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
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.

Components:
A. E40174 – 1/2" NPT adapter (for low probe)
B . SF6200 – Flow probe
C . SN0150 – Flow control monitor
D. E70231 – Combicon connectors (quantity 5) 4
E . E10965 – Micro DC cable, 10m length, PUR jacket
F. F53003 – Din rail, 40mm length

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
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
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
for cable w iring.
