WE RECOMMEND KEEPING YOUR WINDOW SCREEN IN PLACE
INSTALLATION INSTRUCTIONS:
This window fan has been designed to fit double-hung, slider and casement windows with minimum openings of 24” wide and 14.5” high. For
casement windows, please see above, right column for information on
available bracket. This fan is designed and recommended for used with
your window screen in place.
For double-hung and slider windows:
NOTE: On SLIDER WINDOWS the bottom section must be the side you
add extenders to (left side). The controls should be facing toward the
window.
1. With the window open, take an accurate measurement of the opening where the unit will be placed.
2. Match your window measurement with the installation guide (see
figure #2 text); adding the appropriate extender panel(s) to
the left side, while using the

fan in the window, and complete the installation process
using the built-in extender.
Pull out for a snug, safe fit
(see step 5)
4. Carefully close the window onto
the top of the fan so that the
bottom edge of the window
rests behind top line of fan
housing. This is important as
it aides in keeping the fan in
place.
5. Lastly, pull out the built-in extender on right side to fill in the
remaining space. To pull out, simply pop up the extender lock
on the top of the fan housing next to the built-in extender, and
set to the desired length. To secure in place, push the extender
lock back down.
Casement Windows:
For a safe, secure fit in your casement window, you will need a special
bracket system. For easier installation in a casement window, we will
provide you with two brackets and screws at no additional cost. Please

OPERATING INSTRUCTIONS:
• Make sure rotary switches are in the OFF position.
• Plug into 120V AC electric outlet.
• Set the individual fan motors on either INTAKE or EXHAUST using
the control lever.
• To start the unit, turn the rotary switches to desired speed (HI, MED,
LO, SLEEP). Note: • If unit will not start, please check that Comfort
Control Thermostat is set to HI/largest dot. (Figure 3)
• When operating both fans on EXHAUST, set the Comfort Control
Thermostat all the way to high by turning the dial to the right
toward the largest dot.
• To start oscillation, simply move the Oscillation Switch to the ON
position. The oscillation system is powered by its own separate
motor; therefore, both fans will oscillate when the feature is turned
ON (you can set each individual fan to any speed you desire, including OFF, and both fans will oscillate.) To end oscillation, move the
switch to the OFF position.
Note: Remember to turn the oscillation switch to OFF when fan is not in use.
