8. For EnviroSCAN and EnviroSMART probes, strip back the outer sheath of the cable until the
end of the outer sheath sits just inside the cable gland. Fill around the wires inside the end
of the cable sheath with silicone to prevent moisture from travelling along the cable into the
top cap. Insert the electronics and connect the cable to the probe interface. For further
details on wiring of probes refer to the EnviroSCAN and EnviroSMART hardware manuals.
Position a dry silica gel bag on top of the electronics.
9. Screw the top cap back onto the top cap housing. For EnviroSCAN and EnviroSMART
probes, tighten the FairRite Bead on the cable next to the top cap.
Troubleshooting the standard manual installation method
The following alternative access tube installation techniques may be used when the Standard manual
installation method proves unsuccessful.
Read the description of the problem and its solution. Select the solution that best fits your situation before
trying the method. Alternative tools are available to assist in difficult installations and can be purchased
separately as optional items (refer to section on Toolkit Items).
Moist and sticky heavy clay soils
Under moist and sticky, heavy clay conditions, the standard method of augering through the access tube and
hammering in the access tube may be too strenuous using the 47.0 mm regular auger. If this is the case,
use the following installation method.
To install access tubes in moist and sticky heavy clay soils
1. Ensure the tripod is set up correctly and centred over the installation site.
2. Select the 53 mm Clay auger and the required extension rods.
3. Fit the Auger Stabilisation Poly Guide over the extension rods and attach the T-Handle.
4. Put on gloves and safety goggles to protect your hands and eyes from damage.
