Installation Guide

Frequently Asked Questions
Q: How do I clean my FAN?
A: It’s important to clean the GRILLE cover from time to time. Dust particles can
build up on the GRILLE. See PAGE 19 for care and cleaning instructions.
Q: What is CFM?
A: CFM is a measurement of air movement (cubic feet per minute). The higher the
CFM, the more air movement.
Q: What is a Sone?
A: Sone is the rating used to describe the sound level. The lower the Sone the
quieter the fan.
Q: Can I install my bathroom ventilation FAN directly over a bathtub or shower?
A: Yes, but your FAN must be on a GFCI protected breaker. You must also use or
consult a qualified licensed electrician.
Q: Do I have to vent my FAN to the outside?
A: Yes. All spot ventilation fans must be vented to the outside. Follow your local
code and consult it for advice. See PAGE 6 for national venting installation
suggestions and guidelines.
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 6) 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 19) or check for
obstructions in ductwork. A common problem is debris in the roof cap.
Q: Why is there water dripping from my 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 19 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 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!
