Replacing a Thermostat Cartridge
The thermostat replacement procedure is as follows:
1. Shut off the hot water supply and cold water supply to
the mixing valve.
2. Remove the four cover screws (#9) and remove the
front cover (#26) of the valve.
3. Remove thermostat (#11) from the valve body.
No special tools are necessary.
4. Insert a dowel rod, pencil (eraser-end), or narrow pen
into the open end of the thermostat. Push on the dowel
rod with your hand. If the thermostat feels spongy
or springy, the thermostat has lost its charge. If the
thermostat feels solid or hard, the thermostat is good
and operable.
5. Be sure that the stainless steel piston (#15) moves
freely up and down within the liner (#21). Lime or
calcium buildup should be cleaned with vinegar, green
scotch pad, or fine emery cloth.
Setting the Mixing Valve
Prior to adjusting the temperature on the emergency mixing
valve be aware that prior to shipping this valve was tested
and set at the factory. Please make sure that isolation
valves and check valves are installed and that incoming
hot and cold pressures are equal before any adjustment
is made. If these parameters are not present, DO NOT
proceed to “Setting the Mixing Valve” until these parameters
are met. IT IS ADVISED TO CALL THE FACTORY PRIOR
TO DOING ANY TEMPERATURE ADJUSTMENTS ON ANY
LAWLER EMERGENCY THERMOSTATIC MIXING VALVE.
This mixing valve has been set at the factory to deliver
85°F outlet flow. Should the valve require adjustment, or an
application require a different set temperature, proceed as
follows:
1. Contact the proper medical and safety authorities to
determine correct water temperature for the specific
application.
2. Use a spanner wrench to remove the tamper-resistant
cap screw.
3. Create a draw on the mixing valve by opening a
downstream eye wash fixture.
4. Insert a 5/32” allen key into the cap opening of the valve
(V1) and seat in the adjustment screw (not shown). Set
the outlet temperature by turning the adjustment screw
clockwise to reduce temperature, counterclockwise
to increase temperature. Use thermometer (T1) to
measure the outlet temperature.
5. Replace cap screw.
