Figure 11 - Display on the filtration unit
The keypads (1), (2) and (3) are locked in normal operation and are only to be used under
certain conditions.
The display (A) shows the total running time of the filtration unit so far. Under certain
circumstances, the volumetric flow rate is briefly displayed here in percent, e.g. when
lowering the power to standby mode. (B) visualises the filter cube, (C) the fan in operation.
In case of a blockage of the filter, the necessary inflow velocity can no longer be ensured and
the alarm signal sounds. In addition, a visual alarm is shown on the display on top of the
enclosure. For further information on how to behave in the event of malfunction, please refer
to the chapter "Behaviour in case of malfunction".
Filter change (only by qualified personnel)
Opening and changing the filters must only be carried out by appropriately qualified
personnel (e.g. a1-envirosciences). A DOP test (Dispersed Oil Particulate) must be carried out
after changing the filter.
