Cleaning and maintenance
After every 50 cycles, the DAC Universal will give a 2 second acoustic
alarm and the display will indicate as shown on the left. This message
reminds the user that the weekly cleaning/maintenance according to the
Check & Clean (C&C) is due. The Check & Clean guide is included with
the DAC Universal.
The table below shows how often cleaning/maintenance should be
carried out. The numbers at the far left of the table correspond with the
subsections in this chapter.
The frequencies indicated are based on approx. 10 complete cycles per
day. If the DAC Universal is used more frequently, please adjust the
cleaning/maintenance intervals accordingly.
Spare parts and consumables for the DAC Universal are available from
your local authorized dealer. Please see "Accessories" and
"Consumables, spare parts, and tools“ for the respective REFs.
