SEALING FIELD CONNECTIONS
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. Figure 11 diagrams a typical probe field wiring
connection in the junction box.
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).
5. Push the tie-wrapped, epoxy sealed bag into the junction box. Replace and tighten the junction box cover.

Instructions:
NOTE: When temperature is below 50˚F (10˚C), keep
resin in a warm place prior to mixing (e.g., in an
inside pocket next to body).
1. Open epoxy sealant package, and remove resin pak.
2. Holding resin pak as shown in A, bend pak along long
length.
3. As shown in B, firmly squeeze the RED SIDE of the
resin, forcing it through the center seal and into
BLACK SIDE.
4. Mix thoroughly to a uniform color by squeezing
contents back and forth 25-30 times.
5. Squeeze mixed, warm resin into one end of bag and
cutoff other end.
6. Slowly insert wiring connections into sealing pack
until they fit snugly against the opposite end as
shown in C.
7. Twist open end of bag and use tie wrap to close it off
and position the tie wrapped end up until the resin
jells.
CAUTION:
Epoxy sealant is irritating to eyes, respiratory system,
and skin. Can cause allergic skin reaction. Contains: epoxy resin
and Cycloaliphatic epoxycarboxylate.
Precautions:
