INSTALLATION & SERVICE
INSTRUCTIONS MODEL 170D-LF
WARNING!!
WATER TEMPERATURES IN EXCESS OF 110°F (43°C)
MAY CAUSE SCALDING, SEVERE INJURY, OR DEATH!!
IMPORTANT!
This thermostatic water mixing valves is NOT pre-set and
can be adjusted to deliver water at temperatures exceeding
110°F (43°C). After installation, the installer must check the
outlet water temperature and adjust the temperature setting
to ensure delivery of a safe water temperature not exceeding
110°F (43°C).
Periodic inspection and maintenance is required
Regular inspection of the valve and the outlet temperature
are required. Cleaning at a minimum of annually will help
assure proper function of the mixing valve. Frequency of
cleaning and inspection of the outlet temperature depends
upon local water quality conditions.
NOTE: DO NOT USE THREAD
SEALANT ON COMPRESSION
CONNECTIONS
PERFORMANCE:
 Maximum Pressure: 125 PSI (8.6 BAR)
 Maximum Hot water temperature: 180F (82°C)
 Hot water inlet temperature range: 120-180F (49-82°C)
 Cold water inlet temperature range: 33-80F (1-27°C)
 Outlet temperature range: 95-120F (35-49°C)
 Minimum flow certified to ASSE 1070: 0.25 GPM
 Maximum flow: 4 GPM
1. Valve should be installed where it can be easily cleaned, adjusted or repaired.
Leonard recommends that shutoffs are installed on the inlets to the mixing valve.
2. Inlets are furnished with 3/8” compression connections. If using copper tubing,
do NOT extend tubing more than 3/16” beyond the compression ferrule.
DO NOT use thread sealant.
3. Tighten compression nuts by hand, then tighten only 1/4 turn, overtightening will
cause leaks and possibly crush checks.
4. Flush the hot and cold water lines before installing mixing valve.
5. “H” and “C” are clearly marked on the inlets, install hot water line to inlet
marked “H” and cold water line to the inlet marked “C”. Valve can be installed in
any position.
6. Valve is NOT pre-set and must be set after installation. Run water for at least 1-2
minutes to allow water to stabilize.
7. Loosen locknut on stem, turn stem (screwdriver adjustment) counter-clockwise
(stem coming out of valve) for hotter and clockwise (stem going into valve) for
colder outlet temperature. Do not force the valve to below 90 F.
8. Tighten down the locknut to prevent unauthorized adjustment.
9. Verify the outlet temperature is set to the correct temperature.
TROUBLESHOOTING
PROBLEM CAUSE SOLUTION
Cannot reach desired outlet temperature Valve is full of debris or
Inlets supplies are reversed
Flush valve with water
Pipe hot to hot inlet, cold to cold inlet
Flow rate reduced or fluctuating Inlet screen filled with debris Check inlet screens for debris
No flow from outlet Hot or Cold water supply failure Restore Hot and Cold water inlet supplies
No flow from outlet Inlet supply tube extending more than 3/16” beyond
ferrule
Shorten tube and replace inlet checks
Hot water flows into Cold water supply or vice versa Check valve has debris, inlets were not properly flushed Replace inlet check valves and screens, KIT 4/108
Outlet temperature not warm enough
Hot water supply not 10 F above required outlet
temperature (5 F with equal pressures)
Increase Hot water inlet temperature
