GENERAL DESCRIPTION:
Cast brass valve body. The single unit contains
two handles, the bottom lever handle sets the
desired temperature and the top handle functions
as an on/off, volume control. 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. Escutcheon
plate is stamped brass. Available with 1/2" or 3/4"
NPT inlets and outlets. The valve has a high ow
rate, ideal for mutiple outlet installations.

PRODUCT FEATURES:
Brass Casting: Highest quality faucet material for durability & long life.
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.
SUGGESTED SPECIFICATION
