Figure 4 and Figure 5 .
OTEE: N It is not necessary to remove the aluminum housing from the transmitter to remove it from the line .
3 . Thoroughly wipe off the entire transmitter surface using mild detergent or isopropyl alcohol .
DO NOT USE AROMATIC HYDROCARBONS, HALOGENATED HYDROCARBONS, KETONES OR ESTER BASED FLUIDS ON
POLYCARBONATE LENS. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN DAMAGE TO THE TRANSMITTER.
4 . Remove the inlet port cap, wave spring, retaining ring, and cone assembly from the transmitter body (
Figure 9 ) .
5 . Gently push the body towards the outlet port .
6 . The piston, inner magnet and transmitter spring are secured within the transmitter body with a retaining ring . Remove the
retaining ring with a small screwdriver, then the internal components can be removed from the body ( Figure 9 ) .
OTEE: N If internal parts do not slide freely from cartridge, use a wooden dowel inserted into the outlet port of the meter to
push parts out .

port O-ring for damage and replace if required .
FIELD REPLACEMENT OF THE SPRING, METERING CONE AND/OR PISTON/MAGNET ASSEMBLY MAY RESULT IN CHANGES
TO THE CALIBRATION OF THE FLOW METER.
8 . Reassemble the transmitter by inserting the transmitter spring into the body, followed by the piston/inner magnet
assembly . A slight compression of the piston against the spring is required during installation of the retaining ring .
9 . Gently push body assembly into the outlet end of the transmitter enclosure . The flat surface of the body output port
should be flush with the transmitter enclosure opening .
10 . With the transmitter positioned vertically on a flat surface, inlet port facing up, install the transmitter cone assembly and
wave spring into the body and secure with the inlet port end cap .
11 . Reinstall transmitter to the line . Reconnect electrical power .
Inspection
1 . Frequent inspection should be made . The environment and frequency of use should determine a schedule for
maintenance checks . It is recommended that it should be at least once a year .
2 . Perform visual, electrical, and mechanical checks on all components on a regular basis .
3 . Visually check for undue heating evidence such as discoloration of wires or other components, damaged or worn parts, or
leakage evidence such as water or corrosion in the interior .
4 . Make sure all electrical connections are clean and tight and that the device is wired properly .
