(
°F
:
)
The temperature settings below are examples. The temperature setting
necessary depends on the usage, the length of piping and the time of year.
*Initial factory setting is 110°F
If xtures incorporate mixing valves, set the temperature higher than usual.
*
For most residential applications, the recommended temperature setting is 120°F (50°C in °C mode) or less.
* Consult local codes for minimum operating temperatures.
