Q: Why do the windows and mirrors fog even when the fan is running?
A: If windows and mirrors are very cold, condensation can still form on those
surfaces. If the bathroom is sealed tightly, replacement air may not be entering the
room fast enough to displace moist air. You need a gap under the bathroom
entrance door to allow air to enter the bathroom. Fan placement may also be a
factor. Additionally, your vent pipe must be a short run (see PAGE 5) and vented to
the outside. Lastly, check to see if your vent pipe is blocked; if it is, the fan cannot
push air outside to dry the room.
Q: My fan is operating, but the air is moving slower than normal?
A: Check the GRILLE for buildup and clean if needed (see PAGE 13) or check for
obstructions in ductwork. A common problem is debris in the roof cap.
Q: Why is there water dripping from my fan GRILLE?
A: Dripping water is either condensation (usually due to cold ductwork or improper
duct installation), or a problem with the seal on the roof vent. Insulating the
ductwork and fan HOUSING can help solve condensation problems. Running the
fan longer will ensure moisture is completely removed from the duct.
Q: My fan sounds louder than normal, what’s going on?
A: Most likely, either the GRILLE is vibrating or it needs to be cleaned. See
PAGE 13 for cleaning instructions. To check the GRILLE for vibration: Sometimes
simply moving the GRILLE or taking it off and putting it back on will solve this issue.
Q: My fan will not work, what do I do?
A.) First, check the power. Is the breaker on? Having no power is the most common
reason why the fan or CONTROL will stop working. Next, check to make sure the
wiring is correct, this is the second most common reason why the fan won’t work.
Be safe, consult a qualified licensed electrician!
(Control)
Q: I only have two black wires, how do I properly connect the CONTROL?
A: One of those wires is incoming power and one is power to the fan. Please refer
to PAGES 14-15 for instructions on how to properly wire the CONTROL.
Q: I don’t have a white neutral wire, will the CONTROL still work without it?
A: The CONTROL does need a white neutral to operate. Generally there will be a
type of neutral wire available in your junction box (wall box). Older homes or homes
where code was not followed can make it a problem to find a neutral. If that’s the
case for you, then you’ll need a good level of electrical knowledge and an electrical
testing device to find a neutral wire. We strongly suggest you use a qualified
licensed electrician to do this work.
Q: How do I set the CONTROL's sensitivity for my specific bathroom?
A: See PAGES 16-17 for instructions on how to do this.
Q: The fan comes on too early or too frequently, how can I fix this?
A: This means the CONTROL is set to a higher sensitivity level. Simply turn the
sensitivity dial counterclockwise slightly to reduce sensitivity. We suggest small
increments at a time. See PAGES 16-17 for more details.
Q: The fan doesn't come on soon enough, or there’s already condensation on the
walls by the time the fan comes on, how do I fix this?
A: If you want the CONTROL to come on faster, you can rotate the sensitivity dial
clockwise to make the CONTROL more sensitive. Move dial in small increments
until you find the right setting. See PAGES 16-17 for more details.
Q: I occasionally like to steam up my bathroom, is it possible to disable the
CONDENSATION SENSOR?
A: Yes! To disable the CONDENSATION SENSOR, first make sure the fan is off,
then push down and hold the button on the CONTROL, releasing the button after
15 seconds. To enable the sensor again, simply repeat the process.
