INSPECTION
PROCEDURE
1. INSPECT WATER INLET WITH THERMOSTAT SUB-ASSEMBLY
HINT:
The valve opening temperature is inscribed on the water inlet with thermostat sub-assembly.
(a) Immerse the thermostat in the water, then heat the water gradually.
CAUTION:
- Do not your hands into the water that has been heated for the inspection.
- Touching the heated water could result in burns.
(b) Check the valve opening temperature of the water inlet with thermostat sub-assembly.
Standard valve opening temperature:
85 to 89°C (185 to 192°F)
NOTICE:
When checking the water inlet with thermostat sub-assembly in water, keep the terminals dry. After the check, wipe the water inlet with thermostat sub-assembly dry.
If the valve opening temperature is not as specified, replace the water inlet with thermostat sub-assembly.

(c) Check the valve lift. Text in Illustration
Standard valve lift: 8.0 mm (0.315 in.) or more at 100°C (212°F) If the valve lift 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 a low temperature (below 40°C (104°F)).
If the valve is not fully closed, replace the water inlet with thermostat sub-assembly.
(e) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
