WaterLine Controls FPT 30-64F Installation Planning

Pre-Installation Planning and Review
Sensor and Control Panel Considerations
 Use the metal of the cooling tower as a barrier from EMF interference (radar, cell, antenna or radio towers).
 Do NOT use the same power source or ground circuit of a VFD.
 Do NOT run the sensor cable within 3" of VFD control wires or high voltage lines.
 If the control panel and/or sensor cannot be out of site of a VFD, then maintain at least 15 feet from VFD panels,
wires.
Rules for High and Low voltage circuits
 Maintain at least 3" spacing between the sensor cable and high voltage lines.
 Do NOT run the sensor cable in the same conduit with high voltage lines.
 When crossing high voltage lines, cross them perpendicularly.
 Do NOT coil excess sensor cable.
Sensor Cable Length
The sensor cable comes in 50-foot increments, starting at 50ft. Order the cable longer than you need it. The sensor
cable should be cut to fit. Be sure to leave enough slack (1 ½ times the length of the longest rod) in the sensor cable
in the event the sensor needs to be removed for maintenance or inspection. If a sensor cable splice is necessary,
contact Waterline Controls to order a splice box enclosure.
 Install the sensor cable in earth grounded metal conduit separate from the earth grounded metal electrical
conduit housing high voltage lines. In those cases where running separate conduit is not plausible then follow
the rules for high and low voltage circuits. Do NOT zip tie the sensor cable to conduit carrying high voltage lines.
Control Panel
 Provide a dedicated 15 to 20-Amp circuit to the control panel. Do NOT share the ground or neutral with other
circuits and by no means should the circuit for a VFD be used.
 We recommend placing the control panel as close to the cooling tower as possible, keeping it above the water
basin and out of sight of any Variable Frequency Drives (VFD).
 The control panel should be mounted in a convenient location where water spray will not impinge upon the unit
and at a height above the tank overflow level to prevent water from feeding into the sensor wire conduit.
 Plan to mount the control panel where the low voltage wire crosses (perpendicularly) the least number of high
voltage circuits.
