2.4 INSTALLING THE RM WHF-4.0-DG2
Use the following instructions to finish the installation of your accessory kit.
These instructions are for installing the RM WHF-4.0 with (2) 16” x 16” damper grilles.
1. Using a stud finder, find and measure your ceiling joists and determine the location for your
damper grilles. Make sure the fan is equally centered between the two damper grille locations.
Make sure the damper grilles are installed in the same joist bay as the fan.
2. When you have chosen your exact spot, place the provided template on the spot and make sure
that you have at least 2 inches of clearance all around it. While holding the template in place, mark
its outline with a pencil.
(See Figure 2.4A)
3. Using a drywall saw or similar device, cut out the hole in the ceiling.
(See Figure 2.4B)
4. Remove the damper grille and screws from its packaging. Place the grille in the ceiling cutout.
Install the grille with the white screws provided by screwing through the drywall.
(See Figure 2.4C)
5. Repeat steps 2 through 4 for the second damper grille.
