Installation instructions – Double hung window
Remove the window screen
This fan will extend beyond the window screen. Remove the window screen. The unit will be
sealed in the installation process. The unit also has a filter that will block insects and bugs so a
screen is not necessary with this unit.
Install the bottom and side weather strip
Place 4 glue squares on the bottom window sill where EcoBreeze 2.1 will be placed. Cut the 52”
weather strip to the window width. Attach the weather strip to the bottom window sill. Place 2
glue squares on each side of the window. Cut 2 pieces from the 52” weather strip the height of the unit and install the
weather strip.
Install the support bracket
Install the support bracket. Place it in the center of the window and snug it up until it is
approximately level. Remove from the window. Install one wide glue adhesive on the vertical
windowsill face and the other on the vertical outside wall face. Place the bracket in the window
and press it in place. Screws (user provided) may be used to secure the bracket to the sill and
outside wall.
Install the extenders
Remove the 2 end screws from the window bracket. Loosen the center screw. Insert the extenders
into the window bracket and secure with the 2 end screws. Tighten the middle screw. Note: for
windows that are between 20” and 22” use only one extender.
Install EcoBreeze 2.1 in the window
Place EcoBreeze 2.1 so it is centered in the window. Slide the extenders to the window frame and into
the window channel.
Install the extender foam panels
Measure the opening in the extender. With scissors cut the foam insulation
panel approximately 1/8” larger for a snug fit. Slide foam in slot.
Install the top weather strip
Place 2 glue squares on the top of the unit and 2 on the end of the extenders.
Cut the 42” weather strip to the window width. Attach the weather strip to the
unit.
Close the window
Close the window so the window frame is between the window bracket and the motor dome. For a
secure installation a window lock can be purchased at home centers or hardware stores and installed
on the window.
Install the center sash insulation
Cut the center sash insulation to the window width. Loop wire tie around insulation for easy removal. Insert it in the gap
between the top windowpane and the lower window frame with the stiff insulation facing indoors. For some windows
with a narrow opening the insulation may be need to be smaller. Cut the insulation along the width on the softer
insulation side using scissors and install.
Enjoy Nature’s summer cooling!
