SS-TH500 - 1/2" MINIATURE THERMOSTATIC VALVE
Features:
Ability to pre-select water temperature – thus conserving water
Compensates for water pressure fluctuations preventing scalding
Safety button at 100°F prevents accidental scalding
High flow rates allow for multiple shower applications
Listed by NSF
Specifications:
o Operating pressure is 20 PSI to 85 PSI
o When pressure is higher than 85 PSI a pressure reducer (fitted before the valve) is required.
o Temperature range is 60°F to 115°F
o Recommended setting is 45 PSI and 150°F
Note:
DO NOT USE PLUMBER'S PUTTY ON ANY OF THE BRASS COMPONENTS
This will cause the finish to tarnish and void the warranty. A non-corrosive Alkoxy Silicone is
recommended.
DURING SWEATING OF LINES DO NOT OVERHEAT CASTING
Overheating may cause damage to internal mechanism and void the manufacturer's warranty as
well as increase the risk of scalding.
COPPER ADAPTORS MAY BE REQUIRED TO COMPLETE YOUR INSTALLATION
Shipping weight (lbs.): 4
Shipping dimension (in.): 6 x 5 x 4.5
Note:
Separate wall stops/shut off valves/volume controls (SS-TS150 or SS-TS200) may be needed in
conjunction with this valve. A thermostatic valve's only function is to mix temperature.

INSTALLTION FOR MINIATURE THERMOSTATIC VALVE Valve Installation 1. Flush the lines of all dirt and debris. Failure to completely flush the lines will cause valve failure and will void the manufacturer’s warranty. 2. Fit the valve on the wall without removing the plastic cover on the control spindle. Turning the control spindle will change the temperature setting which is pre-calibrated at the factory. -
