(a) Immerse the water inlet with thermostat sub-assembly in water and then gradually heat the water.
NOTICE:
Do not allow any water to come into contact with the water inlet with thermostat sub-assembly connector.
(b) Check that the valve of the water inlet with thermostat sub-assembly opens at the specified temperature.
Standard Valve Opening Temperature:
80 to 84°C (176 to 183°F)
If the result is not as specified, replace the water inlet with thermostat sub-assembly.
| (c) Check the valve lift. Standard Valve Lift: 8.0 mm (0.315 in.) or more at 95°C (203°F) If the result is not as specified, replace the water inlet with thermostat sub-assembly. |
