8. Maintenance
Maintenance work, including changing/removing filters, may only be carried out by
authorised persons wearing suitable protective clothing.
The appliance must be completely disconnected from the power supply during all repairs
and maintenance work.
We expressly refer to possible additional regional and national regulations in the
maintenance of the appliance technology.
The air-conditioning systems (dust extraction unit, industrial vacuum cleaners and devices
used for venting or negative pressurisation) must be serviced as required, at least once a
year, and checked by a qualified technician. The test result shall be presented on request.
Devices with SRE connect control should be checked and calibrated once a year
by the deconta service.
8.1. Information on filter change
The frequency of the filter change depends on the degree of contamination of the filters.
As the filter occupancy is increased (contamination of the filters), the air performance
decreases.
For filter monitoring during operation, a pressure gauge is attached to the S 50 and S 55.
For the S 200 and S 300, the filter monitoring is shown on the display.
ATTENTION! The device was only tested with original deconta HEPA filters H13 and
original deconta HEPA filters H14. To ensure machine safety, only original deconta
filters should be used. The machine safety cannot be guaranteed if this is not
observed. This may result in the risk of hazardous substances being released into
the environment due to a filter overload (leakage, filter crack, ...) in an unintentional
and uncontrolled manner.
8.1.1. Control SE
The following table shows the display values for a recommended filter change. If the display
exceeds the programmed value, please replace pre- or intermediate filter first. If the display
value drops by 100 Pascal or more, the unit can be operated again. If the value drops less
than 100 pascals, the HEPA filter must be replaced.
