Pre-Installation (continued)
IMPORTANT: Please read before attempting installation.
The fan and shutter are designed for horizontal installation only. The louvers will not function in the vertical position.
The wooden fan frame is installed on top of the joists, and the shutters open up between the joists. Therefore, the rough opening will be
smaller than the fan frame size.
DO NOT OVERSIZE YOUR FAN! Additional installation of exterior vents may be required to provide sufcient Net Free Exhaust Area (NFA)
for your fan to operate safely and effectively. Remember, bigger is not always better with whole house fans. A smaller fan that operates
efciently is always preferable to a fan that is too big for its application.
Veins run lengthwise in 24-in. and 30-in. shutters. The center vein is stationary to allow for no-cut joist installation.
When measuring vents for NFA, remember that louvers and screens cut down considerably on the available free air. This can be factored in
by measuring the length by the width of the open vent area and dividing the resulting surface size in half.
Model Number Fan Size Shutter Rough Opening

DECIDING ON A JOIST-IN OR JOIST-OUT INSTALLATION
Joist-in
The ceiling joists will be left intact for this method. You will need another attic access, as the fan will not t through the shutter opening
with the joist(s) in place.
Joist-out
This method involves removing one or more ceiling joists. This is the preferred method, as the best location does not necessarily coincide
with the position of the joists.

Installation - Joist-in
1 Preparing the shutter opening
□Find a spot in the center of the hallway, drill a hole and
feed a wire through to mark it.
□Mark space around the wire equal to the area of the rough
shutter opening in the table on page 5 in the joist-in option.
□Remove all insulation above the installation site.
□Align the shutter vein with the ceiling joist in the center of
the shutter opening.
□Draw a line on the ceiling marking the rough opening size
of the shutter frame.
□Double-check the accuracy of the dimensions you have
marked and ensure that all the corners are square.
TIP: Use the shutter as a template to outline the opening by drawing
the cutout line around the inside edges.
2 Cutting the shutter opening
□Cut through the ceiling along the lines using a circular saw.
Measure the depth of the drywall and adjust the saw so
you only cut the drywall and avoid the joists.
□Carefully remove the drywall from the opening.
NOTE: Make sure the exposed joist is centered.
3 Framing the shutter opening
□Use lumber of the same dimensions as your ceiling joists
and fasten the boards to the edges of the frame opening
using #12D nails.
□Fasten the sheetrock to the new frame using 1-1/2 in. ring
shank drywall nails.
□Seal any gaps between headers and joists with caulk or
foam insulation.
4 Installing the facing
□Use 2 X 6 boards to create a square with the inside
dimensions being the same distance as the shortest
dimension of the shutter rough opening (i.e., 26 in. for a
24-in. model, etc.).
□Nail or screw in the facing to the framed opening.
TIP: For a quieter fan, build a second box frame the same size as the fan
frame and install it between the frame and facing. Ensure that there is
still a minimum of 36 in. clearance between the fan blades and attic roof.

Operation
Whole House Fans cool your home by pulling in fresh, cooler air from outside through open windows and doors. For the best operation and
most efcient cooling in a multi-story home, open windows on alternate levels.
CAUTION: NEVER operate the fan without open windows or
doors.
CAUTION: If your home has a replace, be sure that the ue
damper is closed to prevent chimney soot from being drawn
into the house by the fan. DO NOT operate the fan when a re is
burning in the replace.
Maintenance
WARNING: Disconnect the power before performing any
maintenance.
□Check all electrical connections annually.
□Ensure that the housing is unobstructed and is free of debris to allow proper air ow.
□Check the belt tension (belt drive unit only).
Care and Cleaning
WARNING: Disconnect the power before performing any
cleaning.
□Wipe down the unit with a damp cloth or rag.
□Do not use corrosive or harsh chemicals to clean.

Troubleshooting
Problem Solution
The fan will not turn on. □Ensure that there is a proper electrical connection.
□Check the breaker in the main fuse panel.
□Ensure that the belt is intact and/or installed (CX30BD-2SPDEVB belt-drive unit only).
The fan will not turn off. □Ensure that there is a proper electrical connection.
There is a loud noise coming
from the unit.
□Ensure that there are no obstructions or debris caught in the housing.
□Ensure that the unit is securely fastened to its mounting surface.
□Try to identify whether the noise is coming from the motor. If it is, it is possibly a bearing issue.
□Check for any loose screws or hardware.
□Open one or more additional windows to ensure adequate air ow.
□If the unit is too noisy in general, install the additional frame between the fan and mounting frame.
□Large fans make noise while operating. Moving the fan further into the attic will reduce the apparent
noise. Make sure you still have 36 in. of clearance to the roof.
□Make sure all screws and bolts are tightened.
□Ensure that there is enough clearance above the unit, minimum of 36 in. from fan blades to roof.
□Verify the exhaust Net Free Air (NFA). Inadequate NFA will result in the unit working harder and
making more noise.
The motor stops after 10 to 20
minutes.
□Tight belt tension can cause the unit to overheat.
□There is insufcient intake or exhaust of NFA. Open more doors and windows or increase the amount
of ventilation in the attic.
□Check the bearing assembly for resistance on belt-driven models to ensure there are no rough spots.
There is not enough air ow. □Verify that NFA intake and exhaust requirements are being met. Lack of airow can be the result of
lack of fresh air and lack of ventilation to expel the air. Try channeling the air by opening only doors
and windows in a certain area to funnel the wind ow.
The shutter is hitting the fan. □Check to make sure there is enough space between the louvers and the fan. There should be around 6
to 7-1/2 in. between the fan blade and the vent.
The fan does not start on low
speed.
□Verify that the fan will start on high speed. Switch to low speed from the high setting. For additional
troubleshooting, please contact our customer support team.
