eta PURIS, Instructions For Use Manual, Page: 24 / 48

AIR CONDITION INDICATION
Air condition signal B6 visually shows the level of pollution by means of three colours.
Red indicates high pollution, orange indicates increased pollution and green indicates low or
zero pollution.
The pollution sensor is able to calculate the number of dust particles PM2.5 – i.e. particles
smaller than 2,5 μm (units: µg/m
3
). The TVOC value represents the concentration of volatile
organic compounds (odour in units PPM). The measured values are alternately shown on the
display B5 .
REMOTE CONTROL
The purifier can also be operated using the remote control C . Insert/replace the CR2025-type
battery as indicated in Fig. 3. The button feature is identical with that on the control panel B .
REPLACEMENT OF FILTERS
To replace or maintain the filters, simply proceed according to Fig. 2. When the filter
replacement indicator B10 comes on, it indicates the end of the filter service life. The
HEPA filter indicator (marked as FILTER 3 on the display) will come on after 3000 hours
of operation, which corresponds to approximately six months of intensive use - after this
time, the filter needs to be replaced (unless it was replaced earlier due to contamination and
higher dust level in the surroundings). The carbon filter indicator (marked as FILTER 2 on
the display) will come on after 3500 hours of operation and the pre-filter indicator (marked as
FILTER 1 on the display) will come on after 4000 hours of operation. To restart the indication
(once the filter has been replaced), press the button B10 and hold it for several seconds.
Attention
– When the front cover A6 is removed, the purifier will turn off and switch to the standby
mode. When the cover is not fitted properly, the appliance cannot be put into operation .
IV. MAINTENANCE
Maintenance of the purifier includes cleaning the power unit body and replacement of filters.
Power unit
Only clean the power unit body with slightly damped cloth with non-aggressive cleaning
agent added. You may use vacuum cleaner to clean the front part with discharge holes.
Do not allow water to get inside! Let the purifier thoroughly dry out before using it again.
HEPA filter A3
To guarantee proper function and air purification quality, HEPA filter must be replaced in
regular intervals. Never wash the filter to avoid reducing the filtration capacity of the filter;
only knock it out, vacuum or blow it with compressed air – however this will not fully restore
the filtration capacity of the filter.
