ManualsBrandsAmerican Standard ManualsShop AllAmerican Standard Universal Thermostatic Mixing Rough-In Valve with Integrated Service Stops and Diverter - 2 Individual and 1 Shared Function

GENERAL DESCRIPTION:

Cast brass valve body. The single unit contains

two handles, the bottom handle sets the desired

temperature and the metal top handle controls

on/off, volume and diverter functions. The

temperature is maintained by a wax element

moving a shuttle valve between hot and cold.

The volume is controlled by twin ceramic disc

valve cartridges. Ceratherm includes Hot Limit

Safety Stop. Maximum temperature limit is 112°F.

1/2" NPT inlets and outlets.

PRODUCT FEATURES:

Brass Casting: Highest quality faucet material for durability & long life.

Built-in Diverter: Allows user to choose between 2 or 3 separate

shower outlets.

Wax Thermostatic Unit: Permits shuttle valve to move between the hot

and cold seat to maintain the pre-selected constant water temperature.

Back to Back Capable: Hot and cold can be reversed.

Spring-Loaded Check Valves: When the hot and cold water enters

the tting, both supplies pass through the spring-loaded check valves

to prevent cross ow of hot and cold water.

Integrated Stop Valves: Ensure easy cleaning and servicing.

Adjustable Hot Limit Safety Stop: Limits the amount of hot water

allowed to mix with cold. Reduces the risk of accidental scalding.

Maximum water temperature limit may be reduced to 104 or 109

degrees Fahrenheit.
