When finishing the wall, install the wall material up to the oval installation box.
Do not remove the installation box.
When the trim is installed, the plaster shield portion of the installation box will be trimmed nearly flush to the wall and sealed to provide protection against water damage.
Flush the supply lines using the flushing plug
The installation box includes a flushing plug to permit line flushing and pressure testing before the cartridge and finishing parts are installed. A pressure test of the installed piping should be per- formed before the walls are closed.
The flushing plug permits cold water to flow from the bottom outlet and the hot water through the top outlet.
To flush the lines, install a hose bibb and hose to each outlet line. (Using a hose will permit the water to be directed to a location where it will not cause damage.) Flush the lines for at least 5 minutes.
The porting in the flushing plug prevents cross flow. However, it does not stop the flow of water through the outlets.
