7.1.5 Cleaning the gauge glass
1. Empty the container, remove the filter and the coffee 
blender.
2. Take the gauge glass lid (fig. 14A) off by pulling it 
vertically up from the protector profile. 
3. Take a dry cloth, and use it to take the top of the gauge 
glass (fig. 14C) from the recess and pull the gauge glass
carefully diagonally up out of and loose from the tap 
connection. 
4. Remove the bottom tulle (fig. 14F) from the gauge glass 
and clean the gauge glass with the help of the supplied 
gauge glass brush. (careful fragile!)
5. Moisten the gauge glass ends + tulle and put the tulle 
back in the glass and push the gauge glass into the tap 
connection with the tulle (fig. 14G).
6. Always put the gauge glass lid (fig. 14A) vertically on the
protector profile, push the top tulle with the index finger 
(in the middle of the gauge glass lid).
Please note: make sure that the gauge glass lid stays 
firmly pushed against the container wall when placing it. 
Only then the gauge glass will stay well. (The lip in the 
gauge glass lid (fig. 14A) must be behind the holding 
plate (fig. 14B).
Tip: On the inside of the gauge glass protector is a spare
gauge glass (fig. 14D). The assembly of the gauge glass
system is much easier if you moisten the gauge glass ends
and tulles well.
