Filters Replacement
Dif-Pur models have a visual indicator of dirty filter alarm. When
the LED lights up, the two filters need to be changed.
Even if the dirty filter signal is not turned on, it is highly
recommended to replace the filters every 500 hours in the case of
the G4 and every 3,000 hours for the HEPA filter.
For the replacement of the absolute filter, the inlet grille must first
be removed and then the four wing nuts that press the filter
loosen.
Finally, remove the dirty filter and place the new one by following
the steps in reverse order.
In the case of the prefilter it is not necessary to remove the inlet grille since the filter is located on top of the
equipment. Just loosen the two wing nuts that keep it fixed to the equipment and remove the dirty filter.
To assemble, place the filter clean and tighten the wing nuts to prevent it from moving or entering air without
passing through the filter.
Fans Replacement
Before changing any fan or fans, it is mandatory to advise and indicate that work is under way on the
equipment, disconnect the power from the current and make sure that there is no voltage and that the fans
have stopped.
