Maximum permissible temperature in accordance with ASSE 1070. The limit locking ring may be adjusted for applications not requiring
ASSE 1070 valves.

Maximum allowable variation in either supply pressure in order to control the outlet temperature to within +/- 3
o
F. Warning: Pressure
variations outside of this range may cause changes in the outlet temperature.
NOTE: At low flow operation, the outlet temperature may vary slightly more.
Differential pressure at the valve inlet should be within a 2 to 1 ratio under normal flow conditions.
Inline fittings, pipe work, layout and sizing must be taken into consideration. In installations where the valve is supplied with unbalanced
hot cold pressures greater than a 2 to 1 ratio, please call HTP Technical Support Department.
Installation of the Mixing Valve
1. Flush all pipe work thoroughly (with water only) before installing the mixing valve.
2. The mixing valve comes complete with union type connections for ease of installation and service.
3. The mixing valve must be removed from the pipe work prior to soldering the end connections. It is recommended to use a spacer
piece while soldering.
Do not solder unions while attached to the valve body. Solder connections prior to connecting unions to the valve body to avoid
damaging the valve and its function.
Setting the Mixing Valve Outlet Temperature
1. Turn both the hot and cold water supplies on. Open an outlet, preferably a sink or basin faucet rather than a shower. To calibrate, let
water run for 2 minutes and measure the outlet temperature with a thermometer. Adjust the green cap counter clockwise to increase
temperature and clockwise to decrease temperature, as shown in Fig. 4.

2. Once the desired outlet temperature has been achieved, refit the green top so that it snaps onto the body of the mixing valve.
