Loosely insert the Alignment Ring 1 into the Drain Unit opening with printed side up. Align the notch in Alignment Ring 1 with the arrow printed on the Drain Unit. Alignment Ring 1 has a threaded inside which will later allow you to insert a Drain Cover Extension, which will allow you to laterally and vertically move your drain cover for perfect alignment with the tile finish. Alignment Ring 1 is also needed to support the drain cover unit when no Drain Cover Extension is used. Alignment Ring 1 has built in drainage slits to allow the tile adhesive around the drain area to drain water more quickly.

Insert the Snap Ring 2 into Drain Unit opening with printed side up. Align its arrow and protruding key fitting into the notch of the Alignment Ring 1. The Snap Ring 2 needs to be secured in place with its perimeter notches snapping into grooves which are premade in the Drain Unit. Snap Ring 2 is used to secure the movable Alignment Ring 1, and it is needed to later support the Drain Cover unit. It is equipped with drainage slits to allow tile adhesive around the drain area to drain water more quickly.

Optionally, use and insert the threaded Drain Cover Extension into the threaded part of the Alignment Ring 1. Dry fit the Drain Cover Extension for the needed final height position of the drain cover unit. The Drain Cover Extension only works for wedi’s finished surface drain covers, but not with wedi’s tileable covers due to their special water drainage design.

Dry-fit a tile for the shower base right next to the extended drain cover unit and determine to what height the Drain Cover Extension may need to be cut down for a drain cover top flush with the top of the tile (or drain cover top slightly below top of tile). Account for the thickness of the (compressed) tile adhesive used to install the tile.

The Drain Cover Extension can be cut to height/length at its threaded part using a fine tooth saw for a fast, clean and safe process. Make cut within one groove between threads. Please note, the threaded connection also allows for some adjustment after cuts are made. The Drain Cover Extension should connect to the threaded Alignment Ring safely and for good support, which requires at least one full turn of the extension‘s male threads reaching into the Alignment Ring 1’s female threaded part. The extension can be used to increase the position of the drain cover by 1 ¼ in.

Place the drain cover unit loosely on the Drain Cover Extension were it fits into a tight seat. The cover is now vertically adjustable and can also move horizontally to fit the tile layout.

The drain cover unit can still be moved laterally 3/16 in. in either direction, and can be aligned with the tile.
