Wall Humidity Fan

Some people do not fully appreciate the value of a humidity fan in their home, but you need to consider the fact that when high levels of humidity are present, it will inevitably lead to mold and mildew development. This, in turn, will cause unsightly patches on walls, odors and similar consequences which will cost money to repaint or remove. Hence, it pays to have a humidity fan. Installing a wall humidity fan is not as hard as one might think. All one needs to do is follow a few simple steps.

Step 1: Positioning of the Fan

After deciding the location where your humidity fan is to be installed, position it on the specific wall and trace around it with a marker. You can also make a template by using a piece of cardboard, placing the wall humidity fan on the cardboard and tracing around it with a marker.

Step 2: Drilling Holes

Next, take your driller and drill holes in each corner of the marked outline you drew on the wall. Then, take your coarse saw and start cutting from hole to hole of the marked outline until you end up with a suitable indented form similar in size to your wall humidity fan.

Step 3: Marking the Location For Screws

Locate the interior conduit of the house, which will connect to the ductwork on the outside. Then, mark around it using a faint marker so that when you are installing your wall humidity fan, you will find it much easier, and you will manage to locate the position where you will need to install and wire it. Another alternative is making a template for the outside wall using the fan’s dimensions. Next, you need to place the humidity fan in the hole so you know where the screws need to go. Mark the spots where the screws need to be placed.

Step 4: Drilling Holes For The Exterior Wall Template

Once you have drilled a hole where the screw mark was marked, mount drywall anchors in each of the holes. It is important to drill four holes inside the marked line. These holes are drilled so that it is easier to locate where you’ll line up your wall template later. Once the holes for the exterior template are aligned, trace the template with a marker.

Step 5: Installing the Wall Humidity Fan

After you drill holes in each corner of your template, cut from hole to hole with your saw to make an opening for your damper door housing. Place the fan in the hole and with the fasteners provided, attach the damper door housing. It is important to turn off the power from the main circuit breaker to avoid getting electrocuted. Connect the neutral wire (white) from the power supply feed to the neutral wire on the fan’s motor. Also, connect the hot wire (black) from the power supply to the switch’s black wire with wire nuts. 

Step 6: Finishing Up

Turn the power back on from the main circuit breaker and check whether the humidity fan is working as it should be and its blades are all spinning freely.
