RECOMMENDED TOOLS
• (2) 12˝ (300 mm) adjustable wrenches
• (1) 12˝ (300 mm) pipe wrench
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 IEFB. It is not
recommended to mount the unit below the pipe (6 o’clock position).
2. Insert the IEFB in a pipe via a threaded Tee, Saddle, or welded integrally
reinforced branch connection outlet fitting.
a. If a Hot-Tap option is required for the IEFB, 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 mm) hole in the pipe is required for proper installation.
b. If a Hot-Tap option is required for the RTD thermowells, use a 1˝ valve kit
with proper mounting hardware available in Model A-IEFB-VLV-BR-1 or
A-IEFB-VLV-SS-1. A 1˝ (25 mm) hole in the pipe is required for proper
installation.
3. 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.
IEFB THERMAL ENERGY METER INSTALLATION
FLOWMETER INSTALLATION
1. To prepare the meter for installation, mount the provided alignment scale to the
side of the meter using the two captured thumbscrews, finger tighten only. Be
sure to orient the alignment scale as shown in Figure 5 below. Actual scale
setting determined in next step.
For Custom Configured Models (-CC Option) only. For field configurable
models, move to the next section.
2. Use the configuration tag attached to the Series IEFB to identify the value of
the alignment scale setting. Position the alignment scale such that the scale
setting is lined-up with the seam of the enclosure as shown in Figure 5. Securely
tighten the thumbscrews.
3. Skip to Preparing the Unit for Installation.
Note:
Minor scale marks are in 1/20ths and take in to account total installation depth.
For Field Configurable Models
2. For field configuration, a display is required (-LCD option or accessory
A-IEF-DSP) and needs to be powered via normal field wiring or with the AC wall
adapter accessory A-IEF-PA ( A-IEF-DSP and A-IEF-PA are also available in
the accessory setup kit A-IEF-KIT).
a. When using the AC wall adapter and the cable supplied, connect the red
(po) and black (common -) wires of the cable bundle marked “A” to
the open terminals of the AC wall adapter. This will provide temporary power
to the meter to complete the installation set up.
b. For field wiring, refer to the wiring chart tag attached to the Series IEFB
to identify the terminal block pins for positive (+) and common (-) connection.
If prewired, refer to wiring chart located on the tag.
c. Unscrew the four captured cover screws using the supplied 3 mm Allen
wrench to remove and set aside enclosure cover.
d. If using an A-IEF-DSP or the A-IEF-KIT, insert one connector of the ribbon
cable supplied in the setup kit into the connector labeled “Display” in the
middle of the unit. Be sure to orient the keying feature/tab. See Figure 6
below:
When installing a unit with an integral display select an installation
location that allows for clear viewing of the display and earth
ground.
