Trim Installation
1) This shower is provided with adjustable wall brackets
for uneven walls. These consist of an Inner
All-thread and a loose Outer Tube. These can be
adjusted to 2-1/2” – 7-1/2” from the wall to the
center of the shower’s vertical riser. Additionally, the
Brackets on the Foot Wash and Upper Risers can
be adjusted to di󰀨erent heights by sliding the bracket
up or down the pipe and locked into place using the
Pipe Stop and Locking Bushing. Use 7mm Hex
Wrench to tighten Locking Bushing.
THESE SHOULD BE INSTALLED AND ADJUSTED
BEFORE INSTALLATION OF THE SHOWER.
(See Fig. B)
2) Install Sliding Bracket onto Upper Riser and secure
into place at desired height. Be Careful not to
damage nish when installing bracket. Install the
Top Riser by applying the provided glue and
threading the male pipe into the Cross or Tee Body.
(See Fig. C)
Note: Make sure glue dries so the Top Riser and/
or Foot Wash are oriented in the correct position. The
threads should be pre-clocked from the factory so this
orientation is correct when fully threaded into the
body. The Pipes are sealed with 2 internal o-rings.
Be careful not to damage when installing the
pipes. Lubricate the inside of the pipes to help.
3) Use Thread Compound or Tape threads for the
Shower Arm and fully thread Shower Arm Into the
Elbow.
(See Fig. D)
Note: Make sure the Shower Arm is oriented in the
correct position. The threads should be pre-clocked
from the factory so this orientation is correct when
fully threaded into the Elbow.

2) Setting Temperature Limit Stops:
There are two Limit Stops included with the cartridge.
The Shut-o󰀨 Limit Stop does not need to be removed
and should remain in the position supplied from the
factory. The cartridge should not supply any water
when in this position.
The Hot Limit Stop will need to be adjusted so the max-
imum temperature of the mixed water is in accordance
with your local plumbing codes and standards.
a) Using a thermometer to measure the mixed water
temperature, adjust the Hot Limit Stop to desired
maximum hot water temperature.
Increase water temperature: Rotate Hot Limit Stop
clockwise on the stem.
Decrease water temperature: Rotate Hot Limit Stop
counter-clockwise on the stem.
(See Fig. H)

dangerous and may cause scalding, server injury
or death. This valve is NOT factory preset. Installer
