4. Measure the time when the pump starts and stops
operating, and if it stops within 5 seconds, the
pressure switch inside the pump is normal.
5. Measure the pressure 10
− 20 seconds after the
pump has stopped.
Standard value: 24.5
− 39 kPa (-30 − 0°C),
24.5
− 34 kPa (0 − 100°C)
6. If the pressure is within the standard value, the
release valve inside the pump is normal.
7. Check the pump does not begin operating for 5
minutes after it has stopped.
8. If the inspection for steps 4-7 is normal, the pump
is fully operational.
