Disclaimer Regarding Roman Tub with Hand Spray
To conform to local codes and ordinances, all Roman tub with hand spray products should be used in concert with an
ASSE 1016 approved tempering valve to reduce the hot water supply to a safe temperature not exceeding 110°F
(43°C).
Important: Water temperatures in excess 110°F (43°C) are dangerous and may cause scalding, severe injury of death!
Tempering valve should be installed and adjusted by a licensed contractor per the valve manufacturer installation
instruction, and in accordance with local codes and ordinances. In general, key characteristics to ensure a tempering
valve to work best with Roman tub with hand spray products shall be as follows:
• Tempering valve should be used prior to the Roman tub product to reduce the hot water supply to a safe tempera-
ture.
• To ensure sufficient water flow through the tub spout, tempering valve should be capable to handle a flow rate of 10
gpm or more.
• Tempering valve should include inlet filter washer and check valves in both the hot and cold water inlets to protect
against cross flow.
Pressure - Temperature - Flow Rate
Minimum supply pressure static: 30psi (207 kPa)
Inlet temperature: hot inlet, 120°F – 180°F (49°C – 82°C)
cold inlet, 39°F – 85°F (4°C – 29°C)
Temperature out: Field range: 80°F -120°F (27°C – 49°C), adjustable. Accurate within +/-3°F (1.7°C)
Maximum temperature: 200°F (93°C)
Maximum pressure: 150psi (10.3 bar)
Minimum flow: 0.5 gpm (1.9 lpm) @ 0.8psi (0.55 kPa)
Maximum flow: 20 gpm (76 lpm) @ 125psi (862 kPa)
*Note: Valve should be installed in a location where it is accessible for cleaning or service. Due to the effects of vari-
ous water conditions, periodic verification of outlet water temperature is required.
