OPERATION
Automatic operation is provided by the thermostatic
element. Element will control hot and cold supply based on
valve setting. If cold water is shut off, valve reduces mixed
flow in seconds (speed/residual flow rates vary by size).
CAUTION
Do not override calibration. Test temperature with
thermometers.
Service
To remove dirt, flush valve. To remove calcium and lime
deposits, soak valve in vinegar for 24 hours and flush or
contact factory for assistance. Do not attempt to field
repair this calibrated valve.
Temperature Selection
The MX Series Valves are made in ranges: 113°-149° F
(45°-65° C). The factory setting is 130° F (54° C). Change
temperature setting with an Allen wrench, which is
included; 3/16 for MX127LF or a 5/16 for MX128LF,
MX129LF and MX130LF. Punch through the center of the
temperature range label. By turning the screw clockwise,
the mix temperature increases (counterclockwise, it
decreases). Each complete turn with the Allen wrench
changes the temperature as follows: MX127LF (1 in.);
11° F (6° C), MX128LF (1-1/4 in.), MX129LF (1-1/2 in.)
and MX130LF (2 in.), 7° F (4° C). Do not operate valve at
temperatures outside of its calibrated range of 113°-
149° F (45°-65°). Use a thermometer to verify temperature.

Domestic Water Mixing
Use when water temperature produced by heater is hotter
than desired at point of use. Many codes require that water
supplied to the system be limited to 120° F (49° C) max.
