NOTE: Do not make sharp bends in the tubing. A sharp 

bend can break the tubing and cause a loss of fill. In 

models with an adjustable tubing length, pull the 

extra tubing out of the controller case.

d. Fit the controller case onto the immersion well so 

that the immersion well clamp slides over the flange 

of the immersion well.

e. Securely tighten the immersion well clamp screw.

6. For R8182H,J models:

a. Loosen the screw holding the hinged backplate to 

the controller case and swing the backplate away 

from the controller case.

b. Screw the backplate to a 4 by 4 inch junction box.

c. Insert the bulb into the immersion well until it 

bottoms.

d. If necessary, bend the capillary tube to hold the bulb 

against the bottom of the immersion well.

NOTE: Do not make sharp bends in the tubing. A sharp 

bend can break the tubing and cause a loss of fill. In 

models with an adjustable tubing length, pull the 

extra tubing out of the controller case.

e. Tighten the immersion well screw over the brass 

collar.

f. After wiring, swing control against the backplate and 

refasten with the screw.

7. Refill the boiler and check for water leakage.

If the existing immersion well does not fit the R8182D 

immersion well clamp, use a 1249094  immersion well adapter 

(order separately; see form 68-0040, Wells and Fittings for 

Temperature Controllers).

1. Disconnect the power supply.

2. Drain all water from the boiler.

3. Fasten the R8182D immersion well clamp to the flange 

on the immersion well adapter. Refer to Fig. 9.

4. Place the adapter on the capillary tube.

5. Put the adapter end into the hole in the controller case 

and tighten the clamp screw.

6. Insert the sensing bulb into the immersion well and 

bend the capillary tubing, if necessary, to hold the 

sensing bulb against the bottom of the 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. 

7. Apply the heat-conductive compound into the 

immersion well (if necessary).

a. Fold the plastic bag of heat-conductive compound 

lengthwise and twist it gently.

b. Cut off the end of the plastic bag and work the open 

end of the bag all the way into the immersion well.

c. Slowly pull the bag out of the immersion well while 

squeezing it firmly to evenly distribute the 

heat-conductive compound.

8. Wipe off any excess grease and tighten the set screw 

against the adapter.

If the existing immersion well is not usable, remove the 

existing immersion well and order a new one using form 

68-0040, Wells and Fittings for Temperature Controllers.

1. Disconnect the power supply.

2. Drain all water from the boiler.

3. Install the new immersion well by threading it into the 

threaded hole.

4. Loosen the immersion well clamp screw. See Fig. 9.

5. Insert the sensing bulb into the immersion well and 

bend the capillary tubing, if necessary, to hold the 

sensing bulb against the bottom of the 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. Apply heat-conductive compound into the immersion 

well (if necessary).

a. Fold the plastic bag of heat-conductive compound 

lengthwise and twist it gently.

b. Cut off the end of the plastic bag and work the open 

end of the bag all the way into the immersion well.

c. Slowly pull the bag out of the immersion well while 

squeezing it firmly to evenly distribute the 

heat-conductive compound.

7. Be sure the immersion well fits the hole in the controller 

case.

8. Position the immersion well clamp snugly over the 

immersion well flange. Securely tighten the clamp 

screw.

9. Refill the boiler and check for water leakage.
