2. Take a silicon gun with a new nozzle and apply three rings of silicon around the outside of
the access tube, approximately 1 cm (0.4 inch) below the top rim of the tube.
3. Unscrew the cap from the top cap assembly base.
4. For
EnviroSCAN and EnviroSMART applications, feed the cable through the FairRite bead
and then through the cable gland.
5. Take the top cap base and slowly push it onto the top of the access tube with a slight
forward and backward rotating motion until the bottom foot of the top cap touches the
undisturbed soil surface. This will distribute the silicone evenly.
Note: Ensure that no soil, grass or other material is present between the
top cap and access tube, as this can provide pathways for water
movement through the silicon and into the top cap.
6. For
EnviroSCAN and EnviroSMART installations, ensure that the cable gland is pointing in
the direction that the cable is to be laid.
7. Wipe off any excess silicon from inside the access tube.
