Dwyer Instruments IEF Series Installation Instructions page 3

For Custom Configured Models (-CC Option)
2. Locate the configuration tag attached to the Series IEF 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 4. Minor
scale marks are in 1/20ths Securely tighten the thumbscrews.
3. Refer to Preparing the Unit for Installation section.
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).
3. When using the AC wall adapter and the cable is supplied, connect the red
(positive +) 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.
4. For field wiring refer to the wiring chart tag attached to the Series IEF to identify
the terminal block pins for positive (+) and common (-) connection.
5. Unscrew the four captured cover screws using the supplied 3 mm Allen wrench
to remove and set aside enclosure cover.
6. 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 5 below:
7. Plug the other end of the cable into the bottom of the supplied portable display
being sure to orient the keying feature/tab as shown:
8. Apply power to the unit and the display will turn-on automatically. Follow the on
screen directions for entering the necessary parameters to setup the unit and
obtain the alignment scale setting value.
NOTICE Precise pipe measurements are required for high performance
installation. The A-IEF-KIT includes setup display A-IEF-
DSP, thickness gage UTG and measuring tape A-IEF-MSTP used to obtain these
measurements. When the precise pipe measurement information is known select

1. Apply appropriate sealant to the process collet (5) threads such as application
suitable sealant tape or paste.
2. Install the process collet (5) in valve (6) then tighten by hand.
3. Tighten the process collet (5) with a wrench using the hex geometry until snug.
Use two wrenches, one to hold the valve and another wrench to

turn the process collet.
4. Slowly open the valve handle (7) checking for leaks.
5. If leaks occur around threaded connections, close the valve and tighten those
connections.
