We suggest to provide the unit with a temporized discharging system to drain the water tank, as
a bleed-off valve, in order to keep the unit in good working conditions.
The installation must meet the safety requirements provided by local regulation in force.
Follow the regulation of the UNI 8884 standard “Requirements and treatment of water cooling
and humidification system” which provides conductivity <100 μS/cm and total hardness <5° fH
(50 ppm CaCO3).
Make sure that all the connections necessary to operate the equipment have been properly prepared.
2.2 Positioning
The UX humidifier / cooler must be installed horizontally, with the water collection tank facing
down, lifted off the ground.
Use the suitable eyelets to hang the machined or hold it in the correct working position with an
appropriate sealing system (the distance between holes is shown in figure 2.1).
The positioning of the UX must be done by maintaining the minimum recommended distance that allows the
correct operation of the machine and to perform maintenance when needed. Choose the most suitable position
for the humidification and cooling of the environment according to the type of installation adopted.
To avoid fog condensing on the walls, keep a distance of at least 1 mt from the ceiling and from the
walls.
Distance from the front wall must be calculated based on the model and quantity of water nebulized.
The machine installation must meet the safety
distance in accordance with the
DIN UI EN ISO 13857/2008 norm.
