Troubleshooting
Water leakage from the tank
Check that the installation of the tank is level.
Check for any damage or holes in the tank.
Check for any damaged or ill-fitted drain pipe-work and ensure that there are no leaks.
Water carries over into air stream
Check the air velocity at the inlet of the evaporation module. Make sure the value corresponds to initial design
data. The limits of the air velocity for the evaporation medium are as follows.
Pressure
With Separator
Without Separator
Negative
14.7 ft/s (4.5 m/s)
11.8 ft/s (3.5 m/s)
Positive
14.7 ft/s (4.5 m/s)
9.8 ft/s (3.0 m/s)
The air velocity might be uneven. Fit a perforated plate before the humidifier.
Ensure that the humidifier media cassettes are correctly fitted and installed.
Verify correct installation of the water distribution drawers.
Loss of performance
The humidifier cassette is blocked or damaged. Check for the damaged media cassettes and replace, if
required.
Ensure that the humidifier media cassettes are correctly fitted and installed.
There is not enough flow of water, check that the flow regulators are not blocked or that the hoses or pipe
distribution in the upper trays are not blocked.
Scale build up on the surface of the media
Excess concentration of minerals and salts in the tank. Check dilution cycle and increase the dilution.
Water quality has changed.
Note:
an accumulation of
dust on the
media
may be caused by
a
failure of the
air
filtration.
Module pump is not functioning
Check that the safety contacts are not open, and in particular the RG high limit switch.
Check that there is a demand for cooling or moisture.
Check that the Evaporative Cooling Humidifier is in automatic mode and in the ON position.
Check that there are no alarms present and in particular a water level fault.
Check that the water level in the tank is sufficient.
