Replacing the Sensor:
The sensor is a plug-in unit that can be
thrown away when expended. It needs
replaced when the H-10PM no longer
responds to the Calibration Reference Bottle,
even with the Heater Adjustment turned fully
clockwise (make sure the reference bottle
contains some refrigerant).
1. Turn the leak detector OFF.
2. Unplug the power cord if the unit is
plugged in and open the sensor cover.
3. Allow the sensor to cool before
touching it.
4. Unplug and discard the sensor.
5. Insert a new sensor and close the sensor
cover.
6. Turn the Heater Adjustment to its full
counterclockwise position.
7. Apply power to the unit and adjust
the sensor’s heat setting (see “Heater
Adjustment” section).

Caution: Personal Injury Hazard
