REPLACE THE
ELECTRODE ASSEMBLY
Use the following procedure to replace the electrode assembly
into the flowtube.
1.
Lubricate the o-ring.
2.
Install the o-ring on the electrode.
3.
Insert the electrode into the electrode housing. Push straight in until
the electrode is seated. Avoid rotating the electrode or the electrode
housing as this could result in leakage.
4.
Secure the electrode into the housing with the retaining nut and lock
washer. Tighten the retaining nut to 15 in/oz of torque. Failure to
tighten the fasteners can cause loss of liquid tight seal and result in
damage to the unit.
5.
Secure the signal wire to the electrode with the electrode lead screw.
6.
Install the o-ring into the electrode cover.
7.
Secure the electrode cover to the flowtube with the screws.
