1. Empty the tank.
2. Insert the PTFE proximity sensor well (2102) into
the tank and turn until flush with the flat face of the
tank.
3. Insert the proximity sensor (2101) into the proximity
sensor well (2102).
4. Hand tighten the well cap (2103) into the proximity
sensor well.
5. Plug the sensor connector (2104) into the connector
on the Fluid Control Module as shown in F
Each machine will have either one or two Fluid
Control Modules, each labeled as #1 or #2. Fluid
Control Module #1 is always used for the low level
sensors. Fluid Control Module #2 is always used
for the high level sensors. See F
6. Calibrate the sensor. See Level Sensor Calibra-
tion, page 20.

Accumulators
The accumulator level sensors (144) can be
installed on any side of the main cylinder (123).
However, the sensor must be the specified dis-
tance from the pump flange.
CAUTION
To prevent machine damage, if the material being
cycled through the accumulator is moisture sensitive,
a dryer must be installed in the air supply line before
the accumulator.
1. Place the main sensor body (144a) against the side
of the main cylinder (123) wall.

2. Line up the bolt holes of the clamp (144b) and the
main sensor body (144a). Lightly clamp the two
together around the nearest tie rod by finger tighten-
ing the socket head cap screw (144c) provided.
3. For accumulator low level sensors, once the
screw (144c) is finger-tight, slide the sensor (144)
so it is located 1/2 in. (13 mm) above the bottom
pump flange (111).
For accumulator high level sensors, once the
screw (144c) is finger-tight, slide the sensor (144)
so it is located 1-1/2 in. (38 mm) below the top pump
flange (111).
4. Plug the sensor connector into the connector on the
Fluid Control Module as shown in F
Each machine will have either one or two Fluid
Control Modules, each labeled as #1 or #2. Fluid
Control Module #1 is always used for the low level
sensors. Fluid Control Module #2 is always used
for the high level sensors. See F
