5. Installation - Adjust Packing Nut (Model Numbers Ending in TRMTC)
1) Turn hot and cold supplies on. Valve will not operate unless both hot and cold water supply pressures are on.
2) Place handle over flow control spindle.
3) Tighten packing nut for positive frictional resistance as handle is rotated from shut-o position across adjustment range.
6. Installation - Setting Limit Stop Screw (Model Numbers Ending in TRMTC)
1) Turn hot and cold supplies on. Valve will not operate unless both hot and cold water supply pressures are on.
2) Place handle on flow control spindle and open valve to maximum desired temperature.
3) Turn limit stop screw clockwise until it seats.
WARNING: Failure to adjust limit stop screw properly may result in serious scalding.
The temperature limit stop screw limits valve handle from being turned to maximum position resulting in excessive hot
water discharge temperatures.
