Installation suggestion
The following sketch shows an example of the integration of the IQntrol DOS MODBUS in the swimming pool’s water treatment
cycle. In most cases, a measuring water withdrawal between the filter pump and the filter boiler is sufficient. The water is
recirculated into the clean water line downstream of the heat exchanger. Two ball valves ½“ with immersion pipe for the
connection to the filter piping are provided with the accessories. The immersion pipe of the two ball valves should be shortened so
that it ends approximately in the middle of the pipe.
ATTENTION!
Since both chemicals are mixed in with the measuring water, the measuring water recirculation must occur in the
direction of the flow downstream of the heat exchanger in order to prevent corrosion.
If the pool is being operated with an overflow gutter and a splash water tank, into which freshwater is also allowed
to enter, marked differences in the water quality on the measuring cell and in the basin must be expected. In order
to ensure perfect control quality in this case, it is recommended that the measuring water is withdrawn directly
from the basin, using a separate measuring water pump.
