UMV500 Series
UNIVERSAL UNDERSINK
THERMOSTATIC MIXING VALVE
GENERAL
The UMV500-LF/U UMV Series Universal UnderSink
Thermostatic Mixing Valve is intended for use in
under counter and under sink applications. The
UMV500 Universal Model is designed to be used as a
three port design (touchless sink) or a four port
design (two handle sink) with the addition of the 4
port adaptor (supplied with UMV500-LF/U).
The UMV500-LF/U is used to prevent accidental
scalding. The outlet water temperature must be
properly adjusted by the installer using a
thermometer to measure the outlet temperature at
the faucet. A maximum outlet temperature of 110° F
(43° C) is recommended.
