Instructions for use

Overview control element:

Preparation and installation of the filters

The air purifier is equipped with a coarse dust filter (G4) and a HEPA filter (H13) from the factory. To install new filters, first open the filter compartment door by opening the locking buckles. Now remove the coarse dust filter and the HEPA filter. Then insert the new filters neatly back into your air purifier. When inserting the HEPA filter, make sure that it is inserted the right way round. (The marking arrow on the filter indicates the direction of the airflow.) Finally, close the filter compartment door again properly using the locking buckles.

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.

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).

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.

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.

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.)

Cleaning & Storage

Always unplug the appliance from the mains before cleaning it !

Cleaning:

Use a soft and damp cloth to clean the outside of the unit.
Only use mild cleaning agents to clean your air purifier.
Please make sure that no water gets into the interior of the appliance or onto the filters at any time !

Storage:

We recommend covering the unit for storage or ideally packing it in its original box.
Store the unit in a dry and sufficiently ventilated place/space.

Troubleshooting

The unit itself emits an unpleasant odour:

A new air purifier still has a slight odour of its own (fresh plastic, new motor, new paint, etc.). This new smell dissipates within a very short time (1-2 weeks) !

The unit does not respond / The unit cannot be switched on:

Check the power cable, especially the connection to the air purifier. Please also check whether the power socket is live and whether the air purifier is switched on.
