Adjusting Mixing Valve Temperature
The supplied mixing valve is factory pre-set to 120ºF (49ºC). The valve temperature adjust range: 90°- 160°
F (32°C to 71°C). Maximum hot water temperature: 200°F (93°C). Temperture setting (within the valve
adjustment range) to be determined by local installation requirements.
8.
Let the water flow for at least two minutes to allow supply temperature to stabilize.
9. Place a thermometer in the outlet water stream.
10. Loosen handle screw with hex wrench.
11. Handle must be lifted 1/4” to adjust temperature. Rotate handle clockwise to decrease temperature and
counter-clockwise to increase the temperature.
12. Lower handle and tighten screw.
13. Check for outlet temperature.
A. Note: Pressure differential between hot & cold water supplies must be less then 25%.
Troubleshooting Plumbing
• Fluctuating or erratic hot water temperature at fixture:
○
Unbalanced Pressure. Install balancing or throttling valve at the hot and cold water supplies and adjust
accordingly for demand.
•
Hot water backing up into cold water line:
○
Hot water pressure is higher than cold water pressure. Examine check valves for dirt & debris, clean as
necessary.
•
Cannot adjust water temperature to desired temperature:
○
Install balancing or throttling valve at the hot and cold water supplies and adjust accordingly for
demand.
•
High pressure drop through the tempering valve:
○
Valve undersized. Install larger thermostatic tempering valve.
• Insufficient hot water during peak demand:
○ Check flow requirement during peak demand period. Use larger thermostatic tempering valve.
