D D escription
This valve is precision engineered to provide satisfactory performance provided it is installed and operated in
accordance with our recommendations contained in these instructions. In order to fully enjoy the comfort,
safety and the reliability of this valve, be certain to familiarize yourself with these instructions.

Operation

The pressure balancing cartridge contained in this valve compensates for pressure fluctuations in the water
supply system through a diaphragm-connected pressure balancing mechanism. The outlet temperature will
change by no more than a mere ±2°F (1°C) with a 50% drop in either the hot or cold water pressure.
Even if the coldwater pressure fails completely, the anti-scald design will reduce the flow rate to a safe level
ensuring reliable protection against scalding. The built-in check valves prevent cross flow between the hot and
cold supplies.
