STEP 6) INSTALLING SUBSEQUENT SCREW SPLINE
MODULES
Make sure that the anchors are installed into the head and jamb of the
first module as specified in figures 34-37 on page 26 and 27. The 795
sealant should be applied to the mullion and to the subsill as specified in
figure 31 on page 25 and in figures 38 and 39 on page 28. Place the
second module on the subsill at an approximate 30 degree angle. Rotate
the module into the condition approximately 1/4" away from the
previously installed module. Once the second module is in place 1/4"
from the first module, slide it into position and begin snapping the mullion
halves together. When the two mullion halves are fully snapped, press
the second mullion down onto the subsill to make the sill flush with the
top of the subsill as shown in figure 32 on page 25. See figures 42 and
43 on page 30 for mullion snap fit instructions.
