Installation
Install Level Sensors
NOTE: Lower drum hardware must be installed in an
empty drum and then installed on the lower drum rack.
The drum can then be filled from the cascade feed hose
from a full upper drum.
NOTE: There are two possible locations for the low level
sensor, depending on desired function. Install both sen-
sors in the same location on each chemical side.
•
Low Level Indication: Located in the upper to
lower drum feed hose
•
Empty Indication: Located in the drum to pump
feed hose.
NOTICE
Do avoid machine damage, install one sensor on
each chemical side only.
1. Turn main power off.
2. Drain drums below the lowest level sensor well.
NOTE: For proper level sensor function, the tip of
the level sensor well must protrude at least 1/8 in.
into the tank.
3. Route the level sensor wire through the correspond-
ing well nut (CC). See F
bly view.

4. Measure the length of the level sensor well housing,
and then measure the depth of the hole in the fitting

where the well is inserted. Note these measure-
ments as they will be need later.
5. Being careful to not cross-threads, thread assem-
bled level sensor (CB) into well housing until it bot-
toms out against the bottom of the well. The bottom
of the level sensor will be slightly visible through the
bottom of the well.
NOTE: In the following step, do not allow PTFE
paste or tape to cover the tip of the level sensor
well. If paste comes in contact with the tip of the
level sensor well, thoroughly wipe it clean.
6. Apply PTFE paste and PTFE tape to the male
threads of the level sensor well housing.
7. Being careful to not cross-threads, thread the level
sensor well (CA) into the corresponding drum feed
port and lightly tighten with a crescent wrench.
NOTICE
Do not pressurize tank with level sensor removed
from sensor well. Doing so will rupture the level sen-
sor well.
8. The protrusion length must be at least 1/8 in.
(3.2 mm). If not, remove the level sensor well and
restart at step 4.
9. Rotate level sensor such that the cord is pointing
vertical and the sensing face is pointing down.
10. Plug the sensor connector (CD) into the level sen-
sors.
a. Route the sensor wires from the control panel
through the bushing that was installed with the
level sensor panel (steps 8 and 9).
11. Plug the sensor connector into the connector on the
FCM.
12. Calibrate the sensor. See Calibrate Barrel Style
Level Sensors, page 14.
