Filters Replacement

Dif -Pur models have a visual indicator of dirty f ilter alarm. When

the LED lights up, the two f ilters need to b e changed.

Even if the dirty f ilter signal is not turned on, it is highly

recommended to replace the f ilters every 500 hours in the case of

the G4 and every 3,000 hours f or the HEPA f ilter.

For the replacement of the absolute f ilter, the inlet grille must f irst

be removed and then the f our wing nuts that press the f ilter

loosen.

Finally, remove the dirty f ilter and place the new one by f ollowing

the steps in reverse order.

In the case of the pref ilter it is not necessary to remove the inlet grille since the f ilter is located on top of the

equipment. Just loosen the two wing nuts that keep it f ixed to the equipment and remove the dirty f ilter.

To assemble, place the f ilter clean and tighten the wing nuts to prevent it f rom moving or entering air without

passing through the f ilter.

Bef ore changing any f an or f ans, it is mandatory to advise and indicate that work is under way on the

equipment, disconnect the power f rom the current and make sure that there is no voltage and that the f ans

have stopped.
