#3 Pressure – To the Sensor on the Meter
NOTE: Since the 3M tape provides a pressure sensitive seal, the installer must apply 15 lbs. of
pressure to the D4100 MOSAIC optical sensor immediately after attaching to the lens surface for a
minimum of 60 seconds.
1. Very Important: Press the adhesive down for 60+ seconds using 15 lbs of pressure. Allow 24-96
hours to cure.
2. Fasten the cable to the register with a zip tie.
3. Place Goop-Plumber’s Adhesive #15112 (purple tube) around the metal edge sensor and under the
tail of the sensor. Do not squirt the adhesive UNDER the 3M seal. The goal is to provide a
temporary water barrier between the meter face and the metal edge of the sensor, so that the 3M
adhesive can cure properly.
4. Position the flap at the base of the sensor so that it folds over and “hangs” above the register to try to
keep most of the stray light out while it processes through AutoCAL. The flap will be “pulled” over
the sensor snuggly lying flatter on the meter during the Read and Verify procedure that will be
discussed later.
