WIRING RUN THROUGH RIGID CONDUIT
1. Pull the wires from the probe canister into the junction box. Pull two wires from the console through the seal-off box
and into the junction box.
2. Using wire nuts, connect the two wires from the probe to the two wires coming from the console. Be sure to observe
color codes or tags when making these connections.
3. Do NOT terminate drain wire at this location, ground drain wire at console only.
4. Seal wire nuts with epoxy sealant using one bag for two-wire nut connections (Figure 12).
CAUTION:
Epoxy sealant is irritating to eyes, respiratory system, and skin. Can cause allergic skin reaction.
Contains: epoxy resin and cycloaliphatic epoxycarboxylate. Precautions: Wear suitable protective clothing, gloves,
eye, and face protection. Use only in well ventilated areas. Wash thoroughly before eating, drinking, or smoking.
5. Push the tie-wrapped, epoxy sealed bag into the junction box. Replace and tighten the junction box cover.
DIRECT BURIAL CABLE
When using direct burial cable for probe- or sensor-to-console wiring runs, the sealing materials and procedure are
completely different. If you are using Direct Burial Cable you must follow the sealing instructions in the Direct Burial
Cable Installation Manual.
