Inspecting and Cleaning the Valve
Shut off hot and cold water supply to mixing valve. Set
mixing valve handle on maximum hot position. Remove
body screws. Turn mixing valve handle toward “COLD”
position until it forces cover off valve body. The thermostat
can now be examined.
Checking the Thermostat
If there is a question as to the thermostat being good,
hold thermostat under cold water faucet and insert an
eraser capped pencil into the center of thermostat.
Make a reference mark where pencil protrudes from the
thermostat. Now place the entire thermostat into hot water,
approximately 125°F, for about one minute. Remove
thermostat from water, examine the reference mark on the
pencil again. At this temperature, it should extend out from
former position about 1/8’’. If it does not, a new thermostat
should be installed.
Checking the Piston and Liner
With a 1 3/8” socket (1/2” N.P.T.) or 1-5/8” socket (3/4”
N.P.T.) remove piston and liner assembly. Check to see if
the piston moves freely in the liner. If the piston is sticking,
place the assembly in a mild acidic solution. Work the piston
in the liner until free. Rinse the assembly in water. Be sure
to wear protective gloves when cleaning the assembly. If the
assembly is corroded or pitted, it should be replaced. Check
O-ring #22 and replace if necessary.
Piston and liner assembly consists of parts included in
assembly #12. (Only available as an assembly.)
Temperature Adjustment
Valves are normally set at the factory for 110°F maximum
outlet temperature. If it is desired to change this setting,
proceed as follows:
1. Allow water to flow through the controller.
2. Remove handle screw.
3. Turn adjustment handle to maximum hot position and
hold in that position.
4. With narrow blade screw driver, turn adjusting screw
#7 clockwise to reduce maximum outlet temperature
and counter clockwise to increase maximum outlet
temperature. Screw should not be turned more than 1/2
turn at a time without testing outlet water temperature.
5. When temperature is correct, replace handle screw.
If outlet temperature is to be 15°F or more higher than that
on the label, contact factory or Lawler representative for a
special thermostat.
