Installation
Inline Media Air Filter
This ventilator includes a high efficiency MERV 16 inline media air
filter which helps remove airborne particulates from the intake air.
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 ex-
hausted 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.

Completing the Installation
NOTE: This unit is equipped with a wire mesh insect screen.
Confirm that the screen is installed inside the control compartment
just inside the intake port. Position the screen with its stamped
depression towards the controller.
1. If, when the ventilator is unpacked, the insect screen is not in
place, remove the Control Compartment cover (Figure 7) and
insert the screen behind the tab at the base of the unit. Make
sure the wider side of the screen is running side to side inside
the unit (Figure 10).
2. Slide the screen to the side of the cabinet with the larger top tab
making sure the screen fits behind the tab (Figure 10).

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.

Configuring the Controller
The controller mounted inside the ventilator monitors the
temperature and humidity of the incoming air. The installer of
this ventilator can configure this controller to suit the ventilation
requirements of the home. Before configuring the controller,
remove the protective plastic film from the controller's LCD screen.
With power to the ventilator turned on, the initial screen will
show OFF. Press the ON button to show the current temperature
and relative humidity. By pressing the ON button, the ventilator
will initially turn on for continuous airflow of 30 CFM which is the
factory default setting.
Energy Saving Mode
NOTE: This ventilator is equipped with an Energy Saving Mode
that allows upper and lower limits to be set for both temperature
and humidity. Setting these limits will help prevent large swings
in temperature or humidity caused by extreme conditions of
the outdoor air entering the home. This will also help to reduce
unnecessary energy consumption and improve occupant comfort.
