4. Installation - Remove Test Cap (Model Numbers Ending in TRMTC)

Flow control spindle (TA-10) and cap assembly (T-12A) will
come factory assembled for all model numbers ending in
TRMTC. When ready to remove Test Cap and install trim,
follow the instructions below:
1) Check for leaks around the valve assembly and all pipe
fittings.
2) Remove test cap from valve (FIGURE 4.1).
3) If system is dirty, flush valve.
4) Thread flow control spindle and cap assembly into valve
body. Turn clockwise to secure to valve (FIGURE 4.2).

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-off position across adjustment range.
6. Installation - Setting Limit Stop Screw (Model Numbers Ending in TRMTC)
The temperature limit stop screw limits valve handle from being turned to maximum position resulting in excessive hot
water discharge temperatures.
WARNING: Failure to adjust limit stop screw properly may result in serious scalding.
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.
