Technical Instructions
Installation ν
NOTE: Installation should be in accordance with accepted plumbing practices. Flush all piping thoroughly before installation.
1.Position mixer 115/16" ± 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.For standard inlets: Valve is factory-set for standard inlets ("TOP" stamped on stem should face shower outlet "S", see Figure 3.) If reversed inlets are required due to back-to-back installation (Cold water supply on the left and Hot water supply on the right), see Figure 3 and 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 high temp. limit stop and bonnet.
c.Rotate stem 180°, and reinstall bonnet and high temp. limit stop.
NOTE: Be certain the word "TOP" stamped on stem is facing toward tub outlet "T".
d.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 "T" directly to the diverter tub spout. The Biltmore mixer body is designed to operate without the use of a twin ell. Pipe top outlet port "S" to the showerhead.
Be certain that the bottom outlet port "TUB" is piped to the tub spout; if outlet connections are reversed, the mixer will not function properly.

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 completed and before doing the finished wall, slide rough-in guide onto the mixer stem and press fit into place. (See Figure 5.)
b.The rough-in guide will insure the proper size opening for mixer and checkstop shutoff 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.
7.After wall is completed, remove rough-in guide and attach dial assembly and handle to mixer body with the screws furnished. See Figure 4.
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 balancing 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 must be set at the job site. High temperature limit stop is located on the bonnet. Remove O-ring and discard. Slide the retainer and the high temperature limit stop out. Rotate stem to desired maximum temperature, but no greater than 115°F (46°C). Slide back the maximum temperature limit stop touching the tab on the stem. Slide the retainer back all the way to secure the high temperature limit stop. Install handle.
The maximum temperature setting must be re-adjusted if the hot water supply temperature is changed, and also seasonally to compensate for changes in the cold water supply temperature.
