Maintenance . . .
Sensor may require a periodic cleaning of prism surface. Chlorinated
hydrocarbons must not be used for cleaning. A mild detergent may be
used to clean prism surface.

Installation . . .
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.
2. Thread sensor into tank wall and tighten by hand. Further tighten an
additional one to two threads past hand-tightness. (Avoid
overtightening, as this may damage threads.
3. Sensor may be installed in horizontal or vertical positions, only.
4. Do not install sensor close to infrared sources.
5. Prism surface must be at least 2" from any reflective surfaces.
6. Connect appropriate voltage supply to red lead. For 12 VDC units
(Part Numbers 153063 and 153064), connect to 12 VDC ±5% - For 5
VDC units (Part Numbers 153061 and 153062), connect to 5 VDC ±5%.
7. Output Configuration: See Fig. 1 and Fig. 2.
