OPERATING INSTRUCTIONS
•Switch on the doser using the external switch (or by plugging in the flying socket)
•Set desired water quantity using + and – keys. Setting appears on display (13).
Increments/decrements may be obtained in three different ways :
1. Step by step : pressing once + and = keys
2. Continuous : keeping constant pressure on + and – keys.
3. Fast : 3 seconds after keeping constant pressure on + or – keys.
•Press START key (8).
Water delivery may be stopped at any time by pressing STOP/C key (6). Quantity of water
delivered will then flash on display (12). To resume delivery of remaining water press
START key. Press STOP/C key and the original litre setting will reapears on display. Press
STOP/C key again to clear memory.
•Water temperature is selected by turning the temperature regulation knob (5) : the
temperature is shown on the electronic thermometer display (12). When regulating the water
temperature wait a few seconds between adjustments so as to allow the temperature to
stabilize.
•Quantity in memory is retained at the end of each dosing. Simply press START key if
identical successive dosing are desired.
Memory is protected against power failure; pre-set dosing can be resumed pressing START
key when power is restored.
•To ensure optimum operation the warm water temperature must be at least 10ºC higher than
the required delivery water temperature and the cold water should be at least 5ºC lower. Low
temperatures (below 10º - 15ºC) may be obtained only when using a refrigerator.
FAULTY OPERATIONS AND REMEDIAL ACTION
•If during water delivery the litres display flashes and the buzzer sounds intermittently and no
water flows out of the DOX, press the STOP/C key and then the START key :
!If no water flows out of the machine and after 10-12 seconds fault indication restarts,
check the water pipes and ball valve, probably water is not reaching the doser.
!If the water pipes are not obstructed, the water taps are all open and water arrives
regularly to the doser, check that the filter (3) is clean and then press the START key. If
the fault persists, the solenoid valve coil is faulty.
Ask for technical assistance.
•If during dosing, water is at first delivered regularly, but the litres display does not decrement
accordingly or decrements very slowly and/or irregularly, and after a while water delivery
stops, the buzzer sounds and display flashes :
Press the STOP/C key and then the START key :
