INSTALLATION INSTRUCTIONS
821 Series Shower Drain
For a wood subfl oor installation cut a 4.5” diameter hole in the center of the shower fl oor where the drain will be positioned.
Disassemble the shower drain. Put the shower drain base in the opening so the fl ange of the drain base rests on top of the subfl oor.
Solvent weld the drain pipe into the drain base using the appropriate solvent cement.
Before applying the primary mortar bed, cover the drain base opening to keep debris from entering the drain. Apply primary mortar
bed over the subfl oor at 1/4” per foot slope from the wall framing to the top of, but not over, the fl ange of the drain base. Take care
not to let mortar harden on the surface of the fl ange or in the fl ange groove.
NOTE: The sloped mortar bed should be fl ush with the fl ange of the drain base as shown.
When the primary mortar bed has cured, install the waterproof pan liner in the shower area according to the pan liner manufacturer’s
recommendations.
Very carefully cut out the center of the pan liner in the center of the drain base approximately ¼” inside the opening. Cut around
the bolt holes on the drain base to allow for insertion of the bolts. NOTE: Cut outs should be made as minimal as possible around
bolt holes just enough to start the bolts. DO NOT cut close to the fl ange groove. Screw the clamping ring bolts into the bolt holes
approximately 2-3 threads deep. Place clamping collar over the bolts and twist into place making sure the pan liner remains fl ush
to the fl ange. The clamping collar and fl ange are designed to mate together to form the seal with the pan liner. No adhesive is
necessary. Tighten bolts to fi nish the seal.
Finish installing pan liner according to manufacturer’s recommendations. Test the pan liner by temporarily plugging the drain pipe
and fi lling the shower fl oor with water. Once tested, drain the water by removing the test plug. NOTE: Make sure the drain is
connected to the plumbing system.
Screw the head adapter (contains the strainer) of the drain into the clamping collar to the desired height. NOTE: Consider the
thickness of the fl oor tile, and set height of the head adapter so there will be at least 1” of mortar around the top housing. Before the
application of the secondary mortar bed place some pea gravel over the weep holes so the mortar doesn’t completely cover them.
After the secondary mortar bed has set, proceed with installation of shower fl oor tile
