IMPORTANT!
The filter pump or pump contactor has to be wired to BADU Easytronic in a way
which ensures that the pump can only be operated in combination with BADU
Easytronic. It is therefore imperative to observe the wiring diagrams! Addi-
tionally, BADU Easytronic has to be protected by installing a residual cur-
rent-operated protective device.
Please make sure the electrical installation is provided with a disconnecting de-
vice, which allows isolation from the mains with a contact gap of at least 3 mm
per pole. The ambient temperature must not exceed 40 °C.
Improperly connected electrical wiring, overvoltage and a faulty electro-
nic system will void any warranty.
CAUTION: The automatic backwash unit must only be used for swimming
pools and surrounding protected zones if these have been designed in
accordance with DIN VDE 0100 Part 702. Please consult an electrician!
The supply circuit has to be protected by means of a residual current-
operated protective device with a nominal residual current of I
6.
Initial start-up
CAUTION
6.1 Function check
When voltage is applied to terminals 1 and 2 of BADU Easytronic and the unit
is switched on by operating the "red toggle switch", the unit first performs a
function check passing the "filter", "drain", "backwash" and "rinse" cycle and re-
turning to the "filter" cycle. Upon completion of this function check, the device is
ready for operation.
6.2 During the test run, an electrician has to check whether BADU Easytronic is
properly wired to the mains.
6.3 The pump must be switched off when the unit switches cycles.
6.4 Please make sure the shut-off valves installed in the supply pipes of BADU Ea-
sytronic are completely open.
6.5 If BADU Easytronic is installed below the water level, make sure to install a
special spring-loaded non-return valve by Speck in the sewer pipe to pre-
vent faults caused by backflows when the unit switches cycles (refer to
page 23).
6.6 Specified start time for automatic backwashing
You may specify a start time for the seven-day-interval by initiating a manual
"backwash" cycle.
The start time can also be determined by switching on the unit. The same ap-
plies to restoration of power after power failure.
≤ 30 mA.
