Installation (Horizontal)

• Attaching Foam Weather Seals

  Cut the mounting plate insulation to the chassis length and insert it on both sides of the mounting plate. (Attaching the foam weather seals to the panel assembly rather than the window sash and frame makes for easier cleanup when removing the panel assembly.)

  

  Note

  • Take care not to block drain holes in the exterior sill. If necessary, cut slots in the foam seal to allow any moisture to drain out the window sill drains.

• Inserting Panel Assembly

  Insert the panel assembly in the bottom sash channel as in step 2. Use care when installing the assembly, which will now fit very tightly in the opening. Close the sash tightly against the top of the panel assembly. For a tighter seal, use "no residue" duct tape (not included) to seal any gaps around the installed panel assembly.

  • If needed, install the included security bracket with a bracket screws.

• Sealing Gap between Sashes

  Measure and cut the included window gap insulation to fit the window opening. Stuff it between the window sashes to prevent air and insects from getting into the room.

  Tip

  • For a tighter seal, use “no residue” duct tape to seal the gap between the sashes.

• Connecting Vent Hose

  Align the tabs on the diffuser end of the vent hose to the slots in the panel assembly opening. Insert the diffuser and push it in the Lock direction to assemble with the mounting plate.

  • If disconnected, reconnect the other end of the vent hose to the product by inserting the vent hose into the product with the mounting ring facing out. If the hose doesn’t snap into place, rotate it slightly so the 2 lines at the front align.

• Positioning Vent Hose

  For best results, keep the vent hose as short and straight as possible. However, shape the diffuser end of the vent hose into an inverted U shape just inside the window to allow any rain or condensation to drain out the window.
