SENSOR
A
eL-320
sensor should last many hundreds of hours of
continuous operation. A failed or failing sensor will be indicated
by a continuous “siren” sound. In addition, it is recommended
that the sensor be replaced yearly for optimum performance.
SENSOR REPLACEMENT
In either case, occasional replacement of the sensor is
necessary:
1. Turn the power off.
2. Remove the sensor cap by pulling it from the end of the
probe.
3. Pull the old sensor from the socket.
4. Install the new sensor. Note that the sensor package has a
tab that needs to be aligned with a slot on the sensor socket.
5. Install the sensor cap by pushing it fully over the sensor.

MAINTENANCE
The EL-320 should provide years of service with little
maintenance aside from changing batteries and sensors. The
case may be cleaned with a shop towel moistened with water
and a mild detergent. Do not use solvent of any kind.
