2.1.1 Installing a Moisture Probe
1.
Screw the probe into the receptacle fitting, making sure not to cross
thread it (see Figure 10). Install moisture probes with different fittings
in the appropriate manner.
Note:
Standard moisture probes have a sintered stainless-steel shield that
protects the aluminum oxide sensor. Leave the shield in place for
maximum protection.
