6. Cleaning and maintenance
6.1 Cleaning
Do not clean the device with compressed air!
Only clean from the outside using a lightly dampened cloth with the mains plug unplugged. Ensure that elec-
tronic parts do not come into contact with moisture. Do not use any cleaning products containing solvents!
6.2 Maintenance
Clean the holder for the mixing cup at the unit, the holder of the cup and the seal as well as the prefilter accor-
ding to the level of contamination. The prefilter is located in the mixing/suction connections (6). Switch the
device off and remove the mains plug before changing the prefilter. The prefilter is unfastened by turning it in
an anti-clockwise direction with the help of a size 15 fork wrench and is then cleaned in an ultrasonic bath.
It is then screwed tight again by turning it in a clockwise direction. We recommend changing the prefilter every
1 to 2 years. The prefilter should not just be cleaned once the vacuum takes longer to build up, but at regular
intervals, depending on how much the device is used.
CAUTION
Never operate the device without a prefilter.
The O-ring on the mixing/suction connections (6) and on the mixing spiral should be kept clean in order to
guarantee an optimum vacuum. The vacuum pump does not require maintenance.
