3.) The right location
We recommend that you place the air purifier under the following aspects:
Central to achieving the highest possible effectiveness.
Near possible sources of dirt (workplaces).
With a clearance of 50 cm on all sides.
With a distance of approx. 100 cm to other electrical appliances and/or machines.
Note:
When large amounts of dust are generated, an air purifier alone may not be
sufficient to ensure high air quality. If necessary, we recommend creating an additional
air exchange by opening windows and doors !
Furthermore, you can connect up to four (4) WDH-AF500B industrial air cleaners to
each other to increase the filter capacity (see picture on the right). To do this, unscrew
the cover and connecting disc of the unit and then connect the units together.
4.) Switching the appliance on and off
First connect the unit properly to the mains socket. Remove the cover plug of the air intake and now turn the
stepless control dial clockwise until your industrial air purifier starts.
Note:
Please note that the industrial air cleaner starts immediately at the highest level. Should you continue to turn
the control dial clockwise, you will increasingly reduce the performance (air flow rate).
5.) Strongest operating level (MAX)
We recommend that you initially run the industrial air purifier at full power to sufficiently clean the affected room or
area. As time goes by, you can decide whether a lower operating level is sufficient for you.
6.) Reset button
Use the reset button in the event of technical difficulties (e.g. motor runs out of round) to disconnect your air purifier
from the power supply in the event of any problems (motor problems) and thus protect it from further damage. The
reset button has no function in normal state/normal operation.
7.) Filter change LED
The filter change indicator shows you when the air flow rate of the unit has decreased considerably due to clogged
filters. Now the coarse dust filter or the HEPA filter in particular should be checked or replaced. The air flow rate is
measured by a differential pressure switch integrated in the unit.
Large amounts of dust can greatly reduce the lifetime of the filters. If necessary, change the filters in case of heavy
soiling even before the filter change indicator lights up.
Hint:
Disconnect the mains plug before cleaning/replacing the filters. For best filtration results, we strongly recommend
that you use only original filters from the manufacturer.
To change the filter, follow the instructions as described earlier in the operating instructions under point 2.).
