16 Optional Sensors
Optional sensors are available for use in CO
2
(PN 724-701-G2) or flammable
refrigerant (PN 724-701-G3) applications. To use the CO
2
or flammable refrigerant
sensor, remove the standard sensor and install the new sensor following the
instructions in Removing and Installing the Sensor [
}
17]. D-TEK 3 automatically
recognizes the sensor type and the
MODE
indicator illuminates the appropriate color
to indicate the sensor type the entire time the sensor is installed. Green indicates CO
2
,
red indicates flammable refrigerant, and orange indicates the standard refrigerant
sensor is installed.
If D-TEK 3 does not automatically recognize your flammable refrigerant sensor,
contact JAVAC to arrange a software update.
The flammable refrigerant sensor does not detect hydrogen, including hydrogen
forming gas.
While searching for CO
2
leaks, it is recommended to wear a respirator or mask to
avoid exhaling CO
2
toward the probe.
WARNING
Exposure to high concentrations of CO
2
or refrigerants is dangerous and
can be life-threatening.
The instrument is not for use in toxic or hazardous environments. It is not a personal
protection or life-saving device. Always exercise extreme caution in potentially toxic or
hazardous environments.
WARNING
This product is not intrinsically safe and should not be used in the
presence of explosive fumes, explosive dust, or other explosive
chemicals. Use in an environment with flammable refrigerant
concentration approaching the LEL (lower explosive limit) could cause
an explosion or fire resulting in serious injury, death, or damage to
property.
