3.2 WATER SUPPLY
3.2.1 Recommendation
Our device is designed to be used with any following water type:
✓ drinking water (according to Directive 98/83/EEC, TH
(French grade) between 0 and 40° and conductivity
between 250 and 1000 μS/cm)
✓ softened water,
✓ demineralized water, reverse osmosis water: use
possible under conditions. Please contact our services
The demineralized water is corrosive; use appropriate piping material: stainless steel, PVC.
Softened water: Its use is not necessary, but possible. TH should be kept as constant as possible and between 0° and 2°. A
duplex softener is best suited.
Water analysis is recommended to determine the level of sodium chloride.
Do not hesitate to contact our services for support.
3.2.2 Recommendations on connection
Network water pressure: The pressure must be stable and between 2 bar and 8 bar MAX. in case the water pressure
exceeds 8 bar, a water regulator calve must be used.
Network water temperature: < 40 °C.
Please note that the water supply is connected at the lower part of the unit.
For easy maintenance, the water inlet valve is equipped with a filter strainer which should be checked periodically. It
is essential to install an isolation valve near the humidifier to facilitate maintenance.
OVERFLOW RISKS: it is recommended to install a collecting water tank under the humidifiers to
prevent overflow. This is essential if the unit is installed in false ceilings or above important rooms
(example: museum room, showroom, laboratory etc.). Make sure the container is connected to the
wastewater system.
An excess of sodium chloride may generate foam which disturbs the correct running of the humidifier.
It is essential to install a duplex softener.
