Installation Guide
Installation
1. Position valve body in wall. It is recommended the valve to be about 48” above the oor and shower
outlet to be about 30” above the valve (Fig. A1) The nished wall should be set between the markers on
the temporary protective cover. The recommended depth is 2 11/16” to 3 7/16”. (Fig. A) Make sure the
UP outlet is pointed upward. (Fig. B)
NOTE: Valve access hole on the wall should be 6” in diameter and outlet hole for shower arm is about 1
1/4” in diameter.
2. Connect the valve to the plumbing with proper ttings. Perform a dry t before soldering pipes to the
valve. (Fig. C)
WARNING: Exposure to high temperature will damage the cartridge (9) and stop valves (7, 8). Remove
these parts before soldering.

3. After the pipes are soldered, install the stop valves (7, 8), cartridge (9), stem (11), and threaded
nipple (12) back onto the valve body.
4. Pressure test and ush the valve. NOTE: Pressure must be approximately equal on both hot and cold
side for the valve to function properly. (Fig. D)
• Install a 1/2” iron pipe plug (not included) on the shower outlet.
• Turn the valve to ON position and check all connections for leaks for about a minute.
• Turn the valve to OFF position after pressure test. Make sure the pipes are free of debris or
sediments and remove the 1/2” plug.

7. Re-install the threaded nipple (12) and stem (11) assembly to the valve body. Carefully slide the
escutchron plate onto the valve and attach the handle assembely shown in gure G.
8. Slide the ange (3) onto the shower arm (2) and apply PTFE tape to both ends of the shower arm.
Attach the shower arm to the plumbing and slide the ange on the wall. Attach the shower head (1) as
shown in Fig. H. (NOTE: Do not over tighten the connections.) The installation is now complete.
5. Remove and discard the protective sleeve (15) and cover (13) from the valve. Slide the escutcheon
onto the valve. Attach the handle (18) as shown in Fig. E. Place the handle assembly on the stem
extension (12) and turn the handle clockwise to install the handle. If there is a gap when the handle
is attached to the valve measure and write down the distance of the gap between the handle and the
escutcheon plate as shown in Fig. E1.
6. Remove the handle and the escutcheon
plate and set them aside. Remove the
threaded nipple (12) and the stem (11) from
the valve body. Use a hacksaw to trim the
threaded nipple (12) and valve stem (11)
based on the measurement taken in step
5 gure E1 as shown in gure F. (NOTE:
Trim the pieces separately, do not trim both
parts at the same time. It is best to cut o
only small amount of the brass stem and
test t the handle.) (NOTE: Do not trim the
stem (11) and threaded nipple (12) directly
on the cartridge because it will damage the
cartridge)
