7.3.1 Filter replacement
In case of reduced air flow of the unit heater its filter should be inspected and, if nec-
essary, replaced or cleaned.
If the filter assembly of the unit is fitted with a differential pressure switch, the relevant
value must be set (not performed by the factory). A signal lamp on the OSHE control
cabinet is used to indicate if the filter needs to be replaced.
Use the type code on page 3 for ordering a spare filter.
