						Screw in lower part using an Allen® wrench.
						Insert filter.
						Place cap over filter onto lower part. The recesses of the lower part allow assembly of the cap in the proper and accurate position.
						Ventilation / open position: Turn cap clockwise (CLOSE arrow) up to the first indexing position. Marker 1 is located above the reference pointer. The indexing mechanism prevents the cap from inadvertently loosening.
						Closed position: Continue to turn the cap clockwise (CLOSE arrow) until marker 0 is located above the reference pointer. Also in this position, an indexing mechanism prevents inadvertently loosening.
						To return to the ventilation / open position, to change the filter or to disassemble the unit, turn the cap counter-clockwise indicated by the OPEN arrow.
