Caution!
Only open the CO2 gas cylinder a quarter of a turn
(opening the valve completely has no influence on
the amount of CO2 in the water).
Connect the CO2 gas cylinder as shown in Fig. 8.

Note!
The CO2pressure should be set to approx. 1 bar
above the water pressure of approx. 2 bar, i.e.,
approx. 3 bar.
Replacing
Checking:
Check the CO2 pressure at the pressure reducer. If
the current pressure gauge pointer has fallen below
1 bar, the pressure will no longer be sufficient for
the optimum preparation of the CO2 water. Please
change the CO2 cylinder.
Removing:
» Disconnect the power supply of the device.
» Close the hand wheel on the CO2 gas cylinder
by turning it clockwise.
» Slowly open the screw connection on the pres-
sure reducer and relieve any residual pressure.
» Then release the gas cylinder from its holder.
Preparing:
» Remove the thread protector from the new gas
cylinder.
» Open the cylinder valve briefly to remove any
dirt from the cylinder outlet valve.

Caution!
The cylinder is under pressure, open the valve only
slightly and do not direct it at people!
Connecting:
» Screw the pressure reducer onto the cylinder
valve thread.
» If necessary, secure the cylinder in the holder
again.
» Once the gas cylinder has been connected,
connect the device to the mains power supply.
» Check the CO2 pressure, this should be about
3 bar.

5.6 Setting the cooling temperature (CAS)

The thermostat (for setting the cooling temperature)
is located on the left-hand side under the cover. Set
the thermostat to the desired temperature.

5.7 Leakage protection

A leakage sensor is located inside the water
dispenser at the bottom of the front panel. When
this detects water, the LED at the dispensing point
flashes (Fig. 1) and an acoustic signal sounds. If the
device is equipped with a wastewater tank, make
sure that it is empty. If the light is still flashing, the
leak sensor is still detecting water in the device.
Disconnect the water dispenser from the power
supply and contact a service technician.

6. Maintenance and hygiene

AQA drink 1 water dispensers are technical devices
which provide consumers
processed drinking water. In order to guarantee
optimum operation as well as the best possible
water quality. Correct, regular and professional
maintenance is necessary in order to guarantee
optimum operation as well as the best possible
water quality.
Note!
In the event of a defect, the water dispenser auto-
matically emits audible and visual signals.

6.1 Maintenance interval

The maintenance interval is dependent on the
amount/quality of water drawn (pay attention to
the filter capacity) and the ambient conditions. We
recommend having the water dispenser cleaned
and disinfected and the water filter replaced by
qualified personnel at least every six months. It is
also recommended that the UV lamp used should
be replaced every six months. However, this de-
pends on the switching cycles and the number of
times water is dispensed.
