PROCEDURE

Hide 16031 1.INSPECT WATER INLET WITH THERMOSTAT SUB-ASSEMBLY

CAUTION:
A342307

·

Do not put your hands into the water that has been heated for the inspection.


·

Touching the heated water could result in burns.



HINT:

The valve opening temperature is inscribed on the water inlet with thermostat sub-assembly.


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 connector of the water inlet with thermostat sub-assembly.



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.

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.


d.

Check that the valve is fully closed when the water inlet with thermostat sub-assembly is at low temperatures (below 72°C (162°F)).
