Cleaning the Filters
Continued efficient operation, reliability and a long service life
as well as safety, require inspections and maintenance work
to be regularly carried out by a competent person approved
at the time by the Health and Safety Executive and on an
annual basis.
We recommend making a maintenance agreement. The
operational reliability of the device can be impaired, resulting
in damage to property or personal injury, if maintenance work
is not carried out.
You, as the owner or user, may execute the following
maintenance work yourself:
– Clean and replace the filters in the domestic ventilation unit.
– Clean and replace the filter in the bypass casing (if used).
– Clean the fresh air or exhaust air valves in the living space.
– Reset the time interval for filter replacement in accordance
with section "User Controls"
It depends on the contamination levels how often the filters
must be cleaned or replaced. We recommend to regularly
check the filters during the initial operational period and
assess the need to clean them, e.g. every three months. If
you then feel that the filters are only slightly contaminated or
dirty, you may extend the interval.
NOTE: Replace the filters at least once a year or after a
maximum of 2000 operating hours.
You can clean the filters with a vacuum cleaner. If this is not
enough, the filters must be replaced.
DO NOT clean the filters with water or other liquids.
Dispose of the used filters with the domestic waste.
Cleaning or Replacing the Filter
To check and clean the filters, please proceed as follows:
● Unplug the Atmosorb from the mains.
● Pull the filter out of the unit.
● Remove the filter handles from the filters.
NOTE: Before inserting the filters, please ensure the correct
positioning in order to avoid damaging the filters.
● Position the filter handles on the clean or new filters.
On the one side, the filter handles are fitted with guides which
must be pushed into the grooves in the unit.
– The upper filter of the Atmosorb and the bypass filter are
mounted with these guides pointing to the bottom.
– The lower filter is mounted with the guide pointing to the top.
● Push the filters back into the unit.
●
To operate, plug the mains plug back into its socket .
