INSPECTION

PROCEDURE

1. INSPECT WATER INLET WITH THERMOSTAT SUB-ASSEMBLY

CAUTION:

  • 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.

(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.
