1. Flush all piping thoroughly before installing.

2. Position mixer 2–1/2

″ from center line of inlets to face of

finished wall. Facing front of mixer, connect hot water to
left side, and cold water to right side. Inlet connections
must be piped correctly for proper operation of Mixer.
Connect hot water inlet to side labeled “H” on bonnet
label, or “HOT” on port label.

3.

Single Outlet Model can be top or bottom mounted.
See Figures 1 and 2. Unit is factory assembled for top
outlet installation. For shower use only, pipe top outlet

directly to shower head. If bottom outlet is required (or
revered inlets), place mixer stem in closed position (full
clockwise) and remove O-ring and Stop (Figure 7). Rotate
stem 180° and replace Stop in its initial position. The let­ter “C” (stamped on side of stem, Figure 3) must face the
cold water inlet when mixer is shut off. Hot and cold
inlets should also be identified to avoid confusion during
future maintenance.

4. Installation should be in accord with accepted plumbing
practices.

5. Double Outlet Model. See Figure 4. The top outlet “S”

is piped to the shower head. The bottom outlet “Tub” is
piped directly to P diverter type spout, There is a built­in diverter fitting in the Mixer so it is not necessary to
use a twin ell. Be sure that “Tub ” is piped to the tub. If
the outlet connections are crossed, the Mixer will not
function properly.

6. Side Roughing-in guide onto mixer stem until it contacts
temperature stop on stem facing front of mixer, the
words “FRONT FINISHED WALL GUIDE” can be read.
Position mixer so finished wall surface will be within the
3/4

″ rim on the guide. This insures the center line of the

mixer connections will be 2-1/2 inches (64 mm) from the
finished wall surface. After wall is finished, remove guide.
