6. Insert sensing bulb into the immersion well and, if
necessary, bend capillary tubing to hold sensing
bulb against bottom of immersion well.
NOTE: Do not make sharp bends in capillary tubing. In
models with an adjustable tubing length, pull the
extra tubing out of the controller case.
7. If necessary, apply heat-conductive compound into
the immersion well.
a. Fold plastic bag of heat-conductive compound
lengthwise and twist it gently.
b. Cut off end of plastic bag and work open end of
bag all the way into immersion well.
c. Slowly pull bag out of immersion well while
squeezing it firmly to distribute compound.
8. Wipe off any excess heat-conductive compound
and tighten set screw against adapter.
If the existing immersion well is not usable, remove the
existing immersion well and order a new one using form
68-0040.
1. Disconnect power supply.
2. Drain all water from boiler.
3. Install the new immersion well by threading it into
the threaded hole.
4. Loosen the immersion well clamp screw. See Fig.
3.
5. Insert sensing bulb into the immersion well and, if
necessary, bend capillary tubing to hold sensing
bulb against bottom of immersion well.
NOTE: Do not make sharp turns while bending the
capillary tubing. In models with an adjustable
tubing length, pull the extra tubing out of the
controller case.
6. If necessary, apply heat-conductive compound into
immersion well.
a. Fold plastic bag of heat-conductive compound
lengthwise and twist it gently.
b. Cut off end of plastic bag and work open end of
bag all the way into immersion well.
c. Slowly pull bag out of immersion well while
squeezing firmly to distribute compound.
7. Be sure immersion well fits hole in controller case.
8. Position immersion well clamp snugly over
immersion well flange. Tighten clamp screw
securely.
9. Refill boiler and check for water leakage.
Mounting the R8182H
See Fig. 2 for R8182H installation dimensions and Fig. 5
for an internal view of R8182H.
1. Disconnect power supply.
2. Drain all water from boiler.
3. Most boilers are equipped with a tapping that
allows horizontal mounting of immersion well
where average temperature boiler water circulates
freely. If no tapping is provided, prepare one.
4. Install immersion well or compression fitting
(ordered separately) by threading into tapped hole.
5. Loosen screw holding hinged backplate to
controller case and swing backplate away from
case.
6. Screw backplate to 4 by 4 inch junction box.

7. Insert sensing bulb into immersion well and, if
necessary, bend capillary tubing to hold sensing
bulb against bottom of immersion well.
NOTE: Do not make sharp turns while bending the
capillary tubing. In models with an adjustable
tubing length, pull the extra tubing out of the
controller case.
