Installation
FP90 series transmitters are available in two styles: panel mount and eld mount. The panel mount is supplied with the necessary
hardware to install the transmitter. This manual includes complete panel mounting instructions.
Field mounting requires one of two separate mounting kits. The FP90IM integral kit joins the sensor and instrument together into a
single package. The FP90UM Universal kit enables the transmitter to be installed virtually anywhere.
Detailed instructions for integral mounting or other eld installation options are included with the FP90IM Integral kit or the
FP90UM Universal kit.
Panel Installation
1. The panel mount transmitter is designed for installation using a 1/4 DIN Punch. For manual panel cutout, an adhesive
template is provided as an installation guide. Recommended clearance on all sides between instruments is 1 inch.
2. Place gasket on instrument, and install in panel.
3. Slide mounting bracket over back of instrument until quick-clips snap into latches on side of instrument.
4. To remove, secure instrument temporarily with tape from front or grip from rear of instrument. DO NOT RELEASE.
Press quick-clips outward and remove.
