The temperature of the water delivered by the HOLBY TEMPERING VALVE can be changed by turning the adjusting screw clockwise for lower temperatures and counter-clockwise for higher temperatures.
What temperature should a mixing valve be set at?
The recommended and also factory set temperature setting is 120 F. If the temperature is around 120 F, it will take 5 min for 2nd and 3rd-degree burns on the adult skin.
Can mixing valves be adjusted?
To adjust the temperature of the valve, you have to remove the cap . The temperature should be reduced and the temperature increased until the desired set point is reached.
How do I adjust my mixing valve wattage?
To adjust the setting of the valve, loosen locking cap screw with hex wrench , see Figure 2. Cap must be lifted 1/4” to adjust temper- ature. To increase the tem- perature, turn counterclockwise. To decrease temperature turn clockwise.
How do you adjust the temperature on a mixing valve?
To adjust the temperature supply remove the plastic cap on top of the valve and adjust with a close fitting spanner. To increase the temperature turn anti-clockwise To decrease the temperature turn clockwise To set the valve to a maximum recommended mixed water temperature, see table below.
Can you adjust a shower mixing valve?
The mixture of hot water and cold water available in a shower or tub can be adjusted at the shower valve stem , the part found under the faucet. ... Take off the metal cover beneath the handle, exposing the valve stem. You'll see a plastic part around the valve stem.
What happens when a mixing valve fails?
A defective mixing valve will allow a cross-over of hot and cold water , even though there are no visible signs of trouble or leak. A plumbing cross-over can cause a complaint such as ‘water not hot enough'.
Is a mixing valve code?
Master mixing valves are not mandated in the model plumbing codes , but it is good design practice for a constant hot water supply temperature. Domestic hot water systems are unique in that a change of equipment in one part of the system can and most likely will affect the performance of another part of the system.
How do you test a mixing valve?
- Measure the mixed water temperature.
- Isolate the cold water supply to the TMV.
- Wait for at least five seconds.
- Check if the water temperature is below 46oC.
- If there's no significant temperature change (2oC or less) it means the valve is performing optimally.
Which way do you turn a mixing valve?
To adjust the mixed outlet temperature of the valve, remove the cap to gain access to the adjusting spindle. The spindle should be rotated-clockwise to reduce the temperature, counter-clockwise to increase the temperature until the desired set point is reached.
What causes a mixing valve to fail?
Inconsistent hot water – older model hot water mixing valves can begin to fail to correctly control water temperature as they age with use , and may lack newer temperature balancing features that can effectively maintain any fluctuations in water temperatures that occur within the plumbing system.
How does a Watts mixing valve work?
Once tempered water is in use, a thermostat in the mixing chamber of the valve senses the outlet temperature and automatically positions a seat assembly, which controls the flow of hot and cold water supplied to the mixing chamber.
How do you adjust a commercial mixing valve?
ADJUSTMENT Open fixture downstream as the valve must be set under flowing conditions. Turn the adjusting knob/bolt accordingly to increase or decrease temperature at the fixture or measurement port. Turn the knob/bolt clockwise for lower temperatures or counterclockwise for higher temperatures.
