Installation Install the TCO1 between the hot water outlet of the mixing valve and the equal tee that houses the thermometer. Important note: The TCO1 must be installed with the end marked 'inlet' connected to the mixing valve and the end marked 'outlet' connected to the equal tee. (These markings are stamped onto the hexagon end connections). If the valve is installed in reverse it will never be able to operate.
K v value 1" = 8.5. For conversion:
C v (UK) = K v x 0.963 C v (US) = K v x 1.156
