Operation occurs when the inputs "Start" and "U+" have been separated, that is, after the differential pressure has fallen below the set value. through this it is guaranteed that a maximum quantity of water is available for reverse rinsing. If reverse rinsing starts immediately irrespective of the duration of the differential pressure signal, then the inputs should be connected instead to "U+" and "SIGN" . The DDS 76 differential pressure switch can only be used where F 76 / F 76 S-F fine filters are also installed. 1 Use appliance only: q In good condition q According to regulations q With due regard to safety 7. 3 Immediately rectify any malfunctions which may influence safety. 4 The Z 11 AS automatic reverse rinsing actuator is exclusively for use in reverse rinsing applications with Honeywell Braukmann filters and filter combinations.
