This filter has nominal dimensions of 10" x 10" x 2" with actual dimensions of 9.5" x 9.5" x 1-11/16". NOTE: Inserting this filter in the airflow path decreases the airflow delivered by the unit. And flowrate is further decreased as the filter traps particles from the incoming air. As a result, the filter must be changed periodically to avoid excessive reduction in flowrate. In certain installations, the MERV 16 filter may be found to be too restrictive, reducing the airflow too much. In those cases, a replacement MERV 13 filter part number DQ-P-F-13 should be considered. Installing or Changing the Air Filter: 1. Remove the two screws securing the control compartment cover and remove the cover to gain access to the controls and filter area (Figure 7). 2. Pull out the exhausted filter from the Control Compartment and place in the garbage. 3. Insert a new filter into the slot in the housing where the exhausted filter was installed. Make sure the filter is seated all the way to the bottom of the housing (Figure 9). 4. Close the control compartment cover and reinstall the screws holding it in place. 3. Then slide the screen in the opposite direction and tuck it behind the smaller tab (Figure 11). 4. Confirm that the screen is being held in place by both top tabs (Figure 11). 5. Reinstall the control compartment cover and the screws to hold it in place. 6. Restore power to the ventilator and test your installation.
