How to install Cell-Cast Disc?
Step 1: Locate centerline where the hole is desired. This location will be used as a guide where the threaded centering rod will be placed.
Step 2: A 2×4 (48 x 95 mm) wood nailer is included. Fasten it along with the threaded rod directly to the inner face of the formwork. This provides support and helps center the complete Cell-Cast® Disc assembly.
Step 3: Slide the first Cell-Cast® Disc over the *threaded rod. Note: Use only 1 threaded rod for equal distribution. More than one rod could take disks out of shape.
Step 4: Secure the edges of the cell to the form using the provided steel spikes.
Step 5: Additional discs are interlocked to accommodate finished wall thickness. Verify thickness is the same as the wall.
Step 6: Guide the 1” (25 mm) wood block over the threaded rod and secure the assembly with the wing nut provided.
Step 7: Wrap each seam with one wrap of 2” (48 mm) wide tape to bridge any possible gaps. Note: Tape not included. Finish installing concrete forms and pour concrete.
Step 8: After wall cures, remove the formwork. The Cell-Cast® Disc assembly is now ready for removal.
Step 9: Chip excess concrete from the edge of the Cell-Cast® Disc assembly and wall.
Step 10: Remove discs by breaking or cutting out the entire Cell-Cast® Disc assembly.
Step 11: Inspect the installation. A smooth opening is important for a proper Link-Seal® Mechanical Seal installation. Repair voids and grind smooth any ridges.
