SETUP
Selecting Installation Location
1. Although the unit may be installed in any orientation, the ideal mounting position
is on the side of the pipe (2 o'clock or 10 o'clock position) as this generally
minimizes possible air or sediment interference with the Series IEF.
Note: When installing a unit with an integral display select an installation
location that allows for clear viewing of the display and proper earth ground.
Insert the IEF in a pipe via a threaded Tee, Saddle, or welded integrally
reinforced branch connection outlet fitting.
If a Hot-Tap option is required, use a 1-1/4˝ valve kit with proper mounting
hardware available in Model A-IEF-VLV-BR or A-IEF-VLV-SS. A 1˝ (25.4 mm)
hole in the pipe is required for proper installation.

2. Select a location that will minimize flow distortion with adequate upstream and
downstream pipe diameters as displayed. Ideal installation will have a minimum
of 10 pipe diameters upstream relative to the instrument and a minimum distance
of 5 pipe diameters downstream.
INSTALLATION
1. To prepare the meter for installation, mount the provided alignment scale to the
side of the meter with the two provided thumbscrews. The thumbscrews are to be
inserted through the alignment scale slots and into the holes in the side of the lid
Series IEF
as shown in Figure 4, finger tighten only. Be sure to orient the alignment scale as
shown in figure below. Actual scale setting determined in next step.
