DWM-203 is fitted with indicating light and sound indication of module resources. Indicating light and sound indication of
DWM-203 is configured to work with water corresponding to sanitary regulations and norms.
The indicating light for each of the filtration units is individual (fig. 15): modules K2 and K5 of the prefilter unit correspond
to indicators 1 and 4, to the reverse osmosis membrane unit- indicators 2 and 3.
The flickering of the filtration units
, accompanied by a periodic sound signal, informs about the used resource
of the corresponding module. In this case, it is necessary to replace this module with a new one.
A continuous signal from the light indicators of the filter units
indicates the unworked resource of the
modules.
LED indicator 5
(see figure 15) will flash in the event of a malfunction, at the rest of the time it is lit continuously,
which indicates the connection of the DWM-203 to the mains.
