3.3 FUNCTION OF THE INTEGRAL UV SYSTEM IN THE AQA DRINK PRO 20
The AQA drink Pro 20 CAS 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 60
seconds.
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.
According to disinfection requirements the UV lamp might light up for longer than the nominal
60 sec. which might heat up the water in the reactor significantly. When this is observed just
flush till nominal temperature is restored.
3.4 AQA DRINK PRO 20 CABINET (OPTIONAL)
The AQA drink Pro 20 water dispenser (fig. 4) is also available with an optional cabinet for install-
ing the water dispenser as a free-standing unit. The cabinet has height-adjustable feet on the
underside and an integrated cup dispenser on the front. A wastewater tank with a wastewater
level sensor is connected to the upper section inside the cabinet (fig. 5 and fig. 6). The cable for
the level sensor in the cabinet is connected to the plug on the left-hand side of the base plate of
the water dispenser.

tion. In addition, the local accident prevention regulations and general safety regulations valid
at the location of the device apply.
Before performing maintenance work on this device, it must be disconnected from the mains
supply.
It must be possible to disconnect the electric current either by pulling out the power cable or
by means of a biploar mains switch at the socket.
If the power cable is damaged, it must be replaced by the manufacturer or a qualified
technician.
Do not use extension cables or multiple adapters.

location.
The device must be secured with an earthing switch. Earthing the device is a legal
requirement.
The electrical connections must comply with local standards.
This water dispenser was designed and constructed in accordance with the Low Voltage
Directive 2006/95/EC and the protection regulations of the EC directive 2004/108 EMC.
In the event of any use other than for the intended purpose, e.g. the use of the water
dispenser for the treatment of water which is not of drinking water quality, drinking this water
may constitute a danger to health:
» microbiological risk as a result of exposure to pathogenic germs
» risk due to high concentrations of heavy metals or organic contaminants
Before maintenance work is carried out on the drinking water supply, disconnect the device
from the water supply. Rinse the water pipe before the device is reconnected.
Comply with all country-specific installation regulations (e.g. DIN 1988, EN 1717), general hy-
giene conditions and technical data relating to the protection of drinking water.
The materials of the water dispenser which are in direct contact with the water comply with
the regulations and and common food industry standards. The device was manufactured
according to the provisions of the Italian Ministerial Decree D.M. 174 of 06/04/2004 and D.M. 25
of 07/02/2012.
Avoid storing the device for unnecessarily long periods in order to minimise the risk of
microbial contamination.
The lines of the coolant circuit must not be damaged because they are filled with R134a gas,
which is highly inflammable. Check the lines on a regular basis.
