8. REPLACING NEW SENSOR
The sensor has a limited operative period. Under
normal operation, the sensor should work more than
one year. Expose the sensor under high density of
coolant (>30000ppm) will shorten its life cycle rapidly. It
is important to ensure that sensor surface is free from
water droplets, vapor, oil, grease, dust and any or all
other forms of contaminant. Furthermore, to ensure
good working condition of the unit, sensors must be
replacement periodically when its operative life is over.
WARNING!
When replacing new sensor,
the worn-out sensor may be HOT!!
(1) Remove cone cap cover from the tip of snake tube.
(2) Pull out old sensor and insert the new sensor into
