Rotating the Enclosure
The Model F-5500 has been designed to allow the enclosure to rotate into four
positions for optimal viewing of the display. To rotate the enclosure, first loosen the
two set screws near the Flow Direction Indicator. Then unscrew and remove the Flow
Direction Indicator to allow the enclosure to swivel into the desired position. Then
screw the Flow Direction Indicator back into its place, ensuring that it points in the
direction of flow, and tighten the set screws.

Install the meter with the flow direction indicator pointing in the direction of flow in the
pipe.
Compression Fittings
While holding the fitting body steady, finger tighten the nut. Then, tighten the nut with
wrenches an additional one and one-quarter (1 ¼) turn. If beginning at 6 o'clock, the
wrench would make one full turn back to 6 o'clock and rest at the 9 o'clock position for
proper compression. See Figure 2.9 below.
CAUTION! Tightening the compression fitting will crimp the fitting to the stem of the
flow meter and lock the depth setting into place. Don’t tighten the compression fitting
until you’ve completed all steps in the installation section of this manual.
