Maintenance And Cleaning - VOLTA U 416 Operating Instructions Manual

Maintenance and Cleaning

Prior to maintenance and cleaning, ensure that
the appliance is switched off and that it is
unplugged from the mains:
Changing the Paper Filter
The paper filter must be replaced if the window
on the filter replacement indicator is completely
red when the appliance is operating at maxi-
mum power and the nozzle is raised from the
floor.
The paper filter should be replaced even if it
does not appear to be full because fine dust can
block the pores in the surface of the filter.
The cover can be opened by pressing the button
and folding back until it locks.
Hygienic filter change: When removing the full
filter bag, pull the closing tab to automatically
close the opening. During this process you must
overcome light resistance when pulling the tab.
Bags full of normal household dust may be dis-
posed of with household rubbish.

Insert the new paper filter to the stop in the
guide rails, only then can the lid be closed. If a
paper filter is not inserted, it is not possible to
close the cover. Please do not use force!
Changing the Microfilter
We recommend replacing the microfilter on
every fifth paper filter replacement, at the latest
when the dust level indicator is completely red
with a clean dust bag and the nozzle raised.
Open the lid and fold up. Remove the microfilter
using the clean hygiene tab (Figure) and dis-
pose of it with the household rubbish. Insert the
new microfilter and close the cassette.
Motor Protection Filter
The motor protection filter is a permanent filter
and does not have to be regularly replaced.
Exception: the filter is damaged.
See under "What to do, if ...".
Cleaning
As required, wipe the housing and the paper fil-
ter compartment with a damp cloth. Do not use
any scourers or any solvents. Occasionally vac-
uum the floor nozzle and brush using the crev-
ice nozzle.
