System Requirements
- This thermostatic valve is designed for use with pressurized hot and cold water supplies only and should not be used
with low-pressure storage heating systems.
- This valve was factory set to 100°F maximum at a pressure of 45 PSI. The actual temperature must be checked due to
water temperature and pressure deviations.
Pressure: Recommended range 30 PSI - 70 PSI
1/2” Valve: 1/2” NPT inlets and outlets
3/4” Valve: 3/4” NPT inlets and outlets
Temperature:
Hot water inlet - 165°F Max. - 130°F Min.
Marked dial range - 70°F - 120°F
Safety stop - Adjustable

[STEP 1] ROUGH VALVE INSTALLATION (J-TH34/J-TH12)
1. Position valve assembly so outer edge of nished wall is between min./max. thickness marked on rough in
shield. Figure 2
2. Using appropriate fasteners, mount valve assembly to studs/blocking. Figure 1
3. Remove cartridge and check stops. Page 6
4. Connect inlet and outlet port piping.
5. See “Rough in plumbing and valve ushing”. Page 9
6. Turn on water supply and ush valve with cartridge and check stops removed. Page 9
7. Turn off water supply and re-install cartridge and check stops. Page 10
8. Turn on water supply and test for leaks and all functions.
9. Continue on to Page 11 & 12

[STEP 3] PLUMB ROUGH USING APPROPRIATE FITTINGS
Diverter and Thermostatic valve are factory sealed, do not separate!
1. Plumb hot and cold inlets on thermostatic body. Part #’s: J-TH34. J-TH12, J-TH34-686, J-TH34-688,
J-THVC12. Figure 8
2. If using lower port on thermostatic body, a separate volume control is required. If not, port must be plugged.
Figure 8
3. Select diverter ports to be used. C, A, B and plumb with appropriate ttings. Part #’s: J-TH34-686,
J-TH34-688, J-20686 and J-20688. (Note: Port A is not used with the 2-way diverter and must be capped)
Figure 8
Note: Two way diverter can be used as a single outlet and volume control by capping B or C port. Three
way diverter can be used as two way diverter by capping any single port or a volume control by capping
any two ports.

SPINDLE
[STEP 5] REASSEMBLY (REASSEMBLE IN REVERSE OF STEPS ON PAGE 6)
1. DIVERTER:
a. Inspect and remove any debris in diverter body
b. Re-install diverter into body so nub from cartridge goes into detent in valve
c. Install locknut using 1” wrench, tighten nut and replace spline adapter
2. THERMOSTAT:
a. Inspect and remove any debris in thermostatic body, including check stop cavities
b. Apply lubricant suitable for potable water to the o-rings on the thermostatic cartridge, and insert into valve
body rotating back and forth slightly. Orient cartridge with the notch up in the 12 o’clock position for J-TH34
and and J-TH12 and 6 o’clock position for J-THVC12. Figure 10
3. Re-install thermostatic cartridge locknut using a 1-1/4” wrench and tighten nut
4. Re-install hot and cold check stops, rotating back and forth until seated
5. Re-install check stop locknuts using a 13/16 (6 point) socket, tighten nuts
Helpful hint: Place locknut over at tip screwdriver, press screwdriver and check stops down (spring loaded) then start
locknut by hand
**NOTE: CHECK STOPS ARE DIRECTIONAL. ENSURE ARROWS POINT TO CENTER OF VALVE FOR ON POSITION**
