Install a strainer in the entering side of each piping
circuit to avoid possible tube plugging in the chiller
with debris.
Required Flow-Sensing Devices
The ifm efector® flow detection controller and sensor
(refer to
“Water Flow Detection Controller and Sensor
) is used to verify evaporator and
condenser water flows.
If a customer-supplied flow sensing device is used to
ensure adequate chiller flow protection, refer to the
wiring diagrams that shipped with the unit for specific
electrical connections.
Be sure to follow the manufacturer’s recommendations
for device selection and installation.

marker to draw a line on the probe at 3.5 in.
(8.9 cm) from the end of the probe. Do NOT
insert more than 3.5 in. (8.9 cm) of the
probe length into the pipe. Refer to the
following figure.

Temperature monitoring
Power-on delay time
Selection liquid / gas
Temperature monitoring can
also be incorporated using
terminals 10, 11, and 12.
To wire the flow monitoring
and wire-break monitoring
relay outputs in series, use
the wiring diagram at right.
Installation
1. Install adapter (A) into pipe.
2. Mount flow probe (B) into adapter (A).
3. Install DIN rail (F) into control cabinet.
4. Install control monitor (C) onto DIN rail (F).
5. Connect cable (E) to flow probe (B), (hand tighten only).
6. Wire cable in combicon connectors (D) according to
wiring diagram.
7. Wire relay outputs for flow, wire-break, and/or
temperature monitoring, according to wiring diagram.
If factory-provided,
located in control panel.
Do NOT insert more than
3.5 in. (8.9 cm) of the
probe length into the pipe.

Use a marker to draw a line
on the probe at 3.5 in. (8.9 cm)
from the probe end.
1. Mount the 1/2-in. NPT adapter in a horizontal or
vertical section of pipe. The maximum distance
from the control panel must not exceed 29.5 ft (9 m)
(see item labeled “1” in the preceding figure). Allow
at least five pipe diameters straight run of pipe
upstream of the sensor location, and three pipe
diameters straight run of pipe downstream of the
sensor location.

e:: In the case of a horizontal pipe, mounting the
sensor in the side of the pipe is preferred. In
the case of a vertical pipe, mounting the
sensor in a place where the water flows
upwards is preferred.

2. Insert the flow sensor probe (see item labeled “2”
in the preceding figure) through the 1/2-in. NPT
adapter so that 3 to 3.5 in. (7.6 to 8.9 cm) of the
probe’s length extends into the pipe. Tighten the 1/
2-in. NPT adapter as needed to prevent leakage and
keep the probe from backing out under pressure.

sensor probe must be at least 1 in. (2.54 cm)
away from any pipe wall. Do NOT insert more
than 3.5 in. (8.9 cm) of the probe length into
the pipe.
3. Install the Micro DC Cable by inserting it through
the wire openings on the back side of the control
panel (see item labeled “3” in the preceding figure).
Install the supplied Micro DC Cable (29.5 ft [9 m] in
length) to the Flow Probe and hand-tighten the
connector nut.
4. Plug the other end of the Micro DC Cable into the
Flow Control Monitor with the Combicon connector
(see item labeled “4” in the preceding figure). Refer
to the following figure for cable wiring.
