Notice to the Installer
• Read this entire instruction sheet before installing to ensure proper installation.
• Installation must comply with local codes and ordinances.
• Do not use pipe dope.
• Care shall be exercised when installing the device to prevent marring the exposed, decorative surfaces.
The supply piping to these devices shall be securely anchored to the building structure to prevent installed device from
unnecessary movement when operated by the user.
NOTE: The information in this manual is subject to change without notice.
Installation may be performed at different times of construction by different individuals.
For this reason, these instructions should be left on-site with the facility or maintenance manager.
NOTE: Installation should be in accordance with accepted plumbing practices. Flush all piping thoroughly before installation.

NOTE: This valve for use with shower heads rated at 1.5 GPM (5.7 L/min) or higher.
All 1905-CP and 1907-CP combination mixing valves meet above performance
specifications based on typical operating conditions as stated in ASSE 1016 (45 psi
pressure differential, hot water supply between 140°-180°F (60°-82°C), cold water
supply less than 70°F (21°C). If your operating conditions vary from those stated in
the standard, performance may vary as well. Consult your local sales representative
or a Chicago Faucet Representative to discuss your specific application. All Chicago
Faucets thermostatic mixing valves perform to the requirements of standards ASSE
1016 / ASME A112.1016 / CSA B125.16 and ASME A112.18.1 / CSA B125.1.
To Install
1. Position mixer 1-15/16˝ ± 1/2˝ [49mm ± 13mm] from inlet center to finished wall surface. The tub outlet port is marked “TUB” and should face down. Facing front of mixer, connect hot water to left
side and connect cold water to right side. The valve has “C” and “H” cast into the body near the appropriate inlet ports.
2. Valve is factory-set for standard inlets. If
reversed inlets
are required due to back-to-back installation (Cold water supply on the left and Hot water supply on the right), follow instructions a – d below:
a. Connect
cold inlet to hot port
(“H”) and
hot inlet
to
cold port
(“C”).
Note:
Do not turn valve upside down. If valve is upside down, water will not flow properly
through tub spout or showerhead.
b. Turn water off with checkstops, remove bonnet and cartridge.
c. Reinstall cartridge. “H” on the cold side of the valve body and “C” should be on the hot side of the valve body.
d. Reinstall bonnet with high temperature limit stop on it.
Note: Be certain that valve opens in full cold!
e. Hot and Cold inlets should be re-identified for reversed inlets to avoid confusion during future maintenance.
3. For
tub and shower installations
(see Figure 1). Pipe bottom outlet port “TUB” directly to the diverter tub spout. The mixer body is designed to operate without the use of a twin ell. Pipe top outlet
port “S” to the showerhead.
4. For
shower only installation
(see Figure 2). Pipe top outlet port “S” directly to the showerhead and plug bottom port.
5. Rough-in guide installation:
a. When piping installation is complete and before doing the finished wall, slide rough-in guide onto the mixer stem and press it into place (see Figure 4).
b. The rough-in guide will insure the proper size opening for mixer and checkstop shut-off and repair accessibility, as well as protect the chrome-plated sleeve from damage during drywall and tile
installation.
6. To install dial gaskets, peel backing off gaskets and attach gaskets to inside of dial plate. Attach indicator plate gasket to the back of the trim plate making sure horizontal holes on the gasket
matches horizontal holes on the trim plate. Indicator plate locator hole matches diagonal hole on the trim plate. Peel off backing of the trim plate gasket and attach to the inside top edge of the trim
plate. Gasket should be approximately 1/16˝ beyond the plate edge.
7. a. Install trim plate.
b. Snap on the indicator plate. Guide on the back of the plate goes into the locator hole.
c. Install sleeve O-ring on the bonnet. Slide sleeve on the bonnet.
CAUTION:
Indicator plate must be installed before sleeve.
d. Install handle and tighten the set screw.
CAUTION:
When soldering during installation process, do not
heat the valve any higher than the temperature required to flow solder. Excessive overheating of the valve may cause damage to the
cartridge mechanism.
By following this recommendation, you will be able to solder the valve without removing either the cartridge or the checkstop internals.
If either brazing or resistance (electric) solder is to be used, all valve internals must be removed.
8. Maximum temperature setting adjustment (see Figure 5) must be set on the job to in no case greater than 110°F (43°C). The high temperature limit stop is located on the bonnet.
Rotate handle to the maximum desired outlet temperature. With an open-end wrench, screw high temperature limit stop into bonnet until it touches stem’s shoulder.
Close valve and open it to full hot to verify settings.
