Installation Guide

1. Retrofit/Remodel Installation
CAUTION: Risk of property damage. Water leakage may
occur if supply piping allows movement. Ensure the supply
piping and 1/2″-14 NPT elbow fitting are securely fastened to
braces in the stud framing.
IMPORTANT! Check the existing shower enclosure for adequate
clearances as described in section ″Before You Begin.″
Remove the existing showerhead and shower arm escutcheon.
Carefully push the existing shower arm toward the finished wall
surface.
Check for inward movement of the supply piping.
If inward movement is possible, securely fasten the supply piping
to braces in the stud framing before beginning the shower column
installation.
Remove the existing shower arm.
Measure the existing shower arm hole. Ensure that the finished
wall material has an upper supply connection hole diameter
between 1″ (25 mm) minimum and 1-1/4″ (32 mm) maximum,
and the hole is centered on the outlet of the 1/2″-14 NPT elbow
fitting. Repair the wall surfaces if the existing shower arm hole is
not centered or exceeds the recommended dimensions.
