How do I set up and install the filters before using the HPA090 for the first time?

Before using your new air purifier, you must remove the protective wrappers covering the filters. Make sure the air purifier is OFF and unplugged, then press the two hand symbols on the front grille to release it and pull toward you. Grasp the sides of the filter frame near its top end, pull outward, remove the protective wrap, place the HEPA filter back in with the pull tabs facing outward, place the Pre-Filter on top, and tuck its edges into the tabs to secure it. Replace the front grille by inserting the bottom tabs into the slots and pressing the hand symbols to secure it in place. (Page 2)
