8. Apply approved adhesive around the sensor to seal it completely if the pit fills with
water prior to the 24 - 96 hour cure time, or if the meter face is curved and not flat.
Note: If the sensor is initially misplaced, do not attempt to remove the
sensor by twisting the sensor body. A fully cured sensor requires
breaking the seal at the adhesive tape joint with a flat tool such as a
screwdriver. Insert the screwdriver between the aluminum base and
meter lens and twist.
