WIRING INSTRUCTIONS: 

It is highly recommended to use FloTech FT400 jacketed 5-conductor cable when wiring a 
new system.  FloTech cable is designed to be oil, UV, and abrasion resistant.  We incorporate 
a noble tin plated stranded copper wire which resist corrosion.  These features will provide 
years of reliable service. 
 
After all sensors are mounted in each compartment, align the conduit openings so they face 
the roll over rail.  Thread in cable glands and pull a length of cable through the conduit 
openings between each sensor.  Cut to length leaving approximately 8 inches extra length 
exiting the top of each probe holder. 
 
All sensor wires must enter or leave the probe holder through one of the ½ NPT openings.  
Use FloTech FT402 ½ NPT cable glands to ensure a water tight seal.  Unused conduit 
openings must have a ½ NPT pipe plug installed.  Use pipe dope on all ½ NPT threads to 
ensure a water tight seal. 
 
Wire the sensor according to diagram F1 below.  Double check your wiring connection when 
complete.  NOTE: It is highly recommended to use a small amount of Silicone RTV sealant 
in each crimp connection.  Fill the FloTech butt end crimps with Silicone RTV sealant prior 
to inserting the wires then crimp.  This will provide a watertight and vibration resistant 
connection. 
 
When wiring is complete, replace each sensor lid and o-ring.  CAUTION: Do not pinch a 
sensor wire when installing the lid.
