Install the rough so that the outside surface of the
finished wall falls between the “minimum” and
“maximum” lines on the installation box (i-box).
This will insure that the trim fits correctly.
The i-box must remain on the
valve.
Flush the supplies using the flushing
plug
The i-box incorporates a flushing plug to permit
line flushing and pressure testing before the car-
tridge and trim are installed.
A pressure test of the piping should be performed
before the walls are closed.
The flushing plug permits hot water to flow through
outlets I & II and the cold water to flow through
outlet III.
Install hose bibbs and hoses to the outlets. Flush
the lines for at least 5 minutes. Use the hoses
to direct the water to a location where it will not
cause damage.
The flushing plug prevents cross flow. However, it
will not stop the flow of water through the outlets.
If the building is to be pressurized prior to instal-
lation of the cartridge, close the stops or plug the
outlets.
Install the wall material up to the i-box. When the
trim is installed, the i-box will be trimmed nearly
flush with the finished wall, and sealed to provide
protection against water damage.
