) are used to verify evaporator and
condenser water flow s.
If a custom er-supplied flow sensing device is used to
ensure adequate chiller protection, refer to the w iring
diagram s that shipped w ith the unit for specific electrical
connections.
Be sure to follow the m anufacturer ’s recom m endations for
device selection and installation.

1.
M ount the 1/2-in. NPT adapter in a horizontal or
vertical section of pipe. The m axim um distance from
the control panel m ust not exceed 8.99 m eters (29.5 ft)
(see item labeled “ 1” in
Figure 10, p. 23
). Allow at least
five pipe diam eters straight run of pipe upstream of the
sensor location, and three pipe diam eters straight run
of pipe dow nstream of the sensor location.
N ot e: In the case of a horizontal pipe, m ounting the
sensor in the side of the pipe is preferred. In the
case of a vertical pipe, m ounting the sensor in
a place w here the water flow s upwards is
preferred.
2. Insert the flow probe through the 1/2-in. NPT adapter
as near the center of the pipe as possible (see item
labeled “ 2” in
Figure 10, p. 23
). Finger-tighten the
1/2-in. NPT adapter; then, tighten w ith a w rench an
additional 1-1/4 turns.
N ot e: When installed, the tip of the ifm efector sensor
probe m ust be at least 2.54 cm (1 in.) away from
any pipe wall. Placing the tip of the probe at the
center of the pipe is preferred.
3. Install the M icro DC Cable by inserting it through the
w ire openings on the back side of the control panel (see
item labeled “ 3” in
Figure 10, p. 23
). Install the
supplied M icro DC Cable (9 m eters [25 feet] in length)
to the Flow Probe and hand-tighten the connector nut.
4. Plug the other end of the M icro DC Cable into the Flow
Control M onitor w ith the Com bicon connector (see
item labeled “ 4” in
Figure 10, p. 23
). Refer to
Figure 11
for cable w iring.
