AS SUPPLIED — FLOW OPERATION
The unit is configured for Flow operation. Install the flow meter in the dishwasher’s water infeed. Connect the dosing unit to a suitable supply within the dishwasher so that isolating the dishwasher also disconnects power to the dosing unit. During operation, the unit measures the water taken in and doses according to that volume and whether the dishwasher is starting up or running.

SET PIN to prevent unauthorized access to settings
In Setup, select the ‘set PIN’ function, enter four digits. For each digit: LEFT decreases by one; MIDDLE increases by one; RIGHT accepts and moves to the next. Press once per change; there is no auto-repeat.
CONFIRM PIN Enter the same four digits again. The unit compares them, displays the new PIN and returns to the menu after a short delay. Four identical digits such as 1111 are rejected as weak. Record and retain the PIN securely; it cannot be retrieved.
