3.3 FUNCTION OF THE INTEGRAL UV SYSTEM IN THE AQA DRINK PRO 20
The AQA drink Pro 20 water dispenser has an integrated UV system with a lamp output of 11 watts.
When the UV lamp is in operation, the LED indicator on the front of the control panel lights up. If a
button is pressed for water, the water is dispensed after about 2 seconds of UV sterilisation. If the
water dispensing function does not start, press the water dispensing button once more. After each
time water is dispensed, UV sterilisation continues for approximately 120–180 seconds. To ensure
long-term hygiene, even when no water is drawn, the UV lamp lights up automatically every two
hours for 120 seconds.
Note!
If the UV lamp is defective or is not connected, water can still be freely dispensed without re-
strictions. However, an acoustic warning signal sounds when the selection buttons are pressed
and the LED indicator on the operator panel flashes.
If a leakage or full drip tray is reported (see chapter 5.7), it is not possible to draw water.
