Water Dilution
ATTENTION:
Risk of scale deposits. Correctly set the Water Dilution Interval (Step 4D in Installer menu) and
No. of Cycles (4D in Installer menu) according to the water quality or conductivity during commissioning of the
humidifier. Failure to do so will result in scale deposits on the evaporation module and the media panels.
The process of evaporative humidification results in built-up of dissolved solids in the water tank. To control this, a water
dilution cycle is run at specific intervals to clean the tank. This water dilution cycle does not interrupt normal system
operation. During the cycle, both the inlet and drain valves open to renew the water in the tank. The interval and number
of cycles of the water dilution cycle are directly related to the total dissolved solids or water conductivity of the water used.
This setting should be defined at the time of installation and commissioning of the humidifier based on the quality of water
as shown in the table below.
