a 0 <br /> Probe and Sensor Installation Probe and Sensor Manhole Installation <br /> Probe and Sensor Installation <br /> Probe and Sensor Manhole Installation <br /> At each underground probe and sensor location,install a 14-inch minimum diameter <br /> approved manhole according to the manufacturer's instructions(Note:probes should <br /> be located at least 24 inches from the submersible pump to avoid erroneous probe <br /> readings when the pump is running). <br /> Position the manhole so that there is necessary clearance for junction box installation <br /> and wiring. <br /> Probe and Sensor Installation Diagrams <br /> Each probe and sensor supplied by Veeder-Root is accompanied by an installation <br /> manual.For reference only,Figure 5 contains a composite of the installation diagrams <br /> taken from individual probe and sensor installation manuals.When installing Veeder- <br /> Root probes and sensors you must consult and adhere to the procedures given in the <br /> installation manual shipped with that probe or sensor. <br /> 14"min.dia. <br /> �� manhole <br /> Cord grip seal <br /> supplied with probe <br /> Concrete slab ' <br /> or packed earth a . <br /> per NFPA 80 s— <br /> Epoxy seal per NFPA spec <br /> Riser pipe-4"API schedule 40 1/2"rigid conduit(to Console) <br /> (To prevent erroneous probe readings, 18"min. <br /> install probe riser a minimum of 24" see Weatherproof junction <br /> from the submersible pump.) note box with 1/2"NPT <br /> threads(16 cubic inch <br /> minimum) <br /> "Note: <br /> Increase this minimum dimension if the tank <br /> diameter does not match the probe length. -- Split-ring collar(optional) <br /> (Example: a 7'6" dia. tank will use an 8' — See detail below <br /> probe.
