WV410 WINDOW - INSTALLATION INSTRUCTIONS
Section VIII – Window Installation
C. Ribbon Window Installation
Step 8
Install the next WV410 frame by aligning the interlock of the window with the mullion interlock.
Step 9
Shim the WV410 frame into the correct location and anchor to the opening at the top, bottom,
and mullion side at the recommended locations covered in Steps 2 through 3 on Pages 16 and 17.
Step 11
After the WV410 frames and intermediate mullions have been installed, the interior and exterior
perimeter seals are to be applied. Seal the interior joint between the vertical frame and the
storefront opening at the top, bottom, and end jambs of the ribbon run. The vertical mullion
required no additional sealant at the interior surface. The exterior joint between the WV410
frame, storefront opening, and the intermediate vertical requires a continuous seal at all four (4)
sides of the WV410 frames. See Figure 21 on Page 16 and Figure 23 below.
Step12
If your application includes projected vents only, the operable vent may now be installed. See
section IX on page 20. Casement vents must first have the lift blocks installed. See Section VIII
on Page 19 for installation. Reinstall the operable vent to the WV410 frame. Be sure to mount
the vent and hinges in the same locations preinstalled by EFCO.
