7. MAINTENANCE & DOWNTIME
All BWT AQA drink water dispensers are technical devices which provide drinking water to the end user in a
hygienically treated form. To ensure optimum operation and the best possible water quality, correct, regular
and professional maintenance is required.
Note!
If the status lamp for the UV reactor flashes red when water is drawn (see chapter 4.3 "Control panel"), the
UV reactor is defective and must be checked by a service technician.
7.1 MAINTENANCE INTERVALS
The maintenance interval depends on
- the amount of water/water quality used (note filter capacity)
- the ambient conditions
- the local maintenance regulations for drinking water equipment.
» Cleaning and disinfection:
We recommend cleaning and disinfecting the water dispenser and replacing the water filter used at least
every six months.
» UV reactor:
It is recommended to replace the UV reactor used every 10 years or if the LED light on the control panel
(see chapter 4.3) flashes red while water is being dispensed. The service life of the UV reactor varies
depending on the amount of water dispensed. The switching cycles are unlimited.
Caution!
All maintenance work may only be carried out by qualified personnel!
7.2 BREAKS IN OPERATION / DOWNTIMES
The following points should be observed during longer downtimes or breaks in operation:
» Close the shut-off valve in the inlet of the water dispenser
» Disconnect the device from the power supply. Pull out the mains plug.
» Pauses in operation:
- after 2 days: rinse water dispenser with 2 to 3 litres of water before use
- after 2 weeks: before the 1st use of the water dispenser after downtime, hygienise the unit
- 7 days or longer: emptying of the carbonator before disconnecting the unit (see note!)
