1. Use Teflon (TFE) thread tape or Permatex #80725 plastic pipe
sealant to seal thread. Caution: Pipe sealant must not come
in contact with prism surface. in contact with prism surface.

2. Thread sensor into tank wall and tighten by hand. Further tighten an
additional one-to-two threads past hand-tightness.

The test depicted below was performed to determine the sensor immunity level to ambient light. The recorded
ambient is the maximum level at which the sensor performs/detects normally.
