed when flow capacity is dropping or unit overflows when filling; the solar panel must be kept dust-free by rinsing/wiping; we recommend to subscribe to a maintenance program offered by the local dealer to control/maintain the unit at least once every 6 months to guarantee a long and trouble-free life of the unit.
When do we know the UV lamp has to be replaced?
Built-in electronics will register the used time of the lamp and a light on the front of the unit will indicate when the lamp needs to be replaced by the dealer.
Can water be used if the UV lamp/unit is defective?
The built-in valve will not open if the lamp is not working or the filters are not in place.
Can we replace the filters/ UV lamp ourselves?
Filters can be replaced by the original spare filters by the user; the UV lamp has to be replaced by a qualified local dealer.
Are there any other parts that need to be replaced?
All components are designed and tested to last for more than 10 years under tropical conditions except the filters and UV lamp that are consumables.
