Mount Base to Tank
Connect Electrodes to Case
If the required length of the electrode is greater than 39" (1 meter)
D
Install base (D) on tank and screw hand tight.
NOTE: The base threads are international standard
ISO7-RP2. While the international standard is not
identical to the standard National Pipe Thread
(NPT) or standard straight 2 inch pipe thread, it is
similar. As such a connection with 3 or 4 threads of
the base can be made in a 2 inch NPT pipe.

If using more than one electrode, allow space for maximum distance
between them.
a. Unscrew the case set screw (F). Back it out far enough to allow
for electrode insertion.
b. Thread the lock nut (G) onto the electrode (H) and place the
spring washer (J) on top of the nut.
c. Screw this assembly into the case until it stops. Tighten the lock
nut (G) until the spring washer (J) becomes flat. Tighten the set screw
(F) to 11 in. lbs. (12 cm kg.). Repeat step for each electrode.

a. Use an electrode separator (K) (not included) at each joint
when joining two electrodes together. This prevents the
electrodes from touching each other and false signaling.
b. Back out the two set screws (F) far enough so that the elec-
trode (H) clears them. Install a lock nut (G) and spring washer
(J) on each electrode. Screw the two electrodes into the con-
necting nut (L) so that they meet in the middle. Tighten the
lock nuts (G). Tighten the two set screws (F).
Assemble Case into Base
E C x 2
D
a. Mount the case and electrode assembly (C) into the
base (D). Note that there are holes in the base to
allow the nozzle to be positioned in 90 degree
increments.
b. Align the holes and tighten the two screws (E) holding
the base and case together.
