COMBUSTIBLE GAS DETECTOR
12
Return the sensitivity switch to HIGH before
searching for additional leaks.
When finished leak testing, turn OFF the instrument
and store it in a clean place. Protect the leak detector
from possible damage.
8. REPLACING NEW SENSOR
The sensor has a limited operative period. Under normal
operation, the sensor should be replaced once a year.
Exposing the sensor to high concentration of coolant
(>30000ppm) will shorten its life cycle rapidly. It is
important to make sure that sensor surface is free from
water droplets, vapor, oil, grease, dust and all other forms
of contaminants. For proper operation, the sensors must
be replaced annually or when contaminated.
WARNING! When replacing sensor, the
worn-out sensor may be HOT!!
(1) Remove cone cap cover from the tip of the probe.
(2) Pull out old sensor and insert the new sensor into the
plug (see below fig.2).
(3) Seal the cap cover over the plug.
