PREPAR ATION OF THE A 250
en
Please observe the accompanying instructions for
starting the A250.
ON WATER HARDNESS
The BONECO U350 is supplied with an A250. The gra-
nulate contained in it filters the lime out of the tap water
so that it is not released into the room air. Hard tap water
accelerates saturation of the granulate so that the A250
must be replaced earlier.
Dispose of the saturated A250 with your regular
household waste.
White dust around the appliance is a sure indication that
the A250 has run its course. You can obtain replacements
from your BONECO specialist dealer or our online store at
