Installing EnviroSCAN, EnviroSMART & Diviner 2000 access tubes

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.
