• To check valve opening temperature, suspend the thermostat [A] in a container of water and raise the temperature of the water. OThe thermostat must be completely submerged and must not touch the container sides or bottom. Suspend an accurate thermometer [B] in the water so that the heat sensitive portions [C] are located in almost the same depth. It must not touch the container, either. *if the measurement is out of the specified range, replace the thermostat with a new one.
Thermostat Valve Opening Temperature 58 ~ 62°C (136 ~ 144°F)
