You now want to attach the Drain adapter flange
to the Fusion Pan. First apply a bead of caulk to
the underside of the drain adapter flange. Lightly
push the flange into place, and screw it down
using the four ¾” screws provided. Remove any
excess caulk that squeezes out.

On top of existing subfloor and walls install cement
backerboard in preparation for tiling. Make sure
that the top of the backerboard is roughly 1/8”
higher than the Fusion pan. Start with a bed of
thinset using a 1/4” notched trowel. Next, attach
the first layer of 1/2” backerboard with 1 1/4” cement
board screws 8” on center. Then, making sure to
stagger the joints, attach the second layer of 1/2”
backerboard with 1 5/8” cement board screws 8” on
center. Finally, finish the joints with alkali-resistant
mesh tape.
Step 10
Check that the Fusion Pan is level on all four sides.
Fill in any gaps around the perimeter of the pan over
1/8” with latex or acrylic caulk.
Do not use 100% silicone.
